The early diagnosis of liver cirrhosis based on CT imaging by auto-recognition technique

KONG Ping,SU Shibing,YAN Guangle.Department of Management,Shanghai University for Science and Technology,Shanghai 200093,China  
Objective An auto-recognition system for measurement of liver proportion in computerized tomography imaging was developed for early diagnosis of hepatitis B-related liver cirrhosis.Methods The right and left liver proportion in CT imaging in patient with hepatitis B was measured and an formula was established in the database.Results The difference of L1/L2 and R1/L1 ratio between patients with liver cirrhosis and with chronic hepatitis B was significant(p 0.05);we got a formula of D=1.650 L1/L2+0.509 R1/L1-5.019 and the cut-off value was 0.0795;when D0.0795,the liver cirrhosis was diagnosed,while D0.0795,the chronic hepatitis B was considered.The accuracy of cirrhosis diagnosis was 68.42%,and of the exclusion was 89.8%.Conclusion We may use the auto-recognition system in CT-imaging to predict or diagnose the early liver cirrhosis.
