BACKGROUND Heart size is an important and effective parameter in chest X-ray (CXR) interpretation. Studies indicate that, especially in middle-aged men, increased cardiothoracic ratio (CTR) is associated with ischemic heart disease (IHD) and increased rate of morbidity and mortality. The CXR is the most common imaging examination of the heart. OBJECTIVES A good quality posterior-anterior (PA)...

R daily chest radiography (CXR) is common in intubated and mechanically ventilated patients. A key justification is the belief that routine chest radiographs allow prompt detection of problems that could be missed by clinical evaluation, such as early pneumothoraxes, or malpositioned endotracheal tubes. Results of a previous study1 suggested that these abnormalities are relatively minor and unl...

OBJECTIVE The aim of this validation study was to assess the completeness of the registrations of chest X-rays (CXR) in two different versions of the Danish National Patient Registry (DNPR). MATERIAL AND METHODS We included electronic record data on CXR performed on patients aged 40 to 99 years from nine radiology departments covering 20 Danish hospitals. From each department, we included dat...

Background: Post-treatment I-131 whole body scan (WBS) is known to be a very sensitive test in detecting metastasis in differentiated thyroid cancer (DTC). Therefore, in the presence of this sensitive method, the role of chest radiography (CXR) in the diagnosis of pulmonary metastasis has been questioned. Objective: The present study aimed to find the prevalence of pulmonary metastasis found on...

BACKGROUND Chest radiography (CXR) is inferior to Thin-section computed tomography in the detection of asbestos related interstitial and pleural abnormalities. It remains unclear, however, whether these limitations are large enough to impair CXR´s ability in detecting the expected reduction in the frequency of these asbestos-related abnormalities (ARA) as exposure decreases. METHODS Clinical ...

BACKGROUND Chest radiography (CXR) is frequently performed in Western societies. There is insufficient knowledge of its diagnostic value in terms of changes in patient management decisions in primary care. AIM To assess the influence of CXR on patient management in general practice. DESIGN OF STUDY Prospective cohort study. SETTING Seventy-eight GPs and three general hospitals in the Neth...

Introduction Chest ultrasound (CU) has been suggested as an alternative to CXR to detect the majority of pulmonary abnormalities and misplacements of central venous lines. A good diagnostic accuracy has been reported for CU in intensive care units and postoperative setting, whereas chest auscultation (CA) shows a poorer diagnostic accuracy ([1], [2]) than CXR. The use of CA, CU and CXR as guide...

INTRODUCTION Community-acquired pneumonia (CAP) caused by Streptococcus pneumoniae is a substantial cause of morbidity and mortality among older adults. This study estimated incidences of CAP, chest x-ray-confirmed CAP (CXR+CAP), S pneumonia- positive CAP, S pneumonia-positive CXR+CAP, and S. pneumoniae serotype distribution among 46,000 at-risk adults aged ≥ 50 years residing in Chrzanów Count...

BACKGROUND Many emergency physicians order chest x-rays (CXRs) for pediatric patients who present with a chief complaint of chest pain despite a paucity of research to support this testing, which exposes patients to radiation, cost, and delays. OBJECTIVES This study aimed to begin development of a decision making tool that will allow emergency physicians to selectively obtain CXR films in ped...

BACKGROUND Thoracic ultrasound (EFAST) has shown promise in inferring the presence of post-traumatic pneumothoraces (PTXs) and may have a particular value in identifying occult pneumothoraces (OPTXs) missed by the AP supine chest radiograph (CXR). However, the diagnostic utility of hand-held US has not been previously evaluated in this role. METHODS Thoracic US examinations were performed dur...
