Tuberculosis-x-ray The diagnosis of<unk>  is often difficult to make. In particular, restrictive cardiomyopathy has many similar clinical features to<unk> , and differentiating them in a particular individual is often a diagnostic dilemma. * Chest X-Ray - pericardial calcification (common but not specific), pleural effusions are common findings. * Echocardiography - the principal echographic finding is changes in cardiac chamber volume. * CT and MRI - CT scan is useful in assessing the thickness of pericardium, calcification, and ventricular contour. Cardiac MRI may find pericardial thickening and pericardial-myocardial adherence. Ventricular septum shift during breathing can also be found using cardiac MRI. Late gadolinium enhancement can show enhancement of the pericardium due to fibroblast proliferation and neovascularization. * BNP blood test - tests for the existence of the cardiac hormone brain natriuretic peptide, which is only present in restrictive cardiomyopathy but not in<unk>  * Conventional cardiac catheterization * Physical examination - can reveal clinical features including Kussmaul's sign and a pericardial knock.
