Cardiac MRI Assessment in London
Cardiac magnetic resonance can assess heart structure, function, blood flow and tissue characteristics without ionising radiation. The protocol is tailored to the clinical question.
A detailed scan chosen for a defined question.
Cardiac MRI combines moving images of the heart with measurements of pumping function, blood flow and tissue composition. It can be particularly useful when echocardiography leaves an important question unanswered or when tissue characterisation may influence diagnosis and treatment.
Dr Bhuva reviews the reason for imaging, previous ECG and scan results, symptoms, kidney function, medication and any implanted metal or cardiac device. The aim is to choose the most informative protocol while avoiding unnecessary testing.
Questions cardiac MRI may address
- Heart-muscle disease and cardiomyopathy
- Inflammation or suspected myocarditis
- Scar and previous heart injury
- Heart size and pumping function
- Valve disease and blood-flow measurements
- Selected congenital or aortic conditions
- Blood supply using stress perfusion where appropriate
Preparation, scanning and interpretation.
Clinical review
Existing records are considered first so the scan complements rather than repeats previous testing.
Tailored protocol
The image sequences and use of contrast depend on the suspected condition and the decision the scan needs to inform.
Clinical explanation
Results are interpreted alongside symptoms, examination and other investigations, followed by clear next steps.
Cardiac MRI questions.
What can a cardiac MRI show?
Cardiac MRI can assess heart size, pumping function, blood flow and tissue characteristics. Depending on the protocol, it may help evaluate cardiomyopathy, inflammation, scar, valve disease or blood supply. The scan should be selected to answer a specific clinical question.
Does every cardiac MRI require contrast?
No. Some questions can be answered without gadolinium contrast, while others require it for tissue characterisation or scar assessment. Kidney function, pregnancy, previous reactions and the clinical purpose are reviewed before contrast is used.
Evidence and review.
General preparation information is available from the NHS guide to MRI scans. Individual cardiac protocols and contrast decisions require clinical review.
