[Value of CT and lymphography in the staging of lymphomas (author's transl)]

The contribution of CT is evaluated in association with conventional diagnostic investigations in the staging of lymphomas. The data obtained by means of CT are an integration of those obtained by means of lymphography. On the other hand CT offers elements which cannot be obtained by others methods, especially concerning the retroperitoneal region. This diminishes the average of patients who must undergo laparoscopy and laparotomy. Moreover CT allows to follow the evolution of the disease and to control the results of the treatment.
