Importance of chest HRCT in the diagnostic evaluation of fibrosing interstitial...
Torres,Pedro Paulo Teixeira e Silva; Rabahi,Marcelo Fouad; Moreira,Maria Auxiliadora do Carmo; Escuissato,Dante Luiz; Meirelles,Gustavo de Souza PortesABSTRACT Many conditions result in chronic interstitial lung disease (ILD), being classified as fibrosing ILDs, including idiopathic pulmonary fibrosis, connective tissue diseases, sarcoidosis, and fibrotic hypersensitivity pneumonitis. HRCT plays an important role in the clinical evaluation of fibrosing ILDs. Current treatment perspectives are encouraging and reinforce the need for HRCT scans of adequate techn...
High-resolution computed tomography findings in eight patients with hantavirus ...
Barbosa,Diego de Lacerda; Hochhegger,Bruno; Souza Jr.,Arthur Soares; Zanetti,Gláucia; Escuissato,Dante Luiz; Meirelles,Gustavo de Souza PortesAbstract Objective: The purpose of this study was to describe the high-resolution computed tomography (HRCT) findings in patients with hantavirus pulmonary syndrome (HPS). Materials and Methods: We retrospectively reviewed HRCT findings from eight cases of HPS. All patients were men, aged 19-70 (mean, 41.7) years. Diagnoses were established by serological test (enzyme-linked immunosorbent assay) in all patients...
Metastatic pulmonary calcification: high-resolution computed tomography finding...
Belém,Luciana Camara; Souza,Carolina A.; Souza Jr.,Arthur Soares; Escuissato,Dante Luiz; Hochhegger,Bruno; Nobre,Luiz Felipe; Rodrigues,Rosana SouzaAbstract Objective: The aim of this study was to evaluate the high-resolution computed tomography (HRCT) findings in patients diagnosed with metastatic pulmonary calcification (MPC). Materials and Methods: We retrospectively reviewed the HRCT findings from 23 cases of MPC [14 men, 9 women; mean age, 54.3 (range, 26-89) years]. The patients were examined between 2000 and 2014 in nine tertiary hospitals in Brazil...
Laryngotracheobronchial papillomatosis: chest CT findings
Fortes,Helena Ribeiro; Ranke,Felipe Mussi von; Escuissato,Dante Luiz; Araujo Neto,Cesar Augusto; Zanetti,Gláucia; Hochhegger,Bruno; Irion,Klaus LoureiroABSTRACT To evaluate the findings on chest CTs in 16 patients (8 men and 8 women) with laryngotracheobronchial papillomatosis. Methods: This was a retrospective study involving patients ranging from 2 to 72 years of age. The evaluation of the CT scans was independently performed by two observers, and discordant results were resolved by consensus. The inclusion criteria were presence of abnormalities on the CT s...
Pulmonary magnetic resonance imaging is similar to chest tomography in detectin...
Müller,Carolina de Souza; Warszawiak,Danny; Paiva,Eduardo dos Santos; Escuissato,Dante LuizAbstract Interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) are prevalent complications of systemic sclerosis (SSc) and are currently the leading causes of death related to the disease. The accurate recognition of these conditions is therefore of utmost importance for patient management. A study was carried out with 24 SSc patients being followed at the Rheumatology Department of the Hosp...
Can chest high-resolution computed tomography findings diagnose pulmonary alveo...
Francisco,Flávia Angélica Ferreira; Rodrigues,Rosana Souza; Barreto,Miriam Menna; Escuissato,Dante Luiz; Araujo Neto,Cesar AugustoAbstract Objective: The present study was aimed at retrospectively reviewing high-resolution computed tomography (HRCT) findings in patients with pulmonary alveolar microlithiasis in order to evaluate the frequency of tomographic findings and their distribution in the lung parenchyma. Materials and Methods: Thirteen patients (9 females and 4 males; age, 9 to 59 years; mean age, 34.5 years) were included in the ...
Chest magnetic resonance imaging: a protocol suggestion
Hochhegger,Bruno; Souza,Vinícius Valério Silveira de; Marchiori,Edson; Irion,Klaus Loureiro; Souza Jr.,Arthur Soares; Elias Junior,JorgeAbstract In the recent years, with the development of ultrafast sequences, magnetic resonance imaging (MRI) has been established as a valuable diagnostic modality in body imaging. Because of improvements in speed and image quality, MRI is now ready for routine clinical use also in the study of pulmonary diseases. The main advantage of MRI of the lungs is its unique combination of morphological and functional as...
Organizing pneumonia: chest HRCT findings
Faria,Igor Murad; Zanetti,Gláucia; Barreto,Miriam Menna; Rodrigues,Rosana Souza; Araujo-Neto,Cesar Augusto; Silva,Jorge Luiz Pereira eOBJECTIVE: To determine the frequency of HRCT findings and their distribution in the lung parenchyma of patients with organizing pneumonia. METHODS: This was a retrospective review of the HRCT scans of 36 adult patients (26 females and 10 males) with biopsy-proven organizing pneumonia. The patients were between 19 and 82 years of age (mean age, 56.2 years). The HRCT images were evaluated by two independent obse...
Cocaine-induced pulmonary changes: HRCT findings
Almeida,Renata Rocha de; Zanetti,Gláucia; Souza Jr.,Arthur Soares; Souza,Luciana Soares de; Silva,Jorge Luiz Pereira e; Escuissato,Dante LuizAbstractObjective: To evaluate HRCT scans of the chest in 22 patients with cocaine-induced pulmonary disease.Methods: We included patients between 19 and 52 years of age. The HRCT scans were evaluated by two radiologists independently, discordant results being resolved by consensus. The inclusion criterion was an HRCT scan showing abnormalities that were temporally related to cocaine use, with no other apparent...
Adrenoleucodistrofia ligada ao X: correlação entre o escore de Loes e parâmetro...
Ono,Sergio Eiji; Carvalho Neto,Arnolfo de; Gasparetto,Emerson Leandro; Coelho,Luiz Otávio de Mattos; Escuissato,Dante Luiz; Bonfim,Carmem Maria SalesObjetivo: Avaliar a correlação dos parâmetros do tensor de difusão com o escore de Loes e se os parâmetros do tensor de difusão poderiam indicar alterações estruturais precoces. Materiais e Métodos: As medidas do tensor de difusão foram obtidas em 30 exames de 14 pacientes com adrenoleucodistrofia ligada ao X e foram correlacionadas com o escore de Loes. Um grupo controle de 28 pacientes masculinos foi avaliado...
