Doppler ultrasound for the evaluation of chronic renal allograft dysfunction

Key Points

Elevated resistance index (RI) of the renal artery correlates with chronic renal allograft dysfunction.
The enhanced diastolic velocity (EDV) of the segmental artery offers critical diagnostic support for kidney assessment.
Using both EDV and kidney length provides significant insights into pathological changes in renal function.
Assessment techniques may enable earlier detection and management of renal allograft dysfunction.

Abstract

Among the Doppler ultrasound parameters, the RI of the renal artery and the EDV of the segmental artery were the most useful in the diagnosis of CRAD. Further, the combination of the EDV of the segmental artery and kidney length showed significant potential in assessing pathological changes in CRAD.
