[Hysterosalpingography with digital image intensification radiography].

Digital image intensifier radiography (Siemens/Polytron) offers the chance to reduce patient exposure dose in hysterosalpingography (HSG) by 85% compared with conventional film/screen radiography and by 11% compared with the 100 mm technique. By appropriate choice of the parameters the signal-to-noise ratio was adapted to the detectability of the diagnostic information (variation of the dose). Thirty patients were examined with the 28 cm image intensifier and an image intensifier input dose of 50 microR. The diagnostic image quality was assessed being aware of the results of laparoscopy or surgery; in 29 cases the quality was classified very good without any limitations. Digital image intensifier radiography offers additional advantages over conventional x-ray units: the images are directly available on the monitor and offer the possibility of post-processing.
