磁共振测量肩峰相关角度对SAIS的诊断价值

磁共振测量肩峰相关角度对SAIS的诊断价值摘要：目的：本研究旨在探讨磁共振测量肩峰相关角度对肩袖损伤的诊断价值。

方法：选取100例疑似肩袖损伤病人作为研究对象，进行MRI扫描，通过磁共振测量肩峰相关角度的数值来评估肩袖损伤情况，同时进行手术或随访确诊。

结果：研究结果显示，磁共振测量肩峰相关角度对肩袖损伤的诊断具有较高的准确性，其诊断准确率高达90%以上，并且在组织损伤方面具有相对较高的预测价值。

结论：磁共振测量肩峰相关角度是一种安全、准确、非侵入性的诊断方法，对于肩袖损伤的早期发现和定量化评估具有重要意义，可作为临床判断肩袖损伤的有力手段。
