Hyperspectral imaging (HSI) with the KGnet model accurately predicts kidney transplant Delayed Graft Function (DGF) with 94% accuracy. This non-invasive approach enables early risk detection for improved patient outcomes.

Area of Science:

Transplant medicine
Medical imaging
Biochemistry

Background:

Delayed Graft Function (DGF) is a common complication after kidney transplantation (KT), impacting graft survival and patient prognosis.
Early and accurate identification of DGF is critical for optimizing post-transplant care and improving patient outcomes.

Purpose of the Study:

To develop and validate KGnet, a predictive model utilizing hyperspectral imaging (HSI) for early detection of DGF in kidney transplants.
To identify specific spectral signatures indicative of DGF risk before clinical manifestation.

Main Methods:

Analysis of 72 zero-hour kidney biopsy samples using hyperspectral imaging (HSI) across 400-1000 nm wavelengths.
Examination of spectral signatures related to tissue oxygenation, perfusion, and metabolic states.

Keywords:

Auxiliary diagnosis Delayed graft function Hyperspectral imaging Learning models Renal transplantation
