Pneumatosis intestinalis in adults with AIDS: clinical significance and imaging findings.
The significance of pneumatosis intestinalis in adults with AIDS is unknown. Adults with AIDS are predisposed to pneumatosis intestinalis. The purpose of this study is to determine the clinical significance and to characterize the imaging appearance of this finding in patients with AIDS. ⋯ Pneumatosis intestinalis is a late-stage phenomenon in adult patients with AIDS that characteristically involves the cecum or right colon. Pneumatosis in patients with AIDS may be an indolent abnormality and does not necessarily constitute a surgical emergency or a sign of impending bowel necrosis.

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.
