Abstract |
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. |
