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.

ACRIN study: Bigger images, slower pace improve VC sensitivity
The best virtual colonoscopy readers don't rush through their cases, and they don't try to squeeze more than one image on the monitor at a time. But sticking to their preferred reading method doesn't help them find more polyps, according to a new analysis of data from the National CT Colonography Trial (ACRIN 6664).

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.

CT screening catches small cell lung cancers earlier
In one of the largest studies yet to focus on a rare type of lung cancer, radiologists from Columbia University in New York City found that CT screening and treatment when indicated may spare the lives of patients with small cell lung cancer.

ACRIN VC trial shows only small differences in bowel preps
There was no runaway winner among the three bowel preps used in the recently published National CT Colonography Trial (ACRIN 6664), but there were certainly differences in how they performed, according to a research team from Arizona.

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.

At CT, not all PE are bad PE
Thanks to advanced CT scanners and the watchful eyes of emergency room physicians, the diagnosis of pulmonary embolism (PE) has risen significantly in recent years. Yet despite all the new PE cases doctors are finding, the mortality rate hasn't budged. Researchers in Rhode Island think they might know why.
