We conducted this study to define the value of fiberoptic bronchoscopy (FOB) in the evaluation of chest radiographic abnormalities and to provide guidelines for fiberoptic bronchoscopy on the basis of chest radiographic appearances. Fiberoptic bronchoscopy without fluoroscopy was carried out in 530 patients, 455 male and 75 female, aged 19 to 85 years, during a 1-year period at Chest Department...

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...

Portable chest radiographs (CXRs) are commonly used in the intensive care unit (ICU) to detect subtle pathological changes. However, exposure settings or patient and apparatus positioning deteriorate image quality in the ICU. Chest x-rays of patients in the ICU are often hazy and show low contrast and increased noise. To aid clinicians in detecting subtle pathological changes, we proposed a con...

OBJECTIVE We observed patients in whom the fluid collection in the right lateral portion of the superior aortic recess on computed tomography (CT) scans mimicked a right anterior mediastinal mass on chest PA radiographs. The purpose of this study was to assess chest PA and CT features of these patients. MATERIALS AND METHODS All chest PA radiographs and CT scans in 9 patients were reviewed by...

To find how computed tomography (CT) may be effectively used in individuals with suspected asbestos related lung disease 30 men with a history of exposure to asbestos were studied. All subjects underwent high kilovoltage posteroanterior and left lateral chest radiographs and chest CT. Eighteen were randomly selected asbestos workers referred for routine surveillance. The remaining 12 were patie...

OBJECTIVE The purpose of this study was to determine, with CT as the reference standard, the ability of radiologists to detect pleural effusions on bedside chest radiographs. MATERIALS AND METHODS Images of 200 hemithoraces in 100 ICU patients undergoing chest radiography and CT within 24 hours were reviewed. Four readers with varying levels of experience reviewed the chest radiographs and pr...

The Chrispin-Norman chest radiograph scoring (CNS) system is widely used to assess respiratory disease progression in cystic fibrosis (CF). Frontal and lateral chest radiographs were performed. The present authors developed a modified CNS, which obviates the need for the lateral film. This study compares the original and the current authors' modified scoring system. A total of 50 chest radiogra...

The differential diagnosis of dyspnea in patients with prior malignancy and nondiagnostic chest radiographs is broad. We report a case of breast carcinoma diffusely metastatic to the bronchial submucosa presenting as obstructive airway disease. Chest radiographs failed to suggest metastatic disease as the cause of dyspnea. CT, however, revealed the unusual finding of diffusely thickened and nar...
