INVESTIGATION OF A POSITRON-EMITTING LONG-CHAIN FATTY ACID (18F-FTHA), FOR IMAGING OF THE INTESTINAL AND CENTRAL LYMPHATIC SYSTEM
University of Pennsylvania
Summary
The project will be performed over a period of approximately two years. In the first year the \[18F\]FTHA tracer will be developed, optimized, and tested on normal volunteers. During the second year, the tracer will be investigated on patients with suspected obstruction of the thoracic duct (TD).
Description
Initially up to 10 healthy adult volunteers will be recruited for the study. All subjects will be instructed to fast overnight before the scan visit. On the study day, subjects will be fasting, and then asked to consume an Ensure drink after \[18F\]FTHA administration and before imaging begins. Tracer administration vial oral capsules and PET/CT imaging: All subjects will receive approximately 1.0 -1.5 mCi (approximately 37-55 MBq) of \[18F\]FTHA administered orally followed by dynamic imaging for up to 4 hours, with breaks between scan sessions (Figure 4) on a whole-body PET/CT system. An ad…
