Catherine CarringtonMRICardiac MR reveals evidence of subendocardial ischemia in syndrome XSyndrome 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.July 21, 2002MRIContrast-enhanced MRI defines risk of breast microcalcificationsDynamic 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.July 21, 2002Molecular ImagingFDG-PET signals early response of malignant GI tumors to GleevecPET 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.June 30, 2002Page 1 of 1Top StoriesMolecular ImagingPET scans tie fast food to altered blood flow in the heartUltraprocessed foods may acutely affect vascular and brain function, researchers report.AIAI boosts rads' identification of incidental PE on CT imagingPractice ManagementHow are technologists dealing with higher vacancy rates?UltrasoundUltrasound screening for vasa previa tied to better pregnancy outcomesDigital X-RayAI could be cost-effective for osteoporosis screening
