Abstract：Objective: To explore the application in coronary artery disease with the use of late gadolinium enhancement on cardiovascular magnetic resonance (LGE-CMR) images. Methods: A total of 19 cases diagnosed as coronary artery disease (CAD) with LGE-CMR images in our hospital between January 2010 to March 2013. were accepted (15 men, 4 women, ages range from 36 to 79 years, median age 57 years), including 5 cases of coronary atherosclerosis, 14 cases of coronary atherosclerotic heart disease. There were 5 patients with acute myocardial infarction and 5 patients with chronic myocardial infarction in the group of coronary atherosclerotic heart disease. 2 radiologists evaluated whether LGE or not, LGE localizations (subendocardial, transmural, mid-wall) and LGE morphology (spot/spots, linear, patchy) independently and blindly, Kappa test for consistency. Results: LGE present/absent, LGE localization and morphology had a good consistency (Kappa=0.908, 0.733, 0.724, P all <0.05) between 2 radiologists. LGE signs were observed in 84.2% (16/19) CAD cases, and 81.25%(13/16) located in subendocardial (7/16) or transmural (6/16). 43.75% (7/16) patchy, 31.25% (5/16) lines and 25.00% (4/16) spot/spots enhancement were seen. Conclusion: LGE-CMR is helpful to detect cardiac lesion and its range on CAD patients and also useful to identify the extent of myocardial lesions.
