The objective of this study was to noninvasively highlight global and local effects of ischemia and reperfusion (I/R) in a rodent model by using contrast enhanced (CE) and cine MRI based on a 1.5 Tesla clinical scanner system as a preliminary study. Rats received a more or less prolonged cardiac ischemia. SR-FLASH and SR-Turbo-FLASH sequences were used to generate perfusion, CE and cine MRI 48h and 6 weeks after I/R. Images were taken with sufficient resolution to have a valid analysis of contrast agend distribution and myocardial func-tion. This setup promises good practicability for further pathophysiological studies.
