Report from ASCO: Studies reveal pros and cons of breast MRIMRI’s changing status as an instrument for breast cancer diagnosis and evaluation was apparent last month at the 2008 American Society of Clinical Oncology meeting. One study suggested that MR’s growing popularity for treatment planning may had led to more mastectomies, and another trial added to growing evidence about its ability to identify metastatic lymph nodes.

FDG-PET imaging tackles large arteries with atherosclerosisA noninvasive technique to detect vulnerable atherosclerotic plaque is critically needed. Formation of atherosclerotic plaque is a dynamic inflammatory process that involves interactions between atherogenic lipoproteins and macrophages. As vulnerable plaques are usually numerous, extending beyond the culprit plaque and involving multiple vessels, targeting a single plaque underestimates the complexity and extent of disease. Thus, an ideal imaging modality should be able to identify the vulnerable arterial bed and, therefore, the vulnerable patient, to prevent the serious complications of atherosclerosis.
