The feasibility of 4D Flow in evaluating hemodynamic changes of transplant renal artery stenosis

Although 4D-Flow MRI is capable of detecting hemodynamic abnormalities, it is rarely employed in transplanted kidneys. Using 4D-Flow MRI, we assessed total volume, net flux, maximum flow, and mean flow rate and performed a statistical analysis of the correlation in this study. Total volume, net flux, maximum flow, and mean flow rate were shown to be inversely linked to the degree of stenosis in the transplanted renal artery. As a result, 4D-Flow MRI may be applied to study the hemodynamic changes of the transplanted renal artery noninvasively.
