Reconstruction of three-dimensional images of the pharynx in patients with sleep apnea using three-dimensional fast low-angle shot MR imaging.

turbo-FLASH sequences, image slices are 20 mm at largest. To analyze the entire pharynx dynamically, imaging has to be performed from slightly different positions, and then each region has to be displayed in cine mode. Also, by imaging from one direction on 2D turbo-FLASH, obtaining a stereoscopic image of the obstructed region is impossible. For example, imaging in the sagittal plane will not show movement toward the lateral
