Abstract |
Authors classified 161 cases of photon defects due to
the gall bladder on hepatic parenchymal scintigraphy on
Tc-99m-phytate and Tc-99m-DISIDA according to the
position of the gall bladder, the pattern of photon
defects and the hepatobiliary diseases. The results
were as follows; 1) Conocordance of Tc-99m-DISIDA and
Tc-99m-phytate hepatic parenchymal images in photon
defect due to the gall bladder was 94% of 32 cases. 2)
The frequency according to the position of the gall
bladder was in order to 68% of the gall bladder of the
lower margin of the liver, 30% of the intrahepatic gall
bladder and 2% of the extrahepatic gall bladder, and
the frequency of the photon defects due to the gall
bladder was in order to 81% of the intrahepatic gall
bladder, 71% of the gall bladder of the lower margin of
the liver and 20% of the extrahepatic gall bladder. 3)
The pattern of the photon defects due to the gall
bladder was 47% of funnel shape in the intrahepatic
gall bladder, 69% of semilunar shape in the gall
bladder of the lower margin of the liver and 100% of
semilunar shape in the extrahepatic gall bladder. 4)
All of 9 cases of the intrahepatic gall bladder at the
lateral area of the right lobe and the gall bladder of
the lower margin of the liver at the right hepatic
angle were associated with liver cirrhosis with the
right lobe atrophy and the left lobe hypertrophy, 2
cases of the gall bladder of the lower margin of the
liver at just-left side of the porta hepatis with
hepatoma in the right lobe and 1 case of the
intrahepatic gall bladder at the central portion of the
right lobe with choledochal cyst. |
