CT often unjustified in the young; German pediatricians lack dose awareness
VIENNA - About a third of the CT scans performed in patients younger than 35 could be replaced by other modalities, concludes a Norwegian study presented Tuesday at the European Congress of Radiology. Meanwhile, a survey in the region of Essen, Germany, found that many pediatricians lack basic knowledge of radiation exposures for various chest indications.

NELSON lung cancer trial yields positive early results
VIENNA - A first peek at the first results of the first large randomized lung cancer screening trial to near completion found that CT detected four-fifths of participants' lung cancers at stage I -- in time to effect a curative resection.

Diabetes renders coronary CTA more difficult, less successful
VIENNA - Diabetic patients have smaller vessels and larger coronary artery calcifications than nondiabetics, a combination that reduces the utility of coronary CT angiography (CTA), according to a new study from Italy.

3D CT detection of perfusion defects mirrors SPECT
VIENNA - Three-dimensional images from normal coronary CT angiography scans are highly sensitive for detecting fixed perfusion defects compared to myocardial SPECT. A special reconstruction technique performed with customized software does the job without the need for additional radiation or contrast.

Minimal prep VC nearly as sensitive, better tolerated
VIENNA - A new study from the U.S. and Japan found that full-laxative and minimum-laxative virtual colonoscopy had equivalent sensitivities for detecting colorectal polyps 6 mm and larger, though specificity fell in the minimum-prep regimen. The patients were happy to skip the laxatives, however.

320-slice coronary CTA permits much lower contrast dose
VIENNA - Single-beat scanning not only enables significant radiation dose reductions in coronary CT angiography (CTA), the short duration of the scan permits drastically lower contrast doses as well, at least in patients with regular heartbeats and no arrhythmias.

Adding CAD to virtual colonoscopy saves lives and money
Adding computer-aided detection (CAD) increases the efficiency and cost-effectiveness of VC screening, according to a new model-based analysis. Most of the gains resulted from the use of CAD with inexperienced readers, but even with experienced readers VC cost-effectiveness improved substantially.

MRI, MDCT err in estimating cardiac functional parameters
MRI and MDCT assessments of left ventricular functional parameters were inaccurate when evaluated on a moving heart phantom with known parameters, according to a study in European Radiology. CT, particularly dual-source CT, did outperform MRI, however.

320-detector-row CT cuts dose in triple rule-out exams
Image quality is high and radiation dose is low when the so-called triple rule-out protocol is used with 320-detector-row CT to scan patients with chest pain, according to researchers from Berlin.

Virtual colonoscopy beginners do better with 3D data
Novice virtual colonoscopy readers detect more polyps reading 3D endoluminal datasets of electronically cleansed data compared to 2D images. But experienced readers aren't daunted by either 2D datasets or fecal residues, turning in a similar performance regardless of the reading environment.
