NEJM: Refining lung cancer screening criteria boosts CT efficacy
Lung cancer screening with CT is far more efficient when screening criteria are refined with additional patient risk factors to identify the individuals at highest risk of developing lung cancer who would benefit most from screening, according to a study published in the July 18 issue of the New England Journal of Medicine.

Residents join clinicians on rounds to raise radiology's profile
Radiologists are coming around to the idea that they need to get out of the reading room and in front of patients and referring physicians to improve their visibility. California researchers described their efforts to do just that in a new study published in the Journal of the American College of Radiology.

Extracardiac findings at cardiac CT: How hard to look?
The search for extracardiac abnormalities detected at coronary CT angiography comes with a major decision that depends, as much as anything, on how hard radiologists really want to look for them, according to a presentation at the recent International Symposium on Multidetector-Row CT.

H7N9 bird flu pneumonia scans show common imaging findings
A new bird flu strain known as influenza H7N9 appeared in China this year and quickly took a number of human victims. An article in Radiology published on Tuesday includes some of the first radiologic images of the effects of the virus, revealing typical patterns of progression and regression on CT scans and radiographs of the chest.

Radiation risk matters in cancer screening decisions
CT wins the cost-benefit analysis in most cancer screening tests involving the modality, but the risks of ionizing radiation aren't negligible and should continue to be scrutinized as a factor in screening decisions, according to an article in the July edition of the American Journal of Roentgenology.

Wide-area 640-slice CCTA pares contrast dose
Chinese researchers performing coronary CT angiography (CCTA) on a wide-area CT scanner with 640-slice reconstruction found they could substantially reduce the use of contrast media -- at least in nonobese patients with well-controlled heart rates.

MDCT: Ultralow-dose CT lung scan needs more validation
WASHINGTON, DC - Ultralow-dose lung CT with iterative reconstruction looks to be quite robust, but more validation is needed before imaging facilities make it their mainstay, according to a Wednesday talk at the International Symposium on Multidetector-Row CT.
