The retrosternal clear space (RCS) is a lucent area on the lateral chest radiograph located directly behind the sternum. The two types of pathology classically addressed in the RCS are anterior mediastinal masses and emphysema. Diseases of the pulmonary interstitium are a third type of pathology that can be seen in the RCS. Retrosternal reticular opacities, known as Kerley D lines, were initial...

Sixty-six supine portable chest radiographs done on the day of bronchoscopy in 62 critical care unit patients suspected of having pneumonia were examined in a blinded fashion by two radiologists. Quantitative culture results obtained from protected brush catheter (PBC) specimens were compared with chest radiograph scores. For one observer, the sensitivity of the chest radiograph for predicting ...

A 68-year-old woman, who had been diagnosed as idiopathic interstitial pneumonia, complained of progressive dyspnea on exertion for a week. Although her chest radiograph did not worsen, arterial blood gas findings were markedly worsened. Contrast-enhanced chest computed tomography showed filling defects of the right upper and middle lobe branches of the pulmonary artery. She was diagnosed as ha...

Background: Tuberculosis remains a major public health problem in Nigeria and the world at large. Substantial number of cases of tuberculosis occurs in children, especially in this era of HIV pandemic. Chest radiograph is an important examination in evaluation for pulmonary tuberculosis. There is paucity of literature on the chest radiographic features predictive of HIV in pulmonary tuberculosi...

Chest radiography remains the most commonly used method for screening and diagnosing lung diseases, such as lung cancer, pneumothorax, interstitial disease, emphysema and many others. The detectability of a lung disease on a chest radiograph is affected by the signal-to-noise ratio (SNR) in the image. High-contrast bone structures are major noise contributors that significantly reduce the SNR i...

Bronchogenic cyst is a result of abnormal development   of the ventral foregut presents as a discrete mass. Most commonly, it is appeared in the middle mediastinum and rarely is seen in adults. We report a 35-year-old woman who was asymptomatic and incidentally was found with a mass in chest radiograph.  

High levels of exposure to carbon black have been linked with an increased prevalence of chest radiograph abnormalities. However, it is unclear to what extent current levels of exposure in the carbon black manufacturing industry are associated with new cases of and progression in small opacities. Longitudinal analyses were carried out on data from workers in the European carbon black manufactur...

STUDY OBJECTIVES Chest radiographs are required in many institutions by protocol after the insertion of a right internal jugular vein triple-lumen catheter (TLC), even if the anterior approach is used. This study investigates whether correct placement can be predicted during insertion and whether a "routine" postprocedural chest radiograph can be safely omitted. DESIGN The operators included ...

RATIONALE Objective, reproducible quantification of the extent of abnormalities seen on a chest radiograph would improve the user-friendliness of a previously proposed severity scoring system for pulmonary tuberculosis and could be helpful in monitoring response to therapy, including in clinical trials. METHODS In this study we report the development and evaluation of a simple tool using free...
