A flexible 16-channel custom coil array for accelerated imaging of upper and infraglottic airway at 3 T.

Purpose: To develop a custom coil and evaluate its utility for accelerated upper and infraglottic airway MRI at 3 T.

Methods: A 16-channel flexible and anatomy-conforming coil was developed to provide localized sensitivity over upper and infraglottic airway regions of interest. Parallel-imaging capabilities were compared against existing head and head-neck coils.
