| Outline of Final Research Achievements |
If the contrast medium can be injected from the fine needle at an injection pressure lower than the pressure that causes damage (dehiscence) of the parenchymal organ, it is possible to visualize the intra-organ vessel with less parenchymal damage. The probability of parenchymal dehiscence caused by injection at a fixed pressure (30, 40, 50, 60, 70, 80, 90 mmHg) of pig liver is 0%, 7%, 16%, 37%, 40%, 100%, 70%, respectively. Therefore, it was considered that the parenchymal dehiscence to the porcine liver occurred at an injection pressure of 40 mmHg or higher, and that bile ducts, portal veins, etc. could be visualized without causing parenchymal dehiscence at an injection pressure of 30 mmHg. The frequency of parenchymal dehiscence at fixed pressure was also observed in the spleen and kidney, and it was found that if the injection pressures were set to 40 mmHg and 50 mmHg or less, respectively, parenchymal damage was unlikely to occur.
