OBJECTIVES The aim of this study was to determine the benefit of routine postoperative chest radiography after removal of esophageal foreign bodies in children. METHODS Medical records were reviewed of all patients evaluated with an esophageal foreign body at a single children's hospital over 10 years. Operative records and imaging reports were reviewed for evidence of esophageal injury. RE...

Cardiothoracic ratio (CTR), the ratio of cardiac diameter (CD) to thoracic diameter (TD), is a useful screening method to detect cardiomegaly, but is reliable only on posteroanterior chest radiography (chest PA). We performed this cross-sectional 3-phase study to establish reliable CTR from anteroposterior chest radiography (chest AP). First, CD(Chest PA)/CD(Chest AP) ratios were determined at ...

This study was undertaken to assess the accuracy of clinical examination in predicting significant injury following blunt chest trauma and to determine whether more selective use of frontal chest radiography could be achieved.

Introduction: The introduction of digital radiography has led to a significant problem in terms of dose creep. To address this problem, manufacturers have established a set of exposure indicators (EI) as a feedback mechanism to safeguard against overexposure. The EI is the measure of incident exposure to the detector that is directly proportional to the signal-to-noise...

We have developed computer-aided diagnosis (CAD) schemes for the detection of lung nodules, interstitial lung diseases, interval changes, and asymmetric opacities, and also for the differential diagnosis of lung nodules and interstitial lung diseases on chest radiographs. Observer performance studies indicate clearly that radiologists' diagnostic accuracy was improved significantly when radiolo...

Aims: Chest X ray is the first choice for investigation of cardiovascular and respiratory disease. Radiographer technologists are responsible managing radiation exposure to patients providing adequate image quality according ALARA (As Low as Radiation Achievable) concept. The knowledge skills radiographers in performing chest radiography helps improve diagnosis diseases. aim this study was asse...
