摘　　要：目的:探究磁共振实时电影在提高心脏磁共振扫描成功率等方面的价值。方法:选取赣州市人民医院2021年12月—2023年10月收治的144例闭气效果较好的患者作为观察组,另选取同时期健康体检者100例作为对照组,同时给予患者实施传统电影和磁共振实时电影扫描,比较观察不同扫描方法的心功能指标、心功能诊断中的一致性评价及扫描时长等情况,探究磁共振实时电影扫描的诊断价值。结果:不同磁共振扫描方法下的LVEF、LVEDV、LVESD和LVCO对比,差异无统计学意义(P>0.05)。观察组患者的LVEF、LVEDV、LVESD和LVCO与对照组对比,差异有统计学意义(P<0.05)。在一致性分析中,传统电影成像和磁共振实时电影扫描的一致性较高,在心功能评价中,均有良好的价值。实时电影成像的扫描时间明显短于传统电影成像,且实时电影扫描的成功率96.53%高于传统电影扫描的84.03%,差异有统计学意义(P<0.05)。结论:磁共振实时电影在心脏磁共振扫描中,可以实现对心功能的有效评价,还可缩短扫描时间,提高成功率,且对于闭气不好患者,更具有实用性,应用价值较高。Objective Exploring the value of real-time cine magnetic resonance imaging in improving the efficiency of cardiac magnetic resonance imaging.Methods 144 patients with good ventilation effects admitted to Ganzhou People's Hospital from December 2021 to October 2023 were selected as the observation group,and 100 healthy individuals who underwent physical examinations during the same period were selected as the control group.At the same time,patients were given traditional and realtime magnetic resonance imaging(MRI)film scans to compare and observe the cardiac function indicators,consistency evaluation in cardiac function diagnosis,and scan duration of different scanning methods,and explore the diagnostic value of MRI real-time film scans.Results There was no statistically significant difference in LVEF,LVEDV,LVESD and LVCO under different magnetic resonance scanning methods(P>0.05).The LVEF,LVEDV,LVESD and LVCO of the observation group patients were compared with the control group,and the differences were statistically significant(P<0.05).In consistency analysis,traditional cine imaging and real-time magnetic resonance cine scanning had high consistency and good value in cardiac function evaluation.The scanning time of real-time movie imaging was significantly shorter than that of traditional movie imaging,and the success rate of real-time movie scanning is 96.53%,which was significantly higher than 84.03%of traditional movie scanning,with a statistically significant difference(P<0.05).Conclusion Real time magnetic resonance imaging(MRI)in cardiac MRI scanning can effectively evaluate heart function,shorten scanning time,improve success rate,and is more practical and has high application value for patients with poor breath retention.
