Objective To explore the efficiency, cost, and time for examination of one‐stop‐shop gadoxetic acid disodium ( G d‐ EOB ‐ DTPA )‐enhanced magnetic resonance imaging ( MRI ) in preoperative evaluation for parent donors by comparing with multidetector computer tomography combined with conventional MR cholangiopancreatography ( MDCT ‐ MRCP ). Materials and methods Forty parent donors were evaluated with MDCT ‐ MRCP , and the other 40 sex‐, age‐, and weight‐matched donors with G d‐ EOB ‐ DTPA ‐enhanced MRI . Anatomical variations and graft volume determined by pre‐ and intra‐operative findings, costs and time for imaging were recorded. Image quality was ranked on a 4‐point scale and compared between both groups. Results G d‐ EOB ‐ DTPA ‐enhanced MRI provided better image quality than MDCT ‐ MRCP for the depiction of portal veins and bile ducts by both reviewers (p < 0.05), hepatic veins by one reviewer (p < 0.05), rather hepatic arteries by both reviewers (p < 0.01). Sixty‐nine living donors proceeded to liver donation with all anatomical findings accurately confirmed by intra‐operative findings. The “in‐room” time of G d‐ EOB ‐ DTPA ‐enhanced MRI was 12 min longer than MDCT ‐ MRCP . G d‐ EOB ‐ DTPA ‐enhanced MRI was cheaper than MDCT ‐ MRCP ( US $519.72 vs. US $631.85). Conclusion One‐stop‐shop G d‐ EOB ‐ DTPA ‐enhanced MRI has similar diagnostic accuracy as MDCT ‐ MRCP and can provide additional benefit in terms of costs and convenience in preoperative evaluation for parent donors.
