    Abstract:
    Hepatic arterial perfusion scintigraphy (HAPS) with 99mTc-macroaggregated albumin (MAA) was performed to reveal the effect of patients' posture for the arterial blood flow patterns in hepatic arterial infusion (HAI) chemotherapy. 20 patients of liver metastases with the percutaneously implanted catheter into the hepatic artery underwent HAPS following administration of 99mTc-MAA at the supine and the upright position under one week interval. 10 ml of the saline with radionuclide was injected at a rate of 1 ml per minute. Acquired two images at the different position of each patient were compared and grouped into three classes; similar, slightly different and different. Of 20 patients, 6 (30%) were judged as similar, 8 (40%) as slightly different, and 6 (30%) as different. These results suggest that the drug distribution can change by patients' posture in case of the slow rate HAI performed with continuous infusion pump.
