Lowering the thyroid dose in screening examinations of the cervical spine.

The first objective of this study was to test the hypothesis that a lower-dose (14.1 mGy thyroid dose) protocol for helical computed tomography (CT) of the entire cervical spine demonstrates equivalent technical adequacy and diagnostic accuracy as the standard-dose protocol (26.0 mGy thyroid dose) used at our institution.

Quantification of clinical consultations in academic emergency radiology.

Rationale And Objectives: The purpose of this study is to quantify the impact of clinical consultation on the workload of an academic emergency radiology section.

Materials And Methods: Data from a 7-day audit (24 h/d) of the number and length of clinical consultations was expressed as the mean number of consultations per 24 hours and consultation minutes per 24 hours. Consultations performed on images acquired from outside institutions were noted.
