Sleep apnoea syndrome, characterized by airway obstruction, causes daytime sleepiness and snoring. Magnetic resonance imaging and ultrasound show promise for diagnosing and measuring obstruction during sleep.

Area of Science:

  • Medical Imaging
  • Sleep Medicine
  • Respiratory Physiology

Background:

  • Sleep apnoea syndrome is a common disorder characterized by upper airway obstruction during sleep.
  • Symptoms include excessive daytime sleepiness and loud snoring.
  • Accurate localization and quantification of airway obstruction are crucial for effective treatment.

Purpose of the Study:

  • To review and compare techniques for localizing and quantifying upper airway obstruction in sleep apnoea syndrome.
  • To identify the most promising imaging modalities for clinical use.

Main Methods:

  • Review of existing literature on imaging techniques for sleep apnoea.
  • Analysis of the capabilities and limitations of various methods, including magnetic resonance imaging (MRI) and ultrasound.

Main Results:

  • Several techniques exist for assessing airway obstruction during sleep, each with limitations.
  • Magnetic resonance imaging (MRI) and ultrasound demonstrated significant potential for accurate localization and quantification.

Conclusions:

  • No single technique is currently ideal for evaluating upper airway obstruction in sleep apnoea.
  • MRI and ultrasound offer the most promising avenues for future diagnostic development and clinical application.
