MR Conditional

Susceptibility artifacts, such as those related to MR Conditional metal implants, will result in incorrect 3D Geometry Correction. Please carefully verify images.

If the calibration scan covers a region containing MR Conditional metal implants, the calibration images are expected to have distortion and signal void artifacts. Therefore, PURE and ASSET images that have MR Conditional metal present should not be used for post processing.

READY View fusion does not function reliably if MR Conditional metal implants are present and a reference image other than the original image is used. READY View Fusion should not be applied on series if the image area includes MR Conditional metal implants. Strong B0 and B1 distortion caused by MR Conditional metal implants will cause image distortion and signal void in images. Reference images may have different level of distortion (e.g., MAVRIC SL versus non-MAVRIC SL) with functional series, and mis-registration will occur.

Due to the strong magnetic field disturbance in a region containing metal, do not use the RF Drive Mode parameter: Optimized.

Do not use the PURE image filter when acquiring scans in the vicinity of metallic implants or devices. Signal distortion effects are not predictable and will result in incorrect images.

The tests commonly employed to determine MR Conditional implant heating safety (standard, ASTM F2182, ASTM.org), require quadrature excitation. Heating results for non-quadrature excitation (such as parallel transmit, MultiDrive, or elliptical drive) are unknown. For patients with MR Conditional implants or devices, applying Preset or Optimized RF Drive Modes may violate the MR Conditional specifications.
