a-f In this patient, an additional lesion was detected at 20 min post-contrast injection. An adenoma in segment 6 is clearly visible at a 5, b 10 and c 20 min post-contrast injection. f An additional lesion was detected in segment 6 at 20 min post-contrast injection. In retrospective evaluation, with knowledge of the presence of this lesion at 20 min, a subtle hypointensity already reflects the presence of the lesion at d 5 and e 10 min
