Just say 'eee' for neck CT

For maximizing airflow and air contrast, having patients hold their breath and form an "eee" with their mouths during MDCT acquisition really opens up the airways, optimizing the visualization of mucosa while imaging the larynx, pharynx, and the rest of the neck, according to researchers from Vanderbilt University in Nashville, TN.

While the MR results didn't hold all the answers, the imaging exam was still worth performing, according to the experts.
