Accordingly, the aim of this study was to survey radiation protection in diagnostic x-ray imaging in ...
In population surveys of the exposure to medical X-rays both the frequency of examinations and the effective dose per examination are required.

On examination only three patients had a palpable hypertrophic pylorus. In 39 patients, a preoperative x-ray examination with contrast was necessary to confirm the diagnosis. A pyleromyotomy was performed in ...
