Overview

Cardiac MRI is regarded as the gold standard after echocardiograph for evaluating a suspected cardiac tumor due to its unique ability to provide non-invasive tissue characterization in conjunction with excellent temporal resolution and absence of exposure to ionizing radiation.

MRI

  • Cardiac MRI scan may be further used to investigate the cardiac tumors after initial diagnostic testing with an echocardiograph.
  • Findings on MRI suggestive of/diagnostic of different cardiac cancers include:
Cardiac Tumors MRI Findings
Tumor MRI Finding
Myxoma * Oval mobile left atrial lesion
Rhabdomyoma * Multiple masses isointense to muscle tissue on T1 images
  • Hyperintense on T2 images[1]
Cardiac Fibroma * Solitary mass
  • Low intensity on T2 weighted image[1]
Fibroelastoma * T1 and T2 weighted images show uniform intermediate signal intensity similar to myocardium
  • Homogeneous late gadolinium contrast enhancement[1]
Hemangioma * Intermediate density on T1 images
Cardiac Lipoma * Epicardial or intramural lesion
  • High intensity on T1 weighted image
  • Drop out on fat saturation images[1]
Paraganglioma * Well defined lesion arising from atrial walls or septum
  • Bright on T2 weighted imaging[1]
