【摘要】：目的：探讨质子加权预饱和脂肪抑制(PDWI-FS)在四肢关节外伤性骨髓水肿中的诊断价值。方法：62例四肢关节外伤患者在伤后30天内行多序列高场强(Siemens1.5T)磁共振检查,检查序列包括快速自旋回波(SE)T1WI、T2WI及PDWI-FS等。受伤部位为膝关节42例,髋关节6例,肘关节4例,肩关节6例,踝关节4例。结果：62例关节患者中MR检查发现骨髓水肿征象55例93处。外伤性骨髓水肿MR信号主要表现为T1WI、T2WI呈片状、不规则低或稍低信号影,T2WI在片状不规则地图样低或稍低信号影中夹杂线点状高信号影；PDWI-FS呈更明显片状、地图状不规则高信号影,在PDWI-FS序列更易识别。PDWI-FS与T1WI和T2WI比较差异均有统计学意义(P0.001,Uc=8.9；P0.001,Uc=15.4)。结论：MRI能早期诊断外伤性骨髓水肿,MR检查的PDWI-FS序列是目前确诊外伤性骨髓水肿的最优序列,在骨关节创伤MR检查中,应作为的常规序列使用。
[Abstract]:Objective: to investigate the diagnostic value of proton weighted presaturated fat suppressor PDWI-FSin traumatic bone marrow edema in extremities.Methods within 30 days after injury, 62 cases of limb joint trauma were examined by multisequence high field intensity Mr imaging (MRI), including fast spin echo (SET) T 1WI T 2WI and PDWI-FS, etc.There were 42 cases of knee joint, 6 cases of hip joint, 4 cases of elbow joint, 6 cases of shoulder joint and 4 cases of ankle joint.Results among 62 cases of arthrosis, 55 cases (93 sites) showed bone marrow edema by Mr examination.The main Mr signals of traumatic bone marrow edema were as follows: T1WIMr T2WI, irregular low or slightly low signal intensity T2WI in irregular map with low or slightly low signal intensity, and PDWI-FS showed more obvious flake and irregular hyperintense image.The difference between PDWI-FS and T1WI and T2WI was statistically significant when PDWI-FS sequence was easier to identify.Conclusion the PDWI-FS sequence for early diagnosis of traumatic bone marrow edema is the best sequence for the diagnosis of traumatic bone marrow edema. It should be used as a routine sequence in bone and joint trauma Mr examination.
