-To measure SUVs by using different correction methods in oncological PET/CT imaging.
-To compare between SUV measurements in the tumor and liver using different standardizing parameters such as: body weight, lean body mass and body surface area.
Study Type
OBSERVATIONAL
Enrollment

* Patients will fast for at least 4 hrs before imaging with blood glucose level (\<200 mg/dl) before intravenous administration of F18-FDG. * Imaging will be performed approximately 45 to 60 min after 18F-FDG injection, an imaging field of view from the base of skull to mid-thighs with the arms above the head whenever possible is used or otherwise the arms are positioned beside the body.

Time frame: 1/12/2025 to 1/10/2027
To determine if SUVbsa is more accurate than SUVbw in obese patients.
-To determine if ''normalization of FDG uptake for the body surface area'' (SUVbsa) is independent of the patient's body size and is more reliable than SUVbw.
