Is cardiac stent contraindication for MRI?

Is cardiac stent contraindication for MRI?

Coronary artery stents, prosthetic cardiac valves, metal sternal sutures, mediastinal vascular clips, and epicardial pacing wires are not contraindications for MRI, in contrast to pacemakers and implantable cardioverter-defibrillators. Appropriate patient selection and precautions ensure MRI safety.

Are vascular stents MRI safe?

Most coronary and peripheral vascular stents that have been tested have been labeled as “MR safe”; the remainder have been labeled as “MR conditional.”1 Tested coronary artery stents (including tested drug-eluting coronary stents) that are nonferromagnetic (all currently used coronary stents) can be safely scanned at 3 …

Are femoral stents MRI safe?

Conclusion: MRI can be used to visualize both the lumen and wall of SFAs containing selected nitinol stents ex vivo and in vivo. These results suggest that MRI can be used to monitor restenosis in stents placed in the femoral arterial bed.

Is MRI safe for heart patients?

An MRI can be performed on any part of your body. However, a heart or cardiac MRI looks specifically at your heart and nearby blood vessels. Unlike a CT scan, an MRI does not use ionizing radiation. It’s considered a safer alternative for pregnant women.

Is the Promus Premier stent safe for MRI?

Magnetic Resonance Imaging (MRI) Safety Information: Non-clinical testing has demonstrated that the Promus PREMIER Stent is MR Conditional for single and overlapped conditions up to 74 mm. A patient with this device can be safely scanned in a Magnetic Resonance system meeting the following conditions: Static magnetic field of 3.0 and 1.5 Tesla only

When to use Promus Premier everolimus platinum chromium stent?

Use of the Promus PREMIER Everolimus-Eluting Platinum Chromium Coronary Stent System is contraindicated in patients with known hypersensitivity to: Patients judged to have a lesion that prevents complete inflation of an angioplasty balloon or proper placement of the stent or delivery device.

Can a Promus element migrate in an MRI?

Normal operational mode (maximum whole body averaged specific absorption rate (SAR) of lower than 2.0 W/kg) for a total active MR scan time (with RF exposure) of 15 minutes or less The PROMUS Element stent should not migrate in this MRI environment.

What is the maximum magnetic field of PROMUS Premier?
