Important alert

  • Do not use local transmit coils on the chest, trunk, or shoulder region.

1Pre-scan checks

    • The patient records must be complete and accurate because radiology uses the records to verify that the patient has a Reveal LINQ device and that the patient has no other devices, leads, or implanted items that are known to pose a hazard in an MR environment.
    • The pre-scan cardiology responsibilities have been performed.
    • An X-ray image of the Reveal LINQ device, such as shown in Figure 1, can be used to identify that a patient has a Reveal LINQ device (typically implanted in the left chest area). [p. 5]
    • If the radiology staff has questions about whether the patient should receive an MRI scan, the staff should contact the patient’s cardiologist.

    2MRI scan conditions

    1.5 T

    Scanner typeHydrogen proton MRI equipment must be used.
    Spatial gradientMaximum spatial gradient of the static magnetic field specification must be ≤25 T/m (2500 gauss/cm).
    Gradient slew rateWhole body gradient systems with gradient slew rate specification must be ≤200 T/m/s per axis.
    Whole-body SARThe Whole Body Specific Absorption Rate (WB-SAR) as reported by the MRI equipment must be ≤4.0 W/kg
    Head SARThe head SAR as reported by the MRI equipment must be ≤3.2 W/kg.

    3.0 T

    Scanner typeHydrogen proton MRI equipment must be used.
    Spatial gradientMaximum spatial gradient of the static magnetic field specification must be ≤25 T/m (2500 gauss/cm).
    Gradient slew rateWhole body gradient systems with gradient slew rate specification must be ≤200 T/m/s per axis.
    Whole-body SARThe Whole Body Specific Absorption Rate (WB-SAR) as reported by the MRI equipment must be ≤4.0 W/kg
    Head SARThe head SAR as reported by the MRI equipment must be ≤3.2 W/kg.

    3RF COIL / RF excitation

    RF coil• Do not use local transmit coils on the chest, trunk, or shoulder region.• There are no restrictions on the placement of receive-only coils, and there are no restrictions on the use of local transmit or receive coils for imaging of the head or extremities.

    4Other information

    • The Reveal LINQ device causes image distortion for areas in the image that surround the implanted device. When selecting the field of view and imaging parameters and when interpreting the MRI images, consider image artifacts and distortion that result from the presence of the device within the field of view.
    • Due to the static magnetic field and gradient magnetic fields produced by MRI equipment, the magnetic material of an implanted device may exert force, vibration, and torque effects that the patient may or may not feel. Such effects will not harm the patient or damage the device.

    These conditions are based on the source document shown below (revision and date). Before scanning, verify the patient's complete system (device, leads, and any other implants) against the latest manufacturer labeling.
