Computed Tomography and Radiographic Lymphography of the Thoracic Duct by Subcutaneous or Submucosal Injection

抄録

A simple method of lymphography of the thoracic duct was investigated. Using three female beagles, contrast media was administered rectally, vaginally and into the perianal tissue. The administration sites were gently massaged, and imaging was carried out at constant intervals using computed tomography and Radiograph. Moreover, Indian ink was administered into the rectum mucous membrane in dogs for the proof of this lymphography, and the lymph drainage routes were observed. The investigation showed that, clear computed tomography and radiograph contrast images of the thoracic duct were obtained by the injection of angiography contrast medium into subcutaneous and submucosa injection and 3D processing of these images revealed the three-dimensional positions and course of the thoracic duct and cisterna chyli.
