To review the literature and present our experience in Contrast Extravasations (CE) for CT in a large academic medical center.

The investigation is IRB, HIPPA, and informed consent compliant. There were 352 125 injections between June 2008 and June 2013. The radiology data and medical records of patients in whom CE occurred were reviewed. 

In CT, the EXR was 0.13% (451/352 125, 254 female and 197 male). There was a statistically significant difference between females and males in overall EXR (p=0.0062), and the number of extravasations between CT and MRI (p= <0.0001). The majority of extravasations occurred in outpatients (64.5% [291/451]), but the overall incidence of CE was highest in inpatients (0.29% [160/54 664]).

In this large retrospective review we found that the elderly (>60 yr), females, and inpatients are at the highest risk of extravasation after contrast-enhanced studies in CT. 

Knowledge of the risk factors associated with contrast extravasation for CT can be used to identify vulnerable groups, and help create or strengthen CE risk modification programs.
