Double contrast knee arthrography. Some new points of technique including the use of Dimer X

A short review of the development of techniques in knee arthrography is given, together with a full account of the author's technique, including the use of a specially designed pad and a frame to facilitate radiography and a new method to demonstrate the cruciate ligaments. Side effects in a group of patients examined using Dimer X as the positive contrast medium are compared with those in a group of patients who were examined using Urografin 60%. Comparason of the radiological advantages of Dimer X examinations with Urografin 60% examinations has been made. A possible method to distinguish normal from damaged or degenerate tissues is suggested. The author concludes that Dimer X is the positive contrast medium of choice at the present time.
