Study of patients with intravenous contrast extravasation on CT studies, with radiology staff and ward staff cannulations.

Introduction: Intravenous (IV) contrast extravasation is an adverse outcome of computed tomography (CT) studies. This study evaluates for any differences in rates of extravasation between radiology (radiographer) staff and ward medical staff cannulations, and secondarily by cannula size and study type.

Method: A prospective study of 26,854 studies in adults between September 2004 and April 2008 accumulated 119 extravasations.

Prospective evaluation of selected clinical criteria for cranial computed tomography in non-trauma adult patients.

Objective: To evaluate the usefulness of previously published criteria by Rothrock et al. and Harris et al. for urgent, cranial CT in non-trauma presentations.
