Are Taxus stents MRI safe?

TAXUS Express Paclitaxel-Eluting Coronary Stent Through nonclinical testing, the TAXUS Express stent has been shown to be MRI safe at field strengths of 3T or less and a maximum whole-body averaged SAR of 2 W/kg for 15 minutes of MRI. The TAXUS Express stent should not migrate in this MRI environment.

Can you have an MRI with a metal stent?

Stents are metallic cages that hold open a coronary artery after angioplasty. Metallic objects placed in the body can pose problems for MRI scans, which use a strong magnetic field and pulses of radio waves to see inside the body. The magnetic field could dislodge the object, while radio waves could make it heat up.

Can an MRI scan detect blocked arteries?

MRI is quite accurate in detecting blockages in the larger sections of the coronary arteries, but either misses or over diagnoses blockages in the smaller sections. Newer technologies are under development that may improve this result.

Who Cannot have MRI scans?

However, due to the use of the strong magnet, MRI cannot be performed on patients with:

  • Implanted pacemakers.
  • Intracranial aneurysm clips.
  • Cochlear implants.
  • Certain prosthetic devices.
  • Implanted drug infusion pumps.
  • Neurostimulators.
  • Bone-growth stimulators.
  • Certain intrauterine contraceptive devices; or.

Can an MRI detect heart problems?

MRI has proven valuable in diagnosing a broad range of conditions, including cardiovascular anatomical anomalies (e.g., congenital heart defects), functional abnormalities (e.g., valve failure), tumors, and conditions related to coronary artery disease and cardiomyopathy (disease affecting the heart muscle).

Is the Taxus Express stent safe for MRI?

ithrough non-clinical testing, the TAXUS Express Stent has been shown to be MRI safe at field strengths of 3 Tesla or less, and a maximum whole body averaged specific absorption rate (SAR) of 2.0 W/kg for 15 minutes of MRI. The TAXUS&Express Stent should not migrate in this MRI environment.

What kind of tubing is Taxus Liberte stent made of?

TAXUS Liberte stents are manufactured from 316L stainless steel tubing. The stent design consists of a dimensionally uniform pattern of radially expandable elements that share junctions with adjacent radially expandable elements.

What is the active ingredient in Taxus Express 2?

The stent component of the TAXUS Express 2 Stent System (referred to as the TAXUS Express Stent) is a stent with a drug / polymer coating formulation consisting of paclitaxel (the active ingredient) and TransluteTM polymer carrier (the inactive ingredient). 1.2.1 Paclitaxel

Can a stent be disturbed in an MRI?

As earlier reported by heart wire , vestigial concerns over stents in MRI machines have stemmed from early speculation that the stent could be disturbed by the ferromagnetic force of the MR, potentially exposing the stent surface to platelets, triggering stent thrombosis.
