Nonischemic Cardiomyopathies.

Computed tomography of the heart can characterize and differentiate various forms of nonischemic cardiomyopathy, which are covered individually in this article. With its excellent spatial and ever-improving temporal resolution, computed tomography scanning can delineate cardiac function, anatomy, and myocardial tissue characterization. Various cardiac computed tomography techniques can be tailored to the relevant clinical question, as discussed in the article. Although cardiac computed tomography scanning is not often the primary modality for myocardial evaluation, decreasing radiation doses and emerging applications make this fast and relatively economical examination a useful tool in the evaluation of the patient with cardiomyopathy.
