Abstract
The position of the upper poles of the kidneys in relation to the 12th thoracic vertebra was evaluated on each of the 3 nephrograms of 32 cooperative patients undergoing excretory urography during evaluation for hypertension. Mean change in kidney position relative to vertebral position between nephrograms varied from a mean 4.9 mm on films taken during inspiration to 7.7 mm on films obtained in expiration. Diaphragmatic positional changes could be evaluated in 12 patients; mean change in diaphragmatic position between nephrogram exposures was 8.0 mm. Considerable variation in diaphragm position does occur during successive breath-holding attempts for cross-sectional imaging.This publication has 1 reference indexed in Scilit:
