自由呼吸并运动校正延迟强化 MR 成像用于冠心病合并心功能不全患者的研究
The study of single shot PSIR moco late gadolinium enhancement (LGE) cardiovascular MR in patients with coro-nary artery disease combined with heart failure
摘要
Abstract
Objective To investigate the value of single-shot PSIR moco late gadolinium enhancement (LGE) cardi-ovascular MR in patients with coronary artery disease combined with heart failure .Methods From August 2014 to December 2015, 100 patients who were underwent cardiac magnetic resonance imaging (CMR) and suspected of coronary heart disease complicated with cardiac insufficiency were selected , we collected single shot PSIR moco LGE and conventional LGE images . In 41 patients, conventional LGE was abandoned because of image quality issues .The differences of scan time and image quality between single shot PSIR moco LGE and conventional LGE are compared .Results Single shot PSIR moco LGE and conventional LGE exam have high consistency in the detection of myocardial infarction (Kappa =0.97).Compared with the conventional LGE exam, Single shot PSIR moco LGE was faster [(160 ±11)s vs.(330 ±13)s, t =-67.552, P <0.01], and image quality was higher by blinded review ( P <0.01).Single shot PSIR moco LGE can achieve risk stratification in the full cohort ( P <0.01), but conventional LGE did not receive risk stratification because of arrhythmia or inability to hold breath.Conclusion The single shot PSIR moco LGE and conventional LGE have high consistency in myocardial infarction detection and quantification when conventional LGE can be acquired well .The single shot PSIR moco LGE are superior to con -ventional LGE exam in the aspects of acquisition time , image quality and the number of successfully scanned patients .Single shot PSIR moco LGE may be suitable for routine clinical application .关键词
