Observational Study
Identifying Institutional Diagnostic Reference Levels for CT with Radiation Dose Index Monitoring Software.
To retrospectively evaluate radiation optimization efforts over 4 years for three computed tomography (CT) protocols and to determine institutional (local) diagnostic reference levels for prospective tracking by using automated radiation dose index monitoring software. ⋯ Automated methods of radiation dose data collection permit a detailed analysis of radiation dose according to protocol and equipment over time. Radiation dose optimization measures were effective, but their full value may be realized only with changes in internal processes and real-time, prospective data monitoring and analysis.

To evaluate the safety and angiographic and clinical outcome of stent-assisted coil placement (SACP) for acutely ruptured wide-necked intracranial aneurysms treated in a single center during an 11-year period. ⋯ Angiographic and clinical outcomes in our series were comparable to those reported by using coil placement alone or balloon-assisted coil placement techniques. SACP for the treatment of acutely ruptured middle cerebral artery bifurcation and anterior communicating artery aneurysms was associated with a significantly higher incidence of complications than was the case for treatment of aneurysms at other locations.
