Cardiac MRI provides a non-invasive, multiparametric reference standard for characterizing suspected cardiac tumours and differentiating benign from malignant lesions.
May guide non-invasive assessment of cardiac masses; leaves open need for prospective validation against histopathology.
Cardiac magnetic resonance imaging (MRI) is the reference standard technique for assessment and characterization of a suspected cardiac tumour. It provides an unrestricted field of view, high temporal resolution and non-invasive tissue characterization based on multi-parametric assessment of the chemical micro-environment. MRI exploits differences in hydrogen proton density in conjunction with T1 and T2 relaxation properties of different tissues to help differentiation normal from abnormal and benign from malignant lesions. In this article we review specific cardiac MRI techniques, tumour protocol design and the appearance of the spectrum of histologically benign tumours.
