3D contrast MRA may be optimal for evaluating aortic dissection
By Shalmali Pal
Three-dimensional contrast-enhanced MR angiography (3D CE-MRA) is the way to go for diagnosing and treating aortic dissection, according to a group from Changhai Hospital in Shanghai, China. The advantages of 3D CE-MRA in this setting are its speed, efficacy, and noninvasiveness.

MDCT detects PE incidentally
By Eric Barnes
Unsuspected pulmonary embolism is more common than previously reported, according to researchers from Italy, who found a high prevalence of incidentally detected PE using thin-slice multidetector-row CT. Fortunately, the group also reported in a later study, preclinical probability can be a fairly reliable pretest indicator of PE risk.

Preop MRI to measure CBF may benefit neonates with heart defects
By Shalmali Pal
Advances in neonatal cardiac surgery have vastly improved newborn survival rates, but impaired neurodevelopment and neurological damage remain major concerns in these high-risk patients. Researchers from Philadelphia have found that using MRI to measure cerebral blood flow in severe cases of congenital heart defects may identify a preoperative risk factor for poor neurocognitive outcome.

Digital hand atlas throws up puzzling results versus G&P atlas
By N. Shivapriya
Since the 1950s, the Greulich and Pyle (G&P) atlas has been the standard reference for assessing bone age in children, and subsequently diagnosing growth disorders. But new research hints that the G&P atlas may not accurately reflect the skeletal development of today's children because of increasing racial diversity and changing nutrition and behavior.

Early arterial phase best for HCC detection
By Eric Barnes
Early arterial-phase imaging may be optimal for detecting hepatocellular carcinoma with CT, but once the lesion is found you'll want to add a few seconds' delay to assess tumor hemodynamics, according to a presentation at the RSNA meeting in Chicago earlier this month.

Studies examine osteoporosis management in women with fractures
By Shalmali Pal
Doctors often overlook osteoporosis and its associated risks in women who present with fractures, according to two recent studies. The first looked at bone mineral density (BMD) thresholds for pharmacologic intervention to prevent fractures. The second evaluated the management of osteoporosis in fracture patients.

PET, SPECT show MMSE to be poor prognosticator of Alzheimer's
By Jonathan S. Batchelor
The Mini-Mental State Examination (MMSE) is widely used to assess the severity of dementia. But in comparing MMSE scores with PET and SPECT results of Alzheimer's patients, researchers from the University of Kansas Medical Center found that the MMSE poorly predicted the severity of imaging results, and that evaluating dementia with PET and SPECT may hasten Alzheimer's diagnoses.

Study compares eight digital x-ray systems in clinical setting
By Tracie L. Thompson
Over a relatively brief time period, the medical imaging industry has seen the development of a number of different x-ray systems with varying approaches to x-ray detection. But do differences in detector technology equate to differences in diagnostic performance? The latest answer from one group of Dutch researchers appears to be a qualified yes.

Lower limb US comparable to serial for DVT
By N. Shivapriya
A complete lower limb compression ultrasound can exclude clinically significant deep venous thrombosis (DVT), rendering a serial ultrasound exam unnecessary, according to researchers from New Zealand.

Low-prep VC study finds CAD can be fooled
By Eric Barnes
Computer-aided detection found most of the polyps in a reduced-prep virtual colonoscopy protocol, a new study concludes. On the other hand, the technique produced too many false-positives when barium fecal tagging was incomplete, which was often.
