The value of direct magnification radiography of the hand and the wrist has been studied in 128 patients affected by rheumatic diseases. Only in a small group (3.17%) magnification determined a higher percentage of correct diagnosis; in the 17.06% of cases direct magnification radiography provided useful increase in information but did not change the diagnosis correctly reached by conventional techniques. In most cases (79.76%) magnification provided only a better image quality but no more information helpful for the diagnosis, because of the high level achieved by conventional techniques. Therefore direct magnification radiography must be used only in selected cases and not as routine radiographic technique.
