| الوصف: | Cerebral perfusion computed tomography (CT) has been widespread, but abdominal perfusion CT has not been very popular because there has been a problem with regard to the limit of irradiation range and respiratory effects. Recently, it became easy to perform perfusion of abdominal organs because the use of multi detector row CT (MDCT) has been extensive. Along with it, the number of hospitals that perform liver perfusion CT has increased. However, patient dose of the liver perfusion CT is very high, making it very important to reduce patient dose. We created the virtual data that reduced the number of irradiation by partly reducing the data obtained on the liver perfusion CT. We compared the analysis results of all data with that of the partly reduced. It is possible to reduce the patient dose by reducing the number of irradiation because there was no significant difference in the analysis results. |
