Lead Sponsor:
Medical University of South Carolina
Conditions:
Chest Pain
Eligibility:
All Genders
18-85 years
Phase:
NA
Brief Summary
To assess the ability of a novel 3rd generation dual-source CT system to demonstrate myocardial perfusion in a cohort of patients presenting to the Chest Pain Center with acute chest pain.
Detailed Description
The investigators will assess the latest generation of CT scanner for heart disease detection. On this new machine the investigators will analyse the ability of the machine to show the delivery of blo...
