只有在组织血管丰富，有许多薄壁扩张的血管，或血管异常渗透和扩张的情况下，如急性炎症，才有可能进入血管。在这些情况下，少数Thorotrast颗粒可能进入某些血管，但由于其含有大量红细胞，通常很容易识别这些血管。当追踪它们的连接时，就像在注射材料的连续切片中很容易做的那样，它们被发现是血管的分支。要在肠的某个部位注射淋巴管，必须将针头插入粘膜，在那里可以找到最细的毛细淋巴管丛。通常，注射到肠的肌肉层是不成功的。
likely to enter the blood-vessels only in those cases where the tissue is exceedingly vascular, with many thin-walled dilated blood-vessels, or where the blood-vessels are abnormally permeable and dilated, as in acute inflammation. In these instances a few granules of thorotrast may enter some of the blood-vessels, but it is usually easy to recognize such vessels because of their large red blood-cell content. When their connexions are traced, as can be readily done in serial sections of injected material, they are found to be branches of undoubted blood-vessels. To make injections of the lymphatics in a part of the bowel it is necessary to insert the needle into the mucous membrane where the plexus of finest lymphatic capillaries is to be found. Usually no success is to be obtained by injecting into the muscular layers of the bowel.
