Our group has recently developed a novel real-time 3D MRI of the upper airway imaging which has the potential to provide complete anatomical information of the pharyngeal airway with sub-second temporal resolution and <2 mm isotropic spatial resolution. We have applied this technique to overweight and obese adolescents who snore, and have been able to observe and classify the patterns of upper airway narrowing and obstruction during respiratory events such as central or obstructive sleep apneas during natural sleep.
