摘要
目的分析3.0T MR心肌延迟强化(LGE)诊断心肌病的价值及影像特点。方法选取2015年6月至2020年6月在本院确诊的48例原发性心肌病患者作为研究对象,所有患者均行心脏核磁共振成像,根据是否进行LGE检查分为LGE组和无LGE组,LGE组36例,无LGE组12例,比较两组患者心脏磁共振成像的影像学参数差异,分析其对心功能分级的影响和影像学特点。结果48例患者经心肌MR对比剂延迟显像后,表现为受累心肌节段延迟强化的患者共有36例,表现为无延迟强化的患者共有12例。LGE组患者年龄低于无LGE组患者,受累节段数、受累节段厚度大于非延迟强化组(P<0.05);LGE形态:共有27例呈局限性强化,占比为75.00%,共有3例呈弥漫性强化,占比为25.00%,LGE最常见于第2节段和第8节段;LGE组患者NYHA分级较高,心功能较差,两组NYHA分级差异有统计学意义(P<0.05)。结论3.0T MR心肌延迟强化在心肌病的诊断与心功能的评估具有较高的应用价值,延迟强化患者的受累节段数、厚度及年龄与非延迟强化患者有明显的不同。
Objective To analyze the value of myocardial 3.0T MR late gadolinium enhancement(LGE)in the diagnosis of cardiomyopathy,and its imaging characteristics.Methods 48 patients with primary cardiomyopathy diagnosed in the hospital between June 2015 and June 2020 were selected as research subjects.All patients were examined with cardiac magnetic resonance imaging,and divided into LGE group(36 cases)and non-LGE group(12 cases)according to whether the patient underwent LGE.The cardiac magnetic resonance imaging parameters of the two groups were comparatively analyzed,and their influence on cardiac function grading and imaging characteristics were analyzed.Results MR LGE showed that among the 48 patients,there were 36 patients with delayed enhancement of affected myocardial segments,and 12 patients without.Patients in the LGE group were younger than those in the non-LGE group,and the number of affected segments and thickness of the affected segment were larger than those in the non-LGE group(P<0.05).For LGE morphology,there were 27 patients with limited enhancement,and 3 patients with diffuse enhancement,accounting for 75.00%and 25.00%,respectively.LGE was common in segment 2 and 8.Patients in the LGE group had higher NYHA grades and worse cardiac function than the non-LGE group(P<0.05).Conclusion 3.0T MR LGE is helpful for the diagnosis of cardiomyopathy and assessment of cardiac function.The number and thickness of affected segments and age of patients with LGE are significantly different from those without.
