Overview

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

Detailed description

-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.

Interventions

  • Device PET/CT with 18-FDG
    * 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 outcome measures

  • -To measure SUVs by using different correction methods in oncological PET/CT imaging. [Time frame: 1/12/2025 to 1/10/2027]
Secondary outcome measures (1)
  • To determine if SUVbsa is more accurate than SUVbw in obese patients. [Time frame: 1/12/2025 to 1/10/2027]

Eligibility criteria

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.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
