Brief Summary:
The investigators wish to determine if standard and digital PET/CT scanners provide equivalent results for disease detection and diagnosis.

Condition or disease Intervention/treatment Phase
Cancer Diagnostic Test: Digital PET/CT scan Phase 2 Phase 3

Detailed Description:
There will be a single injection of the PET radiopharmaceutical followed by a standard PET/CT scan and immediately after by the digital PET/CT scan, or vice versa. The investigators wish to determine if image quality is equivalent with the digital PET/CT scanner.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 270 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Comparison of Standard PET/CT vs. Digital PET/CT
Actual Study Start Date : March 29, 2017
Estimated Primary Completion Date : April 1, 2020
Estimated Study Completion Date : April 1, 2021

Arm Intervention/treatment
Patients undergoing digital PET/CT
Single arm prospective study of paired imaging studies. Patients who are referred to Nuclear Medicine and are scheduled to undergo imaging on the standard PET/CT will also have imaging performed on the digital PET/CT.
Diagnostic Test: Digital PET/CT scan
The Division of Nuclear Medicine and Molecular Imaging at Stanford has installed the first ever GE-made digital PET/CT scanner worldwide. The investigators wish to determine if the digital PET/CT scanner offers equivalent image quality as the standard PET/CT scanner.

Primary Outcome Measures :
  1. Diagnostic image quality [ Time Frame: an expected average of 3 hours ]

    Diagnostic image quality will be determined using a 5-point Likert Scale that reads:

    5 - Diagnostic: Excellent diagnostic image quality;

    4 - Diagnostic: Good diagnostic image quality;

    3 - Diagnostic: Acceptable diagnostic image quality;

    2 - Sub-optimal diagnostic: image quality with limited additional clinical information;

    1 - Non-diagnostic: non-diagnostic image quality
