New algorithm to reduce radiation dose in CT imaging

In recent years, advances in CT scanner technology have made perfusion computed tomography (CT) imaging an important diagnostic tool for patients with suspected stroke. Now, researchers at Mayo Clinic are working to reduce radiation dosages used to acquire perfusion and other CT images. Mayo Clinic medical physicist Cynthia McCollough, Ph.D., and her group of researchers presented their findings related to CT dose reduction at the 52nd Annual Meeting of the American Association of Physicists in Medicine on July 20 in Philadelphia. The presentation was entitled "20-Fold Dose Reduction Using a Gradient Adaptive Bilateral Filter: Demonstration Using in Vivo Animal Perfusion CT."

Lack of insurance coverage and fees deter willingness to undergo CTC for colorectal cancer screening

A recent questionnaire submitted to a group of patients at one of the nation's largest general hospitals suggests that a significant number of patients, who have previously refused colorectal cancer screening, are willing to undergo computed tomography colonography (CTC) (or virtual colonoscopy), but not willing to pay for the exam themselves when not covered by insurance, according to a study in the August issue of the American Journal of Roentgenology (www.ajronline.org).

Low radiation CT scans now at Saint Francis Hospital

Patients requiring a CT scan at Saint Francis Hospital will now be exposed to up to 40 percent less radiation than traditional CT scans. The hospital has acquired state-of-the-art GE™ scanning equipment featuring Adaptive Statistical Iterative Reconstruction (ASiR) that uses an advanced image reconstruction technique that makes it possible to dramatically reduce radiation dose without compromising image quality.

Government report questions double use of CT scans at Illinois, Florida hospitals

Chicago Tribune: Doctors at Illinois hospitals are coming under closer scrutiny after a report questioned the use of "double CT scans," which subjected patients to higher radiation. For some procedures, doctors scanned once using a dye once and once without at a rate higher than in other states. "The hospital launched an investigation, and physicians began to focus on curbing use of the scans.

Study suggests Perfusion CT as noninvasive tool in diagnosis of hepatic toxicity

Liver damage is common in patients with tumor following chemotherapy. Although early liver damage causes no symptoms and is reversible in most patients, it occasionally progresses to more severe liver impairment, which may be irreversible, it is thus necessary to demonstrate the presence and severity of drug-related parenchymal changes.
