The Evaluation of Ischemia-reperfusion Injury in the Donor Liver Can Be Achieved Through the Utilization of Noninvasive Near-infrared Hyperspectral Imaging.

Hyperspectral imaging (HSI) is an advanced optical technology that combines spectroscopy and imaging, providing a non-destructive approach for clinical diagnosis. In recent years, hyperspectral imaging has emerged as a prominent research topic in the field of applied medicine. Liver transplantation is considered the most effective treatment for end-stage liver disease; however, the scarcity of donor livers and the growing number of patients awaiting transplantation pose significant challenges to global organ transplantation. The evaluation of donor livers has always been a focal point in liver transplantation. Currently, clinical evaluation relies heavily on subjective judgment by transplant physicians based on general appearance and touch assessments, along with clinical examinations and pathological biopsy results. Nevertheless, studies have demonstrated that these methods are not entirely reliable for assessing liver quality. Therefore, it is crucial to identify additional evaluation parameters and establish a convenient, reliable, and non-invasive method to assess donor liver quality. This study aims to analyze hyperspectral imaging data alongside clinical test data and recipient complications occurring between June 2022 to June 2024 to evaluate the quality of donor livers using hyperspectral imaging technology while exploring potential evaluation parameters.
