The first goal of this study is to compare gadofosveset trisodium--a gadolinium agent that reversibly binds to albumin--to an extracellular contrast agent (Gd-DOTA) for the detection of multiple sclerosis lesions. The second goal is to determine the best postinjection time

Journal of the American College of Cardiology, 62(23), 2205-2214 (2013-09-03)
This study sought to identify the frequency, pattern, and prognostic significance of left ventricular (LV) late gadolinium enhancement (LGE) in patients with atrial fibrillation (AF). There are limited data on the presence, pattern, and prognostic significance of LV myocardial fibrosis

We investigated the evolution of new multiple sclerosis (MS) lesions over time using frequency shifts of the magnetic resonance (MR) signal. Twenty patients with relapsing-remitting MS were serially scanned for 6 months at 1-month intervals. Maps of MR frequency shifts
