1. Comparison of imaging modalities for detection of residual fragments and prediction of stone related events following percutaneous nephrolitotomy
Introduction Achieving stone free status (SFS) is the goal of stone surgery. In this study it is aimed to compare effectiveness of unenhanced helical computerized tomography (UHCT), KUB and ultrasonography (US) for detection of residual RFs and predicition of stone releated events following percutaneous nephrolitotomy (PNL). Materials and Methods Patients u

2. Estudo da prevalência da posição vestíbulo-lingual do canal mandibular por meio da tomografia computadorizada helicoidal / Prevalency study of the vestibulo-lingual position from the mandibular canal by helical computerized tomography
The course of the mandibles canal is oblique with posterior-anterior direction, it comes close to the medial cortical alveolar bony, until reaching the mesial face of the first inferior molar, starting from this area, it approaches of the lateral cortical alveolar bony until reaching the forame mentual. Radiographically, the manbible´s canal comes, as a rad

3. Doses e risco de radiação em estudo tomográfico computadorizado do tórax com tecnologia de quatro cortes
The computerized tomography (CT) is an important method for studying chest pathologies to provide its morphological and functional analysis and to allow a specific therapeutic approach of signs or symptoms resulting from diseases. Since CT uses ionizing radiation, it should be considered that a precise balance between risks and benefits must be achieved in o

4. Interobserver evaluation of the virtual sinuscopy application compared with the images obtained by means of helical computerized tomography in sinusal compromise. / "Avaliação inter-observador da aplicação da sinuscopia virtual, comparada com as imagens obtidas por meio da tomografia computadorizada helicoidal, nos comprometimentos sinusais"
Objetivo: Comparar as imagens obtidas por meio da sinuscopia virtual com aquelas adquiridas por meio da tomografia computadorizada helicoidal, quando da interpretação dos comprometimentos sinusais, considerando as opiniões dos médicos otorrinolaringologistas e radiologistas odontológicos, com a finalidade de validação do método da sinuscopia virtual.

5. Prediction of differential creatinine clearance in chronically obstructed kidneys by non-contrast helical computerized tomography
PURPOSE: We investigate the use of non-contrast helical computerized tomography (NCHCT) in the measurement of differential renal parenchymal volume as a surrogate for differential creatinine clearance (CrCl) for unilateral chronically obstructed kidney. MATERIALS AND METHODS: Patients with unilateral chronically obstructed kidneys with normal contralateral k

6. Visualização e analise do deslocamento imiscivel e instavel em meio poroso consolidado
The main objective of this study is to investigate, at laboratory scale, the influence of both displacement velocity and mobility ratio on the relative permeability and geometry of two phase immiscible flow, in a naturally consolidated porous medium, in the presence of conate water saturation. The displacement experiments were carried out in cylindrical core
