Which PET modality uses 4 dwell times during the day?

• A. Fast PET
• B. Kinetic PET
• C. Modified PET
• D. No PET

Answer: (A)

Fast PET is designed to capture peritoneal membrane transport characteristics with four dwell times performed during a single day. This setup makes the test quick and practical for routine clinic use while still providing a reliable transport type classification. The four-dwell-per-day format described matches this modality precisely, which is why it’s the best choice. Other options refer to different testing approaches: kinetic PET uses extra time points to model transport kinetics over a longer period; modified PET tweaks the protocol in ways that don’t necessarily adhere to the four-dwell day format; and no PET means no peritoneal equilibration testing is performed.
