This study will focus on demonstrating the benefits of PCD-CT for clinical indications and findings where the improved spatial and temporal resolution, decreased quantum and electronic noise, improved spectral imaging capabilities, and increased iodine signal are expected to benefit the diagnosis and characterization of CAD and myocardial perfusion defects.
The purpose of this research trial is to determine whether images taken using a Photon Counting Detector CT scanner (PCD-CT) after the patient has received a drug that makes the heart work harder provide clinically important information about the severity of suspected coronary artery disease compared to CT imaging performed without using the drug that causes the heart to work harder.
