Preliminary Study of Pediatric Diaphragmatic Elastography

"The measurement of diaphragmatic stiffness by shear waves is performed with a high-frequency linear ultrasound probe, intercostally, during apneas lasting a few seconds.~After quantitative diaphragm thickness measurements, the ultrasound probe positioning is unchanged and regions of interest are placed in the patient's diaphragm thickness as well as in the adjacent liver or spleen (baseline). A stiffness result is obtained in kPa.~The elastography measurement extends the duration of the ultrasound scheduled as part of patient care by only 10 minutes.~The examination is painless and non-invasive."
