Extracolonic findings can't be ignored, VC expert says
The presence of extracolonic findings at virtual colonoscopy is a double-edged sword for practitioners, but constitutes a net positive benefit for patients, according to a presentation at the recent International Symposium on Multidetector-Row CT in San Francisco.

New lung cancer staging guidelines reflect improved CT, survival data
Lung cancer staging will undergo important changes following publication this year of the new edition of the tumor, node, and metastasis (TNM) classifications for lung cancer. Although much will improve compared to the current guidelines, thanks in large part to better data, important limitations will remain.

Triple-rule-out CT scans benefit from prospective gating
For patients with nonspecific chest pain, whole-chest low-dose CT scans (also known as triple-rule-out studies) delivered better image quality and far lower radiation dose than comparable retrospectively gated scans, according to a new study in the American Journal of Roentgenology.

ASIR reconstruction sharpens images, slices abdominal CT dose
SAN FRANCISCO - Iterative reconstruction is a hot topic in CT imaging this year. The use of one proprietary method in particular, adaptive statistical iterative reconstruction (ASIR) from GE Healthcare, has significantly reduced body imaging doses in several multicenter studies discussed at this week's International Symposium on Multidetector-Row CT.

Wide-area CT detectors boost some clinical applications
SAN FRANCISCO - Among the more important technical innovations to hit multidetector-row CT of late are wide-area detectors. They come with inherent inefficiencies, but they're powering advances in heart, brain, and pediatric imaging that would not otherwise be feasible.

CMS rejects Medicare coverage for virtual colonoscopy
The U.S. Centers for Medicare and Medicaid Services (CMS) today rejected a proposal to pay for virtual colonoscopy for routine colon cancer screening of Medicare patients in the U.S., saying that VC, while promising for detecting colorectal polyps and cancer, is "not yet ready for widespread screening use."

CT-screened lung cancer patients live longer
CT screening appears to find early-stage lung cancers that would not have been detected with chest x-ray, enabling CT-screened patients to live significantly longer, concludes a new study from Japan.

Two lung CAD systems unaffected by low dose
A face-off between two lung nodule computer-aided detection (CAD) systems found a big difference in sensitivity for detecting solid pulmonary nodules, but it also revealed the good news that nodule detection was unaffected by low-dose scanning. The number of false positives also differed significantly between the two systems, researchers from Germany reported.

FES-PET better than FDG-PET in breast cancer patients
By Will Morton
In a head-to-head comparison, F-18 fluoroestradiol (FES)-PET/CT was better than standard FDG-PET/CT for the initial staging of estrogen receptor-positive breast cancer patients.
