Research progress of functional magnetic resonance imaging and renal resistive index in evaluating contrast-induced nephropathy
With the development of medical imaging,contrast-induced nephropathy(CIN)caused by the widespread use of iodine contrast agents in CT enhanced examinations or angiography is one of the main causes of acute kidney injury.The potential nephrotoxicity of iodine contrast agents has been confirmed in clinical and experimental studies,but there is still a lack of effective prevention and treatment measures.Therefore,early detection of CIN can help clinical adjustments to treatment plans in a timely manner.Currently,scholars have conducted research on early detection of CIN,including imaging and biomarkers.Among them,functional magnetic resonance imaging(fMRI)and renal artery resistive index(RRI),as non-invasive medical imaging techniques,can clearly display the structure,function,and hemodynamic changes of the kidney,which has become an important research direction in the field of CIN risk detection.This paper provides a review of the application progress of fMRI and RRI in CIN and explores its potential application value.
