CTA seen as accurate complement to invasive angiography
By Eric Barnes
Move over angiography. A study to be published this week in the Journal of the American Medical Association concludes that 16-slice multidetector-row CT angiography, while not a fully developed technology, is a highly accurate complement to invasive coronary angiography.

Biotech firm Cell>Point sees promise for oncology SPECT
By Kate Madden Yee
Since its introduction in the 1990s, PET imaging has helped eclipse SPECT, which has long been used for oncology applications but lacks PET's image quality. Biotechnology company Cell>Point, however, hopes to capitalize on the large worldwide installed base of SPECT cameras by developing radiopharmaceuticals in new combinations. Their hope is to make oncology imaging as versatile and accurate on a SPECT system as it is on a PET camera.

MRI sees spinal metastases earlier, but low-dose whole-body MDCT aces skeletal workup
By Eric Barnes
Researchers from the University of Munich in Germany produced two studies that put 16-slice MDCT to the test for detecting musculoskeletal tumors. In the first, MRI was far more sensitive than CT for detecting spinal metastases. However, the second study found that ultra-low-dose CT detected 100% of the osteolytic lesions detected at both standard-dose CT and MRI.

Neuroimaging study bolsters genetic basis for feeling down
By Shalmali Pal
Even on a genetic level, people who suffer from depression may be shouldering a heavy burden. First, they are carriers of a brain anomaly that makes them prone to the disorder. Second, parts of their brain may be stuck in a neurochemical loop, thwarting the ability to regulate negative emotions. Neuroscientists used multiple imaging modalities to study this genetic connection between anatomy, function, and emotion.

MRI after CT cuts need for liver biopsies in cancer patients
By Tracie L. Thompson
NEW ORLEANS - The number of liver lesions detected by MDCT presents a challenge for patient management, especially when the patient already has a primary malignancy. But MRI can significantly reduce the number that might otherwise be headed for biopsy, according to a study presented at the American Roentgen Ray Society (ARRS) meeting.

MDCT, scintigraphy yield very different reads on wrist fractures
By Tracie L. Thompson
Based on a head-to-head comparison with skeletal scintigraphy, British researchers have reluctantly concluded that MDCT probably shouldn't be the next step after initial x-rays fail to show a suspected wrist fracture.

CAD struggles through tagged, subtracted VC data
By Eric Barnes
Radiologists would love to see a virtual colonoscopy exam so easy it doesn't even need a bowel prep. But to pull it off, they'll need a CAD algorithm that doesn't need a bowel prep either. Researchers from Boston's Massachusetts General Hospital take tentative steps toward an easier VC protocol.
