We compared high-resolution computed tomography (HRCT) with chest radiography (CR) to determine if there is any advantage to using HRCT in the diagnosis of community-acquired pneumonia (CAP). Simultaneously obtained chest radiographs were compared with HRCT scans for 47 patients with clinical symptoms and signs suspicious for CAP, HRCT identified all 18 CAP cases (38.3%) apparent on radiographs...

BACKGROUND The 2011 idiopathic pulmonary fibrosis (IPF) guidelines are based on the diagnosis of IPF using only high-resolution computed tomography (HRCT). However, few studies have thus far reviewed the usefulness of the HRCT scoring system based on the grading scale provided in the guidelines. We retrospectively studied 98 patients with respect to assess the prognostic value of changes in HRC...

UNLABELLED BACKGROUND Chest-X-ray has several limitations in detecting the extent of pulmonary disease in sarcoidosis. It might not reflect the degree of pulmonary involvement in patients with sarcoidosis when compared to computed tomography of the thorax. We aimed to investigate the HRCT findings of pulmonary sarcoidosis and to find out the existence of possible relations between HRCT findi...

High-resolution computed tomography (HRCT) imaging has a central role in the diagnosis of interstitial lung diseases, particularly in the evaluation of patients with suspected idiopathic pulmonary fibrosis (IPF). In approximately half of cases, HRCT scans are sufficient to allow a confident IPF diagnosis. Advances in HRCT scanning and interpretation have facilitated improved accuracy for use in...

Ocular sarcoidosis is frequent in Japan, but in many cases the condition remains undiagnosed in patients with suspected ocular sarcoidosis. Bronchoalveolar lavage (BAL) was performed in order to study the clinical implications of lymphocytosis of BAL fluid in such patients with characteristic ocular manifestations. The subjects included in this study were 39 patients with suspected ocular sarco...

Background and Objective: Measurement of inflammatory markers and lactate dehydrogenase (LDH) may contribute to the evaluation of lung involvement severity. This study aimed to evaluate relationship between severity of primary lung involvement with highest level of erythrocyte sedimentation rate (ESR) and LDH in patients with COVID-19. Materials and Methods: This descriptive-analytical study w...

BACKGROUND High resolution computed tomography (HRCT) has an important diagnostic role in idiopathic interstitial pneumonia (IIP). We hypothesised that the HRCT appearance would have an impact on survival in patients with IIP. METHODS HRCT scans from patients with histological usual interstitial pneumonia (UIP; n=73) or histological non-specific interstitial pneumonia (NSIP; n=23) were charac...

AIM To characterize and compare total lung capacity (TLC) measured by plethysmography with high-resolution computed tomography (HRCT), and to identify variables that predict the difference between the two modalities. METHODS Fifty-nine consecutive patients referred for the evaluation of COPD were retrospectively reviewed. Patients underwent full pulmonary function testing and HRCT within 3 mo...

Some patients with idiopathic pulmonary fibrosis (IPF) do not have honeycombing on high-resolution computed tomography (HRCT) at their initial evaluation. The clinical course and sequential changes in HRCT findings in these patients are not fully understood. We reviewed the cases of 43 patients with IPF without honeycombing on initial HRCT from institutions throughout Japan. All patients were d...

The purpose of this study is to assess the utility of the chest high-resolution computed tomography (HRCT) scan for estimating the severity of haemoptysis, localize the bleeding site and to determine a cause of the bleeding. We reviewed 80 consecutive patients who were admitted to a respiratory intensive care unit (RICU) for haemoptysis and who underwent unenhanced HRCT scanning and fibre-optic...
