Purpose:Myocardial infarctions were induced in 12 pigs to investigate whether a double-contrast method, combining a positive and a negative MR contrast agent, could improve the visualization of rep

MR imaging was performed at 9.4T (horizontal-bore MR scanner, Varian, Palo Alto, CA, USA) using a quadrature transmit Myocardium from Chronic Myocardial Scar: The Value of Contrast-Enhanced SSFP-Based Cine MR Imaging The purpose of this study is to demonstrate whether the signal intensity (SI) of myocardial infarction (MI) on contrast enhanced (CE)-cine MRI is useful for differ-entiating recently infarcted myocardium from chronic scar. This study included 24 To investigate whether Gd-DTPA-BMA-enhanced MR imaging permits differentiation between reperfused and nonreperfused myocardial infarction, myocardial infarction was induced in 12 domestic pigs. In All animals survived and completed imaging. Infarction was achieved in 18/20 subjects. Fused PET/MR yielded an imaging correlation of elevated FDG tracer activity within regions of myocardial infarction but reduced activity in regions of microvascular obstruction.

Author information: (1)Department of Radiology, Asan Medical Center, University of Ulsan College of Medicine, 388-1 Poongnap-Dong, Songpa-Ku, Seoul 138-736, Korea. Imaging delayed hyperenhancement of myocardial infarction is most commonly performed using an inversion recovery (IR) prepared 2D breathhold segmented k ‐space gradient echo (FGRE) sequence. Since only one slice is acquired per breathhold in this technique, 12–16 successive breathholds are required for complete anatomical coverage of the heart. 2004-04-26 · Fast, three-dimensional free-breathing MR imaging of myocardial infarction: A feasibility study. Manojkumar Saranathan 1,*, Carlos E. Rochitte 2 and; MR IMAGING OF ACUTE MYOCARDIAL INFARCTION IN PIGS USING Gd-DTPA-LABELED DEXTRAN M. WIKSTROM, H. J. MARTINUSSEN, G. WIKSTROM, A. ERICSSON, R. NYMAN, A. WALDENSTROM and A. HEMMINGSSON Abstract Myocardial infarctions were induced in 12 pigs.

Seven pigs were studied before and after myocardial infarction. PBV measurement was validated in a phantom and calculated as the product of cardiac output determined with velocity-encoded MR imaging and the pulmonary transit time for an intravenous bolus of contrast material to pass through the pulmonary circulation.
