Clinical efficacy of prototype T1-PETRA was evaluated in
39 neonates' airway systems by rating the tracheal and
three bronchial branching ([1] right upper bronchus, [2]
left upper and lower bronchi, and [3] right middle and
lower bronchi). In spite of babiesf breathing and
motions, 135 out of 156 branching (86%) were visualized
and 81(51%) were rated suitable for radiological
evaluation by the consensus of two pediatric
radiologists. T1-PETRA demonstrates high potential for
neonatal neck and chest imaging including the airway
system without radiation exposure and could be an ideal
substitute for 3D-CT of the airway.
