This research proposes to evaluate and implement a solution for metal artifact reduc- tion in computed tomography, this one aiming to meet a demand from the prototyping laboratory of the Núcleo de Tecnologias Estratégicas em Saúde (Nutes) da Univer- sidade Estadual da Paraíba, where impressions of biomodels are made for surgical planning. The CT affected by metal artifacts need to be corrected prior to the printing process, this manual intervention implies excessive delay for delivery of the biomodels. The development of the proposed solution is based on the sinogram correction method which according to Mouton et al (2013) and Gjesteby (2016) is the most utilized method for reducing metal artifacts and makes uses of linear interpolation to correction the cor- rupted data. In order to validate the preference for linear interpolation in the state of the art, others interpolative techniques were implemented and evaluated; Fist through simulations and then by a form for qualitative evaluation, upon which statistical tests were applied. The results obtained confirm the use of interpolation as the best option for the reconstruction of data corrupted by metallic artifacts.
Esta pesquisa se propõe a avaliar e implementar uma solução para redução de artefatos metálicos em tomografias computadorizadas, solução esta que visa atender uma demanda do laboratório de prototipagem do Núcleo de Tecnologias Estratégicas em Saúde (Nutes) da Universidade Estadual da Paraíba, onde são realizadas impressões de biomodelos para planejamentos cirúrgicos. As tomografias afetadas por artefatos metálicos necessitam de correção antes do processo de impressão, esta intervenção realizada de forma manual implica em demora excessiva para entrega dos biomodelos. O desenvolvimento da solução proposta baseia-se no método de correção de sinograma que, de acordo com Mouton et al (2013) e Gjesteby (2016), é o método mais difundido para redução de artefatos metálicos e faz uso da técnica de interpolação linear para correção dos dados corrompidos. Objetivando validar a preferência pelo uso da interpolação linear no estado da arte, foram implementadas outras técnicas interpolativas as quais foram submetidas a avaliação; Primeiro por meio de simulações e depois via fomulário para avaliação qualitativa, na qual foram aplicados testes estatísticos. Os resultados obtidos ratificam o uso da interpolação linear como melhor opção para reconstrução de dados corrompidos pelos artefatos metálicos.

Texto completoComputed tomography is an important tool to determinate the diagnosis, treatment and follow up malignant lesions of the maxillomandibular complex. In many cases, it is the election exam to all of these purposes. One problem with CT is the artifacts that appear in the presence of metallic restorations, implants and metallic fixation screws or plates. These artifacts lead to misinterpretations of the images, making difficult to visualize lesions in these areas. The aim of this research was to evaluate CT images with different sections (axial and coronal) e to determine if the type of section can minimize the problem of dental metallic artifacts. Two calibrate examiners (oral and maxillofacial radiologists) analyzed 72 images (36 in axial slices and 36 in coronal slices) and graduate which images were best viewed. The results attested that there were no significant differences between axial and coronal images to reach the diagnosis in the presence of dental metallic artifacts, and there were a good concordance with both examiners. We conclude that the presence of dental metallic artifacts wasnt sufficient to disturb the precise location neoplasm of the soft tissue. It wasnt detected any dental metallic interference possible to misdiagnosis neither on axial images nor on coronal images. Coronal images presented a higher interference when comparing with axial images.

Texto completoObjective: The objective was to evaluate the influence of dental metallic artefacts on linear measurements (height and thickness) performed in parassagital sections at the alveolar ridge at the mentual foramen region using multislice and cone-beam computed tomography techniques. Materials and Methods: Ten dried human mandibles were scanned twice by each technique, with and without dental metallic artefacts. Metallic restorations were placed at the top of the alveolar ridge, adjacent and coronary to the mental foramen region for the second scanning, in order to simulate dental metallic artefacts. Parassagital images were obtained and linear measurements were performed using the Imaging Studio ® software, by a single examiner previously trained and calibrated. The observer also analyzed if the presence of the artefacts could jeopardize the identification of anatomic structures at the image. All mandibles were analyzed at both the right and the left mental foramen regions. Results: For the multislice technique, dental metallic artefacts produced an increase of 5% in bone thickness and a reduction of 6% in bone height, although these differences were not statistically significant (p > 0.05). With respect to the cone-beam technique, dental metallic artefacts produced an increase of 6% in bone thickness and a reduction of 0.68% in bone height. No significant differences (p > 0.05) were observed when comparing measurements performed with and without metallic artefacts. At the images with artefacts, the alveolar bone identification was jeopardized at both techniques. Conclusion: the presence of dental metallic artefacts did not alter the linear measurements obtained with both techniques, although its presence made the location of the alveolar bone crest more difficult.

Texto completoObjective: The objective of this study was to evaluate the influence of metallic artifacts in CBCT (Cone beam computed tomography) images, caused by dental titanium implants, at adjacent periodontal structures. Materials and Methods: 23 patients were submitted a CBCT examination before and after the implant placement. Thickness Measurements of buccal cortical were performed by a calibrated observer (ICC=0.95), at parassagital cross-sections of previously obtained images. The frequency of influence level (mild, moderate, severe) of the artifact was calculated for horizontal distance of the implant, buccal cortical thickness and vertical distance of the buccal alveolar crest. Results: 5 patients were excluded, and 18 selected, 24 unitary implants cases at posterior mandible were examined, 24 mesial test teeth (MTT) and 17 Distal test teeth (DTT) from the implants. There was an association between the vertical distance of the buccal alveolar crest and the impossibility to measure the thickness of buccal cortical for MTT and DTT (p<0.05 for both). There was no association between the thickness of buccal cortical and horizontal distance for the artifacts level of influence (p>0.05 for both). There was association between horizontal distance and the level of the artifact influence at any periodontal structure, for the sum of MTT and DTT (p<0.05). Conclusion: the metallic artifacts caused by dental implants can influence the CBCT image interpretation at periodontal adjacent sites, and the level of the influence depends on the horizontal distance of the dental implant at any periodontal structures, and the vertical distance from the buccal alveolar crest.
