Tomografia computadorizada sem contraste intravenoso no abdome agudo: Directory of Open Access Journals Sweden. The use of unenhanced computed tomography has been frequently recommended for the initial assessment of patients with clinical suspicion of acute abdomen instead of other diagnostic methods.
The authors present a review of the literature on the main aspects, advantages, limitations and efficacy of unenhanced computed tomography for the diagnosis of acute appendicitis, renal colic, diverticulitis, acute pancreatitis, primary epiploic appendicitis, pneumoperitoneum and small bowel obstruction. The advantages and limitations of this technique are also discussed.

Cento e sessenta dentes foram selecionados e divididos em quatro grupos de acordo com o material de preenchimento sem guta-percha, com guta-perch Aspectos na tomografia computadorizada. Trauma is nowadays one of the most common causes of death and traumatic thoracic lesions are important agravant to trauma patients.
In this work the aspects of computed tomography from cases of thoracic "En que consiste la patristica yahoo dating" were studied. Acute appendicitis is the most important cause of abdominal pain requiring surgical intervention in the Western world.
The early diagnosis of this disease is of paramount relevance for minimizing its morbidity. Diagnostic difficulty is higher in children, the elderly, and women in childbearing age. The main imaging methods for evaluation of acute appendicitis are ultrasound and computed tomography. The present study is aimed at describing the disease physiopathology, commenting main computed tomography technical aspects, demonstrating and illustrating tomographic findings, and describing main differential diagnoses.
Os resultados obtidos foram confrontados com os descritos na literatura. They presented calcifications in basal ganglia, dentate nucleus, subcortical region and semioval center, due to alteration in calcium metabolism or due to senile relative hypoxemic state.
The image pattern was not strictly related with etiology, although some differences in dystrophic senile calcifications the only one present in semioval center and absent in subcortical region. CT is an easy exam, has maximum sensitivity and allows diagnosis, contributing to early treatment of many etiologies of Fahr's syndrome.
To identify the main tomographic findings of retrofenestral otosclerosis. A prospective and multicentric study using computed tomography CT of the temporal bone in 54 patients with a clinical and surgical diagnosis of otosclerosis. A tomographic analysis has been performed to evaluate the
En que consiste la patristica yahoo dating of CT scans in diagnosing retrofenestral otosclerosis, verifying the sites of predilection for otosclerotic lesions.
In this study, 22 patients undergone CT scans of temporal bones have been included in order to investigate other otologic diseases and have constituted the control group.
The tomographic findings were mostly bilateral and the retrofenestral focus more prevalent was the pericochlear focus. The CT scan was useful in the identification of the retrofenestral focuses. The evidence of this focuses and the presence of the endosteal involvement of the cochlea can suggest a higher activity of the disease.
Foi realizado um estudo descritivo sem seguimento no qual foram comparadas as estruturas da orelha interna da ovelha com as dos humanos. Studies about the use of sheep in surgical training and experimental otologic surgery are rare. This study intends to contribute to the knowledge on this field. To study sheep inner ear structures using computerized tomography and serial cross-sections to collect more accurate morphometric data to compare sheep and human ears.
This descriptive study compared the inner structures of sheep and human ears. Mean measures for sheep and human ears were found to be similar in this morphological study. What is the real role of the equilibrium phase in abdominal computed tomography? To evaluate the role of the equilibrium phase in abdominal computed tomography.
A retrospective, cross-sectional, observational study reviewed consecutive contrast-enhanced abdominal computed tomography images acquired in a three-month period, for different clinical indications. For each study, two reports were issued - one based on the initial analysis of non-contrast-enhanced, arterial and portal phases only first analysis, and a second reading of these phases added to the equilibrium phase second analysis.
At the end of both readings, differences between primary and secondary diagnoses were pointed out and recorded, in order to measure the impact of suppressing the equilibrium phase on the clinical outcome for each of the patients.
The extension of the exact Fisher. Todos os pacientes realizaram tomografia computadorizada antes da cirurgia. To quantify bone formation within autogenous bone grafts and autogenous bone grafts in combination with platelet-rich plasma obtained either from aphaeresis or centrifugation using computed tomography.
This prospective, double-blind study was conducted in 34 male and female adult patients mean age of 28 years and 8 months, with either unilateral or bilateral pneumatization of the maxillary sinuses, requiring bone graft for dental.
Os exames foram revisados por dois radiologistas, que estabeleceram os achados por consenso. To describe the high-resolution computed tomography findings in the lung of patients with systemic sclerosis, independently of the respiratory symptoms. Seventy-three high-resolution computed tomography scans of 44 patients with clinical diagnosis of systemic sclerosis were reviewed and defined by the consensus of two radiologists.
Abnormalities were seen in The most frequent findings were reticular pattern The lesions were predominantly located in the basal The advent of computed tomography permitted a much more precise evaluation of tumor localization, thus facilitating presurgical staging. The objective of this study was to evaluate the interobserver agreement on the analysis of computed tomography scans of 15 patients with juvenile nasopharyngeal angiofibroma, regarding assessment of tumor extension to sites of high recurrence rate.
All patients were male and had a mean age of The results of the interobserver agreement

We concluded that there is a very good interobserver agreement on the evaluation of the established. This study aimed to use high-resolution computed tomography scans of the chest to characterize the principal alterations occurring in cases of hydrostatic pulmonary edema.
A retrospective analysis was made of the tomography scans of 15 patients presenting clinical profiles of hydrostatic pulmonary edema.
The cases were divided into five groups by etiology: Aspectos da tomografia computadorizada no linfoma em pacientes abaixo de 20 anos de idade Computed tomography findings in patients less than 20 years old with lymphoma. To describe the general findings of lymphoma and their histological patterns in patients less than 20 years old. Twenty-two cases 16 male and 6 female, mean age Traumatic lesions of the lung are common findings in patients with thoracic trauma.
These lesions are increasingly diagnosed using computed tomography, mostly due to the fast acquisition time helical techniques that allow evaluation of critically ill patients and an efficient therapeutic management. The authors studied patients with thoracic trauma submitted to computed tomography that demonstrated lung contusions, atelectasies, lacerations and hematomas.
Lung contusions were the most frequent lesions. Most temporal bone fractures result from high-energy blunt head trauma, and are frequently related to other skull fractures or to polytrauma. Fractures and displacements of ossicular chain in the middle ear represent some of the main complications of temporal bone injury, and hence they will be more deeply approached in the present article.
Other types of injuries include labyrinthine fractures, dural fistula, facial nerve paralysis and extension into the carotid canal. Computed tomography plays a fundamental role in the initial evaluation of polytrauma patients, as it can help to identify important structural injuries that may lead to severe complications such as sensorineural hearing loss, conductive hearing loss, dizziness
