【摘要】:目的:探討骨密度值與骨質疏松椎體壓縮性骨折MRI STIR黑色線性信號的出現是否有關聯以便更好為臨床治療提供參考。方法:研究收集自2014-07-01至2016-07-31在廣西中醫(yī)藥大學第一附屬醫(yī)院脊柱外科住院患者。對符合納入標準的574名患者,按照腰椎QCT分為A組:腰椎CTQ≤30mg/cm~3;B組:30mg/cm~3腰QCT值≤50mg/cm~3;C組:50mg/cm~3腰QCT值80mg/cm~3;D組:80mg/cm~3≤腰QCT值120mg/cm~3。其中,A組142例,B組172例,C組177例,D組83例。調閱每組的MRI資料,記錄其在STIR脂肪抑制像上出現黑色線性信號的有無。運用SPSS22統(tǒng)計軟件進行數據分析和處理,性別、不同骨密度組之間黑色線性信號的有或無用卡方檢驗,檢驗水準α設定為0.05,其中P0.05表示差異具有顯著性。而各組MRI STIR上黑色線性信號的有無在卡方檢驗兩兩對比時,應根據Bonferroni法下調檢驗水準α':α/比較次數=0.05/6=0.008,其中P0.008,表示差異具有顯著性。年齡符合正態(tài)分布及方差齊性檢驗用方差分析,不符合正態(tài)分布及差齊性的采用非參數Kruskal-Wallis檢驗,檢驗水準α設定為0.05,其中P0.05表示差異具有顯著性結果:四組間性別、年齡分布比較無顯著性,組間具有可比性。四組間MRI STIR有無黑色線性信號經皮爾森(Pearson)卡方檢驗得出:X~2=16.467a,df=3,P=0.001,P0.05,差異具有顯著性,而兩兩比較中,A與B、A與C、A與D相比,P0.008差異具有顯著性,而B與C、B與D、C與D相比時,P0.008,差異無顯著性,且A組黑色線性信號所占的比率為54.2%,在四組中最高。結論:MRI作為早期診斷骨質疏松性骨折的首選方法,在早期診斷時通過MRI STIR脂肪抑制像上“黑色線性信號”預測骨折預后,本研究發(fā)現骨密度值大小可能與MRI STIR脂肪抑制像上黑色線性信號有關聯。特別是當骨密度腰QCT值≤30mg/cm~3時,其出現黑色線性信號的機率越大。
