前哨淋巴结活检（SLNB）对癌症的分期和治疗有很大的影响。本研究的目的是通过使用多探测器行计算机断层扫描（MDCT）构建三维图像来研究下肢的淋巴解剖结构。为了选择合适的造影剂在尸体MDCT淋巴成像，我们测试了四种造影剂注射到新鲜的猪肾。选择合适的造影剂后，对5具新鲜尸体的10条下肢进行了研究。注射造影剂后，用高空间分辨率MDCT扫描每只下肢。氧化锌混合物被认为是最合适的对比剂配方的MDCT成像的尸体解剖的CT值和无外渗。高分辨率MDCT成像显示腿部有两条不同的浅表淋巴通路。大隐静脉旁的一条淋巴通路有恒定的行程，并与腹股沟浅淋巴结相连。然而，另一条途径，沿着小隐静脉，是可变的。部分深淋巴管绕过腹股沟淋巴结。使用一种新的方案，我们能够在尸体模型中构建下肢动脉的三维图像。MDCT成像提供了关于下肢两种不同浅表淋巴通路的新信息。临床解剖学，2013.© 2013 Wiley Periodicals，Inc.
Sentinel lymph node biopsy (SLNB) has had a great impact on the staging and treatment of cancer. The purpose of this study was to study the lymphatic anatomy of the lower extremities by constructing three‐dimensional images using multi‐detector‐row computed tomography (MDCT). To select appropriate contrast media for MDCT lymphatic imaging in a cadaver, we tested four kinds of contrast media by injecting them into fresh swine kidneys. After the suitable contrast medium was selected, 10 lower extremities from 5 fresh cadavers were studied. After injection of the contrast medium, each lower extremity was scanned with high‐spatial‐resolution MDCT. The zinc oxide mixture was found to be the most appropriate contrast formula for MDCT imaging of cadaver lymphatics in terms of CT value and no extravasation. The high‐resolution MDCT imaging revealed two different superficial lymphatic pathways in the legs. One lymphatic pathway accompanying the great saphenous vein had a constant course and was connected to the superficial inguinal lymph nodes. However, another pathway, along the small saphenous vein, was variable. Some of the deep lymphatic vessels bypassed the inguinal lymph nodes. Using a new protocol, we were able to construct three‐dimensional images of the lower extremity lymphatics in a cadaver model. MDCT imaging provided novel information about two different superficial lymphatic pathways in the lower extremities. Clin. Anat., 2013. © 2013 Wiley Periodicals, Inc.
