WCN24-1794 Correlation of renal histological changes with ultrasound parameters in transplant patients

Kidney transplant biopsies play a pivotal role in the diagnosis of allograft dysfunction, usually being preceded by renal ultrasound examination. Unlike native kidneys, cortical echogenicity in kidney grafts cannot be directly compared to liver or spleen echogenicity, so that echogenicity assessment relies mostly on corticomedullary differentiation, often in association with Doppler resistivity index calculation.
