[Computer tomography of the mediastinum (author's transl)].

The scope and limitaitons of computer tomography in the diagnosis of diseases of the mediastinum were studied, using a 20 seconds scanner (EMI CT 5005/12). The mediastinal structures can be accurately differentiated and diagnosis is therefore frequently facilitated. In addition to a knowledge of the anatomy, it is important to be familiar with various types of artefact since these may change the degree of attenuation. Additional use of contrast medium is frequently required.
