Noninvasive evaluation of the pediatric airway: a recent advance.

Visualization of the pediatric airway is now possible by new noninvasive radiologic methodology--the magnification high kilovoltage (Mag-high KV) technique. Clinical expamles of airway diseases are presented to show the ease and utility by which precise diagnoses can be made. The dynamic aspect of airway evaluation is discussed. The Mag-high KV technique is also valuable for the number of invasive procedures it prevents.
