OBJECTIVE In this study we compared cardiothoracic ratio on chest radiography and left ventricular dimensions from echocardiography in patients with left heart valvular regurgitation. METHODS The studied population consisted of 107 patients (55 male, 52 female) aged 7 to 25 years (11.6+/-4.7 years) with isolated mitral or aortic regurgitation. Chest radiography and echocardiographic examinati...

conclusions despite close concordance between ultrasonography and chest radiography, ceus is not a suitable alternative for standard chest radiography in detecting cvc location; however, considering its high sensitivity and acceptable specificity in our study, its usefulness as a triage method for detecting cvc location on a real-time basis in the operating room cannot be ignored. results chest...

In the study “Is Chest Radiography Necessary After Uncomplicated Insertion of a Triple Lumen Catheter in the Right Internal Jugular Vein, Using the Anterior Approach?” (January 2005),1 Lessnau cites a line misplacement rate of 2%, which was associated with a difficult catheter insertion procedure. All complications were due to misplaced sites, with no episodes of pneumothorax in evidence. In co...

True positive result denotes correct placement of hemodialysis catheter according to bubble-enhanced ultrasound and chest radiography. True negative result 1⁄4 incorrect placement of hemodialysis catheter according to bubble-enhanced ultrasound and chest radiography. False positive result 1⁄4 correct placement of hemodialysis catheter according to bubble-enhanced ultrasound not confirmed by che...

BACKGROUND Public health authorities worldwide discourage the use of chest radiography as a screening modality, as the diagnostic performance of chest radiography does not justify its application for screening and may even be harmful, since people with false positive results may experience anxiety and concern. Despite the accumulated evidence, various reports suggest that primary care physician...

BACKGROUND Chest radiography and electrocardiogram have been criticized due to their low sensitivity for Left Ventricular Hypertrophy diagnosis compared to echocardiogram. This one, however, is not available in primary health care centers to all hypertensive population. OBJECTIVE To evaluate whether the association chest radiography-electrocardiogram provides the accuracy to justify its use i...

BACKGROUND Management of acute respiratory tract infection varies substantially despite this being a condition frequently encountered in pediatric emergency departments. Previous studies have suggested that the use of antibiotics was higher when chest radiography was performed. However none of these analyses had considered the inherent indication bias of observational studies. OBJECTIVE The a...

BACKGROUND With soaring advances in the field of medicine, the place of older radiologic imaging modalities is being reduced to basic screening tools. Yet the modern imaging modalities like computerized tomography (CT), magnetic resonance imaging (MRI), ultrasound and nuclear medicine are hardly available. STUDY OBJECTIVES To study the frequency of various indications of plain chest radiograp...
