The two modern imaging methods (echocardiography and magnetic ¬resonance¬ imaging) enable a non-invasive, gentle examination of the heart. Diseases of the heart muscle, heart valves, congenital heart defects, and other conditions can be detected precisely. Echocardiography works with ultrasound waves, and magnetic resonance imaging (MRI) uses magnetic fields to create layered heart images.
In exceptional cases (e.g., when higher resolution is required), an ultrasound probe is inserted through the esophagus. The heart is examined from the inside. The representation is both two- and three-dimensional in high-resolution quality. Like a gastroscopy, the patient is administered a sleeping pill through a vein to keep the discomfort as low as possible.
