[Effectiveness of pharmacoangiography using nitroglycerin and angiotensin II]

An investigation of pharmacoangiography using a combination of nitroglycerin and angiotensin II demonstrated that it was useful due to the following reasons. First, good dilatation of the proximal portion of the arteries was demonstrated which enabled good clarity of the margin between the encasement and the normal portion of the arteries. Secondly, there was almost no change demonstrated in blood pressure immediately after administration. Thirdly, tumor vessels and intrapancreatic arteries were well recognized on the resulting images.
