Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Hand-injects iodinated contrast through catheters, sheaths, drains, or biliary/urinary tubes for real-time fluoroscopic imaging. Typical procedural contexts include angiography, venography, drain checks, nephrostograms, and cholangiograms.
What most clearly distinguishes it from similar devices?
Key distinctions
Hand injection gives the operator immediate tactile and fluoroscopic control over a small contrast bolus, unlike a power injector that delivers a programmed volume and flow rate.
