In 2006, 141 million imaging examinations, including MRI, CT, PET and SPECT, were performed worldwide using a contrast media injector. In many cases, clinicians used power injectors not only for diagnostic studies, but also for interventional procedures.
Cardiologists have commonly used power contrast media injectors to achieve opacification for these diagnostic procedures, which require high flow, high volume, fixed rate injections delivered with relatively high pressures. Typical applications of this sort are ventriculograms, aortograms and run-off studies.
