This review highlights the diagnostic and prognostic value of cardiac magnetic resonance and computed tomography in the assessment of cardiomyopathies. While echocardiography remains the first-line imaging modality, cardiac magnetic resonance (CMR) and cardiac computerized tomography (CCT) offer superior tissue characterization, morphological assessment, and functional evaluation, crucial for phenotyping cardiomyopathies into hypertrophic, dilated, restrictive, arrhythmogenic, and non-dilated left ventricular subtypes. For hypertrophic cardiomyopathy, CMR enables precise identification of fibrosis, hypertrophy distribution, and risk stratification for sudden cardiac death. CMR is pivotal in identifying phenocopies, like cardiac amyloidosis and Anderson–Fabry disease, and differentiating between pathological and physiological remodeling in athlete's heart. For dilated cardiomyopathy, late gadolinium enhancement, T1 mapping, and extracellular volume measurements aid in distinguishing etiologies and predicting adverse outcomes. In arrhythmogenic right ventricular cardiomyopathy, CMR demonstrates superior sensitivity for detecting structural abnormalities in the right ventricle, and the presence of fibrosis which is associated with arrhythmic risk.

This definition encompasses pathologies with very different pathological backgrounds, ultimately resulting in PH. For this reason, the latter can be possibly (though seldom) accompanied by cardiomyopathies, pathologies characterized by a structural and functionally abnormal myocardium not secondary to coronary disease, hypertension, valvular disease, or congenital heart disease. Notable examples of these diseases are sarcoidosis (a multi-systemic inflammatory granulomatous disease, possibly involving the lung and the heart), systemic sclerosis (SSc) (a connective tissue disease [CTD], possibly causing interstitial lung disease [ILD], direct as well indirect involvement of the cardiovascular system), and chronic kidney disease (CKD) (a progressive pathological process involving the kidneys, with multi-systemic involvement and possible development of a peculiar form of cardiomyopathy, i.e., uremic cardiomyopathy [UC]). The diagnostic work-up of patients with coexistent PH and cardiomyopathies implies the use of multiple imaging techniques, with computed tomography (CT) and cardiovascular magnetic resonance (CMR) being among the most important. The knowledge of CT and MRI findings, together with a suggestive clinical picture, forms the basis for a correct diagnosis, therefore it is important for the radiologist to recognize them in complex clinical scenarios.
