Feel-good CT-positive appendicitis cases rarely elude surgery
Patients diagnosed with acute appendicitis at CT sometimes recover enough to skip the surgery and go home. But the miraculous recovery rarely lasts, and most patients end up returning for the appendectomy they'd hoped to avoid, say researchers from the University of California, San Francisco.

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.

Framingham risk doesn't predict plaque burden
Risk factor schemes such as the Framingham risk assessment work fine for patient populations, but they do a poor job of predicting the atherosclerotic plaque burden of individuals, according to a new study by Dr. David Dowe and colleagues in the January American Journal of Roentgenology.

Perfusion CT predicts treatment response for pancreatic cancer
Perfusion CT can predict the response to radiation and chemotherapy treatment in patients with pancreatic cancer, say researchers from South Korea. The group is hopeful that the results can be used to develop therapies tailored to individual patients, potentially improving survival times while minimizing the toxic side effects of therapy.

Sleep cuts coronary artery calcification
It is sleep, wrote William Shakespeare, that "knits up the ravelled sleave of care." But maybe just as important, a new study shows that getting enough sleep prevents coronary artery calcifications, which are strongly associated with morbidity and mortality.

Significant VC dose reduction possible with undersampling
Researchers from the University of Wisconsin aim to take radiation dose reduction to the next level in virtual colonoscopy. By undersampling the number of projections in CT scans, they found they could theoretically reduce dose at least fourfold without hampering image quality.
