PET - CT Can Help Detect Curable Cause of High Blood Pressure

Researchers at the University of Cambridge have developed a new test that could help doctors diagnose thousands of people with hypertension. While for most people with hypertension there is no discernible cause, in a small number of people there is a specific condition which causes blood pressure to rise. One such condition is known as Conn's syndrome, and this is the condition which researchers have been able to target with PET - CT scanning.

Conn's syndrome is caused by a benign tumor called an adenoma in one of the adrenal glands. The tumor causes over-production of a key blood pressure-regulating hormone called aldosterone and once diagnosed can be treated surgically or with medication.

The new test, studied on patients at Addenbrooke’s Hospital in Cambridge, requires scanning the abdomen using positron emission tomography with x-ray computer tomography technology. The scanning technique isd more commonly known as a PET-CT and is frequently used in cancer diagnosis. Researchers have developed a special radioactive tracer called 11C-metomidate, which "lights up" the adenomas in the scan. The test takes around 45 minutes.

The initial study has been published online in the Journal of Clinical Endocrinology and Metabolism. The work was funded mainly by the British Heart Foundation and the National Institute for Health Research (NIHR), the research funding arm of the NHS.


Philips Receives FDA Clearance to Market Its First Whole Body PET/MR Imaging System in the United States

CHICAGO, Nov. 28, 2011 /PRNewswire via COMTEX/ -- Royal Philips Electronics PHG -0.27% (aex:PHI) is announcing 510(k) clearance from the Food and Drug Administration (FDA) for the company's first commercially available whole body positron emission tomography/magnetic resonance (PET/MR) imaging system, the Ingenuity TF PET/MR. This leading edge platform will redefine how medicine is practiced in the future by helping clinicians and researchers investigate novel personalized medicine and treatments for oncology, cardiology and neurology. The system is on display at the 97th annual meeting of the Radiological Society of North America (RSNA), November 27 - December 2.

It was previously thought that PET and MR scans were incompatible; however, Philips overcame the enormous technical hurdles, through advances in technology, to create a new class of hybrid imaging that will push the bounds of what's possible in imaging. The system is designed to provide a state-of-the-art platform well into the future by facilitating the addition of new technologies as they become available.

The Ingenuity TF PET/MR delivers increased economic value, as it is a sequential imaging system that has a similar clinical workflow experience to PET/CT, the current benchmark for hybrid imaging. In addition, the system is designed so the patient table rotates between each modality to scan a patient, thus enabling the system to perform both standalone MR and hybrid PET/MR studies.

Digital ArtForms Debuts iMedic3D at RSNA '11

CHICAGO, Nov. 25, 2011 /PRNewswire via COMTEX/ -- RSNA '11 -- Digital ArtForms announces iMedic3D, the first in a new generation of imaging tools, as well as the addition of Dr Eliot Siegel and Dr David H Kim to its Advisory Board.

"iMedic3D brings immersive interaction to medical imaging. By replacing the 2D mouse with a pair of 3D mice, we empower radiologists and surgeons to better visualize and interact with their 3D datasets," said Paul Mlyniec, President of Digital ArtForms.

"I'm proud to welcome Drs. Siegel and Kim to our Advisory Board. We are delighted that two such distinguished radiologists are so enthusiastic about iMedic3D, and we look forward to their considerable contributions to its development and acceptance. With their help, we believe we can change the face of Radiology. We are confident that the clinicians visiting with us at RSNA '11 will agree," said Mlyniec.

"The mouse and keyboard interface for imaging systems, including the PACS, has been essentially unchanged since the early 1990s," said Dr Siegel. "... Digital ArtForms' tracked interface ... seems to be a truly innovative and an out of the box concept for interaction with complex CT and MRI datasets. It becomes intuitive after a few minutes of practice, and I believe that it has the potential to provide a more efficient and effective interface if workstation vendors can support its many degrees of freedom of motion."

"The tracked interface is a paradigm shift in interpretation that makes sense," said Dr. Kim. "It supports cross-sectional evaluation and extends naturally to manipulating volumetric data. In my opinion, this is clearly the future of radiology."
