The Impact Of Nitroglycerine Premedication On Dynamic Stress CT Perfusion Values And Their Correlation With Cardiac MR Imaging
Introduction: Computed Tomography Angiography (CTA) acquisition guidelines recommend the administration of nitroglycerin (NTG) prior to the examination to enhance coronary arteries evaluation. Dynamic stress CT perfusion (dynCTP) is a newer modality that allows quantitative evaluation of myocardial perfusion. A "rest-stress approach" involves performing dynCTP after CTA if abnormalities are detected, making it an attractive one-stop test. However, the cut-off values for myocardial blood flow (MBF) to identify significant hemodynamic lesions vary across studies, making it essential to identify the variables that affect it.
