Evaluation of cardiomyopathy by late gadolinium-enhanced cardiovascular magnetic resonance imaging
摘要
Abstract
Objective To evaluate the application of late gadolinium- enhanced cardiovascular magnetic resonance (LGE- CMR) images in diagnosis of myocardiopathy. Methods Fifty one patients, including 32 males and 19 females aged 17~79y received LGE- CMR examination during January 2010 and January 2013. The LGE- CMR images were evaluated by two radiologists independently, in terms of LGE locations (subendocardial, transmural, mid- wal , subepicardial) and LGE patterns (spot/spots, linear, patchy). Kappa test for consistency and χ² for the relationship between LGE and cardiomyopathy were per-formed. Results Myocardial lesions were found in 39 cases by clinical fol ow- up or pathology. There was a good consistency in diagnosis, LGE location and pattern between 2 radiologists (Kappa= 0.876, 0.678, 0.686, P<0.05 or 0.01). LGE- CMR wel demonstrated myocardial lesions (χ²=13.226, P<0.05) with a sensitivity, specificity, positive predictive value and negative predic-tive value of 79.5%, 83.3%, 93.9%and 55.6%, respectively. The LGE in ischemic cardiomyopathy was mostly located in suben-docardial or transmural (81.8%) sites, and patchy enhancement was common (72.7%).The LGE in inflammatory cardiomyopathy was mainly situated in mid- wal (75.0%), and spot/spots (3/8), linear (3/8), patchy (2/8) enhancements were al visible. In the non- ischemic cardiomyopathy, LGE signs were in subendocardial, transmural or mid- wal sites, and inclined to be spot/spots- like enhancement. Conclusion LGE- CMR is helpful in evaluation of cardiac lesions and its features in patients with cardiomyopathy.关键词
