Esaote’s New Weight-Bearing MRI Improves Imaging For Patients With Pain

CHICAGO--(BUSINESS WIRE)--For many patients, diagnosing their back, hip, or knee pain is best accomplished by imaging anatomy in a weight-bearing, or standing, position. At the 2013 Annual Meeting of the American Academy of Orthopedic Surgeons in Chicago, Esaote introduces the new G-scan Brio with eXP technology to give physicians a cost-effective tool for performing both traditional and weight-bearing musculoskeletal MRI exams.

G-scan Brio is an open, non-claustrophobic musculoskeletal MRI system designed for cost-effective operation and patient comfort. New eXP technology is a combination of hardware and software that enables faster imaging exams while decreasing power consumption and reducing operating costs.

Traditional MRI systems require the patient to lie down on a bed and be transported into an immovable tube for the exam. With G-scan Brio, a patient will lie down on the bed, and then the bed and open magnet both rotate on a central axis, enabling the patient to be examined in a weight-bearing position. Physicians can now compare weight-bearing and traditional supine studies to make the most accurate diagnosis.

“For many patients, their symptoms worsen when they’re standing or in a weight-bearing position,” said Douglas Smith, MD, founder of Musculoskeletal Imaging Consultants in San Antonio, TX. “Traditional MRI systems scan these patients in a recumbent position, which fails to explain their symptoms. Consequently, many patients don’t receive the proper treatment and suffer needlessly.”

New eXP technology combines powerful hardware platform with advanced software to decrease imaging time by as much as 40%, which is critically important when imaging patients with pain. Since many patients have metal implants, new Metal Artifact Reduction sequences minimize metal artifacts associated with MR imaging.

Study: Brain Imaging After Mild Head Injury/Concussion Can Show Lesions

SAN DIEGO, March 12, 2013 /PRNewswire-USNewswire/ -- Brain imaging soon after mild traumatic brain injury (mTBI) or mild concussion can detect tiny lesions that may eventually provide a target for treating people with mTBI, according to a study released today and that will be presented at the American Academy of Neurology's 65th Annual Meeting in San Diego, March 16 to 23, 2013.

Studies of brain tissue once a person has died have shown that different types of lesions are associated with more severe TBI. "Our study suggests that imaging may be used to detect and distinguish between these lesions in a living person with mTBI and this finding has important implications for treatment," said Gunjan Parikh , MD, with the National Institute of Neurological Disorders and Stroke and the University of Maryland R Adams Cowley Shock Trauma Center in Baltimore, MD. Parikh is also a member of the American Academy of Neurology.

The study involved 256 people with an average age of 50 who were admitted to the emergency department at Suburban Hospital in Bethesda and Washington Hospital Center in the District of Columbia after mild head injuries. They underwent magnetic resonance imaging (MRI) brain scans. Of those, 104 had imaging evidence of hemorrhage in the brain (67 percent reported loss of consciousness, and 65 percent reported amnesia, or temporary forgetfulness). People with hemorrhages underwent more detailed brain scans with advanced MRI within an average of 17 hours after the injury.

New Report Establishes Research Guidelines to Evaluate Repeat Medical Imaging - Neiman Institute

WASHINGTON, Feb. 20, 2013 /PRNewswire-USNewswire/ -- It is inaccurate to assert that repeat patient testing is synonymous with excessive and unnecessary health care costs, according to a new report that provides a classification system that can identify useful imaging testing and aid regulators and insurers in developing sensible, effective utilization and payment policies.

The report by the Harvey L. Neiman Health Policy Institute provides guidelines for health policy researchers to evaluate the appropriateness and efficiency of repeat medical imaging tests. One of the report's authors, Neiman Institute CEO and Research Fellow Richard Duszak, M.D., said some health policy influencers and payers have a confusing, ambiguous understanding of what constitutes repeat testing and do not have uniform mechanisms to separate those tests that are valuable and essential from those that have less value.

"This report goes to the heart of what health reform is intended to achieve," said Dr. Duszak. "The goal of health reform is to contain costs without impeding patient access to care. Sometimes, health care delivery and payment policies are shaped by a misconception that repeat testing is, by definition, unnecessary and wasteful. This report clarifies the different types of repeat imaging and provides guidelines that can enable evaluation of which tests bring value to both patients and the health care system."

