Based on a set of 3D vocal tract images obtained by MRI, a 3D statistical articulatory model has been built using guided Principal Component Analysis. It constitutes an extension to the lateral dimension of the mid-sagittal model previously developed from a radiofilm recorded on the same subject. The parameters of the 2D model have been found to be good predictors of the 3D shapes, for most con...

abstract study design . a retrospective radiographic review was undertaken in patients treated for ais. objectives. to determine the most important preoperative factors that affect on postoperative junctional kyphosis complication. methods sagittal spine profilewere measured on the standing radiographs before, after and in the last follow-up visit of the operated patients for ais. the following...

conclusions in the determination via 3d cranial tomography the presence of the parietal bones is important because, in case of agenesis the tension band does not benefit and on the contrary it creates extra stress on cerebral tissue. case report we presented a case with metopic and sagitta suture cranioschisis mimicking bilateral parietal bone agenesis (university of izmir of medicine, turkey, ...

Direct measurements were made on 2,166 lumbar vertebrae of 433 adult negro and caucasoid skeletons. On statistical analysis, forty-five vertebrae in twenty-seven skeletons were found to be stenotic, the mid-sagittal diameter being the significantly reduced dimension. Whereas spinal stenosis syndromes are rare in South African negroes, the lumbar canal is marginally narrower in the negro. There ...

OBJECTIVE To evaluate and compare the skeletal vertical and sagittal effects of the Hyrax expander in Class I, II, and III patients. MATERIALS AND METHODS One hundred and eighty-three patients (91 females, 92 males) with a mean age of 8.7 years and with maxillary bilateral cross-bite and maxillary hypoplasia were analyzed retrospectively. They were divided into three groups according to their...

BACKGROUND Magnetic resonance imaging (MRI) may be useful to diagnose a posterolateral plica syndrome of the elbow joint because this syndrome has less clear clinical features. The purposes of this study were to document mediolateral and sagittal dimensions of a posterolateral synovial fold and to determine the proportion of subjects with the posterolateral plica in asymptomatic elbows. We also...

A schwannoma is a benign tumor arising from a schwann cell and occurs mainly in the nerve sheath in the intradural extramedullary region. Schwannomas have been well described as occurring in the lumbar spine, but total cystic degeneration of schwannomas is rarely reported. The authors describe the clinical and radiographic evaluations and treatment of a rare case of an intraextradural totally c...
