This study will focus on demonstrating the benefits of Photon Counting Detector CT Scan (PCD-CT) for clinical indications and findings are expected to benefit the diagnosis and characterization of Coronary Artery Disease (CAD) and myocardial perfusion defects.

Specific Aim:  

In patients, measure the clinical impact of cardiac PCD-CT on patient diagnosis and management

The purpose of this study is to determine the tradeoffs between CT image quality and patient radiation dose in a way that moves beyond current simple models (e.g. standard deviation and CTDIvol) by investigating the relationships between task-based metrics of image quality, observer performance, patient size, and patient dose.

The purpose of this study is to compare the ability to identify uric acid renal stones between alternate CT scanning techniques and the current dual-source CT scanning technique.
