Prospective safety evaluation of automated iomeprol 400 injections for CT through peripheral venous cannulas.

•Highly viscous contrast medium has complication rates similar to other CM with lower viscosity and concentrations of iodine.•The use of peripheral venous cannulas for the injection of highly viscous contrast medium is a safe procedure.•To minimize extravasation rates, before injections of contrast medium an aspiration test should to be performed.
