In this video, he highlights how MRI provides detailed tissue characterisation, helping identify inflammation, scarring and underlying heart disease. Watch Dr Assomull's answer (00:59).
CT coronary angiogram vs invasive angiogram: what is the difference?
Dr Ravi Assomull explains the differences between CT coronary angiography and invasive angiograms. In this video, he outlines how CT scans provide a non-invasive way to detect plaque, while invasive angiography allows both diagnosis and treatment such as stenting. Watch Dr Assomull's answer (01:23).
Should you worry about an invasive angiogram?

What is advanced cardiac imaging and when is it recommended?
Dr Ravi Assomull describes advanced cardiac imaging techniques such as MRI and CT scans. In this video, he explains when these tests are used to detect plaque, inflammation or structural heart disease beyond standard imaging. Watch Dr Assomull's answer (01:06).
What happens during a cardiac MRI?
Cardiac MRI is a powerful, radiation-free imaging technique that offers detailed insights into your heart’s structure and function. In this video, Dr Ravi Assomull explains how cardiac MRI is used to diagnose conditions like cardiomyopathies, myocarditis, and coronary artery disease and walks you through exactly what to expect on the day of your scan. Learn how stress MRI, contrast agents, and high-resolution imaging help us detect hidden causes of chest pain, breathlessness, and more. Watch Dr Assomull's answer (3:21).
What is a CT coronary angiogram scan?
Considering a CT coronary angiogram or been referred for one? In this video, consultant cardiologist Dr Ravi Assomull explains what the test involves, who it’s for, and how it helps assess your risk of heart disease. Learn how the scan detects calcium build-up, artery narrowing, and dangerous soft plaque that could lead to heart attacks. Dr Assomull also explains how modern scanners minimise radiation exposure.
