Benign tumours and other masses are far more common than malignant tumours and of the malignancies metastases are many times more common than primary cardiac tumours. Masses in or around the heart can be seen on echocardiography or CT and further investigation is required to separate artefact and innocent structures from true masses potentially of concern to the patient and clinician. CMR is highly valuable in the assessment of cardiac masses due to its versatility in image planes and excellent ability to discriminate tissue types based on their MR properties and their response to gadolinium contrast. CMR can differentiate normal from abnormal myocardium identify the size location and anatomy of a mass and can often provide a likely diagnosis. While CMR may not always provide a definitive pathological diagnosis it can usually identify abnormal tissue and determine the likelihood of a tumour based on the characteristics of the mass. It may also guide surgery and or biopsy if this is deemed appropriate. This page intentionally left .
