Review demonstrates noninvasive molecular and imaging diagnostics for detecting kidney transplant rejection, suggesting artificial intelligence integration can replace traditional invasive biopsies.

Key Points

To evaluate advances in noninvasive diagnostics, including liquid biopsy and functional imaging, for early and accurate detection of kidney allograft rejection.
Synthesized literature on molecular liquid biopsy biomarkers, including donor-derived cell-free DNA (dd-cfDNA) and urinary chemokines CXCL9 and CXCL10.
Reviewed functional imaging technologies such as ultrasound elastography and multiparametric magnetic resonance imaging (MRI) for graft assessment.
Examined artificial intelligence applications for multimodal integration to construct digital pathology and virtual biopsy frameworks.
Liquid biopsy biomarkers identify graft injury and immune activation in real time before overt structural or histological damage occurs.
Functional imaging modalities provide noninvasive macroscopic quantification of graft stiffness, tissue perfusion, and oxygenation levels.
Multimodal integration powered by artificial intelligence enables risk stratification and tiered diagnostic frameworks that reduce reliance on invasive needle biopsies.
