About this study

-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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Cancer patients (> 18 years old) referred to nuclear medicine unit to do F18-FDG PET/CT study.

Exclusion criteria

Patients < 18 years old.
Patients with increased FDG uptake on tissue associated with non-malignant causes such as diffuse bone marrow FDG uptake or inflammatory.
Patients with extensive metastasis.

Treatment and study plan

PET/CT with 18-FDG

Device

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.

Primary outcomes

-To measure SUVs by using different correction methods in oncological PET/CT imaging.

Time frame: 1/12/2025 to 1/10/2027

-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.

Secondary outcomes

To determine if SUVbsa is more accurate than SUVbw in obese patients.

Time frame: 1/12/2025 to 1/10/2027

-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.
