摘　　要：目的:利用64层螺旋CT三维最大密度投影法重建显示SPN与其肺内血管关系进行分析并分型,探讨其对判断结节良恶性的诊断价值。方法:37例SPN患者,行64层螺旋CT增强扫描后行3D MIP重建观察结节与血管关系并分型。结果:37例3D MIP重建图像中,35例与血管关系显示良好,其中恶性22例,良性15例,表现为Ⅰ型表现的11例,恶性SPN10例,良性SPN1例;Ⅱ型表现为8例,恶性4例,良性4例;Ⅲ型表现为6例,全部为恶性SPN,Ⅳ型表现为6例,恶性1例,良性5例;Ⅴ型表现为4例,全部为良性SPN;表现为Ⅰ型和Ⅲ型血管关系的倾向于恶性,表现为Ⅳ型和Ⅴ型血管关系的结节倾向于良性,良恶性差异有统计学意义(P<0.05)。结论:64层螺旋CT增强扫描3D MIP重建可以准确显示SPN与血管的关系及其分型,对SPN良恶性的评价有重要价值。Objective：To investigate the relationship of solitary pulmonary nodule（SPN）with vascula r as well as its type by 64-slice spiral CT three-dimensions maximum-intensit y projection（3D MIP）reconstruction,the value of diagnosis was also studied. Methods：37 patients having SPN underwent 3D MIP reconstruction of vessels after enhanced 64-slice spiral CT.The type of vessels and the relation to SPN were analyzed. Results：37 images of 3D MIP reconstruction of vessels were clear in 35 patients,maligna nt 22 and benign 15.The SPN-vessels relationship was identified as 5 types,11 cases of type Ⅰ,malignant 10 cases and benign 1 case,8 cases of type Ⅱinclu ding malignant 4 cases and benign 4 cases,6 cases of type Ⅲ,all for malignant SPN,6 cases of type Ⅳ,1 case of malignant and 5 cases with benign pathology,4 cases of type Ⅴ,all for benign SPN;Malignant nodules most commonly showed typeⅠand typeⅢ,benign nodules often displayed type Ⅳ and type Ⅴ,there wer e significant difference between malignant cases and benign cases（P0.05）. Conclusion：64-slice spiral CT 3D MIP reconstruction after enhanced can clearly show the relationship of SPN with vascular appearance,which is important to dif ferentiate malignant nodules with benign ones.
