78 year-old woman, with malignant neoplasm of thyroid gland and filling defect noted in CT, echo not conclusive, referred for MRI to assess LV thrombus. Left VentricleThe left ventricle is normal in size and low normal systolic function. The overall LV ejection fraction is 52%, the LV end diastolic volume index is 58 ml/m2 (normal range: 65+/-11), the LVEDV is 116 ml (normal range 109+/-23), the LV end systolic volume index is 28 ml/m2 (normal range 18+/-5), the LVESV is 56 ml (normal range 31+/-10), the LV mass index is 40 g/m2 (normal range 67+/-11), and the LV mass is 79 g (normal range 114+/-24). There are no regional wall motion abnormalities present. Septal dyssynergy of unclear significance. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. There is no thrombus in the LV.Left AtriumThe left atrium is normal in size.Right VentricleThe right ventricle is normal in size and systolic function. The overall RV ejection fraction is 60%, the RV end diastolic volume index is 55 ml/m2 (normal range 69+/-14), the RVEDV is 109 ml (normal range 110+/-24), the RV end systolic volume index is 22 ml/m2 (normal range 22+/-8), and the RVESV is 44 ml (normal range 35+/-13). Right AtriumThe right atrium is normal in size. Aortic ValveThe aortic valve opens widely and there is no significant aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is mild mitral regurgitation.Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is no significant tricuspid regurgitation.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size. The ascending aorta is mildly dilated with dimensions 38 x 38. Pulmonary VeinsAll four pulmonary veins drain normally into the left atrium.Pulmonary ArteryThe main pulmonary artery is normal in size. Venous AnatomyThe SVC and IVC drain normally into the right atrium. PericardiumThere is mild to moderate pericardial effusion measuring 13 mm along the RV free wall and LV anterior wall. Extracardiac FindingsLeft lung apical density noted. This was characterized on recent CT (08/14). Also noted mediastinal adenopathy. This study is not designed for the specific evaluation of extra-cardiac findings; therefore, the differentiation between artifacts and real extracardiac pathology may be difficult. If clinically indicated, a separate dedicated evaluation should be considered.
1. The left ventricle is normal in size and low normal systolic function. The overall LV ejection fraction is 52%. No mass/thrombus appreciated in the left ventricle on this study.2. The right ventricle is normal in size and systolic function. The overall RV ejection fraction is 60%3. The ascending aorta is mildly dilated with dimensions 38 x 38.4. There is mild to moderate pericardial effusion measuring 13 mm along the RV free wall and LV anterior wall.
