BACKGROUND Supine anteroposterior (AP) chest radiography is an insensitive test for detecting posttraumatic pneumothoraces (PTXs). Computed tomography (CT) often identifies occult pneumothoraces (OPTXs) not diagnosed by chest radiography. All previous literature describes the epidemiology of OPTX in patients with blunt polytrauma. Our goal was to identify the frequency of OPTXs in patients with...

A 35 year old female presents with haemoptysis, epistaxis and acute renal impairment. A chest radiograph is taken and a second radiograph is taken a week later. 1. Which of the following is the least likely diagnosis for these radiographic appearances? a) Pulmonary infarcts b) Systemic sclerosis c) Sarcoidosis d) Vasculitis e) Septic emboli 2. What is the most likely unifying diagnosis given th...

STUDY OBJECTIVE Although chest radiography is quick and inexpensive, previous research suggests that it is often misleading in emergency department (ED) patients with decompensated heart failure, resulting in misdiagnosis and inappropriate treatment. This study determines the rate of negative chest radiography results in patients found to have disease and the potential contribution of negative ...

BACKGROUND Pneumonia is a common illness in all parts of the world and is considered as a major cause of death among all age groups. Nevertheless, only about 5% of patients referring to their primary care physicians with acute respiratory symptoms will develop pneumonia. OBJECTIVES This study was performed to derive practical criteria for performing chest radiographs for the evaluation of com...

OBJECTIVES The aim of this study was to assess the potential value of hand-carried ultrasound (HCU) devices in the diagnosis and follow-up of patients with pleural effusion (PE) after cardiac surgery. METHODS Seventy consecutive patients were evaluated at bedside early after cardiac surgery, in the upright sitting position, using an HCU device on hospital admission and every 3 days until hosp...

The aim of this study was to determine whether computer assisted analysis of lung area on the chest radiograph reliably predicted lung volume in neonates. Anteroposterior chest radiographs taken for clinical purposes were scanned and analysed using a Power Macintosh computer with a Wacom A5 Ultra Pad and NIH image software. The cardiac, mediastinal and thymic densities and areas of perihilar an...

BACKGROUND The appropriate management of the large number of lung nodules detected during the course of routine medical care presents a challenge. We aimed to evaluate the usual clinical practice in solitary pulmonary nodule (SPN) management and associated radiation exposure. METHODS We examined 893 radiology reports of consecutive patients undergoing chest computed tomography (CT) and radiog...

Patients and methods 30 pediatric patients (mean age: 36 months, mean PIM2 11%) with end stage liver failure submitted to liver transplantation from living/dead donor (split). All the patients during the first three postoperative days were submitted to supine chest radiograph and bedside lung ultrasound, during mechanical ventilation or NIV. Three measurements were made in first, second, and th...
