Prospective gating drops cardiac CT radiation dose

By Brian Casey

VIENNA - Prospective gating has emerged as a promising method for reducing radiation dose in coronary CT angiography (CTA) studies. Monday at the European Congress of Radiology (ECR), Italian researchers confirmed previous results in using prospective gating to reduce dose to as little as 2.8 mSv per heart study, while a German group discussed its effort to further refine prospective gating by making it more accurate.

CT maintains edge over MRI in liver transplant planning

By Eric Barnes

VIENNA - Researchers from Germany have found that CT still does a better job than MRI of defining critical vasculature for living donor liver transplant planning, thereby enhancing overall safety for the donors. They compared the results of preoperative CT and MR cholangiography in potential liver donors, and presented their findings Monday at the 2008 European Congress of Radiology (ECR).

CAD nabs the flat polyps VC readers may miss

By Eric Barnes

VIENNA - In two studies presented Sunday at the 2008 European Congress of Radiology, investigators tested colon computer-aided detection (CAD) schemes for their ability to find flat lesions. In both, the sensitivity was reassuringly high, though questions remain about the effect of false-positive CAD detections on reader performance and variations in flat polyp morphology.

Mobile DR helps cut ED image transmission times

By Brian Casey

VIENNA - Using a mobile digital radiography (DR) system in the emergency department (ED) ward helped a radiology department at a French hospital cut the amount of time to image ED patients in half, according to a presentation on Sunday at the 2008 European Congress of Radiology. But the department's efforts to make the efficiency gains permanent have been stymied by government regulations on radiation exposure in healthcare facilities.

7-tesla MRI pinpoints ankle damage in marathon runners

By Rob Skelding

VIENNA - Running a 26-mile marathon can cause both painful and painless ankle pathologies, as anyone who has attempted such a feat can attest. New research presented Saturday at the 2008 European Congress of Radiology (ECR) found that 7-tesla MRI scans can give clinicians insight into just how much ankle damage occurs from endurance running.

Dose studies delve into coronary CTA

By Eric Barnes

VIENNA - At the 2008 European Congress of Radiology (ECR) on Saturday, researchers presented a pair of studies that examined the radiation dose of coronary CT angiography (CTA). The first compared the dose of 64-slice CT to that of dual-source CT, and the other examined coronary CTA dose data from a multicenter trial.

CAD provides mixed benefits for DR lung exams

By Brian Casey

VIENNA - A pair of presentations on Saturday at the 2008 European Congress of Radiology on computer-aided detection (CAD) for digital radiography (DR) reported mixed benefits for the software in detecting lung nodules in thoracic exams. The presenters discussed their experiences with a commercially available CAD product and its impact on radiologist performance in analyzing DR lung studies.

Routine CT scanning is most cost-effective for minor head injuries

By Rob Skelding

VIENNA - Trying to be more selective about which patients receive a CT scan following minor head injury may sound like a good idea, but most of the major selective strategies are less cost-effective and riskier to patients than just routinely scanning all such patients. That's according to new data presented Friday at the 2008 European Congress of Radiology (ECR).

Automated patient-based contrast application cuts CTA contrast volume, risk

By Eric Barnes

VIENNA - A work-in-progress application that bases coronary CT angiography (CTA) contrast dose and timing on a patient's individual cardiac output significantly reduces contrast media use and, by extension, the risk of nephropathy, according to a study presented Friday at the 2008 European Congress of Radiology (ECR).

ECR sessions examine DBT's effectiveness

By Brian Casey

VIENNA - A series of presentations on digital breast tomosynthesis (DBT) at the 2008 European Congress of Radiology (ECR) reported encouraging results with the technology. Clinical investigators shared their experiences with DBT systems from four different manufacturers, and reported on the advantages of DBT compared to conventional full-field digital mammography (FFDM).

Learning curve: VC ramps up spring training

By Eric Barnes

A streak of favorable research outcomes, in particular the preliminary National CT Colonography Trial results released in September, seems to be coinciding with expanded training options for virtual colonoscopy. AuntMinnie.com takes a look at a few of these courses for spring/summer 2008. Potential trainees are advised to sign up soon or miss out.
