Evaluation of mammography unit and rare earth screens for high resolution hand radiography

Hand radiographs of an unselected group of ten patients obtained with a mammographic unit and a rare earth screen-film combination were compared with those obtained with a standard radiographic unit and industrial film, as well as those obtained with a standard radiographic unit and xeroradiography. Radiation dosages and costs were calculated. The radiographs obtained by the first method were most acceptable as regards to radiation dosage and quality.
