Radiographers perform VC with CAD -- and controversy
A new study from London put radiographers in charge of reading virtual colonoscopy (VC) data, with their performance monitored with computer-aided detection as a second reader. The study raises the question of whether it's inappropriate -- or even dangerous -- to allow nonradiologists to screen with VC.

VC radiation dose holds steady overall despite dose modulation
The radiation dose from virtual colonoscopy (VC) hasn't dropped much since the introduction of dose modulation software on CT scanners, largely because VC providers use it only half the time, according to a new study from the Netherlands, which also demonstrated significantly lower doses for VC screening protocols compared to daily practice protocols.

Automated polyp measurement cuts variability
A new study from the Netherlands found that manual polyp measurements in virtual colonoscopy were a bit more accurate than an automated process based on polyp protrusion measurements. The automated scheme still came out ahead, however, because it eliminated interobserver variability.

Ground-glass nodule features on CT reveal malignancy risk
Researchers are peering through a proverbial glass, darkly, to study the features of ground-glass opacities (GGOs). GGOs are being detected with increasing frequency as more thin-section CT lung scans are performed to check for cancer in smokers and former smokers. Distinguishing benign from malignant GGOs is a hit-or-miss task for CT, one that could potentially improve if researchers are able to find reliable signs of malignancy or benignity, thereby reducing the need for invasive biopsy.

Obese patients challenge efficacy of cardiac CTA
VIENNA - Coronary CT angiography (CTA) is proving useful for evaluating most patients with suspected coronary artery disease, particularly since the introduction of 64-slice scanners. But information about CTA's performance in certain subpopulations, such as obese patients, is lacking. Researchers from Belgium studied whether coronary CTA was useful in this patient population, and presented their findings at the 2008 European Congress of Radiology (ECR).

CT maintains edge over MRI in liver transplant planning
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
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.

Dose studies delve into coronary CTA
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.

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

Dual-source CT edges into cardiac SPECT turf
U.S. researchers will use this week's European Congress of Radiology in Vienna to present research that shows dual-source CT making inroads into cardiac functional imaging, an area currently dominated by SPECT. The study moves dual-source coronary CT angiography closer to the holy grail of cardiac imaging -- a test that performs both morphological and functional analysis in a single scan.
