Phenotypic appearances of prostate utilizing PET-MRI and PET-CT with 68Ga-PSMA, radiolabelled choline and 68Ga-DOTATATE.

The objective of this study was to highlight the role of multimodality imaging and present the differential diagnosis of abnormal tracer accumulation in the prostate and periprostatic tissue. Our departments have performed molecular imaging of the prostate utilizing PET-CT and PET-MRI with a range of biomarkers including F-FDG, radiolabelled choline, Ga-DOTATATE PET-CT and Ga-PSMA images. We retrospectively reviewed the varying appearances of the prostate gland in different diseases and incidental findings in periprostatic region.

Estimated cumulative radiation dose from PET/CT in children with malignancies: a 5-year retrospective review.

Background: The increasing use of serial PET/CT scans in the management of pediatric malignancies raises the important consideration of radiation exposure in children.

Objective: To estimate the cumulative radiation dose from PET/CT studies to children with malignancy and to compare with the data in literature.

Materials And Methods: Two hundred forty-eight clinical PET/CT studies performed on 78 patients (50 boys/28 girls, 1.
