中文摘要:

目的：采用磁共振（MRI）超短回波时间序列（UTE）评估冈上肌腱的病变程度，探讨UTE序列在游泳运动员冈上肌腱腱病中的诊断价值。方法：纳入2016年3月-2017年2月于复旦大学附属华山医院运动医学科就诊的肩痛游泳运动员共10名（病变组），并招募健康志愿者10名（对照组）。对所有受试者肩关节行MRI常规序列和UTE序列，对冈上肌腱病变进行分级，测量UTE-T2*值后做两组间的比较及病变组内不同分级病例间的比较。结果：所有受检者的常规MRI图像均无明显的肩袖撕裂征象。磁共振常规序列显示对照组中0级4例，1级6例；而病变组中0级3例，1级7例，两组之间结果没有显著差异（P＞0.05）。磁共振UTE序列结果显示病变组冈上肌腱整体区域及止点区域T2*值均显著高于对照组（P＜0.05）；病变组0级病例止点区域T2*值与1级病例之间没有显著差异（P＞0.05）。结论：UTE序列能够定量评估冈上肌腱情况，这有助于游泳运动员肩关节疼痛的早期发现与准确诊断。

英文摘要:

Using magnetic resonance ultrashort echo time (UTE) sequence to evaluate the severity of supraspinatus tendon lesion and to analyze the diagnostic value of UTE sequence in supraspinatus tendinopathy of swimmers. Method: Ten swimmers with shoulder pain (disease group) and ten healthy volunteers (control group) were recruited in this study and they underwent an MRI scan with conventional and UTE sequences. According to conventional sequence, the supraspinatus tendon lesion was classified. The UTE-T2* value of ROI in supraspinatus tendon were calculated, and the difference of which was compared between the two groups and between the different graded cases within the disease group. Result: All the subjects had no signs of rotator cuff tears on conventional magnetic resonance imaging. The magnetic resonance conventional sequence showed 4 cases of grade 0 and 6 cases of grade 1 in the control group, and 3 cases of grade 0, 7 cases of grade 1 in the disease group. There was no significant difference between the results of the two groups (P> 0.05). The UTE T2* value in the whole region and the insertional region of the supraspinatus tendon of the diseased group was significantly higher than that in the control group (P < 0.05). There was no significant difference between the T2* value of insertional region of grade 0 and that of grade 1 in the diseased group (P>0.05).
