Craniofacial measurements based on 3D-CT volume rendering: implications for clinical applications
224
TL;DR: 3D-CT volume rendering images using craniometric measurements can be used for anthropological studies involving craniofacial applications and demonstrated no statistically significant difference between interobserver and intraobserver measurements or between imaging and physical measurements in both 3D- CT protocols.

Abstract: Objectives: This study was designed to determine the precision and accuracy of anthropometric measurements using three-dimensional computed tomography (3D-CT) volume rendering by computer systems for craniofacial clinical applications, and to compare the craniometric landmarks using bone and soft tissue protocols. Methods: The study population consisted of 13 cadaver heads that were examined with spiral CT. The archived CT data were transferred to a workstation, and 3D-CT volume rendered images were generated using computer graphics tools. Linear measurements (n=10), based upon conventional craniometric anatomical landmarks (n=08), were identified in 2D-CT and in 3D-CT images by two radiologists twice each independently, and then performed by 3D-CT imaging using a computer graphics systems using bone and soft tissue protocols. In total, 520 imaging measurements were made. The soft tissues were subsequently removed from the cadaver heads and the measurements were repeated using an electromagnetic 3 Space™ ...

TL;DR: The three-dimensional (3D) deformities in patients with congenital facial anomalies, such as cleft lip and palate or hemifacial microsomia, are studied using 3D CT images and the 'skeletograms', which present deformities of craniofacial bones in detail as a 3D wire frame model, are prepared for detailed analysis of the cranioFacial bones' deformities.

Quantitative analysis of spiral computed tomography for craniofacial clinical applications.
TL;DR: Three-dimensional spiral CT can distinguish craniofacial anatomy more accurately with some measurements, and all measurements with 3DCT were found to have satisfactory accuracy in comparison with physical measurements.
