We demonstrated high-resolution multiplanner reformation (MPR) and 3-dimentional CT (3D-CT) imaging of Eustachian tube (ET) using a 1-mm, 8-row multislice CT scanner.<BR>CT scans were performed in 5 normal adult volunteers during quiet breathing and the Valsalva maneuver.<BR>Bony portion of ET was clearly detected on MPR, however cartilaginous portion of the ET was still elusive during quiet breathing scan.<BR>MPR and 3D-CT images during Valsalva maneuver improved visualization of cartilaginous portion of the ET and surrounding soft tissues including cartilage, muscle and fat.<BR>Imaging of the ET obtained by multislice CT during the Valsalva maneuver can propose further investigation for various middle ear disorders.
