Abstract
The standard technique for computed tomographic evaluation of the larynx utilizes 5-mm contiguous transaxial sections. Multiplanar images reformatted with these sections have not been of clinical use. We have evaluated the practicality of utilizing coronal and sagittal reformatted images produced from contiguous 1.5-mm transaxial sections. The technique of rapid sequential scanning with automatic table incrementation allows 36 contiguous thin section scans to be acquired in less than 9 minutes. Phantom studies showed a marked improvement in spatial resolution with thin section reconstructions. Preliminary clinical evaluation shows visualization of smaller structures with improved edge definition of both low- and high-contrast structures.
