What am I looking at?
Visual recognition
Vial or syringe containing calibrated embolic microspheres that have been loaded with chemotherapy, usually prepared as a suspension immediately before transarterial delivery.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Calibrated beads that lodge in tumor-feeding arteries while eluting loaded chemotherapy (chemoembolization). Typical procedural contexts include transarterial chemoembolization (TACE) of liver tumors.
What most clearly distinguishes it from similar devices?
Key distinctions
These are calibrated microspheres that also serve as a chemotherapy-delivery platform, combining particulate embolization with local drug elution rather than functioning as inert particles alone.
