Accurate, fast soft-plaque measurement seen with coronary CTA
Automated measurement of soft plaque in the heart using coronary CT angiography (CTA) was accurate compared to the gold-standard modality, intravascular ultrasound, and was far faster than manual methods, concluded a new report published online this month in Radiology.

Bundling of CAD software boosts lung lesion detection at CT
Running CT lung images through multiple computer-aided detection (CAD) applications delivers better results than any single algorithm alone, researchers are finding. This phenomenon is unleashing a minitrend that may be discomforting to CAD developers concerned about the success of their systems.

CAD algorithm spots acute intracranial hemorrhage
In stroke treatment, time is brain, as they say, but the timely detection of acute intracranial hemorrhage can be difficult when dealing with subcentimeter lesions or inexperienced readers. A new computer-aided detection (CAD) system designed to detect blood clots in the brain could be a welcome addition.

Advanced VC tool serves up polyp locations for colonoscopy
Large polyps found at virtual colonoscopy are referred to optical colonoscopy for removal, and that's generally the end of the story. But VC-detected polyps can't always be found quickly and easily at colonoscopy, so an automated method of finding them might be just what the gastroenterologist ordered.

ASIR enables big CT dose reductions in the abdomen
Adaptive statistical iterative reconstruction (ASIR) of CT data cuts noise and boosts diagnostic confidence of abdominal lesions while slashing radiation dose, reported researchers who used an ASIR algorithm instead of traditional filtered back projection.

Contrast-removal device may reduce CIN risk
A catheter-based device that drains contrast media from the heart after angiography and other interventional procedures have been completed could cut the risk of contrast-induced nephropathy (CIN), according to researchers from Australia.

Study finds VC cost-effective if tiny polyps are ignored
Virtual colonoscopy is cost-effective for colorectal cancer screening, assuming that only patients with polyps 6 mm or larger are referred for polypectomy, a new French study has concluded. Removing the smallest lesions is not only prohibitively expensive, the yield in terms of additional cancer is minimal.
