Transplant renal artery stenosis(TRAS) was frequently occurred among patients after renal transplantation. The main goal of this study was to evaluate the feasibility of inflow inversion recovery (IFIR) technique in the assessment of TRAS by using digital subtraction angiography(DSA) as a reference. We measured the stenosis degrees of transplant renal arteries with IFIR and DSA, respectively. We obtained a strong correlation between IFIR and DSA, and no significant difference was found between these two techniques. Therefore, IFIR can been demonstrated as a noninvasive, accurate and valuable method in the diagnosis and evaluation of TRAS.
