Comparison of Spiral Computed Tomography and Cone-Beam Computed Tomography
Imaging is a highly dependent technology in the clinical assessment of a patient. With respect to the dental field, imaging has travelled a long way from the conventional radiographs to modern techniques like the computed tomography (CT) and the cone-beam computed tomography (CBCT). This article describes the evolution made in the CT in the field of dental imaging and attempts to compare the CT...
متن کاملVolumetric accuracy of cone-beam computed tomography
PURPOSE This study was performed to investigate the influence of object shape and distance from the center of the image on the volumetric accuracy of cone-beam computed tomography (CBCT) scans, according to different parameters of tube voltage and current. MATERIALS AND METHODS Four geometric objects (cylinder, cube, pyramid, and hexagon) with predefined dimensions were fabricated. The object...
متن کاملAccuracy of densitometry of two cone beam computed tomography equipment in comparison with computed tomography
BACKGROUND The use of oral implants has been growing, and cone beam computerized tomography (CBCT) has become the method of choice for oral and maxillofacial radiology. OBJECTIVE To assess the accuracy of bone densitometry in two different CBCT devices in comparison with MDCT (multi-detector CT). METHODS Different concentrations of urografin, including 2.5%, 5%, 7.5%, 10%, 12.5%, were prepa...
متن کاملAssessment of Accessory Mental Foramen by Cone-Beam Computed Tomography
Introduction: Any foramen in the buccal surface of mandibular body that transfers mental nerve and vessels except mental foramen, is called Accessory Mental Foramen (AMF). The objective of this study was the determination of the AMF using cone-beam computed tomography (CBCT). Materials and Methods: this descriptive study was done on 180 CBCT projections which were selected by convenience samp...
متن کاملPrevalence of Idiopathic Osteosclerosis on Cone Beam Computed Tomography Images
Objectives: This study was performed to investigate the prevalence of idiopathic osteosclerosis on cone beam computed tomography (CBCT) images of patients. Methods: In this descriptive, cross-sectional study, 240 CBCT scans of patients (125 women, 115 men) referred to a private oral and maxillofacial radiology clinic in Tehran in 2013 were selected and evaluated. Presence of idiopathic osteosc...
