Method of preparation of ultrasound contrast
Saline is drawn into a syringe (top left) – both provided in the pack – and then injected into a vial (top right) containing the dry powder constituting the shell and also containing the inner gas.
The vial is then agitated / shaken for 30-60s (bottom left) to mix the contents effectively and the contrast suspension is then ready to be drawn up into a syringe (bottom right) ready for intravenous injection.
