An anthropomorphic airway tree phantom was imaged with both hyperpolarized (HP) 3He MRI using a dynamic projection scan and computed tomography (CT). Airway diameter measurements from the HP 3He MR images obtained using a newly developed model-based algorithm were compared against their corresponding CT values quantified with a well-established method.

IMPORTANCE Few studies have evaluated the pediatric voice objectively using acoustic measurements. Furthermore, consistency of these measurements across time, particularly for continuous speech, has not been evaluated. OBJECTIVES (1) To evaluate normal pediatric voice frequency and perturbation using both time-based and frequency-based acoustic(More)
