Cardiac Water and Fluoromethane Cardiac PET

This study has been completed.

In this study we are looking at the blood flow to the heart using two different chemical tags or tracers that give off a low level of radiation. The tracers used in this study are called O15-water and F17-fluoromethane. These tracers mix with the blood and will move through the body. The researchers will use positron emission tomography (PET scans)to track the tracers as they moe through the heart and chest.

Condition Intervention
Healthy Volunteers Procedure: Cardiac PET imaging- rest and pharmacological stress

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Comparison of Cardiac Perfusion by O15-water and F17-fluoromethane PET

Further study details as provided by University of Wisconsin, Madison:

Primary Outcome Measures:
  • -- implement myocardial perfusion quantification for O15-labeled water at rest and with pharmacologic stress, [ Time Frame: assess at time of PET scan ]
  • -- determine the biodistribution of fluoromethane in the thorax to see if it is usable for a cardiac perfusion tracer, [ Time Frame: assess at time of PET Scan ]

Secondary Outcome Measures:
  • --develop initial methods for quantification of myocardial perfusion if applicable for labeled fluoromethane. [ Time Frame: assess at time of PET scan ]

Estimated Enrollment: 10
