We reviewed the plain radiographs, bone scans and hip aspiration results of 54 patients with painful hip arthroplasties which had been explored surgically, to compare the results of the investigations with the operative findings. For acetabular loosening, the sensitivity and specificity of bone scanning were 87% and 95%, with an accuracy of 90%: for serial plain radiography sensitivity was 95%,...

INTRODUCTION INTRODUCTION The diagnostic value of colour Doppler sonography for the detection of blood flow in intussusception is questionable. The purpose of this study was to evaluate plain radiography in the assessment of vascular compromise in children with intussusception. MATERIAL AND METHODS The hospital notes of 1,119 paediatric cases of intussusception who presented between Januar...

BACKGROUND Necrotizing enterocolitis (NEC) is one of the most serious disorders of gastrointestinal tract during neonatal period. Early diagnosis and adequate treatment are essential in the presence of clinical suspicion of NEC. Plain abdominal radiography is currently the modality of choice for initial evaluation of gastrointestinal tract in neonates. However, when the diagnosis is uncertain, ...

exploration. The mechanism of injury, the clinical findings, local anaesthetic blocks, contrast arthrography, plain radiography and cine-radiography are the main diagnostic methods available. All or several may provide the necessary assistance. In 1962 Golding described an observation made on plain radiography that we believe is not only valid but can often help in the search for the causative ...

Typical distribution of exposure parameters in plain radiography is unknown in Portugal. This study aims to identify exposure parameters that are being used in plain radiography in the Lisbon area and to compare the collected data with European references [Commission of European Communities (CEC) guidelines]. The results show that in four examinations (skull, chest, lumbar spine and pelvis), th...

Background: While plain radiography is commonly used to assess scaphoid fracture, this imaging modality may not accurately demonstrate early bone healing. This investigation evaluates the utility of 64-slice CT in the detection of early fracture healing compared to plain radiographs and magnetic resonance imaging (MRI). Methods: Outpatients attending follow-up visits for scaphoid fractures at H...

BACKGROUND In 1951, Ardran reported that metastatic bone lesions could be detectable on plain radiography with 30% to 50% of decalcification. Authors performed experimental study for minimum level of decalcification to detect the osteolytic bone metastasis of long bone with recent technique of radiographs. METHODS One pair of fibula and humerus from two cadavers was cut into specimen 1 inch i...

STUDY DESIGN A variety of interbody implants were imaged by computed tomography and plain radiography within cadaveric spines to evaluate their basic imaging characteristics. OBJECTIVES Sources of interpretation error by both computed tomography and plain radiography of interbody implants were investigated. SUMMARY OF BACKGROUND DATA Lucencies have been reported around bone dowel implants i...

BACKGROUND Long bone fractures are common injuries caused by trauma. Some studies have demonstrated that ultrasound has a high sensitivity and specificity in the diagnosis of upper and lower extremity long bone fractures. OBJECTIVE The aim of this study was to determine the accuracy of ultrasound compared with plain radiography in diagnosis of upper and lower extremity long bone fractures in ...
