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.

Therefore, the investigators hypothesize that MRI imaging of myocardial magnetic susceptibility can map hemorrhagic myocardium. 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 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. Abstract Hybrid PET/MR imaging is an emerging imaging modality combining positron emission tomography (PET) and magnetic resonance imaging (MRI) in the same system.

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).

MR imaging of reperfused myocardial infarction: comparison of necrosis-specific and intravascular contrast agents in a cat model. Lee SS(1), Goo HW, Park SB, Lim CH, Gong G, Seo JB, Lim TH. 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. In a cat model of reperfused myocardial infarction, identification of the lateral border zone is therefore possible, and by means of MR imaging we were able to determine the size and distribution of this zone. 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. 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.
