ABSTRACT

Cardiac masses are typically initially imaged with echocardiography, MRI, and PET/SPECT. If dedicated CT imaging is planned, the protocol should be modified for the specific clinical question. If a mass with suspected mobility is evaluated, retrospective gated acquisition modes, optimally on scanners with high temporal resolution, should be used to limit motion artefact. Cardiac masses are described with regard to size, location, and spatial relationship to adjacent structures. It is important to evaluate the border of the mass, the density of the mass, its homogeneity, and contrast enhancement after contrast administration. Common benign tumours are atrial myxomas. Myxomas often originate from the left atrium or mitral annulus with a stalk, and may demonstrate tumour calcification.
