Off-hours interpretation of radiologic images of patients admitted to the emergency department: efficacy of teleradiology.
The purpose of our study was to assess the efficacy of a commercially available digital teleradiology system in the off-site interpretation of radiologic studies performed in the emergency department. ⋯ Commercially available teleradiology equipment can be both reliably and effectively used for off-hours interpretation of radiologic studies made in the emergency department.

Comparative StudyInformed consent for percutaneous lung biopsy: comparison of two consent protocols based on patient recall after the procedure.
Informed consent is now required for the majority of radiologic procedures, but few studies have evaluated the efficacy of informed consent protocols. We compared our standard consent protocol of obtaining consent prior to percutaneous lung biopsy with a modified protocol by using patients' recall of procedure risks after the biopsy as an indicator of patients' comprehension. ⋯ The standard consent procedure for lung biopsy appears inadequate when patients' recall of procedure risks later is used as a measure of the patients' comprehension. Based on this study, the informed consent process may be improved substantially by teaching patients to recite the procedure risks to the physician as part of the informed consent protocol.

Quantification of pneumothorax size on chest radiographs using interpleural distances: regression analysis based on volume measurements from helical CT.
The aim of this study was to define the relationship between interpleural distance measurements on an erect posteroanterior chest radiograph and pneumothorax size as measured by helical CT in a series of patients. ⋯ This study identified a formula for accurately calculating percentage pneumothorax size as determined by helical CT from an erect posteroanterior radiograph. Using this formula with the clinical status of the patient should more easily identify patients requiring active intervention.

Traumatic anterior dislocation of the hip: spectrum of plain film and CT findings.
Traumatic anterior dislocation of the hip represents 11% of all hip dislocations and is classified into superior and inferior types [1]. Whereas inferior anterior hip dislocation is easily recognized on an anteroposterior radiograph of the pelvis, the radiographic appearance of superior anterior hip dislocation is less straightforward, often leading to an initial misdiagnosis of posterior hip dislocation. ⋯ In addition, recognition of associated impaction fractures is important, as patients with this finding have a greater tendency to develop traumatic arthritis [2, 3]. This pictorial essay, which is based on our experience with 20 cases of anterior hip dislocation, including five of the rare superior type, illustrates the spectrum of radiographic findings and distinguishing features associated with anterior hip dislocation.

Fractures of the vertebrae with spinal cord injuries in patients with ankylosing spondylitis: imaging findings.
Ankylosing spondylitis is a systemic rheumatologic disorder of adults that results in disease-specific inflammation and eventual ossification at the site of ligamentous insertion into bone. The resulting spinal ankylosis causes biomechanical alterations that predispose the patient to serious spinal injury even in the presence of minor trauma. With the loss of spinal flexibility and increased bone fragility, there is a propensity for vertebral fracture, instability, and increased neurologic complications. Illustrative examples of the imaging modalities are presented, as they contribute to the detection of fractures and spinal cord injuries in patients with ankylosing spondylitis.
