The objective of this study was to evaluate the utility of frequency-selective fat saturation (FS) T2-weighted images (T2WI) for the detection of bone marrow edema in the mandibular condyle. MR evidence of bone marrow abnormalities was examined on the set of FS T2WI and conventional T1WI or of conventional T2WI and T1WI in 200 patients with temporomandibular joint (TMJ) related pain. Other parameters studied were TMJ effusion, disk displacement categories, and cortical bone abnormalities. The detection rate and area of bone marrow edema by FS T2WI and T1WI were significantly greater than those assessed by conventional T2WI and T1WI. The correlation between bone marrow abnormalities on FS T2WI and T1WI and pain was significantly stronger than with conventional T2WI and T1WI. This study confirms that FS T2WI is useful for the detection of the "edema pattern" in the mandibular condylar associated with TMJ-related pain.
本研究的目的是评估频率选择性脂肪饱和(FS)T2加权成像(T2WI)在检测下颌髁突骨髓水肿中的效用。对200例患有颞下颌关节(TMJ)相关疼痛的患者,在FS T2WI以及传统T1WI或传统T2WI与T1WI上检查骨髓异常的磁共振成像(MR)证据。研究的其他参数包括TMJ积液、盘移位类别和皮质骨异常。FS T2WI和T1WI检测到的骨髓水肿发生率和面积显著大于传统T2WI和T1WI评估的结果。FS T2WI和T1WI上骨髓异常与疼痛之间的相关性显著强于传统T2WI和T1WI。本研究证实,FS T2WI有助于检测与TMJ相关疼痛有关的下颌髁突“水肿模式”。
