目的评价mDIXON-MRA对乳腺癌腋窝淋巴结是否可切除的临床诊断效能。方法采用回顾性病例-对照研究设计,收集2018年12月至2020年1月在重庆大学附属肿瘤医院影像科磁共振中心进行磁共振检查的乳腺癌患者77例,术前行腋窝区域的mDIXON-MRA、T... 目的评价mDIXON-MRA对乳腺癌腋窝淋巴结是否可切除的临床诊断效能。方法采用回顾性病例-对照研究设计,收集2018年12月至2020年1月在重庆大学附属肿瘤医院影像科磁共振中心进行磁共振检查的乳腺癌患者77例,术前行腋窝区域的mDIXON-MRA、T1WI、T2WI、T2WI(f/s)及T1WI-CE成像,并进行图像后处理重建,由两位放射科医师分别对所得图像根据医师阅片标准进行评估,通过判断淋巴结与周围血管的相互关系以评价淋巴结的可切除性,对比分析不同序列的评分差异。以乳腺科医师的术中判断为标准来绘制ROC(receiver operating characteristic)曲线,进而分析不同序列诊断乳腺癌患者肿大淋巴结能否切除的效能。结果 mDIXON-MRA、T1WI、T2WI、T2WI(f/s)、T1WI-CE组评分平均值分别为(2.01±0.97),(2.22±1.05),(2.22±1.07),(2.42±1.06)和(2.53±1.02),5组序列对于乳腺癌腋窝淋巴结的可切除性评估差异具有统计学意义(P<0.05),其中mDIXON-MRA组的曲线下面积(area under curve, AUC)最高为0.854,与多序列联合应用的AUC相当,评估效能最好。结论 mDIXON-MRA在多种磁共振序列中对评价乳腺癌腋窝淋巴结可切除性的临床诊断价值最高,其诊断效能与多序列联合应用相当。 展开更多

Soft tissue masses deep in the extremities pose significant challenges due to their potential involvement with adjacent major vessels,impacting treatment decisions and prognostication.While MRI is valuable in diagnosing these masses,specific signs for differential diagnosis are lacking.This study focuses on the utilization of mDixon magnetic resonance angiography(mDixon-MRA)combined with compressed sensing(CS)to assess the involvement of adjacent major blood vessels by soft tissue masses deep in the extremities.The methodology involves preoperative imaging evaluation,including conventional MRI and mdixon-MRA,intraoperative observation,and statistical analysis.The study suggests that combining mDixon-MRA with conventional MRI findings improves diagnostic efficacy.Combining mDixon-MRA with conventional MRI enhances diagnostic accuracy,offering clinicians a reliable method for assessing vascular involvement in soft tissue masses,thereby improving patient outcomes. 展开更多
