The potential of gadolinium (Gd)-DTPA to improve the detection of acute myocardial infarction by MR has been shown in experimental canine studies. To determine its value in humans, we studied five patients 2-17 days after myocardial infarction by using ECG-gated MR before and after administration of 0.1 mmol/kg Gd-DTPA.

An experimental study using Gd-DTAA and Dy-DTPA-BMA. Nilsson S, Wikström G, Ericsson A, Wikström M, Oksendal A, Waldenström A, Hemmingsson A. Acta Radiol, 37(1):27-35, 01 Jan 1996 Cited by: 16 articles | PMID: 8611319 MR Imaging of Reperfused Myocardial Infarction: Comparison of Necrosis-Speciﬁc and Intravascular Contrast Agents in a Cat Model1 PURPOSE: To compare T2-weighted and Gadomer-17– and bis Since MR imaging is already widely accepted as the highest-spatial-resolution measure of infarct size and is feasible in many patients with acute myocardial infarction (13), there is substantial mo-tivation to find an MR imaging method that can be used to measure area at risk. Area at risk measurement would make Molecular imaging of myocardial infarction Cell death: Cell death of cardiomyocytes occurs in the acute phase after myocardial infarction. Imaging of different parameters has been explored: infarct size with small Gd-chelates [1], cell viability with manganese [2], and apoptotic cells with annexin A5-conjugated contrast agents [3]. To evaluate whether 3T clinical MRI with a small-animal coil and gradient-echo (GE) sequence could be used to characterize long-term left ventricular remodelling (LVR) following nonreperfused myocardial infarction (MI) using semi-automatic segmentation software (SASS) in a rat model. Materials and Methods . 5 healthy rats were used to validate left ventricular mass (LVM) measured by MRI with postmortem values.

myocardial infarction MR imaging at 9.4T. Methods Myocardial infarction was induced by permanent ligation of the left coronary artery in male C57Bl/6 mice. 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.

Two days after myocardial infarction, cardiovascular MR imaging was performed on a 9.4T horizontal MR scanner (Varian, Palo Alto, CA, USA), using an eight rod quadrature birdcage transmit/receive coil with an internal diameter of 25 mm and a length of 25 mm (Magnetic Resonance Laboratories, Oxford, UK). To determine its value in humans, we studied five patients 2-17 days after myocardial infarction by using ECG-gated MR before and after administration of 0.1 mmol/kg Gd-DTPA. One patient had a rupture of the interventricular septum, complicating an acute inferior-wall infarction. Magnetic resonance (MR) imaging plays an important role in evaluation of various aspects of myocardial infarction (MI).
