Assessment of Left Ventricular Function and Hemodynamics

(c, d) Three-chamber (c) and short-axis (d) delayedenhancement images in another patient show MR imaging was performed to investigate whether Gd-DTPA-BMA-in- duced contrast enhancement of myocardial infarction is counteracted by Dy- DTPA-BMA. Myocardial infarction was induced in 5 pigs. Microdialysate probes were inserted in ischemic and nonischemic myocardium. Gd-DTPA- BMA (0.3 mmol/kg b.w.) and Dy-DTPA-BMA (1 .O mmoVkg b.w.) were ad- Magnetic resonance imaging (MRI) with a gadolinium-based contrast agent offers high spatial resolution and can identify acute myocardial infarction, 12-16 and this technique continues to be improved. MI is clinically silent in as many as 25% of elderly patients, a population in whom 50% of MIs occur; in such patients, the diagnosis is often established only retrospectively by applying Cardiac imaging. For individuals with highly probable or confirmed acute MI, coronary angiography can be used to definitively diagnose or rule out coronary artery disease.

Cardiovascular MR (CMR) and T2 weighted short tau inversion recovery (T2-STIR) imaging have been used to detect IMH and to 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. Keywords: Myocardial viability; magnetic resonance imaging (MRI); coronary DE-MRI identifies AMI/chronic MI, peri-infarct zone, as well as MVO with high OBJECTIVE. Imaging to determine myocardial infarct size is difficult in the emergency setting because the current gold standards, MRI and nuclear medicine Magnetic resonance imaging offers the unique opportunity to directly visualize the size and location of myocardial infarcts (MIs) with excellent spatial resolution.
