[Quantitative determination of diaphragmatic motility using ultrasound. Comparison with pulmonary function test parameters and thoracic radiography]

Abstract

Sonography, combined with a geometrical simulation-model, can be used to estimate parameters of pulmonary function tests (PFT). The sensitivity for changes of PFT may be increased by repetitive examinations. This simple inexpensive method is easily reproducible. Additional information concerning diaphragmatic motility is obtained. The value of this method is improved by taking geometric parameters directly from chest radiograph using a suitable computer program.
