Vendor: GE 3T HDxt 16.0. Field strength 3 T. Type of coil (number of channels): HD TORSO ARRAY 8 CH. No endorectal coil. For DCE: concentration of gadolinium (use 0.1 mmol/kg) MultiHance (gadobenate dimeglumine); rate of power injection 3 ml/s/volume based on weight of patient; volume of saline flush 3 ml/s/20 ml saline flush; injection and scan delay: imaging begins/acquired immediately. After 22 s of imaging, gadolinium is injected (22-s contrast injection scan delay); time per phase 8 s per phase/total scan time 04:33; number of phases 35
