【摘要】：目的研究磁共振彌散加權(quán)成像及ADC值在股骨頭壞死診斷及分期中的意義。方法收集股骨頭壞死患者64例作為實驗組,共80髖,男36例,女28例,年齡19-79歲,平均年齡44.3歲。病程2個月-17年不等。隨機(jī)選取健康志愿者40例,共80髖,男23例,女17例,年齡20-76歲,平均年齡51.4歲,作為對照組。全部研究對象均采用GE 1.5T掃描機(jī)進(jìn)行常規(guī)序列及DWI(b值取800 s/mm2)序列掃描,全方向彌散,獲得ADC圖,測得股骨頭感興趣區(qū)域ADC值,并對結(jié)果進(jìn)行統(tǒng)計學(xué)分析。結(jié)果DWI可以清晰顯示股骨頭壞死區(qū)域及正常股骨頭解剖結(jié)構(gòu)。股骨頭壞死區(qū)域ADC值為(7.01±1.41)×10-4mm2/s,其中只伴骨髓水腫組、只伴髖關(guān)節(jié)積液組、同時伴骨髓水腫和髖關(guān)節(jié)積液組、不伴骨髓水腫和髖關(guān)節(jié)積液組的股骨頭ADC值分別為(7.26±1.26)×10-4mm2/s、(7.43±1.05)×10-4mm2/s、(7.63±0.77)×10-4mm2/s、(4.75±0.82)×10-4mm2/s;正常人股骨頭ADC值為(2.94±0.76)×10-4mm2/s。結(jié)論MR DWI序列可以區(qū)分壞死股骨頭及正常人股骨頭;缺血壞死股骨頭ADC值明顯高于正常股骨頭ADC值;伴骨髓水腫和/或髖關(guān)節(jié)積液的壞死股骨頭ADC值增高;ADC值對于股骨頭壞死的早期診斷及分期有一定價值。
[Abstract]:Objective to study the significance of magnetic resonance diffusion weighted imaging and ADC value in the diagnosis and staging of femoral head necrosis. Methods 64 cases of femoral head necrosis were collected as experimental group, including 80 hips, 36 men, 28 women, 19-79 years old and 44.3 years old. The course of disease was 2 months -17 years. 40 cases of healthy volunteers were randomly selected, 80 hips, 23 men, 17 cases, year. The age of 20-76 years, the average age of 51.4 years old, as the control group, all the subjects were used GE 1.5T scanner for routine sequence and DWI (b value 800 s/mm2) sequence scanning, the whole direction was dispersed, the ADC map was obtained, the ADC value in the region of interest of the femoral head was measured, and the results were statistically analyzed. Results DWI can clearly show the area of avascular necrosis of the femoral head and the result of DWI. Normal femoral head anatomy. The ADC value of femoral head necrosis was (7.01 + 1.41) x 10-4mm2/s, with only bone marrow edema group, only with hip joint effusion group, combined with bone marrow edema and hip joint effusion group, without bone marrow edema and hip joint effusion, the ADC value of the femoral head was (7.26 + 1.26) x 10-4mm2/s, (7.43 + 1.05) x 10-4mm2/s, (7.63 +). 0.77) x 10-4mm2/s, (4.75 + 0.82) x 10-4mm2/s; normal human femoral head ADC value of (2.94 + 0.76) x 10-4mm2/s. conclusion MR DWI sequence can distinguish the femoral head and normal human femoral head; ischemic necrosis of femoral head ADC value is significantly higher than the normal femoral head ADC value; with bone marrow edema and / or hip joint accumulation of necrotic femoral head ADC value; ADC value of the value; ADC value It is valuable for early diagnosis and staging of femoral head necrosis.
