Advanced CT may have role in noncalcified plaque assessment
Advanced MDCT scanning may be ready to play an important role in assessing noncalcified coronary artery plaque, say German researchers, who used a 256-detector-row scanner and plaque-volume measurement software to compare interobserver variability in patients with different types of plaque.

Extracolonic findings add value to VC screening
In a new study of more than 2,000 patients, virtual colonoscopy found nearly as many cancers outside the colon as inside it. This ability to detect serious extracolonic abnormalities is a major benefit of VC screening, researchers report in the September issue of the American Journal of Roentgenology.

Breast CAD helps find lobular carcinoma in situ lesions
Computer-aided detection (CAD) is making an elusive breast abnormality, lobular carcinoma in situ, a little clearer by highlighting the calcifications that often surround it, according to a new study from Wende Breast Care in Rochester, NY.

AI spots unidentified brain tumor on PET imaging
By Will Morton
An AI algorithm designed for brain PET imaging found a glioblastoma in a patient that had gone undetected by physicians.

Baseline scan (A), segmentation results (B), and follow-up scan (C) from patient with molecular glioblastoma. Baseline MRI showed FLAIR hyperintensities in left thalamus and frontoparietal region (white arrowheads). In contrast to expert segmentation, in which only left thalamic region showed slightly increased uptake (red contour), AI algorithm identified additional frontoparietal lesion on baseline PET that subsequently progressed to contrast-enhancing and metabolically active lesion (red arrowheads).