Medtronic Announces FDA Approval and Launch of Its Advisa MRI Pacemaker System

MINNEAPOLIS – February 13, 2013 – Showcasing its leadership position in pacing technologies, Medtronic, Inc. (NYSE: MDT), today announced the U.S. Food and Drug Administration (FDA) approval and U.S. launch of its Advisa DR MRI™ SureScan® pacing system. The Advisa MRI system is Medtronic’s second-generation MR-Conditional pacemaker and is the first system to combine the most advanced pacing technology with proven MRI access.

MRI is the standard of care in soft tissue imaging, providing information not seen with X-ray, ultrasound or CT scans, and is critical for early detection, diagnosis and treatment. Advisa MRI was specifically tested and approved for use as labeled with MRI scanners in the U.S. Of the 156 patients scanned in the Advisa MRI Clinical Trial, none showed any MRI-related complications. The new system includes an Advisa MRI device and two CapSureFix MRI™ SureScan® leads, which must be used together.

“Your physician can implant a pacemaker with advanced options that will allow for broad access to MRI scanning,” said Dr. J. Rod Gimbel of Cardiology Associates of East Tennessee in Knoxville, Tenn. “MRI is just so very important and traditional pacemakers not FDA approved for MRI scanning often prevent the patient from having an MRI when they need it. With more than 85 percent of pacemaker patients being at least 65 years old and having multiple co morbidities for which MRI may be needed, it’s key that physicians and patients have a pacing system that allows MRI imaging as a diagnostic procedure.”

GE Healthcare Introduces New Cardiac MRI Analysis Software

WAUKESHA, WI –FEBRUARY 4, 2013 – GE Healthcare today announced two new software packages for advanced analysis of cardiovascular magnetic resonance (MR) images: CardiacVX and MR VesselIQ Xpress. Both CardiacVX and MR VesselIQ Xpress were featured in the GE Healthcare booth at the annual meeting of the Society for Cardiac Magnetic Resonance (SCMR) on February 1-2, 2013, in San Francisco, California.

Cardiac MR can provide a wealth of information about the patient’s cardiac condition such as functional parameters, flow, and infarction. However, extracting this information and presenting it in an integrated fashion to the referring physician can be a time-consuming task for the technologist or clinician performing the study. GE Healthcare’s new CardiacVX software delivers fast, intuitive, semi-automatic analysis of key cardiac parameters, allowing the user to create a comprehensive cardiac patient report within a streamlined clinical workflow.

Recently FDA 510(k) cleared, CardiacVX runs on GE Healthcare’s Advantage Workstation (AW), and provides a range of reproducible tools for rapid reviewing and reporting. For example, CardiacVX performs fast left ventricle segmentation and volumetric functional analysis in just two clicks.

Study Indicates that Abdominal CT Scans Not Always Necessary in Children with Blunt Trauma

A recent study conducted by the UC Davis school of Medicine has identified seven factors to lessen radiation exposure in young victims of abdominal trauma. The study encompassed more than 12,000 children throughout the country in the Pediatric Emergency Care Applied Research Network (PECARN) and will be published in the upcoming issue of the Annals of Emergency Medicine.

The study involved children arriving within the networks emergency departments following blunt trauma to their torsos such as may have been sustained in bicycle accdents, falls, or assaults. A number of clinical factors were studied, and seven were identified as correlating with risk for involving a clinically important injury. Among the seven factors were evidence of trauma on the abdomen or chest (such as seat-belt marks), neurological changes, abdominal pain or tenderness, abnormal breath sounds and vomiting.

It was found that children who presented with none of these factors present had only a 0.1 percent chance of having an abdominal injury that required acute intervention. In the majority of these cases a CT scan would not likely have presented any significant clinical information.

Surgical innovation centre conducts study on breast MRI

HAMILTON, Ont. – The Centre for Surgical Invention and Innovation is launching a research project to understand the US radiologist’s perspective on the use of MRI for breast cancer screening, diagnosis, and treatment.

The primary method of screening for breast cancer in the US is mammography and the primary method of treating a cancerous breast lesion is to perform surgical excision with the potential for drug and radiation therapy when an invasive cancer is found.

MRI is used as a secondary screening tool for women with a high-risk for developing breast cancer. It is not commonly used as an imaging modality for women not in the high-risk category.

