Enhanced reference standard boosts CTA accuracy
Borrowing a technique from the virtual colonoscopy playbook, researchers from South Carolina and Germany found that coronary CT angiography (CTA) is better than previously thought compared to catheter-based coronary angiography -- in fact the two tests are essentially equivalent, they said.

Workshop yields big drop in scan radiation dose
Scan data from 10 radiology practices in Australia showed that attendance at a radiation dose-optimization workshop nearly halved the doses subsequently given to patients, according to a study published online in the Journal of the American College of Radiology.

Contrast US processing tool shows malignant liver lesions
Swiss researchers have developed a real-time parametric imaging technique for distinguishing benign from malignant liver lesions easily and noninvasively using contrast-enhanced ultrasound. In its first clinical run, the method delivered high sensitivity and specificity in a patient cohort.

Supersized CONFIRM trial tackles coronary CTA and mortality
In a study that probes what may be the largest database of detailed coronary CT angiography (CTA) results assembled to date, New York City researchers found an integral association between coronary artery disease and mortality at coronary CTA in patients without known heart disease.

VC not cost-effective -- unless screening rates rise
In a new model analysis published Tuesday in the Journal of the National Cancer Institute, virtual colonoscopy was generally less cost-effective than several other colon cancer screening tests, including conventional colonoscopy. However, VC would become the most cost-effective test if it were to increase colon cancer screening rates.

Newer dosimeters find big errors in head CT perfusion doses
Traditional radiation dose measurements are grossly inaccurate for perfusion CT head scans, which are being performed with increasing frequency for patients with suspected stroke, according to a study presented on July 22 at the American Association of Physicists in Medicine meeting in Philadelphia.

Pancreatic CT pitfalls can be avoided
Evaluating pancreatic CT images to determine resectability is one of the more difficult jobs in radiology, perhaps more so because the stakes are so high. But a lot of mistakes can be avoided with 3D imaging and careful attention to a few details.

Conebeam reconstruction method speeds processing, cuts dose
A new processing method for conebeam CT images promises to dramatically lower radiation exposure for patients undergoing perfusion CT prior to image-guided radiation therapy, according to a study presented at the American Association of Physicists in Medicine meeting in Philadelphia.
