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.
