The purpose of this study was to assess the efficacy and feasibility of ultrasound (US)-guided magnetic resonance (MR) arthrography of the glenohumeral joint via a posterior approach.
Thirty-four patients (18 males and 16 females) who were suspected to have glenohumeral joint pathology were examined using MR arthrography. The patients ranged in age from 21 to 85 years, and the average age was 45±15.9 years. A Toshiba Xario US unit was utilized. Ultrasonography examinations were conducted using a broad-band 5-12 MHz linear array transducer. Gadolinium was injected into the shoulder joint using an 18-20 gauge needle. MR imaging was performed within the first 30 min after the injection.
The injection of gadolinium into the shoulder joint was successfully accomplished in all 34 patients. Major contrast media extravasation outside the joint was depicted in only two patients (5.9%). No major complications were encountered.
Ultrasonography is an effective alternate guidance technique for the injection of gadolinium into the glenohumeral joint for MR arthrography. US-guided arthrography via a posterior approach to the glenohumeral joint is safe, accurate, well tolerated by patients and easy to perform with minimal training.
本研究旨在评估经后路超声（US）引导下肩关节磁共振（MR）关节造影的有效性和可行性。
对34例疑似肩关节病变的患者（18例男性，16例女性）进行了MR关节造影检查。患者年龄在21至85岁之间，平均年龄为45±15.9岁。使用东芝Xario超声设备。超声检查采用5-12MHz宽带线性阵列探头。使用18-20号针头将钆喷酸葡胺注入肩关节。在注射后30分钟内进行MR成像。
34例患者均成功将钆喷酸葡胺注入肩关节。仅2例患者（5.9%）出现关节外造影剂大量外渗。未发生重大并发症。
超声是将钆喷酸葡胺注入肩关节进行MR关节造影的一种有效替代引导技术。经后路超声引导下肩关节造影安全、准确，患者耐受性良好，且只需极少培训即可轻松操作。
