Learning objectives MR cardiac stress imaging (MRCSI) is a non-invasive diagnostic technique that utilizes magnetic resonance imaging (MRI) to assess myocardial ischemia. It includes both functional (myocardial perfusion) and structural (cine imaging & late gadolinium enhancement) investigations of the heart under conditions of pharmacological stress of adenosine.The purpose of exhibition is through cases and illustrations to:-Understand the state-of-the-art MR cardiac stress imaging (MRCSI) protocol and protocol optimization-Highlight common findings, imaging challenges and discuss latest development in hardware and software 
Read more Background Acute chest pain is a common and significant health concern, accounting for a substantial number of morbidity and mortality worldwide.Cardiovascular magnetic resonance (CMR) imaging has evolved significantly over the past three decades, becoming an invaluable tool in cardiac diagnostics. CMR employs several key pulse sequences, each serving specific roles in evaluating cardiovascular structure and function. [fig 1] The development of MR cardiac stress imaging (MRCSI) has further enhanced its utility, particularly in evaluating patients with suspected coronary artery disease (CAD).MRCSI offers significant...
Read more Findings and procedure details Anatomy for MR Cardiac Stress Imaging (MRCSI), imaging planes and AHA 17-segment modelMRCSI utilizes specific imaging planes and segments to comprehensively evaluate the heart's structure and function. The key anatomical aspects and imaging planes include: Short Axis View: [fig 2] Covers basal, mid, and apical levels of the left ventricle Used for stress perfusion imaging and cine imaging Long Axis View: [fig 3] 2-chamber (2ch) 4-chamber (4ch) 3-chamber (3ch) (AHA) 17-segment model(AHA) 17-segment model model is used for standardized myocardial segmentation: Segments 1-6: Basal short-axis slices Segments 7-12: Mid-ventricular short-axis slices Segments 13-16:...
Read more Conclusion In conclusion, MR cardiac stress imaging is a highly valuable and versatile non-invasive technique for assessing myocardial function, detecting ischemia, and evaluating myocardial viability. By combining anatomical, functional, and perfusion imaging into a single examination, it provides comprehensive and detailed information about the heart, enabling accurate diagnosis and guiding treatment strategies for a wide range of cardiovascular conditions, including coronary artery disease, cardiomyopathies, and post-infarction complications.To maximize the diagnostic potential of cardiac MRI, the expertise of radiologists and radiographers remains...
