Abstract

The purpose of the second in the series of three review articles is to discuss the significance of changes in the retrodiscal tissue on MRI of the painful TMJ in patients with TMD. Decreased T1W or proton signal in the retrodiscal tissue is related neither to TMJ pain nor histologically clarified. However the increased MR signal, suggestive of higher vascularity, may reflect TMJ pain.

摘要

这三篇综述文章系列中的第二篇旨在探讨颞下颌关节紊乱病（TMD）患者疼痛性颞下颌关节（TMJ）的MRI上盘后组织变化的意义。盘后组织中T1加权像或质子信号降低与TMJ疼痛无关，在组织学上也未得到明确解释。然而，提示血管增多的MR信号增强可能反映TMJ疼痛。
