Lesion identified prospectively on PET/CT but only retrospectively on PET/MRI.

Abstract

<p>65 year-old male with bladder cancer who underwent PET/CT for subsequent treatment strategy. (A) PET/CT image (upper: PET image from PET/CT, lower: fused PET and CT) (B) PET/MRI image (upper: PET image from PET/MRI, lower: fused PET and MRI). PET/CT could identify the small nodular lesion at the left pelvic wall, due primarily to the better spatial localization possible with CT in this case. It was identified on PET/MRI only retrospectively, as on the initial read, it was thought to be activity in adjacent bowel.</p
