[CT and MRI in the diagnosis of cardiomyopathy].
Two new noninvasive imaging modalities, electron beam computed tomography (EBCT) and magnetic resonance imaging(MRI), have emerged in recent years and have provided images of the heart with high temporal and spatial resolution. They provides accurate information of myocardial thickness, ventricular shape and volume, wall motion, and ventricular function in patients with cardiomyopathy. In addition, myocardial damage can be evaluated using contrast media. They can give unique diagnostic information above and beyond that of more traditional noninvasive modalities such as two-dimensional echocardiography, left ventriculography and radionuclide technique because both modalities acquire images in three dimensions. They have a possibility to become an alternative modality of the left ventriculography in the diagnosis of cardiomyopathy.
