Under the guidance of magnetic resonance imaging, the mixture including motexafin gadolinium was delivered into the choledochus wall of swine. A T1 weighted sagittal image; B the needle pricked into the choledochus wall (arrow) where motexafin gadolinium was delivered; this was displayed as a high signal interpenetrating the choledochus (arrowheads). C, D Cross-sectional images of the choledochus before (C) and after injection (D). Reproduced from Zhang et al. [76]
