Inspiration chest radiography by lateral recumbency. | In lateral recumbency the uppermost lung is in a state of relative inspiratory apnoae. This physiological phenomenon may be exploited to obtain inspiratory chest films in children and uncooperative adults and as an improvement on the sitting film of patients unable to stand. It also tests to some extent the pulmonary c... | 639,453 | [

The radiological assessment of gastric acid output in chronic renal failure. | The presence of hypertrophied gastric and duodenal mucosa as seen in the barium meal examination has been widely accepted as indicating an increase in gastric acid content. The present study of 31 uraemic patients undergoing maintenance haemodialysis suggests that in the uraemic patient this is not the case. Nineteen s... | 639,457 | [
