磁共振与磁共振关节造影在检测无既往肩部手术史的患者肩袖肌腱撕裂中的比较。
MR versus MR arthrography in detection of supraspinatus tendon tears in patients without previous shoulder surgery.

Skeletal Radiol. 2014 Jan;43(1):43-8. doi: 10.1007/s00256-013-1745-x.
PURPOSE
We report the prevalence of supraspinatus tendon tears seen on MR arthrography that are not seen on conventional MR exam in the same patient population.
MATERIALS AND METHODS
A total of 150 consecutive conventional shoulder MR and MR arthrography exams performed on the same patients who went on to arthroscopy were reviewed retrospectively by consensus reading of two musculoskeletal radiologists. Full-thickness supraspinatus tendon tears were assessed. None of the patients had previous shoulder surgery.
RESULTS
There were 113 full-thickness supraspinatus tendon tears seen on conventional MR exam while there were 119 full-thickness supraspinatus tendon tears seen on MR arthrography. The six additional full-thickness supraspinatus tendon tears seen on MR arthrography but not seen on conventional MR exam were confirmed at arthroscopy.
CONCLUSIONS
Some full-thickness supraspinatus tendon tears are not seen on conventional MR exam but are seen on MR arthrography. This is most likely due to fibrosis at the supraspinatus tendon tear site simulating an intact tendon on conventional MR.
目的
我们报告了在同一位患者人群中，磁共振关节造影术（MR Arthrography）上可见但常规磁共振检查（MR）上不可见的冈上肌腱撕裂的发生率。
材料与方法
回顾性分析了 150 例连续进行的常规肩关节 MR 和 MR 关节造影术检查，这些患者随后进行了关节镜检查。由两名肌肉骨骼放射科医生进行共识阅读，评估全层冈上肌腱撕裂。所有患者均无既往肩部手术史。
结果
在常规 MR 检查上共发现 113 例全层冈上肌腱撕裂，而在 MR 关节造影术上共发现 119 例全层冈上肌腱撕裂。在 MR 关节造影术上发现了 6 例常规 MR 检查上未发现的全层冈上肌腱撕裂，这些撕裂在关节镜下得到了证实。
结论
有些全层冈上肌腱撕裂在常规 MR 检查上不可见，但在 MR 关节造影术上可见。这很可能是由于冈上肌腱撕裂部位的纤维化模拟了常规 MR 上的完整肌腱。
