Contrast media injectors insert viscous fluids into an artery or vein through a small catheter. They are used for CT's. MRI's and angiography procedures, so that the vessels being studied are contrasted.
1. When medical facilities are considering whether a contrast injector is suitable for the types and numbers of procedures performed, they should consider the catheterization injector unit's capabilities, including: programmability and ECG and x-ray generator synchronization and also available configurations.
2. Facilities should make sure that the injector for cardiology or infusion system they are about to purchase is MRI-compatible.
3. These are some requirements for all new and used contrast injectors: disposable syringes, selectable pressure in increments of 10 psi, and an adjustable volume stop in 1 mL increments.
4. These are some requirements for contrast injectors used for angiography: a syringe capacity of 100 mL, a flow range of 0.8-7 mL/sec, a delivery pressure range of 14-82 bar, and an x-ray generator.
5. These are some requirements for catheterization injector units used for CT scanning: a syringe capacity of 125 mL, a flow range of 0.1-7 mL/sec, a delivery pressure range of 0-20 bar, and an x-ray generator.
6. These are the requirements for MRI injectors: a syringe capacity of 60 mL, a flow range of 0.1-7 mL/sec, and a delivery pressure range of 0.7-13.8 bar.
7. Hand-driven syringes may be preferable by some physicians for delicate procedures, since they provide a better feel for resistance than an automatic injector. However, automatic injectors deliver more consistent flow.
8. Some contrast injector systems have contrast media conservation features that could result in significant cost savings.
9. Before making a purchase of either a new or used contrast injector, buyers should negotiate the pricing and supply of disposable syringes and administration sets with the supplier. Suppliers of injectors for cardiology may offer unit doses with prefilled syringes.
