Implications of Biological and Procedural Factors of 18-f FDG Uptake by Normal Organs and Neoplastic Lesions

Implications of Biological and Procedural Factors of 18-f FDG PET/CT Uptake by Normal Organs and Neoplastic Lesions

To evaluate implications of biological and procedural factors of 18-f FDG PET/CT uptake on normal organs and neoplastic lesions.

18-f FDG is used on oncological patients undergoing PET/CT study at our nuclear medicine unit , its uptake by the tissues depends on glucose blood level and consumption then we evaluate the implications of biological and procedural factors on the uptake by normal organs and neoplastic lesions using standardized uptake values SUVmax , mean and peak.

Inclusion Criteria:

• cancer patients referred to nuclear medicine unit

Exclusion Criteria:

• patients with increased FDG uptake associated with non malignant causes such as diffuse bone marrow FDG uptake or lung infection or patients with extensive metastasis in target organs
