【摘要】:目的:探討鼻咽黏膜DWI分型對于診斷鼻咽惡性病變的價值。方法:根據(jù)鼻咽黏膜顯示的對稱性、黏膜最高信號與脊髓信號的比較,91例鼻咽黏膜DWI圖像分為4型,Ⅰ型(低信號對稱型)15例、Ⅱ型(低信號不對稱型)5例、Ⅲ型(高信號對稱型)32例、Ⅳ型(高信號不對稱型)39例。將分型結(jié)果與定性結(jié)果進(jìn)行比較,探討各型表現(xiàn)與鼻咽惡性病變發(fā)生的關(guān)系。結(jié)果:Ⅰ型中未發(fā)現(xiàn)惡性病變,Ⅱ型發(fā)現(xiàn)1例惡性病變,Ⅰ型與Ⅱ型之間無顯著性差異,合并為"Ⅰ型+Ⅱ型"。Ⅲ型發(fā)現(xiàn)惡性病變21例、Ⅳ型發(fā)現(xiàn)37例。整體上各型之間有顯著性差異(χ2=46.848,P0.001)。"Ⅰ型+Ⅱ型"與Ⅲ型、"Ⅰ型+Ⅱ型"與Ⅳ型、Ⅲ型與Ⅳ型之間均存在顯著性差異(χ2=18.533,P0.001;χ2=46.579,P0.001;χ2=10.052,P=0.002)。結(jié)論:當(dāng)DWI圖像上鼻咽黏膜表現(xiàn)為Ⅲ型或Ⅳ型時,臨床應(yīng)高度懷疑惡性病變的可能;若表現(xiàn)為Ⅰ型或Ⅱ型時,臨床上不應(yīng)盲目診斷為惡性,需充分結(jié)合其他輔助資料分析。
