摘要
对１２１个直径≤３ｃｍ的孤立肺结节（ＳＰＮ）（包括９７个恶性结节，２４个结核瘤）做了薄层ＣＴ、磁共振成像（ＭＲＩ）与病理的对照研究。在ＣＴ上，恶性结节的主要形态学特点是分叶、毛刺、血管连接、泡样征及空气支气管征；而结核瘤的主要形态学特点是边缘光滑、密度均匀、卫星灶及钙化。在２４个ＳＰＮ的ＭＲＴ＿２加权成像（Ｔ＿２ＷＩ）中，１３个恶性结节呈高信号，而全部４个结核瘤表现为中等信号，两者具有显著性差异。提示：ＭＲＩ与ＣＴ对于恶性结节与结核瘤的鉴别诊断具有互补性。
orrelative study of CT,MRI and pathology wasdone on121 cases with solitary pulmonary nodule lessthan 3 cm in diameter, including 97 malignant nedulesand 24 tuberculoma. On CT, the main morphologicalcharacteristics of the malignant nedules is lobucation,spiculation,vessele involvement,heterogeneousdensity,and vacuole sign and air bronchogram,andthat of the tuberculoma, the smooth margin,homoge-neous density,calcification. On the other hand,the rel-ative signal intensity of these pulmonary nodules were e-valuated on T_1、T_2 weighted image. Our preliminary re-sults indicated that though MRI is inferior to CT in theassessment of the margin and internal feature of thenedule,it can provide further information in differenti-ating between malignant nedule and tuberculoma.
