1. Effect of Different Dimensions of Test Samples on the Volumetric Change Assessment Of Endodontic Materials
Resumo Novas metodologias utilizando micro-CT são propostas para avaliar a solubilidade além de alterações dimensionais e morfológicas em materiais endodônticos. No entanto, não há padronização nos métodos. O objetivo deste estudo foi avaliar o efeito de diferentes dimensões de corpos de prova na avaliação da alteração volumétrica de diferen

2. Assessment of remnant liver function and volume after selective ligation of portal vein and hepatic artery in a rat model
Abstract Purpose: To evaluate liver regeneration after selective ligation of portal vein and hepatic artery by 3D Computed Tomography in an experimental model. Methods: Sixteen Wistar rats were randomized into four equal groups: Group I- control (sham), Group II- isolated selective ligation of the hepatic artery, Group III- isolated selective ligation of t

3. Solubility, Porosity, Dimensional and Volumetric Change of Endodontic Sealers
Resumo O objetivo deste estudo foi avaliar propriedades físicas de cimentos endodônticos (AH Plus, MTA Fillapex e Endofill), por meio de testes convencionais e micro-CT. A estabilidade dimensional foi avaliada após imersão dos materiais em água destilada por 30 dias. A solubilidade e a alteração volumétrica dos materiais foram avaliadas após 7 e 30

4. Multimodal quantitative magnetic resonance imaging analysis with individualized postprocessing in patients with drug-resistant focal epilepsy and conventional visual inspection negative for epileptogenic lesions
OBJECTIVES: Approximately one-third of candidates for epilepsy surgery have no visible abnormalities on conventional magnetic resonance imaging. This is extremely discouraging, as these patients have a less favorable prognosis. We aimed to evaluate the utility of quantitative magnetic resonance imaging in patients with drug-resistant neocortical focal epile

5. Volumetric reconstruction and determination of minimum crosssectional area of the pharynx in patients with cleft lip and palate: comparison between two different softwares
Abstract Objective: The aim of this study was to assess the accuracy of volumetric reconstruction of the pharynx by comparing the volume and minimum crosssectional area (mCSA) determined with open-source applications (ITK-Snap, www.itksnap.org ; SlicerCMF) and commercial software (Dolphin3D, 11.8, Dolphin Imaging & Management Solutions, Chatsworth, CA, USA)

6. The thickness of posterior cortical areas is related to executive dysfunction in Alzheimer's disease
OBJECTIVE: To establish whether alterations of brain structures in Alzheimer's disease are associated with executive dysfunction. METHODS: Nineteen patients with Alzheimer's disease and 22 older control subjects underwent a comprehensive evaluation. The clock drawing test, digit span test, executive motor function test, Behavioral Assessment of the Dysexe

7. Structural changes of dilated pelvic ureters in adults
PURPOSE: To perform a quantitative assessment of different types of pelvic ureter tissues with chronic dilation in adults, using stereological methods. METHODS: We analyzed fragments of dilated pelvic ureters obtained from 6 patients aged between 35 and 67 years (mean, 46 years) who underwent ureteral reimplantation surgery for different reasons. The obstru

8. Avaliação volumétrica da fenda alveolar por meio de tomografia computadorizada por feixe cônico (TCFC) em pacientes com fissura labiopalatina / Volumetric assessement of the alveolar cleft using Cone Beam Computerized Tomography (CBCT) in patients with cleft lip and palate
A reabilitação dos pacientes com fissura de lábio e palato teve significativa evolução nas últimas décadas, sendo o desenvolvimento do enxerto ósseo alveolar muito importante para este avanço. É um procedimento que requer atenção rigorosa aos detalhes, por esta razão os exames de imagem são de grande auxílio. As Tomografias Computadorizadas en

9. Correlação entre atrofia hipocampal e déficit de memória em pacientes com epilepsia de lobo temporal mesial / Correlation between hippocampal atrophy and memory deficits in patients with mesial temporal lobe epilepsy
Mesial Temporal Lobe Epilepsy (MTLE) is the most common focal epilepsy in adults and is usually associated with hippocampal atrophy (HA) which is recognized by highresolution magnetic resonance imaging (MRI). It consists of a syndrome that is often refractory to clinical treatment and patients may have memory deficits due to hippocampal system damage, howeve

10. Oral conditions and Streptococcus mutans isolation in patients undergoing bariatric surgery / CondiÃÃes bucais e isolamento de Streptococcus mutans em pacientes submetidos à cirurgia bariÃtrica
Introduction: Obesity is associated with oral diseases by promoting inflammatory processes and because of the fact that obese patients often eat cariogenic foods and use drugs capable of inducing salivary alterations. Bariatric surgery, surgical means of treating morbid obesity and obesity associated to co-morbidities, aims to change the volumetric capacity

11. Computed tomography assessment of lung structure in patients undergoing cardiac surgery with cardiopulmonary bypass
Hypoxemia is a frequent complication after coronary artery bypass graft (CABG) with cardiopulmonary bypass (CPB), usually attributed to atelectasis. Using computed tomography (CT), we investigated postoperative pulmonary alterations and their impact on blood oxygenation. Eighteen non-hypoxemic patients (15 men and 3 women) with normal cardiac function schedu

12. Avaliação volumétrica de defeitos ósseos em fissuras de rebordo alveolar e palato duro por meio da 3D-TC multislice e feixe cônico / Volumetric assessment of hard palate and alveolar cleft using multislice and cone beam 3DCT
As fissuras de rebordo alveolar e palato duro estão entre as malformações mais frequentes do corpo humano, podendo causar extensas deformidades ósseas faciais, com implicações biopsíquico-sociais marcantes. A avaliação da extensão desses defeitos ósseos, através de exames por imagem, tem sido feita com o objetivo de diagnosticar e planejar a tera
