Comparative Analysis of T2 and T1 MRI for Coronary Artery Disease Detection

Abstract

Coronary artery disease (CAD) remains a significant contributor to global mortality. Non-invasive imaging modalities are indispensable for the diagnosis and management of CAD. Magnetic Resonance Imaging (MRI) has emerged as a promising tool due to its inherent lack of ionizing radiation and its capacity to provide detailed anatomical and functional insights. This article presents a comprehensive review of the current literature, comparing the utilization of T2 and T1 MRI techniques in CAD detection. We highlight the advantages, limitations, and specific clinical applications of each modality. T1 MRI with contrast enhancement excels in visualizing coronary artery walls and plaques, assessing myocardial perfusion, and detecting scarring. In contrast, T2 MRI, without the need for contrast agents, is invaluable for detecting myocardial edema, a key indicator in the diagnosis of acute myocardial infarction. The selection between T2 and T1 MRI should be judiciously based on the specific clinical question and patient considerations.
