Application of thermal tomography imaging in detection of liver injury / 国际生物医学工程杂志

ABSTRACT

Objective To compare and analyze the high risk factors of liver injury, and to explore the application of thermal texture maps (TTM) technology in the diagnosis and screening of liver injury. Methods A total of 3582 medical examiners were selected as subjects, and their general clinical data, the related physical and chemical test results and TTM results were collected. The relationship between TTM results and general clinical data and related physical and chemical results was statistically analyzed. The general clinical data and physical and chemical results of subjects with TTM negative and TTM positive liver injury were compared from the sample value statistics and the sample group comparison. Results The differences in the degree of liver damage and the main related indicators between the two groups were statistically significant (all P<0.05), except for the body mass and low-density lipoprotein cholesterol level. When using aminotransferase as the standard, the diagnostic sensitivity of TTM for liver injury was 93.18％, the specificity was 68.34％, the positive predictive value was 54.34％, and the negative predictive value was 90.32％. Conclusions TTM examination can not only reflect the state of liver injury, but also reflect the degree of injury. TTM is an important index and necessary supplement for evaluating liver injury.
