title: [Direct radiographic magnification of the hand: study of erosions in rheumatoid arthritis].
abstract: Plain films and direct magnification radiographs of the hands were performed in 34 patients affected by rheumatoid arthritis, using mammographic x-ray tube, achieved with 0.1 mm microfocus, and 1.85 X magnification factor. Direct magnification radiography has provided essential or useful diagnostic data in 44% of cases, particularly in recognizing early skeletal erosions. Nevertheless direct magnification radiography must be used only in those cases in which traditional mammographic techniques do not supply satisfactory results.
