Cardiac Magnetic Resonance for Diagnosis of Neuroendocrine Tumor Metastases to the Right and Left Ventricles with Carcinoid Heart Disease

Figure 2

(a) Axial bSSFP bright blood image through the right ventricle (RV) shows two masses (yellow arrows) involving the anterior RV wall and basilar interventricular septum. (b) Axial T2 spectral presaturation with inversion recovery dark blood image showing T2 hyperintense signal within the two lesions (yellow arrows). (c) Four-chamber bSSFP bright blood image during late systole shows thickening of the anterior leaflet of the tricuspid valve (open arrow) with an abnormal shortened and retracted configuration near the anterior RV wall mass. (d) Early systole image shows a large low signal tricuspid regurgitant flow jet (blue arrow). Notice the anterior leaflet maintaining an abnormal partially open configuration.