The Centre for Surgical Invention and Innovation is developing technology to enable the performance of breast biopsy and potentially ablative therapies in the MRI environment. They would like to understand the following:

• General perceptions and attitudes toward breast MRI • Current trends and procedural volumes in MR breast screening and Biopsy • Perspectives on the current clinical and screening pathway for high-risk patients • Attitudes toward MR breast screening and procedures • Current preferred methods for biopsy in the MR environment • Perspectives on reimbursement for these procedures • The role of the clinician in the capital purchase process • Perspectives on the adoption rate (and influencers to the adoption rate) of new technologies in the MR environment • Reactions to a written concept describing a new system to perform breast biopsy and treatment in the MRI environment

Benefits of CT outweigh cancer risks in young adults

OAK BROOK, Ill. – The underlying medical conditions facing young adults who undergo computed tomography (CT) exams represent a significantly greater health risk than that of radiation-induced cancer from CT, according to a new study published online in the journal Radiology.

CT utilization has grown approximately 10 percent annually over the last 15 years in the U.S., raising fears of an increase in radiation-induced cancers. However, discussions of radiation-induced cancer risk often fail to take into account the condition of the patients being imaged, according to Susanna Lee, M.D., Ph.D., chief of women's imaging at Massachusetts General Hospital and assistant professor of radiology at Harvard Medical School in Boston.

"The impetus for our study was the concern that the lay press often focuses on potential harm caused to patients by CT imaging," Dr. Lee said. "Lacking in this discussion is a sense of how sick these patients already are."

To better understand the risks and benefits of CT in young adults, the research team lead by Dr. Lee and researcher Robert L. Zondervan, M.S., analyzed imaging records of patients 18 to 35 years old who underwent chest or abdominopelvic CT exams between 2003 and 2007 at one of three university-affiliated hospitals in Boston. Children and young adults are more susceptible to ionizing radiation and more likely to live for the approximately 10 to 20 years considered necessary to develop a radiation-induced malignancy.

The researchers had access to records from 22,000 patients, including 16,851 chest and 24,112 abdominopelvic CT scans. During the average 5.5-year follow-up period, 7.1 percent of young adults who underwent chest CT and 3.9 percent of those who had abdominopelvic CT died: figures that were much greater than the 0.1 percent long-term risk of death from radiation-induced cancer predicted by statistical models in both groups.

Augmenix Receives FDA Clearance to Market its TraceIT™ Tissue Marker

Augmenix, Inc., an innovative medical technology company focused on utilizing hydrogel technology in the fields of tissue marking and radiation oncology, today announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) to market its TraceIT Tissue Marker, an absorbable tissue marker visible under CT, MR, cone beam and ultrasound imaging modalities. TraceIT Tissue Marker is indicated for use to radiographically mark soft tissue during a surgical procedure or for future surgical procedures. TraceIT hydrogel is intended to mark tissue for at least 3 months after injection.

Radiation oncologists often combine, or fuse, MR and CT images to improve dose planning accuracy. However, most markers do not have equally good visibility on both CT and MR, limiting their usefulness for image fusion. “The excellent dual CT and MR visibility of TraceIT hydrogel will simplify image fusion, allowing for improved soft tissue alignment, resulting in improved radiotherapy plan accuracy and may help with cone beam CT verification during image guided treatment” said Josh Yamada, MD, Radiation Oncologist at Memorial Sloan-Kettering Cancer Center.

TraceIT Tissue Marker is a synthetic hydrogel consisting primarily of water and iodinated cross-linked polyethylene glycol (PEG). Injectable through a fine needle, small hydrogel injections are clearly visible in the lung, breast, prostate and other tissues. The hydrogel remains stable and visible in tissue for three months, long enough for radiotherapy, and then is absorbed and cleared from the body.

FDA Approves Amyvid™ (Florbetapir F 18 Injection) for Use in Patients Being Evaluated for Alzheimer's Disease and Other Causes of Cognitive Decline

INDIANAPOLIS, April 6, 2012 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) and Avid Radiopharmaceuticals, Inc., a wholly owned subsidiary of Lilly, today announced the U.S. Food and Drug Administration (FDA) approval of Amyvid™, a radioactive diagnostic agent indicated for brain imaging of beta-amyloid plaques in patients with cognitive impairment who are being evaluated for Alzheimer's Disease and other causes of cognitive decline.[1] Amyvid binds to amyloid plaques, a hallmark characteristic of Alzheimer's Disease,[2],[3],[4] and is detected using PET scan images of the brain.[1]

