A clinical study of using ROC to compare the efficiency of ASL and BOLD in diagnosis of renal allograft function.

ABSTRACT:

Background

This retrospective study aims to evaluate the effectiveness of renal transplantation function by comparing arterial spin labeling (ASL) and blood oxygen level dependent (BOLD) imaging with the receiver operating characteristic (ROC) curve.

Methods

According to the estimated glomerular filtration rate (eGFR) values, 42 patients with normal kidney grafts (the normal kidney graft group, eGFR <60 mL/min/1.73 m²) and 93 patients with injured grafts (the kidney graft injury group, eGFR <60 mL/min/1.73 m²) were included in the present study. Renal blood flow (RBF) and the effective transverse relaxation rate (R2*) were calculated by comparing ASL and BOLD imaging. The ROC curve and the youden index were used to evaluate the diagnostic performance of
