(Hospital Clinicas, Univ São Paulo, 2014-01-01)
OBJECTIVES: the purpose of our study was to report the results of the implementation of computed tomography colonography in a university hospital setting serving a Brazilian population at high risk of colorectal cancer.METHODS: ...
Post expansion evaluation of the midpalatal suture in children submitted to rapid palatal expansion: A CT study
(2006-12-01)
The aim of this prospective study was to evalute the midpalatal suture in children submitted to rapid palatal expansion, at the end of the retention stage, with CT scans. The sample was comprised of 17 children aged between ...
Cone-beam computed tomography analysis of the apical third of curved roots after mechanical preparation with different automated systems
(2009-12-01)
The present study evaluated by cone-beam computed tomography (CBCT) the apical canal transportation and centralizing ability of different automated systems after root canal preparation. The mesiobuccal canals of maxillary ...
Dosimetry and cost of imaging osseointegrated implants with film-based and computed tomography
(1997-12-01)
Thermoluminescent dosimeters were used to measure radiation doses at craniofacial sites in a tissue-equivalent phantom during film-based multidirectional tomography with the Tomax Ultrascan (Incubation Industries, Ivyland, ...
High-Resolution Computed Tomography in the Diagnosis of Diffuse Parenchymal Lung Diseases: Is it Possible to Improve Radiologist's Performance?
(Lippincott Williams & Wilkins, 2016)
Objective The aims of this study were to assess the concordance between high-resolution computed tomography (HRCT) diagnostic hypotheses (DH) and final diagnosis in patients with diffuse lung disease and to evaluate whether ...
Avaliação da inclinação do incisivo inferior através da tomografia computadorizada
(2008-12-01)
Introduction: Orthodontics has always used lateral cephalometric radiographs (LC) as the main examination in the orthodontic diagnosis and treatment plan. The determination of incisor position is part of most cephalometric ...
The large vestibular aqueduct syndrome: A cause of neurosensory dysacusia
(2008-09-11)
Background: The large vestibular aqueduct syndrome (LVAS) is characterized by the enlargement of the vestibular aqueduct associated with sensorioneural hearing loss. The level of hearing loss varies and may be fluctuant, ...
Periodontal effects of rapid maxillary expansion with tooth-tissue-borne and tooth-borne expanders: A computed tomography evaluation
(2006-06-01)
Introduction: The force delivered during rapid maxillary expansion (RME) produces areas of compression on the periodontal ligament of the supporting teeth. The resulting alveolar bone resorption can lead to unwanted tooth ...
Transverse effects after surgically assisted rapid maxillary expansion in the midpalatal suture using computed tomography
(Lippincott Williams & Wilkins, 2008-03-01)
Surgically assisted rapid maxillary expansion is the treatment of choice for correcting maxillary transverse deficiency in adults. Traditionally, the appliance for expansion is tooth-borne and tissue-tooth-borne devices ...
Identification of rounded atelectasis in workers exposed to asbestos by contrast helical computed tomography
(Assoc Bras Divulg Cientifica, 2003-10-01)
Rounded atelectasis (RA) is a benign and unusual form of subpleural lung collapse that has been described mostly in asbestos-exposed workers. This form of atelectasis manifests as a lung nodule and can be confused with ...
