What Is a Contrast Media Injector?
A contrast media injector is a medical device widely used in diagnostic imaging procedures such as CT, MRI, and angiography (DSA). Its primary role is to deliver contrast agents and saline into the patient’s body with precise control of flow rate, pressure, and volume. By enhancing the visibility of blood vessels, organs, and potential lesions, contrast injectors play a vital role in improving image quality and diagnostic accuracy.
These devices are equipped with several advanced features, including:
Accurate flow and pressure control for both small and large injections.
Single- or dual-syringe design, often separating contrast media and saline.
Real-time pressure monitoring with safety alarms.
Air purge and safety lock functions to prevent air embolism.
Modern systems may also integrate Bluetooth communication, touch-screen controls, and data storage.
Depending on clinical needs, there are three main types:
CT injector → High speed, large volume injection.
MRI Injector → Non-magnetic, stable, and lower flow rates.
DSA Injector or Angiography injector → Precise control for vascular imaging and interventional procedures.
