OBJECTIVES The objective of this study was to investigate the renal changes after intravenous administration of a high dose of either iodixanol or iopromide using functional magnetic resonance imaging (MRI) and computed tomography (CT). MATERIALS AND METHODS The study was approved by the institutional committee on animal research. Seventy-two male(More)
PURPOSE To evaluate the feasibility of T1 rho mapping in myocardium at 3T and to determine whether T1 rho mapping could better characterize myocardial injury in end-stage renal disease (ESRD) patients compared to T1 and T2 mapping. MATERIALS AND METHODS T1 rho mapping, T1 mapping, and T2 mapping were performed at 3T on 35 healthy volunteers (15 males, 20(More)
Type 4 cardiorenal syndrome (CRS) is a life-threatening world health problem in which chronic kidney disease leads to progressive cardiovascular disease. In type 4 CRS, cardiac inflammation is an excellent target for both detection and therapy; however, this progression was underestimated by previous studies due to the lack of effective detection methods.(More)
OBJECTIVE Our purpose was to validate an early enhancement time point for accurately measuring the myocardial contrast partition coefficient (lambda) using dynamic-equilibrium magnetic resonance imaging. MATERIALS AND METHODS The pre- and post-contrast longitudinal relaxation rates (reciprocal of T1) of the interventricular septum (R1(m)) and blood pool(More)
The relative incidence of long-term adverse effects between low-osmolar contrast media (LOCM) and iso-osmolar contrast media (IOCM) after coronary angiography is still unclear. We analyzed cardiology patients undergoing coronary angiography from January 2006 to July 2013 using either LOCM (iohexol, iopromide) or IOCM (iodixanol) at a single institution. For(More)
