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.

25 years of CT technology advances translate to lower radiation doses

CT radiation doses have been reduced by a factor of two to 10, researchers have reported.

A new imaging system developed by MIT researchers consists of a small ultrasound probe (left) attached to an acquisition and processing module that is a little larger than a smartphone.

AI detects Alzheimer’s on brain perfusion SPECT scans

Subgroup analysis based on lesion size on PCCT images. The red outlined areas highlight the magnified images of lesions. (A-C) PCCT images in a 62-year-old woman with a body mass index (BMI) of 23.6, calculated as weight in kilograms divided by height in meters squared, who was diagnosed with adenocarcinoma. A lesion with a long diameter of 25 mm was identified in the right lower lobe on axial images acquired during the venous phase. For lesions less than or equal to 30 mm, decreasing section thickness improved boundary sharpness and contrast between the necrotic area and enhanced tissue, with optimal visualization at 0.4 mm. (D-F) PCCT images in a 66-year-old man with a BMI of 24.2 who was diagnosed with adenocarcinoma, revealing a lesion with a long diameter of 52 mm in the right lower lobe. For lesions greater than 30 mm, a section thickness of 1 mm demonstrated better contrast and clarity at the boundary of the necrotic area compared with 0.4 mm. This observation supported the selection of an appropriate section thickness for accurate quantification of necrotic regions within the lesion.
