[Are conventional roentgen technics for tbc diagnosis still acceptable?]

Image quality in chest radiography has to be high enough that even subtle pulmonary abnormalities can be easily visualised. Conventional screen/film radiographs obtained with 200 to 400 speed systems fulfil this requirement well enough. Large screen and slit beam image intensifier systems that have replaced fluoroscopy screens, yield equivalently good results. The amber system and storage phosphor digital radiography systems are efficient alternatives. Radiation exposure is generally low and decreased further if image intensifiers are used. Conventional technique with highly sensitive film/screen combinations has been approved for diagnosis of pulmonary tuberculosis.
