【摘要】:目的:探讨鼻咽黏膜DWI分型对于诊断鼻咽恶性病变的价值。方法:根据鼻咽黏膜显示的对称性、黏膜最高信号与脊髓信号的比较,91例鼻咽黏膜DWI图像分为4型,Ⅰ型(低信号对称型)15例、Ⅱ型(低信号不对称型)5例、Ⅲ型(高信号对称型)32例、Ⅳ型(高信号不对称型)39例。将分型结果与定性结果进行比较,探讨各型表现与鼻咽恶性病变发生的关系。结果:Ⅰ型中未发现恶性病变,Ⅱ型发现1例恶性病变,Ⅰ型与Ⅱ型之间无显著性差异,合并为"Ⅰ型+Ⅱ型"。Ⅲ型发现恶性病变21例、Ⅳ型发现37例。整体上各型之间有显著性差异(χ2=46.848,P0.001)。"Ⅰ型+Ⅱ型"与Ⅲ型、"Ⅰ型+Ⅱ型"与Ⅳ型、Ⅲ型与Ⅳ型之间均存在显著性差异(χ2=18.533,P0.001;χ2=46.579,P0.001;χ2=10.052,P=0.002)。结论:当DWI图像上鼻咽黏膜表现为Ⅲ型或Ⅳ型时,临床应高度怀疑恶性病变的可能;若表现为Ⅰ型或Ⅱ型时,临床上不应盲目诊断为恶性,需充分结合其他辅助资料分析。
