Nonclinical testing has demonstrated that the Resonance® Metallic Ureteral Stent is MR Conditional. It can be scanned safely under the following conditions:

At 1.5 Tesla Static Magnetic Field

• Spatial gradient field of 450 Gauss/cm or less
• Maximum whole-body-averaged specific absorption rate (SAR) of 1.5 W/kg for 20 min. of scanning
• In nonclinical testing the stent produced a temperature rise during scanning of less than 0.80°C at an SAR of 1.5 W/kg for 20 min.

At 3 Tesla Static Magnetic Field

• Spatial gradient field of 720 Gauss/cm or less
• Maximum whole-body-averaged specific absorption rate (SAR) of 3 W/kg for 15 min. of scanning
• In nonclinical testing the stent produced a temperature rise during scanning of less than 1.3°C at an SAR of 3 W/kg for 15 min.

Note: MR image quality may be compromised if the area of interest is in the same area or relatively close to the position of the stent.

It may be necessary to optimize MR imaging parameters for the presence of this metallic implant.
