Noninvasive test system of hepatic function

The conventional hepatic function tests have many deficiencies, such as large blood sampling, non-continuous and etc., so a new non-invasive test method is studied. The dye of indocyanine green (ICG) is intravenously injected. Afterward two spectrum signals of the hemoglobin and the ICG are picked w...

Summary:The conventional hepatic function tests have many deficiencies, such as large blood sampling, non-continuous and etc., so a new non-invasive test method is studied. The dye of indocyanine green (ICG) is intravenously injected. Afterward two spectrum signals of the hemoglobin and the ICG are picked with the signal acquire system. In lab-view software platform an algorithm is introduced to calculate the ICG concentration graph. Ultimately, the ICG plasma disappearance rate K, 15 minutes retention rate and other hepatic hemodynamic parameters which can mainly assess the hepatic function are deduced by means of analyzing the semi-logarithmic dye concentration graph.
