NCT02092428
Investigators at the Biomedical Imaging Research Institute (BIRI) at Cedars-Sinai Medical Center have developed a Magnetic Resonance Imaging (MRI) method for imaging coronary arteries using slow-infusion, contrast-enhanced data acquisition. This method allows faster data acquisition and better spatial resolution. Specific aims of this study are to: 1. compare coronary artery imaging with and without contrast media on both healthy subjects and patients; 2. assess the accuracy of coronary MRI in detecting coronary artery disease as compared to conventional x-ray angiography Researchers hypothesize that contrast-enhanced MRI will improve the delineation of coronary arteries over non-contrast-enhanced MRI and that optimized, contrast-enhanced coronary MRI technique will accurately detect coronary artery disease (CAD) as compared to conventional x-ray angiography.
NCT00115349
The purpose of this study is to determine whether left ventricular function improves more rapidly with deferoxamine (DFO) and deferiprone (L1) combination therapy than with DFO monotherapy in patients with thalassemia and decreased ejection fractions. Secondary aims include evaluating changes in myocardial iron burden using T2\* and estimating the relative incidence and severity of chelator-induced toxicity.
