1、腰椎骨質(zhì)增生與椎間盤膨出或突出的相關(guān)性【摘要】目的探討腰椎骨質(zhì)增生與椎間盤膨出或突出的相關(guān)性，分析骨贅常見MRI信號類型。資料與方法回顧性分析行腰椎MRI檢查的202例患者的影像學(xué)資料，分別記錄腰椎有無骨贅形成、最長骨贅長度及信號、椎間盤膨出或突出程度，并分析所有患者及男性患者、女性患者各自最長骨贅長度與椎間盤膨出或突出程度之間的相關(guān)性。結(jié)果202例腰椎圖像包括1010個椎體，其中156個椎體有肉眼可見骨贅形成，MRI上骨贅主要表現(xiàn)為T1和T2等或高信號，STIR低信號，平均最長骨贅長度為(05.80士2.40~，平均椎間盤膨出或突出程度為(06.17士2.64)~，兩者呈顯著正相關(guān)(r
