PURPOSE We sought to further localize radioiodine activity in the mouth on post-thyroid cancer therapy imaging using single-photon emission computed tomography/computed tomography (SPECT/CT). MATERIALS AND METHODS We retrospectively reviewed all patients (58) who underwent thyroid cancer therapy with iodine-131 (131I) at our institution from August 2009 to March 2011 whose post-therapy radioi...

Primary intraosseous lymphoma is rare and there are few case reports manifesting with a mass in the mandible. Thus, we retrospectively reviewed and analyzed the clinical characteristics, treatment, and outcome of extranodal non-Hodgkin’s lymphoma (NHL) with initial mandibular symptoms in our department. At initial treatment of dental clinics, dentists had diagnosed as dental or gingival disease...

This study was designed to clarify the three dimensional features of naso-maxillary complex in cleft lip and palate (CLP) by using computed tomography (CT) and to examine its change following an upper dental arch expansion. Sequential CT images with 2mm-thickness were obtained for 11 unilateral CLP boys (UCLP), 6 bilateral CLP boys (BCLP) and 4 boys without cleft (non-cleft). Additionally, two ...

background: a comprehensive database, comprising geometry and properties of human teeth, is needed for dentistry education and dental research. the aim of this study was to create a three-dimensional model of human teeth to improve the dental e-learning and dental research.   methods: in this study, a cross-section picture of the three-dimensional model of the teeth was used. ct-scan images wer...

In large disasters, dental record plays an important role in forensic identification. However, filing dental charts for corpses is not an easy task for general dentists. Moreover, it is laborious and time-consuming work in cases of large scale disasters. We have been investigating a tooth labeling method on dental cone-beam CT images for the purpose of automatic filing of dental charts. In our ...

Because of the interest in reducing the time and radiation required for screening sinuses with CT, we compared the quality of conventional coronal CT images with coronally reconstructed, axially acquired spiral CT images. The spiral reconstructions compared favorably with the conventional images and had significantly less motion and dental amalgam artifacts.

Cone beam computed tomography (CBCT) is a diverse 3D x-ray imaging technique that has gained significant popularity in dental radiology the last two decades. CBCT overcomes limitations of traditional two-dimensional and enables accurate depiction multiplanar details maxillofacial bony structures surrounding soft tissues. In this review article, we provide an updated status on summarise technica...

BACKGROUND The aim of this study was to investigate the use of a newly developed micro-computed tomography (micro-CT) system for the diagnosis of oral pathologies in small animals, using the rabbit as a model. The diagnosis of dental diseases in rabbits is usually based on oral endoscopy and radiographic imaging, but detailed pathological diagnosis using these methods is frequently difficult. M...

Im Bereich der Computertomographie (CT) existiert eine Reihe von Anwendungen, wie zum Beispiel Microoder Dental-CT, die eine längere Datenakquisitionszeit aufweisen. Entsprechend nimmt die Frage der Bewegungskorrektur eine wichtige Stellung ein, da sich z. B. bei der Dental-CT Patientenbewegungen nicht vollständig vermeiden lassen. Die gängigste Methode der Bewegungskorrektur ist die Data-Drive...
