The portal hypertension of hepatic cirrhosis was studied by 99mTc-MIBI trans-rectum imaging. The portal systemic circulation was evaluated by the heart-liver ratio （H/L ratio） and the portosystemic shunt index （SI）. The H/L and SI in 12 normal cases were 0.145 ± 0.042 and 0.124 ± 0.029. Whereas in 18 patients with hepatobiliary diseases of non-cirrhosis were 0.207 ± 0.076 and 0.169 ± 0.051

and in 47patients with hepatic cirrhosis were 0.751± 0.313 and 0.422± 0.075. The results showed significant difference （P<0.01） between normal controls and non-cirrhosis group

and significant difference （P<0.001） between hepatic cirrhosis group andnormal controls

non-cirrhosis group. A significant difference （P<0.05） in child-pugh’s classification A

B and C group was also found. A significant correlation （r=0.95

P<0.01） with the H/L

SI and portal pressure measurementduring operation was found. If H/L>0.30

and SI≥0.22 were taken as positive criteria for diagnosis of portal hypertension with hepetic cirrhosis

the sensitivity

specificity and accuracy were 96%

90% and 94% respectively.Therefore

it was a new method for the diagnosis of portal hypertension with hepatic cirrhosis.
