1. Endobronchial ultrasound: a minimally invasive technology to assist diagnosis of thoracic diseases
RESUMO A ultrassonografia endobrônquica é uma técnica minimamente invasiva que associa simultaneamente broncoscopia à ultrassonografia, com a finalidade de visualizar nódulos ou massas pulmonares, paredes das vias aéreas, e estruturas ao redor de toda a árvore traqueobrônquica. A ultrassonografia endobrônquica foi incorporada à prática clínica em

2. Early and Accurate Model of Malignant Lung Nodule Detection System with Less False Positives
ABSTRACT The objective of this work is to identify the malignant lung nodules accurately and early with less false positives. ‘Nodule’ is the 3mm to 30mm diameter size tissue clusters present inside the lung parenchyma region. Segmenting such a small nodules from consecutive CT scan slices are a challenging task. In our work Auto-seed clustering based se

3. Septic pulmonary embolism caused by a Klebsiella pneumoniae liver abscess: clinical characteristics, imaging findings, and clinical courses
OBJECTIVES: Septic pulmonary embolism caused by a Klebsiella (K.) pneumoniae liver abscess is rare but can cause considerable morbidity and mortality. However, clinical information regarding this condition is limited. This study was conducted to elucidate the full disease spectrum to improve its diagnosis and treatment. METHOD: We reviewed the clinical cha

4. DETECÇÃO DE NÓDULOS PULMONARES PEQUENOS USANDO MODELO DE MISTURA GAUSSIANA E MATRIZ HESSIANA / DETECTION OF SMALL LUNG NODULES USING MODEL OF GAUSSIAN MIXTURE AND THE HESSIAN MATRIX
Dentre os outros tipos de câncer, o câncer de pulmão se destaca por apresentar a maior incidência e a maior taxa de mortalidade de todos, além de uma das menores taxas de sobrevida após o diagnóstico (cinco anos em média), fato este decorrido principalmente pela detecção e, conseqüentemente, tratamento tardio. Para auxiliar o especialista na busca

5. Avaliação do vetor retroviral bicistrônico Codificador de endostatina e interleucina-2 Para utilização em terapia gênica anti-tumoral. / Evaluation of retroviral vector encoding bicistônico of endostatin and interleukin-2 for use in anti-tumor gene therapy
Gene therapy has been used in preclinical studies and clinical trials in order to assuage or cure a disease. Retroviral vectors are tools for gene transfer are widely used. Bicistronic vectors are attractive alternatives for treatment of complex disease. Endostatin (ES), the C-terminal fragment of collagen XVIII, is a potent angiogenesis inhibitor. At presen

6. SEGMENTAÇÃO AUTOMÁTICA DE NÓDULOS PULMONARES COM GROWING NEURAL GAS E MÁQUINA DE VETORES DE SUPORTE / AUTOMATIC SEGMENTATION OF PULMONARY NODULES WITH GROWING NEURAL GAS VECTOR MACHINE AND SUPPORT
O câncer de pulmão ainda é um dos mais incidentes em todo mundo. Seu diagnóstico é de difícil realização, devido as suas características morfológicas iniciais não estarem bem definidas e também por causa da sua localização em relação ao pulmão. É geralmente detectado tardiamente, que tem como conseqüência uma alta taxa de letalidade. Dian

7. SEGMENTAÇÃO MULTICRITÉRIO PARA DETECÇÃO DE NÓDULOS PULMONARES EM IMAGENS DE TOMOGRAFIA COMPUTADORIZADA / MULTICRITERION SEGMENTATION FOR LUNG NODULE DETECTION IN COMPUTED TOMOGRAPHY
This study proposes a novel segmentation algorithm for lung nodules detection in thorax computed tomography (CT). In order to decide, at each iteration, whether two adjacent objects should be merged or not, a region growing procedure calculates a heterogeneity growth based on multiple criteria. However, segmentation algorithm depends on some parameters which

8. METHODOLOGY FOR AUTOMATIC DETENTION OF PULMONARY NODULES / METODOLOGIA PARA DETECÇÃO AUTOMÁTICA DE NÓDULOS PULMONARES
O câncer de pulmão é uma enfermidade com prevalência significativa em diversos países no mundo todo. O difícil tratamento e a progressão rápida da doença fazem com que os índices de mortalidade das pessoas acometidas por este mal sejam muito altos. O principal fator contribuinte para um tratamento de sucesso, entretanto, é o diagnóstico precoce.

9. Infection with the Mycobacterium avium complex in patients without predisposing conditons: a case report and literature review
Nontuberculous Mycobacteria (NTM), especially Mycobacterium avium-intracellulare complex (MAC), has been considered responsible for human disease, especially in HIV patients. Nevertheless, it has been diagnosed in immunocompetent elderly men, frequently with previous pulmonary disease: chronic obstructive lung disease (COPD), complications of tuberculosis, p

10. Identification of rounded atelectasis in workers exposed to asbestos by contrast helical computed tomography
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 bronchogenic carcinoma upon conventional radiologic examination. The objective of the present study was to evaluate the variation in contrast

11. Eosinophilic granuloma of the lung presenting as a solitary pulmonary nodule.
A symptomless 58 year old man had an eosinophilic granuloma of the lung that presented as a solitary pulmonary nodule rather than the usual diffuse reticulonodular shadow on the chest radiograph. Only one previous case presenting in this way has been described.

12. A solitary amyloid nodule in the lung
Solitary primary amyloid nodule of the lung is rare. Only eight cases have been reported. Our patient was a 66-year-old retired furnaceman who had an asymptomatic, smooth, round shadow in the right lower lobe, discovered accidentally on routine chest radiography. Right lower lobectomy was performed and a firm round nodule was found in the lateral basal segme
