摘要

傳統上評估顳顎關節障礙的方法包括X光片、關節攝影術及電腦斷層掃描。X光只能提供硬組織的變異，關節攝影術會使患者不舒服，而電腦斷層掃描之軟組織解析度較差，並且，以上的檢查方式皆會讓患者暴露於游離放射線的危險。顳顎關節核磁共振造影是一項新的檢查方式，它不僅能提供良好的軟組織解析度，而且檢查時能使患者免於暴露游離放射線的危險。本篇的報告主要是如何判讀正常及不正常的顳顎關節核磁共振造影影像，還有顳顎關節核磁共振造影與傳統X光、關節攝影術及電腦斷層掃描之比較。

Traditionally, evaluation of temporomandibular joint (TMJ) disorders includes plain film, arthrogram and CT scan. Plain film only reads bony abnormality, arthrogram makes patients discomfortable and the resolution of soft tissue image of CT scan is poor. The examinations mentioned above have the common disadvantage of making the patient exposed to harmful ionizing radiation. Recently the magnetic resonance imaging (MRI) of TMJ has been widely introduced. The MRI of the TMJ not only has the advantage of good resolution of soft tissue but also inflicts no ionizing radiation upon the patient. This article discusses how to interpret the normal and internal derangement of TMJ in MRI, and compares the MRI with plain film, arthrogram and CT scan in TMJ imaging.
