In the past, a person with chest pain entering the emergency department at the Hospital of the University of Pennsylvania could spend up to six hours there before being discharged.

We continue to be both amazed and intrigued by the hype showered on cardiac CT angiography and the corresponding lack of hype given to peripheral vascular CTA. No doubt, 64-slice cardiac or coronary CTA is potentially a revolutionizing technology, but PV-CTA has already revolutionized the comprehensive diagnosis and treatment of peripheral vascular disease.

This spring, the first sites in the world will begin using Philips Medical Systems' newly minted BrightView family of gamma cameras. The compact dual-head product, unveiled at the 2006 RSNA meeting, shines at the high end of the company's nuclear medicine portfolio in performance and versatility.

Multiplanar SPECT/CT lymphoscintigraphy provides better sentinel node detection in patients diagnosed with breast cancer than planar imaging alone, according to a study in the February issue of the Journal of Nuclear Medicine. The technique shows particular promise for overweight patients.

The last time medicine had a new “ray” was back when radioactivity was king, spawning nuclear medicine and grade-B sci-fi flicks. Before the gamma ray was the x-ray . . . and that goes way back.

Expanded coverage for PET drove demand for procedures in 2006, helping push unit sales, which also benefited from local pressures on providers to keep up with the competition. Demand for upgrading the installed base to PET/CT from dedicated PET could bolster sales in the near term, just as the popularity of the modality continues to rise.

Italian computer-aided detection and imaging device company iM3D is slated to begin selling its CADColon iM3D system in this country this quarter. The company, which introduced itself to the U.S. radiology community in 2005 under the moniker iMED Medical Imaging Lab, is already selling CADColon in Europe and is awaiting approval from the FDA for marketing in the U.S. It plans to sell the product directly to customers but is also exploring relationships with imaging vendors interested in building its CAD algorithm into their workstations, said Alessandro Zuccato, head of sales.

Although MR colonography is proving to be an effective method of colorectal screening, patients are no more likely to accept it than optical colonoscopy. In addition, limited bowel prep protocols for CT colonography are proving comparable to full cathartic prep.

Contrast-enhanced lymphosonography finds more sentinel lymph nodes than can established nuclear medicine techniques, according to preliminary animal studies focusing on melanoma.

Researchers at Emory University have demonstrated the uptake of a new radiotracer known as FACBC in both primary and metastatic prostate cancer on initial staging, as well as in recurrent cancer within the prostate bed, lymph nodes, and bone. They reported their findings in the January issue of the Journal of Nuclear Medicine.

Software designed by researchers at the University of Chicago helps detect interval changes in successive nuclear medicine bone scans and can reduce interpretation time by up to 32%, according to research presented in an educational exhibit at the RSNA meeting.

A small outcomes study presented at the RSNA meeting has shown that multislice cardiac CT can be applied in specific ways to eliminate unnecessary cardiac catheterizations for coronary artery disease.

CT advances have knocked the imaging community back on its heels. The simplistic question of who will control coronary CT angiography has given way to far more perplexing ones about how and when this technology should be used.

Plaque buildup in the coronary arteries seen on 16- and 64-slice CT angiography does not always mean blood flow to the heart is restricted, according to research conducted at the Leiden University Medical Center in the Netherlands.
