JAMA study finds wide variation in cardiac CTA dose

Coronary CT angiography (CTA) providers are failing to protect their patients from high radiation dose -- with dose levels varying widely between facilities, according to a new multinational study in the Journal of the American Medical Association.

Adding delayed CT aids some trauma diagnoses

In the emergency setting, would the routine acquisition of a delayed scan five minutes after contrast lead to better diagnoses of trauma patients? It pays sometimes but not always to acquire the extra scan, say researchers from Italy, who reviewed images from hundreds of cases of organ injuries.

Ultrasound screens for pancreatic cancer in high-risk populations

SAN FRANCISCO - Ultrasound detected small pancreatic cancers even CT and MRI couldn't visualize in a novel Dutch screening program aimed at high-risk patients with a family history of the disease. The researchers hope to transform their pilot study into a multicenter trial aimed at finding pancreatic cancer in high-risk patients while it's still resectable.

MR colonography separates benign from malignant colonic strictures

Dynamic contrast-enhanced MR colonography can readily distinguish benign from malignant strictures of the colon, according to Danish researchers. They said the technique could solve a diagnostic dilemma in patients with suspected colorectal cancer lesions that prevent them from undergoing conventional colonoscopy before surgery.

MRI beats PET for myocardial evaluation in patients with impaired LV function

While MRI is known to detect more myocardial scarring than PET in patients with occlusive coronary artery disease, a new study suggests that contrast-enhanced MRI can make a critical difference in treatment planning for revascularization candidates with severely impaired left ventricular (LV) function.

Model finds small polyp surveillance safe, cost-effective

A new model analysis concludes that surveillance of small (6- to 9-mm) colorectal polyps is both safe and cost-effective compared to immediate polypectomy, which suffers from relatively high costs, rare complications, and above all a low yield for colorectal cancer in lesions smaller than 10 mm in diameter.

Autopsy study confirms low prevalence of adenomas in youth

A rare autopsy study of more than 3,500 individuals found that the incidence of colorectal adenomas is low in those under 50, but rises sharply in the sixth decade of life. The study, which provides important new information about the natural history of colorectal polyps and cancer in the young, supports current guidelines recommending that screening begin at age 50.

Faster respiratory motion prediction aids radiotherapy

Respiratory motion compensation algorithms are helping to reduce the irradiation of healthy tissues during radiotherapy by compensating for the patient's breathing during treatment. Researchers from Germany have developed new algorithms that reduce the computational burden of motion-tracking algorithms while maintaining accuracy.
