The value of a new cardiac magnetic resonance imaging

PURPOSE: To design a segmented inversion-recovery turbo fast low-angle shot (turboFLASH) magnetic resonance (MR) imaging pulse sequence for the visualization of myocardial infarction, compare this technique with other MR imaging approaches in a canine model of ischemic injury, and evaluate its utility in patients with coronary artery disease. Magnetic resonance (MR) imaging plays an important role in evaluation of various aspects of myocardial infarction (MI). MR imaging is useful in establishing the diagnosis of acute MI, particularly At first, the application of T2-weighted imaging in the clinical setting is used to differentiate acute from chronic myocardial infarction. 22 However, the most important application of MRI ischaemia-related oedema regards the evaluation of ‘salvaged myocardium' (Figure 4). New MRI techniques permit noninvasive assessment of the magnetic susceptibility of tissues and can target tissue iron. Therefore, the investigators hypothesize that MRI imaging of myocardial magnetic susceptibility can map hemorrhagic myocardium.

Mr imaging of myocardial infarction

MR imaging is useful in establishing the diagnosis of acute MI, particularly in patients who present with symptoms of MI but outside the diagnostic time frame of altered cardiac enzyme levels or with clinical features of acute MI but without an angiographic culprit lesion. MR imaging of experimental myocardial infarction. Wikström M(1). Author information: (1)Department of Diagnostic Radiology, Uppsala University Hospital, Sweden. The signal enhancement in MR imaging of normal, infarcted and reperfused myocardium was investigated using different types of contrast agents.

Cardiovascular magnetic resonance evaluation and risk

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.

Clinically unrecognized myocardial infarction detected at MR

(a, b) Two-chamber (a) and shortaxis (b) delayed-enhancement images show near-full-thickness to full-thickness delayed hyperenhancement in the basal, mid, and apical anterior and anteroseptal segments (arrows), in an LAD territory distribution. (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.