A negative Amyvid scan indicates sparse to no amyloid plaques are currently present, which is inconsistent with a neuropathological diagnosis of Alzheimer's Disease and reduces the likelihood that a patient's cognitive impairment is due to Alzheimer's Disease.[2] [5] A positive Amyvid scan indicates moderate to frequent amyloid plaques are present; this amount of amyloid plaque is present in patients with Alzheimer's Disease, but may also be present in patients with other types of neurologic conditions and in older people with normal cognition.[1], [4], [6]

It's important to note that Amyvid is an adjunct to other diagnostic evaluations. A positive Amyvid scan does not establish a diagnosis of Alzheimer's Disease, or other cognitive disorder. Additionally, the safety and effectiveness of Amyvid have not been established for predicting development of dementia or other neurologic condition, or monitoring responses to therapies.[1]

fMRI Technique leads to Mind Reading Speller for those Unable to Speak

Researchers have developed a new MRI based technology that can enable language communication in those completely unable to physically speak. According to an article in Biology Jopurnal of Cell Press, the key to the new technology is the first real time brain scanning speller.

The technology expands on an earlier use of fMRI to assess conciousness in people described as being in an unconcious or vegetative state by introducing the capability of answering simple yes or no questions. Going beyond the earlier version, the new scanning technique uses the entire alphabet as well as blank spaces.

While volunteers performed 27 different mental task with each linked to an alphabetical letter or the space key, blood flow in very precise parts of the brain corresponding to these tasks was measured by fMRI and a deterrmination was made of which character they had chosen.

"The work of Adrian Owen and colleagues led me to wonder whether it might even become possible to use fMRI, mental tasks, and appropriate experimental designs to freely encode thoughts, letter-by-letter, and therewith enable back-and-forth communication in the absence of motor behavior," said Bettina Sorger of Maastricht University in The Netherlands, one of the researchers working on the study.

Study Examines Necessity of Additional Imaging in PET/CT Oncologic Reports

Radiologists and nuclear medicine physicians recommended additional imaging about 30% of the time in oncologic PET/CT reports, with about half of those recommendations being unnecessary, a new study shows.

The study, conducted at Brigham and Women’s Hospital in Boston, included 250 patients. The study found that there were 84 recommendations made for additional imaging. When study reviewers examined the patients’ records, they concluded that 43 of those recommendations were unnecessary, said Atul Shinagare, MD, one of the authors of the study. No adverse patient outcome would have occurred by not recommending additional imaging tests in these 43 cases, said Dr. Shinagare.

The study did not specifically address the motivating factors behind the recommendations for additional imaging, however “we feel that some of the most important factors leading to unnecessary recommendations include reluctance of physicians to accept uncertainty regarding diagnosis, partly driven by medicolegal concerns, combined with a failure to fully consider the patients’ clinical circumstances and the likely cost-effectiveness of additional imaging tests,” said Dr. Shinagare.

The study also found that 70% of the time, referring physicians did not follow through on the radiologists’ recommendation for additional imaging.

Breast MRI helps predict chemotherapy's effectiveness

OAK BROOK, Ill. – Magnetic resonance imaging (MRI) provides an indication of a breast tumor's response to pre-surgical chemotherapy significantly earlier than possible through clinical examination, according to a new study published online in the journal Radiology.

Women with breast cancer often undergo chemotherapy prior to surgery. Research has shown that women who receive this treatment, known as neoadjuvant chemotherapy, are more likely to achieve breast conservation than those receiving chemotherapy after surgery.

Clinicians track a patient's response to neoadjuvant chemotherapy through clinical measurements of the tumor's size and location. Contrast-enhanced MRI offers a promising alternative to the clinical approach through its ability to detect blood vessel formation in tumors, known as angiogenesis. Angiogenesis is an earlier and more accurate marker of tumor response.

"MRI was better than the clinical approach for predicting which patients would go on to have complete tumor response," said Nola M. Hylton, Ph.D., professor of radiology and biomedical imaging at the University of California in San Francisco. "It gave us great information on early response to treatment."

For the study, researchers analyzed data from ACRIN 6657, the imaging component of the multicenter Investigation of Serial Studies to Predict Your Therapeutic Response with Imaging And moLecular Analysis (I-SPY TRIAL) breast cancer trial.

They compared MRI and clinical assessment in 216 female patients ranging in age from 26 to 68 years undergoing neoadjuvant chemotherapy for stage II or III breast cancer. MRI sessions were performed before, during and after administration of a chemotherapy regimen. The researchers correlated imaging results with subsequent laboratory analysis of surgical samples.
