CMR for malignant cardiac tumors : Diagnosis, approach, and follow-up
(2022) p.203-224- Abstract
Cardiac magnetic resonance (CMR) is the gold standard noninvasive imaging modality to assess tissue characteristics in vivo which gives it a unique advantage in discriminating benign cardiac masses from malignant tumors. CMR also provides visualization of tumor invasion, hemodynamic effects, and location relative to surrounding cardiac and extracardiac structures. These features make CMR an essential tool for diagnosis and management of cardiac tumors. The following sequences form part of a comprehensive CMR exam: cine imaging (e.g. balanced steady-state free precession (bSSFP)), T1/T2-weighted black-blood (BB) images, T1/T2 mapping, first-pass perfusion, and delayed enhancement imaging. The characteristics of the tumor are often... (More)
Cardiac magnetic resonance (CMR) is the gold standard noninvasive imaging modality to assess tissue characteristics in vivo which gives it a unique advantage in discriminating benign cardiac masses from malignant tumors. CMR also provides visualization of tumor invasion, hemodynamic effects, and location relative to surrounding cardiac and extracardiac structures. These features make CMR an essential tool for diagnosis and management of cardiac tumors. The following sequences form part of a comprehensive CMR exam: cine imaging (e.g. balanced steady-state free precession (bSSFP)), T1/T2-weighted black-blood (BB) images, T1/T2 mapping, first-pass perfusion, and delayed enhancement imaging. The characteristics of the tumor are often described as hyper/iso/hypo-intense, meaning higher, equal to, or lower signal intensity compared to normal myocardium. For instance, the extensive vascular networks associated with malignant tumors often present as hyperintense on first-pass perfusion and on late gadolinium enhancement (LGE) images. The high volume of intracellular free water content in malignant tumors and the frequently observed surrounding edema may lead to longer T1 and T2 relaxation times. At the same time, necrosis and hemorrhage within the tumor often result in heterogeneous signal on T1W and T2W BB images. The newer T1 and T2 mapping techniques provide quantitative T1 and T2 values, instead of the relative grayscale obtained through T1W and T2W BB imaging, providing an opportunity to further advance the diagnosis of malignant cardiac tumors.
