摘要:
目的:探討MAGiC短時反轉恢復(short time in version recovery,STIR)序列磁共振掃描在骶髂關節(jié)炎骨髓水腫診斷中的應用價值。方法:納入95例強直性脊柱炎患者,分別采用T1WI、T2WI、T2加權脂肪抑制(T2 weight image fat suppression,T2WI FS)及MAGiC STIR序列進行骶髂關節(jié)斜冠狀面磁共振掃描。由2名放射科副主任醫(yī)師分別獨立分析掃描結果,將單側骶髂關節(jié)分為4個區(qū)域,采用國際脊柱關節(jié)炎評估協(xié)會制定的相關診斷標準診斷骨髓水腫,統(tǒng)計分析T2WI FS和MAGiC STIR序列診斷骶髂關節(jié)存在骨髓水腫區(qū)域的數量; 采用Hermann-Braun評分系統(tǒng)評價各區(qū)域的炎癥嚴重程度,統(tǒng)計分析這2種序列不同Hermann-Braun評分的區(qū)域數量; 并以T2WI FS序列診斷結果為標準,采用受試者操作特征曲線評價MAGiC STIR序列對骶髂關節(jié)炎骨髓水腫的診斷價值。結果:2名醫(yī)師對強直性脊柱炎患者骶髂關節(jié)各區(qū)域的炎癥嚴重程度的評價,一致性為優(yōu)(ICC=0.935,P=0.000)。T2WI FS序列和MAGiC STIR序列均診斷骨髓水腫患者60例,前者診斷存在骨髓水腫區(qū)域250個,后者診斷存在骨髓水腫區(qū)域230個,二者診斷存在骨髓水腫區(qū)域數量的比較,差異無統(tǒng)計學意義(χ2=1.218,P=0.270); 2種序列診斷結果中不同Hermann-Braun評分的區(qū)域數量的分布不同,差異有統(tǒng)計學意義(Z=-4.296,P=0.002)。MAGiC STIR序列診斷骶髂關節(jié)炎骨髓水腫的敏感度為86.92%、特異度為96.60%、陽性預測值為90.76%、陰性預測值為93.35%,MAGiC STIR序列診斷骶髂關節(jié)炎骨髓水腫的受試者操作特征曲線下面積為0.963(P=0.000)。結論:應用MAGiC STIR序列磁共振掃描診斷骶髂關節(jié)炎骨髓水腫具有較高的應用價值。
