Cardiac MR reveals evidence of subendocardial ischemia in syndrome X
Syndrome X is characterized by a puzzling collection of findings including typical angina on exertion, the suggestion of myocardial ischemia on exercise stress testing, and normal coronary arteries on angiography. A study in The New England Journal of Medicine harnessed cardiac MR's superior resolution to provide a more detailed picture of subendocardial perfusion.

Contrast-enhanced MRI defines risk of breast microcalcifications
Dynamic contrast-enhanced MRI can differentiate benign from malignant breast lesions in women with mammographically detected microcalcifications, perhaps sparing them the need for surgical biopsy, according to U.K. researchers.

FDG-PET signals early response of malignant GI tumors to Gleevec
PET is more accurate than CT for predicting whether patients with advanced gastrointestinal tumors will respond to a promising new chemotherapy drug, according to a study from the Dana Farber Cancer Institute in Boston. Moreover, PET often signals the good news after only a day of therapy, long before the tumor has begun to shrink.
