SCCT: Dual-energy CTA may offer more accurate look at plaque July 24, 2012 -- A new dual-energy CT angiography (DECTA) protocol may provide a more accurate look at coronary artery calcium by eliminating artifacts that can bedevil more conventional CTA approaches, according to researchers from Virginia at this week's Society of Cardiovascular Computed Tomography (SCCT) meeting in Baltimore.
ABUS equals MRI as screening option for dense tissue July 24, 2012 -- Automated breast ultrasound (ABUS) shows promise as a cost-effective adjunct screening modality compared to MRI for women who have dense breast tissue at mammography, according to a study published this month in the Journal of Diagnostic Medical Sonography.
CMS takes feedback to modify PET agent review process July 23, 2012 -- Agreeing to a request from five medical imaging organizations, the U.S. Centers for Medicare and Medicaid Services (CMS) has begun taking public comment on a proposal to streamline the process by which PET imaging agents are reviewed and approved for reimbursement.
Cost vs. benefit determines choice between 1.5T and 3T MRI July 23, 2012 -- Purchasing a new MRI system is a substantial investment, and deciding whether to invest in a 1.5- or 3-tesla system requires careful consideration of some key factors. Two facilities, one a small medical center and the other a large hospital, share their experiences of how they made their choice.
ACC-based software boosts appropriateness of heart scans July 23, 2012 -- American College of Radiology guidelines aren't the only ones being used to develop software to rein in inappropriate utilization. A new decision-support tool based on American College of Cardiology (ACC) appropriateness criteria demonstrated its value in reducing unnecessary cardiac imaging exams in a recently completed pilot project.
Structured radiology reports reduce error rate July 20, 2012 -- It's assumed that implementing structured reports in a radiology department has a number of benefits, including consistency and understandability of content, more complete reports, increased workflow efficiency, and fewer errors. But how valid are these assumptions?
PiB, FDG-PET change diagnosis for dementia patients July 20, 2012 -- A new study by Dutch researchers adds evidence that PET imaging with carbon-11-labeled Pittsburgh Compound B (PiB) and FDG can lead to early diagnosis of Alzheimer's disease and differentiate between specific dementias, especially when previous diagnostic certainty is low.
