摘要

目的 探讨MRI人工智能辅助压缩感知(ACS)心脏电影(cine)序列在心功能评估中的应用价值.方法 本研究连续纳入2022年5月至12月在我院行心脏MRI检查的63例受检者.所有受检者均进行常规cine和ACS-cine两种序列扫描,采用5分法进行图像质量评价.应用Wilcoxon符号秩检验对2种心脏cine序列的扫描时间、图像质量评分及心室功能定量参数进行比较.采用Spearman相关分析和Bland-Altman 分析评价两种序列测量心室功能定量参数的相关性和一致性.结果 常规cine与ACS-cine序列扫描时间差异具有统计学意义(Z=-6.904,P＜0.001),后者可将扫描时间大幅缩短约92.82％.常规cine与ACS-cine序列图像质量评分差异无统计学意义(Z=-0.816,P＞0.05).在心功能定量参数评估方面,常规cine与ACS-cine序列之间的LVEF、LVESV、RVEF、RVEDV、RVESV参数差异无统计学意义(P均＞0.05),但LVEDV参数存在统计学差异(Z=-2.958,P＜0.05).常规cine与ACS-cine序列之间的心功能定量参数(LVEF、LVEDV、LVESV、RVEF、RVEDV、RVESV)均有良好的相关性(r=0.865～0.963,P均＜0.01).Bland-Altman分析显示,常规cine与ACS-cine序列图像获取的左心室及右心室功能定量参数(LVEF、LVEDV、LVESV、RVEF、RVEDV、RVESV)平均差异均接近于零,且变异范围很小,一致性高.结论 相较于常规cine序列,ACS-cine序列能显著缩短成像时间的同时保证图像质量,并可准确分析左心室及右心室功能定量参数,具有较高的临床应用价值.

Abstract

Objective To investigate the value of MRI artificial intelligence-assisted compressed sensing(ACS)cardiac cine(cine)sequence in cardiac function assessment.Methods Sixty-three subjects who underwent cardiac MRI in our hospital from May to December 2022 were consecutively included in this study.All subjects were scanned with both conventional cine and ACS-cine sequences,and image quality was evaluated using a 5-point scale.The Wilcoxon signed rank test was applied to compare the scan time,image quality scores and ventricular function results of the 2 cardiac cine sequences.Spearman correlation analysis and Bland-Altman analysis were used to evaluate the correlation and consistency of the two sequences for measuring cardiac function.Results The difference in scan time between the conventional cine and ACS-cine sequences was statistically significant(Z=-6.904,P＜0.001),with the latter significantly reducing scan time by approximately 92.82％.The difference in image quality scores between conventional cine and ACS-cine sequences was not statistically significant(Z=-0.816,P＞0.05).There was no statistically significant difference in LVEF,LVESV,RVEF,RVEDV,and RVESV parameters between conventional cine and ACS-cine sequences(all P＞0.05),but there was a statistically significant difference in the LVEDV parameter(Z=-2.958,P＜0.05).Quantitative cardiac function parameters(LVEF,LVEDV,LVESV,RVEF,RVEDV,RVESV)were all well correlated between conventional cine and ACS-cine sequences(r=0.865-0.963,all P＜0.01).Bland-Altman analysis showed that the mean differences in quantitative parameters of LV and RV function(LVEF,LVEDV,LVESV,RVEF,RVEDV,RVESV)obtained from conventional cine and ACS-cine sequence images were all close to zero with a small range of variation and high agreement.Conclusion Compared with conventional cine,ACS-cine can significantly shorten the imaging time while guaranteeing the image quality,and can accurately analyze the LV and RV functions,which has high clinical application value.
