Radionuclide angiography of the liver and spleen with rapid bolus injection of 5 mCi of " Tc-Sn-phytate was performed for evaluation of dynamic flow change of the liver in 5 normal subjects and 11 patients with diffuse hepatocellular diseases. And quantification of hepatic arterial index (HAI) was generated from those TACs of the liver and compared with HAI generated from hepatic TAC with injection of " Tc-TcO, as previously reported method by former investigators. 67 patients with diffuse hepatocellular diseases undergoing hepatic scintigraphy were also evaluated by 2 minutes- hepatosplenic scintiangiography with 5 mCi of " Tc- phytate and followed injection of 7 mCi of ""Tc-TcO,. Those heaptic and splenic TACs were analysed and compared with HAIs of" Tc-phytate for evaluation of relative change {%> of count at 30 seconds and 1 minuite after peaks of rapid influx phase to the peaks (100%) in TACs of " Tc-phytate and at 1 minuite and 3 minuites after in 5 minuite-TAC of "Tc - TcO, .Correlation between HAIs with Tc-phytate and " Tc - Tc04 was highiy significant (R=0.984, P=O), and there was most significant and useful correlation (R=0.708, P<0.0001) between HAJ ad splenic TAC generated by Tc- phytate.
