Are stainless steel stents MRI safe?

Are stainless steel stents MRI safe?

In general, SS stents are unlikely to undergo displacement. However, extreme caution should be exercised during MRI. In addition, many studies have found that heating of SS stents in a magnetic field does not endanger patients.

Are current cardiovascular stents MRI safe?

All current stents are MRI safe and MRI can be done anytime.

Are sternal wires safe for MRI?

Cardiac MRI is safe with joint replacements, coronary stents, ASD/PFO closure devices, sternal wires and most prosthetic heart valves. Patients with a history of metallic implants / shrapnel / prior neurosurgical clip placement are all individually evaluated prior to MRI.

Is Watchman device safe for MRI?

MRI safety testing has shown that the WATCHMAN Left Atrial Appendage Closure Device is “MRI Conditional” and that a patient with a WATCHMAN Implant may safely undergo an MRI scan under certain conditions listed on the WATCHMAN Device Implant Card.

Can I have an MRI if I have an IVC filter?

IVC filters can pose a threat to MRI safety, as some of the implantable filters are made of metal that can be attracted to the magnets used in MRIs. If precautions are not taken, people who have had an IVC filter implanted can suffer serious injuries if they have an MRI.

Is the express LD stent safe to scan?

Non‐clinical testing has demonstrated the Express LD Stent in single and overlapped conditions is MR Conditional. It can be scanned safely, immediately after placement of this implant, under the following conditions:   Static magnetic field of 1.5 Tesla or 3.0 Tesla. 

What is the Melodie Express LD stent study?

MELODIE is a prospective, multi-center, single arm study to obtain additional data on the safety and efficacy of the Express™ Vascular LD stent implantation in the treatment of stenosed or occlusive atherosclerotic disease (de novo or restenotic) in iliac arteries (common or external).

What’s the maximum temperature rise for a stent?

In this testing, the stent experienced a maximum temperature rise of 0.96 ºC at a maximum whole body averaged SAR of 2.0 W/kg for 15 minutes of MR imaging. The temperature rise was observed to be similar for a stent with a fractured strut.

What is the objective endpoint of the express LD stent?

The objective was to demonstrate non-inferiority of the Express™ LD Stent for the treatment of atherosclerotic iliac artery lesions as compared to an objective performance criterion* (OPC), with a primary endpoint of mean percent luminal diameter loss at 6 months. *Note: the OPC=15%, δ=5%. 1Post MLD = Post-procedure minimum lumen diameter.
