CT speeds antiangiogenesis therapy assessment
CT perfusion imaging can spot significant changes in blood flow and volume soon after administration of antiangiogenic therapy, researchers from Munich, Germany, report in a new animal study. Faster assessment can lead to nimbler, more flexible cancer care compared to traditional tumor size measurements.

Cardiac model favors treadmill then CTA for low-risk patients
A new cost-effectiveness model gives surprising prominence to the exercise treadmill test for evaluating patients with suspected coronary artery disease. In fact, treadmill plus imaging -- especially coronary CT angiography (CTA) for low-risk patients -- was more cost-effective than any imaging modality alone.

Delayed contrast reactions are frequent and underreported
Delayed allergic reactions to CT contrast media occur more frequently than previously reported, says a new study in the June issue of Radiology. Radiologists need to keep an eye out for these patients -- who have often already left the facility -- to counsel them and respond appropriately.

Dual-energy VC aims for noninvasive polyp evaluation
Dual-energy CT may find itself forging a new path in virtual colonoscopy by not only finding colorectal lesions but characterizing them in ways other noninvasive techniques cannot, according to a presentation at the International Society for Computed Tomography conference.

Cardiac CAD safely rules out coronary artery disease
A computer-aided detection (CAD) algorithm that detects coronary artery stenosis at coronary CT angiography not only helped less experienced readers find more lesions, it ruled out adverse cardiac events for more than a year in patients who had disease symptoms but were read by CAD as negative.

MRI boosts diagnosis of constrictive pericarditis
Measuring the early filling fraction can improve MRI's ability to diagnose constrictive pericarditis, according to new research from Michigan and Pennsylvania. The secret to MRI's success lies in its functional measures, which outperform conventional morphologic signs of disease, investigators said.

Appendicitis: Positive CT outweighs lack of symptoms
Patients with CT results suggestive of appendicitis but who have normal clinical presentation should probably proceed to appendectomy sooner to avoid it later, concludes a large retrospective study from the University of California, San Francisco.
