It has been shown that intravenous administration of contrast media produces an MR arthrographic effect without the need for intraarticular injection. This is the first study evaluating this new technique of indirect MR arthrography in the diagnosis of glenoid labrum tears.
28 patients with clinically suspected labral injuries were prospectively investigated (1.5 Tesla, flexible surface coil). A plain MR examination of the shoulder (transverse and oblique-coronal orientation, T1-weighted spin- [TE/TR 15/675], proton density- and T2*-weighted gradient echo [TE/TR/Flip 14,32/600/30 degrees] sequences) and indirect MR arthrography (transverse and oblique-coronal orientation, fat-suppressed T1-weighted spin-echo sequences [TE/TR 15/675], intravenous injection of gadopentetate dimeglumine [0.1 mmol/kg], followed by 10-15 min of joint movement) were performed. Results were confirmed by arthroscopy and/or open surgery.
Indirect MR arthrography significantly improved delineation of the glenoid labrum and hyaline cartilage (p < 0.05). Sensitivity and specificity of indirect MR arthrography in the diagnosis of labral injuries were 90% and 89%, compared to 79% and 67% of the native MR examination.
Indirect MR arthrography is a promising non-invasive technique in the evaluation of the glenoid labrum.
已表明静脉注射造影剂可产生磁共振关节造影效果，而无需关节内注射。这是第一项评估这种间接磁共振关节造影新技术用于诊断盂唇撕裂的研究。
对28例临床怀疑有盂唇损伤的患者进行前瞻性研究（1.5特斯拉，柔性表面线圈）。对肩部进行常规磁共振检查（横断位和斜冠状位，T1加权自旋回波序列[TE/TR 15/675]、质子密度加权和T2*加权梯度回波序列[TE/TR/翻转角14,32/600/30度]）以及间接磁共振关节造影（横断位和斜冠状位，脂肪抑制T1加权自旋回波序列[TE/TR 15/675]，静脉注射钆喷酸葡胺[0.1 mmol/kg]，随后进行10 - 15分钟的关节活动）。结果通过关节镜检查和/或开放手术得以证实。
间接磁共振关节造影显著改善了盂唇和透明软骨的显示（p < 0.05）。间接磁共振关节造影诊断盂唇损伤的敏感性和特异性分别为90%和89%，而常规磁共振检查分别为79%和67%。
间接磁共振关节造影是评估盂唇的一种有前景的非侵入性技术。
