Replaceability of Fluoroscopy and Ultrasound in the Evaluation of Hemidiaphragm Excursion

University of Aarhus42 enrolled

Overview

Precise measurement of diaphragm function is difficult. Several methods exist. No are sufficiently validated. With this study, the investigators wish to investigate the validity of different ultrasound and radiological methods and compare them with inspiratory pressure measurements.

Fluoroscopy assessment of diaphragm motility is obtained and simultaneously correlated to sonographic assessments of motility.
