Fig. 5A. —35-year-old male potential donor whose preoperative MR angiogram was misinterpreted. Maximum-intensity-projection image obtained from MR angiogram (TR/TE, 5.0/2.0; flip angle, 20°) was initially interpreted as showing bilateral accessory renal arteries entering renal hila. However, at blinded retrospective analysis, this finding was seen to represent single renal arteries bilaterally (solid arrows) with early opacification of retroaortic component of circumaortic left renal vein (open arrows).
