This study examined the relationship between aminotransferase and DITI in the diagnosis of Liver Qi stagnation. An analysis was performed on the thermographic findings of 17 subjects with abnormally high aminotransferase value and 26 with no problem in blood sample at the Kangnam Korean Hospital, KyungHee University, Seoul, Korea, from March 2003 to May 2003. The body temperature was assessed by DITI thermographic measurements were performed on Rt. and Lt. subcostal area. Value of ${delta}T$ and absolute value of ${delta}T$ were tested by Mann-whitney U test. The absolute value of ${delta}T$ was statistically significant(P<0.00). The ${delta}T$ was also significant(P<0.01) and the temperature of Rt. area was higher than that of Lt. area. It is believed that DITI may be a favorable alternative to the diagnosis of Liver Qi stagnation.
