MRI syringes: What you need to know to find the right one
Many individuals benefit from magnetic resonance imaging technology today. Healthcare providers request MRIs when they need detailed images of a person’s body parts. When completing these scans, the provider often uses a special syringe to inject a contrast agent into the patient. The right syringe must be used to ensure the accuracy of the images while protecting the patient from harm. How can the provider know which syringe to use?
Machine compatibility
When choosing MRI syringes, the first thing the provider must consider is the compatibility of each syringe with the MRI machine being used. A standard syringe containing any metal components should not be used with MRI machines because of the strong magnetic fields. The MRI syringe should be made of glass, plastic, or certain ceramics. These materials won’t interfere with the operation of the machine or harm the patient.
Safety considerations
Before using any syringe with an MRI machine, ensure it is labeled MRI safe or MR conditional. This lets the technician know the syringe has undergone testing and is safe for use during an MRI. The syringe should also comply with international safety standards regarding syringe and MRI compatibility. ASTM F2503 is one safety standard that applies to these syringes.
Plunger movement
The syringe’s plumber must be both smooth and precise. If it is not, the medication or contrast agent won’t be injected easily or accurately. In addition, a high-quality plunger made with polymer or silicone encounters less friction when used. This leads to more control over the injection process.
Luer Lock connections
No provider wants an accidental disconnection when injecting a contrast agent or medication for an MRI. A Luer lock connection eliminates the risk of this happening. This connection features a twist-and-lock mechanism which creates a tight seal that won’t leak.
Contrast agent compatibility
Before using a contrast agent with a syringe, check to make sure the two are compatible. Certain materials could react with the contrast medium being used. This reaction could alter the properties of the contrast agent and possibly change the imaging results.
Single-use syringes
MRI syringes should never be used more than once. These sterile syringes are designed to prevent an infection. Because they are only used once, there is no risk of cross-contamination. If a syringe has been used and resterilized, throw it away rather than use it.
Syringe volume
When selecting a syringe for an MRI, choose one that fulfills the exact requirements of the procedure. These devices come in a range of sizes, making it easy to find the right one for the patient. This syringe should come with graduation markings that can easily be read to ensure accurate measurements and the correct dosing.
Quality concerns
Only use those syringes that have received FDA approval and are made by a reputable manufacturer. This is one area where corners should not be cut. This approval signals the syringe meets established requirements and has been thoroughly tested to ensure it is safe to use and meets performance requirements.
Ease of use
One other thing to consider when choosing an MRI syringe is how easy it is to use the syringe. Look for devices with comfortable grips. In addition, review the plunger motion to ensure it slides smoothly before making a purchase.
An imaging procedure is only successful when the right MRI syringe is used. In addition, this syringe is needed to ensure the safety of the patient. Consider all factors when choosing a syringe for this procedure to obtain images that are accurate and efficient while keeping the patient safe from harm.
