目的
我们的目标是研究序列动态对比增强SPGR MRI在颞下颌关节（TMJ）疼痛患者非手术随访中的作用。
方法
10例（10个关节）颞下颌关节内紊乱的患者进行了T1加权SE和系列后钆SPGR MR脉冲序列成像。
结果
在治疗前的T1加权像上，一个关节的椎间盘位置正常，九个关节的椎间盘向前移位而没有复位。治疗后，椎间盘在一个关节中保持正常位置，在八个关节中向前移位而不复位，在一个关节中向前移位而复位。治疗后的动态研究显示，10个关节中有7个关节的后盘附着的对比增强降低。这7例患者的关节疼痛消退或减轻。
结论
这些结果表明，椎间盘后部附着的对比度增强降低与关节疼痛的缓解或减轻之间存在相关性。这种相关性比临床表现与椎间盘解剖结构之间的相关性强得多。
PURPOSE
Our goal was to investigate the role of serial dynamic contrast-enhanced SPGR MRI in the nonsurgical follow-up of patients with temporomandibular joint (TMJ) pain.
METHOD
Ten patients (10 joints) with internal derangement of the TMJ were imaged with T1-weighted SE and serial postgadolinium SPGR MR pulse sequences.
RESULTS
On T1-weighted images prior to treatment, the disk position was normal in one joint and anteriorly displaced without reduction in nine joints. After treatment, the disk remained normally positioned in one joint, was anteriorly displaced without reduction in eight joints, and was anteriorly displaced with reduction in one joint. The dynamic study after treatment showed a decrease in contrast enhancement of the posterior disk attachment in 7 of 10 joints. These seven patients had resolution or reduction in joint pain.
CONCLUSION
These results suggest an association between a decrease in contrast enhancement of the posterior disk attachment and resolution or reduction in joint pain. This association was much stronger than the association between the clinical findings and the anatomy of the disk.
