Unique MRI warning system protects patients from injury

THE safety of patients undergoing MRI scanning is being stepped up with the launch of a unique metal detection system developed by two Midlands specialists.

The Ferroguard system, designed by Metrasens and Smallfry, is placed near the entrance to an MRI suite and is used to screen patients for metal compounds, which can cause major problems during scanning.

Metrasens’ chief executive, Dr Simon Goodyear, explained: “The central magnet in an MRI scanner has such a powerful attraction to ferrous metals that it can hurl a porter’s trolley across a room or rip a device from the body of a patient. According to recent studies, incidents like this occur in every 1,000 scans so by immediately alerting clinicians to any trace of ferrous metal entering the MRI scanning suite, the Ferroguard system can have a dramatic effect on improving patient safety.”

3T MRI: Highly Effective at Detecting Wrist Ligament Tears, Possibly Eliminating Need for Invasive Arthroscopy

MRI of the wrist at 3T is an effective way to detect wrist ligament tears and in some cases can avoid unnecessary surgery, according to a study performed at Neuroskeletal Imaging in Merritt Island, Florida.

The study included 49 patients who had both 3T MR and arthroscopy; 51 tears were found on arthroscopy. 41 of the 51 tears were also found using 3T MRI. “The resolution with 3T MRI is good. We are able to see the small ligaments a lot better and determine whether or not they are torn,” said Thomas Magee, MD, lead author of the study.

“3T MRI is beneficial to both the patient and the physician. If there is a problem, it provides a road map for the physician to use during surgery and eliminates any type of surgery for those who have normal findings,” said Dr. Magee. “We are able to see bone bruises, cysts and other things that may be pain generators instead of ligament tears,” he said.

MR Arthrography is More Accurate than MR in Diagnosing Shoulder Tears

MR arthrography of the shoulder allows physicians to better identify tears and provides patients with an accurate diagnosis to determine whether or not surgery is needed, according to a study performed at Neuroskeletal Imaging in Merritt Island, Florida.

The study included 150 patients who underwent both 3T MRI and MR arthrography examinations of the shoulder. “We did the study to see if MR, which is noninvasive, works as well as MR arthrography, an invasive procedure that some patients are fearful of having since contrast has to be injected into the shoulder,” said Thomas Magee, MD, lead author of the study. The study found that MR arthrography was more accurate for making a diagnosis. Sensitivity on conventional MRI for anterior labral tears was 83%; for posterior labral tears was 84%; for SLAP tears was 83%; for supraspinatus tendon tears was 92%; and for partial-thickness articular surface tears was 68%. Sensitivity on MR arthrography on the other hand was significantly higher. Sensitivity for anterior labral tears was 98%; for posterior labral tears was 95%; for SLAP tears was 98%; for supraspinatus tendon tears was 100%; and for partial-thickness articular surface tears was 97%. “With MR arthrography we were able to see things with a high degree of accuracy in the shoulder,” said Dr. Magee.

Molecular Imaging Enables Earlier, Individualized Treatment of Thyroid Cancer

Reston, Va.—In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery.

Researchers from the University of Erlangen-N├╝rnberg, Germany, reported in an article in the January issue of The Journal of Nuclear Medicine on the results of a study using a hybrid single photon emission computed tomography-computed tomography (SPECT-CT) camera to determine and locate the spread of cancer cells to nearby lymph nodes.

According to the researchers, the demonstration or exclusion of cancer spread (metastasis) in regional lymph nodes plays a major role in treating the disease since all patients with lymph node metastases are considered to be at high risk for recurrence.

MRI Emerges as Vital Resource in Treatment of Back Pain

Newswise — Magnetic resonance imaging (MRI) is a growing technology providing an increasing number of clinical benefits when used in the evaluation of back pain according to an article in the January 2009 issue of the Journal of the American Academy of Orthopaedic Surgeons. It is predicted that over the next several years, additional technical developments will allow MRI to provide even more useful orthopaedic benefits.

Co-author Victor M. Haughton, MD, department of radiology, University of Wisconsin Hospitals and Clinics says, “Because of the many different ways to gather this important information, MRI can be used to identify or display almost every type of spinal tissue or pathology. The imaging sequence can be modified to meet many different clinical needs.” Those include:
• Back pain
• Infection
• Tumor
• Trauma and vascular disease

Researchers continue to find new ways to apply technologies that were previously used exclusively on other areas of the body. MRI which is considered safe, fast and versatile is now being used in several spinal applications such as:
• intervertebral disk and facet joint degeneration
• spinal canal stenosis
• vascular disorders
• trauma
