OBJECTIVES To evaluate diagnostic imaging costs before and after DTS implementation in patients with suspected thoracic lesions on CXR. METHODS Four hundred sixty-five patients (263 male, 202 female; age, 72.47 ± 11.33 years) with suspected thoracic lesion(s) after CXR underwent DTS. Each patient underwent CT when a pulmonary non-calcified lesion was identified by DTS while CT was not perform...

INTRODUCTION Rapid diagnosis of traumatic intrathoracic injuries leads to improvement in patient management. This study was designed to evaluate the diagnostic value of chest radiography (CXR) in comparison to chest computed tomography (CT) scan in diagnosis of traumatic intrathoracic injuries. METHODS Participants of this prospective diagnostic accuracy study included multiple trauma patient...

OBJECTIVE We describe chest radiograph (CXR) findings in a population with a high prevalence of human immunodeficiency virus (HIV) and tuberculosis (TB) in order to identify radiological features associated with TB; to compare CXR features between HIV-seronegative and HIV-seropositive patients with TB; and to correlate CXR findings with CD4 T-cell count. METHODS Consecutive adult patients adm...

BACKGROUND With the increasing use of thoracic computed tomography (CT) to screen for injuries in pediatric blunt thoracic trauma (BTT), we determined whether chest x-ray (CXR) and other clinical and epidemiologic variables could be used to predict significant thoracic injuries, to inform the selective use of CT in pediatric BTT. We further queried if these were discrepant from factors associat...

BACKGROUND The routine follow-up of patients with disseminated non-seminomatous testicular cancer (DNSTC) treated with the combination of orchidectomy, polychemotherapy, and if needed, resection of the residual mass, consists of regular physical examinations, chest X-rays (CXR) and tumor marker assessments. Most guidelines for this routine follow-up originate from multi-center trials. In order ...

The article by Rubenfeld et al in a recent issue of CHEST (November 1999)1 highlighted a key problem when applying clinical parameters to the definition of a syndrome. In the daily care of an ARDS patient, physicians of various specialties and other health-care personnel are often the first individuals reviewing the chest x-ray (CXR). However, it is the interpretation from the radiology departm...

This study proposes a novel automated method for cardiomegaly detection in chest X-rays (CXRs). The algorithm has two main stages: i) heart and lung region localization on CXRs, and ii) radiographic index extraction from the heart and lung boundaries. We employed a lung detection algorithm and extended it to automatically compute the heart boundaries. The typical models of heart and lung region...

If an aspirate is not obtainable once the NGT is sited, performing the whoosh test is a valuable means to assess the likelihood of the NGT being in the stomach or not. If a positive whoosh test is heard, then a chest radiograph (CXR) can be requested. If the whoosh test is negative, then there is little point in requesting a CXR as the probability of the NGT being in the stomach is very low (in...
