在注射钆喷酸二葡胺前后，对 27 名患者和 6 名健康志愿者的 36 个颞下颌关节 (TMJ) 进行了磁共振 (MR) 成像。 12 个无症状关节作为对照，12 个颞下颌关节有症状的内部紊乱，12 个颞下颌关节有风湿性炎症。 1个无症状关节，4个关节内部紊乱，1个关节有风湿受累，可见少量或中度关节积液；在所有这些中，观察到积液的对比度增强。一侧风湿关节大量积液经过延迟成像后才得到增强。在健康对照和患有内部紊乱的患者中，没有看到或仅看到关节内组织的轻微增强。 12 例风湿性 TMJ 中的 11 例显示沿椎间盘和关节面（即通常没有滑膜的区域）的软组织中度或强烈增强。未强化的1个风湿关节骨性强直，关节间隙内无残留软组织。钆增强 TMJ 磁共振成像可以有效地描绘风湿性炎症性关节病的增殖滑膜。
Magnetic resonance (MR) imaging of 36 temporomandibular joints (TMJs) in 27 patients and six healthy volunteers was performed before and after injection of gadopentetate dimeglumine. Twelve asymptomatic joints were used as controls, 12 TMJs had symptomatic internal derangement, and 12 TMJs had rheumatic inflammatory disease. A small or moderate joint effusion was seen in one asymptomatic joint, four joints with internal derangement, and one joint with rheumatic involvement; in all of these, contrast enhancement of the effusion was observed. A large effusion in one rheumatic joint was enhanced only after delayed imaging. In healthy controls and patients with internal derangement, no or only minimal enhancement of intraarticular tissues was seen. Eleven of the 12 rheumatic TMJs showed moderate or intense soft-tissue enhancement along the disk and articular surfaces (ie, in areas normally devoid of synovial membrane). The one rheumatic joint without enhancement had bony ankylosis and no remaining soft tissue within the joint space. Gadolinium-enhanced MR imaging of the TMJ may effectively depict the proliferating synovium of rheumatic inflammatory joint disease.
