A Study of Regadenoson in Subjects Undergoing Stress Myocardial Perfusion Imaging (MPI) Using Multidetector Computed Tomography (MDCT) Compared to Single Photon Emission Computed Tomography (SPECT)
brief summary
The purpose of this study is to compare Multidetector Computed Tomography (MDCT) and Single Photon Emission Computed Tomography (SPECT) stress myocardial perfusion imaging (MPI) with regadenoson in order to detect the presence or absence of reversible defects.
detailed description
All participants will be randomized to one of two imaging sequences: rest/stress SPECT on Day 1 followed by stress/rest MDCT on Day 2 or stress/rest MDCT on Day 1 followed by rest/stress SPECT on Day 2. All stress scans will involve the injection of regadenoson as the pharmacologic stress agent.
