Contrast-enhanced FFDM may have edge over breast MRI December 17, 2012 -- Dual-energy contrast-enhanced full-field digital mammography (FFDM) finds additional cancers in the breast with better specificity than MRI, according to a new study published online in Radiology. The findings suggest that contrast mammography could be a feasible alternative to more expensive breast MRI scans.
Is proton therapy worth the cost for prostate cancer? December 17, 2012 -- Is the use of proton therapy for localized prostate cancer worth the cost? A national study of 30,000 men suggests it might not be. Findings were published online December 14 in the Journal of the National Cancer Institute.
Low-dose CT raises coronary calcium scores; IR corrects them December 17, 2012 -- Low-dose coronary artery calcium (CAC) scores are reliable if iterative reconstruction (IR) is applied to the CT data, according to research presented at RSNA 2012. Dutch researchers found that the technology ensures the accuracy of CAC scores that would otherwise be higher and less predictable than the results of higher-dose CT scans.
CMS proposal could ease payment path for oncology PET tracers December 14, 2012 -- The U.S. Centers for Medicare and Medicaid Services (CMS) this week proposed a new policy that could make it easier for new oncology PET tracers to win reimbursement. PET advocates are disappointed, however, that the change won't apply to tracers used for neurology and cardiology applications.
6-MP displays may offer speed, comfort benefits December 14, 2012 -- A single 6-megapixel (MP) medical display allows for increased radiologist productivity and reduces eye strain during reading sessions compared with two 3-MP displays, researchers from Montefiore Medical Center have found.
Competition intensifies in the VNA market December 14, 2012 -- Vendor-neutral archives (VNAs) have finally moved to the forefront of healthcare IT spending, after years of debate on the value of keeping archiving separate from PACS. As demand for VNAs grows, the market is attracting a host of suppliers with a range of product types and strategies.
CAD helps detect smaller lesions on CT colonography December 14, 2012 -- At a cost of just a minute or two of extra interpretation time, computer-aided detection (CAD) software can significantly improve the performance of experienced readers in finding polyps 6 to 9 mm in size on CT colonography studies, according to a large prospective study published online in Radiology.
Mammography's alleged harms: Separating fact from fiction December 13, 2012 -- Screening mammography is a tool that has been proved to reduce breast cancer death rates, but its effectiveness continues to be disputed by researchers, some of whom have resorted to guesswork to buttress their arguments, according to an opinion piece by mammography experts Dr. László Tabár and Dr. Peter B. Dean.
MBIR finds same nodules as ASIR, at fraction of dose December 13, 2012 -- Second-generation iterative reconstruction software doesn't necessarily improve radiologists' ability to detect lung nodules compared to earlier versions. But the new software permits the same lesion detection power at greatly reduced CT radiation doses, according to a study presented at last month's RSNA 2012 meeting in Chicago.
Professionalism discussions improve residents' understanding December 12, 2012 -- How should medical professionalism be taught to radiology residents? Small group discussions are effective, according to a study presented at the RSNA 2012 annual meeting that focused on teaching the principles of professionalism.
