Item Open Access Incremental value of PET and MRI in the evaluation of cardiovascular abnormalities.(Insights Imaging, 2016-08) Chalian, Hamid; O'Donnell, James K; Bolen, Michael; Rajiah, PrabhakarThe cardiovascular system is affected by a wide range of pathological processes, including neoplastic, inflammatory, ischemic, and congenital aetiology. Magnetic resonance imaging (MRI) and positron emission tomography (PET) are state-of-the-art imaging modalities used in the evaluation of these cardiovascular disorders. MRI has good spatial and temporal resolutions, tissue characterization and multi-planar imaging/reconstruction capabilities, which makes it useful in the evaluation of cardiac morphology, ventricular and valvar function, disease characterization, and evaluation of myocardial viability. FDG-PET provides valuable information on the metabolic activity of the cardiovascular diseases, including ischemia, inflammation, and neoplasm. MRI and FDG-PET can provide complementary information on the evaluation of several cardiovascular disorders. For example, in cardiac masses, FDG-PET provides the metabolic information for indeterminate cardiac masses. MRI can be used for localizing and characterizing abnormal hypermetabolic foci identified incidentally on PET scan and also for local staging. A recent advance in imaging technology has been the development of integrated PET/MRI systems that utilize the advantages of PET and MRI in a single examination. The goal of this manuscript is to provide a comprehensive review on the incremental value of PET and MRI in the evaluation of cardiovascular diseases. MAIN MESSAGES: • MRI has good spatial and temporal resolutions, tissue characterization, and multi-planar reconstruction • FDG-PET provides valuable information on the metabolic activity of cardiovascular disorders • PET and MRI provide complementary information on the evaluation of cardiovascular disorders.Item Open Access Monoclonal Gammopathy of Undetermined Significance and Multiple Myeloma in Older Adults.(Clin Geriatr Med, 2016-02) Guerard, Emily J; Tuchman, Sascha AMultiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) are plasma cell disorders of aging. The landscape of the diagnosis and management of MM and MGUS are rapidly changing. This article provides an updated understanding of the clinical presentation, evaluation, diagnosis, and management of older adults with MM and MGUS. Because most oncology providers are not formally trained in geriatric medicine, geriatricians play a key role in providing oncologists with a broader understanding of patient health status in the hope of improving outcomes for older adults with MM.
