Objective: To investigate the clinic value of cardiac magnetic resonance(CMR) in diagnosis of ischemic cardiomyopathy. Methods: Thirty-two patients diagnosed ischemic cardiomyopathy clinically underwent MRI plain scan and Gd-DTPA dynamic enhancement scan. The results were analysed by cardiac post-processing software, cardiac functional parameters such as left ventricular ejection fraction were calculated. Cardiac morphology, motion, perfusion and delayed-enhancement were analysed to assess its clinical application value. Results: Cardiac functional parameters of all patients were decreased, including left ventricular ejection fraction, stroke volume, cardiac output and wall thickening rate. There was no significant difference between cardiac magnetic resonance and echocardiography(49%±5.3% vs 52% ± 8.2%; 42.8 mL ± 8.9 mL vs 45.7 mL ± 10.6 mL; 3.5 L/min± 0.6 L/min vs 3.8 L/min± 0.9L/min; 28% ± 4%. vs 31% ±6%, P >0.05). 184 segments(184/544) showed abnormal wall motion in all patients, among these segments, the segments of signal decreasing and delayed-enhancement were136 and 98 respectively. Conclusion: Multimodality CMR provides important information of myocardial morphology and function in diagnosis and prognosis evaluation for ischemic cardiomyopathy. [ABSTRACT FROM AUTHOR]

In recent years, ultrasound(US), CT coronary angiography(CCTA), intravascular ultrasound(IVUS), optical coherence tomography(OCT), multi-slice spiral CT(MSCT), single photon emission computed tomography(SPECT). Positron emission tomography(PET) and cardiac magnetic resonance(CMR) and other cardiovascular imaging techniques can provide important information on anatomy, hemodynamics, cytobiology and pathophysiology. It is playing an increasingly important role in the diagnosis, treatment and prognosis evaluation of ischemic cardiomyopathy. However, how to properly select multi-modal cardiovascular imaging techniques is a major problem for clinicians. Therefore, on the basis of summarizing the clinical application of major cardiovascular imaging techniques,the clinical value of multimodal cardiovascular imaging in coronary artery anatomy and plaque imaging, myocardial function, myocardial perfusion and myocardial viability is reviewed. It aims to help clinicians to objectively understand the advantages and disadvantages of various imaging techniques so as to make optimal choices. [ABSTRACT FROM AUTHOR]
