OBJECTIVES This study aims to define a quantitative measurement method for acetabular version in a standard anteroposterior hip radiograph, assess the intraobserver and interobserver agreements of this method, and compare it with the gold standard computed tomography (CT). PATIENTS AND METHODS Anteroposterior standard hip radiographs and simultaneously taken transverse acetabular CT sections ...

PURPOSE The purpose of this study was to evaluate the validity of commercially available planning software on plain radiographs after THA compared to CT scans as the gold standard. PATIENTS AND METHODS In a prospective clinical study, anteroposterior (AP) radiographs and three-dimensional CT scans (3D-CT) were obtained for 121 patients, who underwent minimally invasive, cementless THA with a ...

BACKGROUND We present a case of a 16-year-old girl with fire-eater's pneumonia (hydrocarbon pneumonitis). The goal of this report was to assess evolution of radiological findings. CASE REPORT The reported case was unique because that was the first completely described case of fire-eater's pneumonia reported in an under-aged person. Moreover, this disease is very rare even in adults and only a...

A cross-sectional study was conducted to determine the prevalence of tuberculosis infection and risk factors for tuberculosis infection among household contacts aged less than 15 years in Bangkok, Thailand, between August 2002 and September 2003. During the study period, 342 index cases with sputum smear positive pulmonary tuberculosis patients were recruited into the study and their 500 househ...

AIMS To reanalyse exposure-response data from a Scottish colliery to gain a more detailed knowledge of the relations between exposure to quartz and risks of silicosis in coal miners, and hence inform the debate on an appropriate occupational standard for respirable quartz. METHODS Detailed data on working times at different quartz concentrations were combined to produce exposure profiles for ...

A scoring system using computerised analysis of digital stored images of knee radiographs has been developed. Measurement is based on the assessment of joint space size. It is sensitive, rapid, and reproducible. Plain radiographs are positioned on an acetate grid; a computer generated grid is superimposed on a digital image of the radiograph viewed on a closed circuit television monitor and the...

Figure 1 Chest radiograph shows cavitation with apical pleural.thickening and marked fibrosis at the left hilum causing deviation of the.trachea to the left. There is also adjacent apical calcification as well as a calcified focus at the left base with localized pleural calcification. The lateral aspect of the left hemidiaphragm is raised with obliteration of the left costophrenic angle. The ap...

Primary pulmonary botryomycosis is a rare cause of haemoptysis and can enter the differential diagnosis of a mass on the plain chest radiograph. The case history is presented of a 63 year old man with botryomycosis which was initially thought to be a bronchial carcinoma. When the diagnosis was made several years later it was found to be secondary to persisting vegetable material in the bronchia...

Three cases of gunshot wounds of the chest are reported, in each of which a bullet was retained within the heart. Although it is rare, the surgeon should consider this possibility if the missile overlies the cardiac silhouette on the plain chest radiograph. Fluoroscopy played an important part in confirming the diagnosis. Cardiopulmonary bypass was used in all cases and provides operating circu...

A one-and-a-half year old boy who presented with a cough, irritability, and refusal of food was found to have an impacted foreign body in his upper esophagus. We present the radiologic findings of the foreign body (a button battery) impacted in the upper esophagus and its complications; namely, mediastinitis and spondylodiscitis after endoscopic removal. Further, plain radiograph and MR imaging...
