Computed tomography with normal chest radiograph in tuberculous infection.

Computed tomography with normal chest radiograph in tuberculous infection.

Children with primary tuberculosis infection without disease must be identified and treated preventively to avoid an increase in the incidence of tuberculosis in children. However, the recognition of infected cases without disease is often difficult. In particular, minimal active disease may be present in many cases but unrecognised on chest radiography. Computed tomography was therefore perfor...

Dose Reduction Methods in Chest Computed Tomography

Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...

Parapneumonic empyema diagnosed by chest radiograph and computed tomography

Pleural effusion is commonly seen associated with pneumonia. When this progresses to empyema, directed therapy is frequently required. Chest radiographic and computed tomography findings can help distinguish empyema from a transudative pleural effusion.

The value of chest radiograph and computed tomography in pulmonary sarcoidosis.

Imaging makes a significant contribution to the diagnosis, prognosis and follow-up in sarcoidosis. Despite its increasing use, the role of computed tomography (CT) scanning in patients with known or suspected pulmonary sarcoidosis is still undefined. This review aims to compare the utility and limitations of chest radiograph and CT in patients with pulmonary sarcoidosis, with regards to the mos...
