PurposeTo automate diagnostic chest radiograph imaging quality control (lung inclusion at all four edges, patient rotation, and correct inspiration) using convolutional neural network models.MethodsThe data comprised of 2589 postero-anterior radiographs imaged in a standing position, which were divided into train, validation, test sets. We increased the number images for by cropping appropriate...
Although pneumomediastinum (PM) is a cause of chest pain, which can be diagnosed on a plain chest radiograph, emergency physicians frequently miss the diagnosis. As follows a description of findings of PM on a chest radiograph.
P NEUMOTHORAX is an uncommon but potentially serious occurrence during anesthesia. Initial clinical signs may be subtle, but progression to a tension pneumothorax can result in significant cardiorespiratory instability. Because therapy for pneumothorax may require invasive chest tube placement, definitive diagnosis by chest radiography is necessary. However, intraoperative chest radiograph may ...
results the data showed that vital signs and physical examination findings are useful screening parameters for predicting chest radiograph findings in outpatient settings. therefore, by implementing a prediction rule, we would be able to determine which patients would benefit from a chest x-ray (sensitivity, 94% and specificity, 57%). conclusion this study's findings suggest that requesting che...
BACKGROUND Chest radiographs (CXRs) are used in tuberculosis (TB) prevalence surveys to identify participants for bacteriological examination. Expert readers are rare in most African countries. In our survey, clinical officers scored CXRs of 19 216 participants once. We assessed to what extent missed CXR abnormalities affected our TB prevalence estimate. METHODS Two experts, a radiologist and...
(CHEST 2000; 117:588–590) A n 18-year-old man presented with a history of recurrent chest infections over the past 4 years. The patient had been treated intermittently with several courses of antibiotics. Apart from his chest infections, he had no significant medical or surgical history. On examination, the only significant finding was an area of decreased air entry in the right lower lobe. Lab...
BACKGROUND A number of chest radiographic scores have been developed to assess the severity of respiratory disease in cystic fibrosis but critical statistical evaluation has been limited. In particular, the chest radiograph component of the National Institutes of Health (NIH) clinical score has not previously been validated. Three different chest radiograph scores have been compared and the ass...
The optimal strategy for monitoring cystic fibrosis lung disease in infancy remains unclear. Our objective was to describe longitudinal associations between infant pulmonary function tests, chest radiograph scores and other characteristics. Cystic fibrosis patients aged ≤24 months were enrolled in a 10-centre study evaluating infant pulmonary function tests four times over a year. Chest radiogr...
