Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
If participants agree to participate in this study, researchers will first interview participants and review the past medical record in order to document the medical history. When the screening procedures confirm that participants are eligible to participate in the study, participants will receive one dose of the non-therapeutic administration of a radioactive tracer called N-13 ammonia(13NH3) , then undergo one total body 13NH3 PET/CT Scan (uEXPLORER) to determine the blood flow value of the brain, kidney and other organs. The total body 13NH3 PET/CT Scan will allow investigators to observe and analyze the real-time blood flow differences between patients with between healthy controls and decreased cardiac function.
