本研究的目的是评价频率选择性脂肪饱和(FS)T2加权像(T2WI)在检测下颌骨髁突骨髓水肿中的应用价值。对200例TMJ相关疼痛患者行FST2WI和常规T1WI或常规T2WI和T1WI扫描，观察其骨髓异常的MR表现。研究的其他参数包括TMJ积液、关节盘移位类别和皮质骨异常。FS、T2W1和T1WI对骨髓水肿的显示率和面积均明显高于常规T2WI和T1WI。FS T2W I和T 1W I的骨髓异常与疼痛的相关性明显强于常规T 2W I和T 1W I。这项研究证实，FS T2WI可用于检测与TMJ相关疼痛相关的下颌骨髁状突的“水肿型”。
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 T2Wl 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.
