ASIR enables big CT dose reductions in the abdomen
By Eric Barnes
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.

Study finds VC cost-effective if tiny polyps are ignored
By Eric Barnes
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.

CAD labels abdominal vessels with improved accuracy
By Eric Barnes
A new computer-aided detection (CAD) algorithm automatically labels abdominal arteries extracted from CT images. The work-in-progress system is more accurate and less dependent on error-prone features than previous CAD schemes, say researchers from Nagoya, Japan.

Procedure volume falls for radiography/fluoroscopy systems
By Brian Casey
Procedure volume for radiography/fluoroscopy (R/F) systems in the U.S. has declined over the past five years, most likely due to increased use of CT for procedures once reserved for R/F, according to a new report released this week by market research firm IMV Medical Information Division.

Extracolonic findings add value to VC screening
By Eric Barnes
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.

Study: Hold the CT for pediatric renal trauma
By AuntMinnie.com staff writers
Physicians often order abdominal CT scans for pediatric patients who have undergone blunt abdominal trauma and have blood in their urine. However, because this procedure has low sensitivity and specificity, not ordering it may be more clinically prudent, according to a report in Urology.

Quantitative image analysis uncovers more living liver donors
By Erik L. Ridley
Quantitative image analysis may be able to significantly increase the number of living liver donors, according to Colorado researchers. Re-evaluation of previously rejected donors with a quantitative image analysis system found that most had suitable anatomy for transplantation.

Perfusion CT finds subtle liver toxicity in chemotherapy patients
By Eric Barnes
A new study from China found that perfusion CT can detect and quantitatively assess microvessel changes associated with liver toxicity in chemotherapy patients. The results could help noninvasively assess early liver damage in cancer patients while obviating the need for a separate scan.
