View larger version (120K): [in a new window]   Fig. 1A. —Enlarged adenoid and palatine tonsils associated with dynamic airway motion in 4-year-old girl with no airway symptoms shown on cine MR image (fast gradient-echo; TR/TE, 8.2/3.6 sec; flip angle, 80°; slice thickness, 8 mm; 128 consecutive midline sagittal images; imaging time, 2 min). Cine MR image at one point during respiratory cycle shows adenoid (A) and palatine (P) tonsils. Palatine tonsils are shown as midline soft-tissue mass, which is consistent with enlargement. Hypopharynx, nasopharynx, and oropharynx are patent. Mouth is open.

Cine MR image at another point during respiratory cycle shows decreased diameter of hypopharynx (large arrows) consistent with dynamic patent airway. Previously seen areas of air separating palatine tonsils (P) and pharyngeal walls are no longer present. Posterior nasopharynx (arrowhead) is collapsed on this image, consistent with intermittent collapse. Oropharynx (small arrow) is unchanged, which is consistent with static patent airway. This pattern recurred with each respiratory cycle. A = adenoid tonsils.

Consecutive images show no perceptible motion of hypopharynx, nasopharynx, or oropharynx. Adenoid tonsils are small and palatine tonsils are not seen on midline image, which is consistent with nonenlargement.
