Prognostic indicators estimated by 99mTc-GSA in acute liver damage

A negative value for R indicates non-survivals, and a positive value indicates survivals. The mortality rate was calculated as = 1/(1 + eR). The sensitivity was 0.909, specificity was 1.000, and accuracy was 0.978. The reliability of this formula was as good as that of another formula presented previously by the Intractable Liver Diseases Study Group of Japan. The use of 99mTc-GSA for estimating the prognosis of acute liver damage is useful, especially before the onset of hepatic encephalopathy.
