Medicine is, fortunately, constantly evolving. Imaging diagnosis is no exception. Technical improvements guarantee further developments in diagnosis. Computed tomography (CT) and magnetic resonance imaging (MRI) have attained a recognized value in the diagnosis of the heart, which is continuing to increase.
