Coronary artery disease linked to colon cancer
Patients who learn they have coronary artery disease (CAD) might be wise to get more screening. New research links the presence of coronary artery disease at angiography to a high likelihood of colorectal polyps and cancer at colonoscopy. The study in the Journal of the American Medical Association revealed more new information about individual risk factors than about the general association between heart and colon disease.

Slice thickness, reading method don't change VC results
Neither the primary reading method (2D versus 3D) nor reconstruction slice thickness affected VC results in significant ways in a recent study by researchers from the Mayo Clinic in Rochester, MN. The group also found that the novel "virtual dissection" viewing method saved reading time.

Advanced liver imaging shapes surgical strategies
The days of planning liver interventions on the strength of a few CT or MR reconstructions may be numbered. Researchers from Germany and beyond are honing a set of advanced planning tools that not only provide high-resolution color-coded 3D visualization of the liver parenchyma and vasculature, but offer quantitative views of the intrahepatic vessel branching system and the risks of cutting at a given point in the organ.

Study reveals radiologists' odd interactions with lung CAD
It's a good thing that using computer-aided detection (CAD) to find lung nodules at CT has turned out to be worth the effort. Because how radiologists interact with the systems can be mysteriously counterintuitive. New research at California's Stanford University aims to optimize the value of CAD by better understanding radiologists' reactions to it.

Study: Primary 3D VC equivalent to colonoscopy
A British study of symptomatic patients undergoing same-day virtual and conventional colonoscopy found the two methods equivalent for the detection of clinically significant polyps. In fact, the segmentally unblinded results showed that virtual colonoscopy did slightly better than optical colonoscopy for the detection of clinically significant polyps 6 mm and larger.

BMI's importance loses weight in new atherosclerosis study
Experts disagree about which measures of obesity most accurately predict the risk of atherosclerosis. Is the body mass index (BMI) able to predict atherosclerotic disease? Not very well, according to a new study. Using electron beam CT and cardiac MRI, researchers from Dallas found that only the waist-to-hip size ratio was independently associated with atherosclerosis.

CTA predicts functional recovery of the myocardium
A new study shows that coronary CT angiography (CTA) can be useful for predicting the eventual extent of myocardial dysfunction in patients who have had acute myocardial infarction (AMI), and in those who have undergone reperfusion of an infarct-related artery.

Radiologists no match for nodule measurement software
Measuring solitary pulmonary nodules (SPN) isn't a job that can be avoided. Nodule size matters in so many ways. But radiologists may not want to spend their time measuring lung nodules manually because computer algorithms can do it faster and far more accurately, according to researchers in Germany.
