MR Conditional
Important alert
- Required: Ensure that the patient has no other devices, leads, or implanted items that are known to pose a hazard in an MR environment.
1Pre-scan checks
- That the patient has a LINQ II device.
- That the patient has no other devices, leads, or implanted items that are known to pose a hazard in an MR environment.
- Ensure that the pre-scan cardiology responsibilities have been performed.
- You can use an x-ray image of the LINQ II device, such as shown in Figure 1, to identify that the patient has a LINQ II device. LINQ II devices are typically implanted in the left chest area. [p. 6]
- Required programming settings: None prior to the MRI exam.
- If you have questions about whether the patient should receive an MRI scan, contact the patient’s cardiologist.
2MRI scan conditions
≤3 T
| Field strength | Static magnetic field (B0) [T]: ≤3 T |
|---|---|
| Scanner type | Type of nuclei: Hydrogen proton Static magnetic field (B0) orientation: Horizontal, cylindrical bore / Perpendicular to patient, AP (anterior – posterior) / Perpendicular to patient, LR (left – right) |
| Spatial gradient | Maximum spatial field gradient (SFG) [T/m and gauss/cm]: ≤25 T/m (2500 gauss/cm) |
| Gradient slew rate | Maximum gradient slew rate per axis (T/m/s): ≤200 T/m/s |
| Operating mode | RF operating mode or constraints: First level controlled operating mode or normal operating mode |
| Whole-body SAR | Whole-body specific absorption rate (SAR) [W/kg]: ≤4 W/kg |
| Head SAR | Head SAR [W/kg]: ≤3.2 W/kg |
| B1+rms | Maximum B1+RMS [µT]: No limit (see entry for Whole-body specific absorption rate) |
| Scan region / position conditions | • Anatomy at isocenter: No patient-landmark restrictions.• Patient position in scanner: Any• Scan duration and wait time: No limits on scan duration or post-scan wait time for the labeled RF conditions. No limits on post-insertion wait time prior to an MRI scan for the labeled RF conditions. |
3RF COIL / RF excitation
| RF coil | • RF transmit coil type: Integrated whole-body transmit RF coil / Detachable head transmit/receive RF coil / Detachable extremity transmit/receive RF coil• RF receive coil: Any receive-only RF coil may be used. |

4Other information
- It is acceptable to scan patients who have multiple MR Conditional devices, as long as the MR labeling conditions for all implants are satisfied.
- It is acceptable to scan patients who have LINQ II devices that have been abandoned if the MRI conditions for use are satisfied.
- Do not bring the tablet that the Reveal LINQ Mobile Manager clinician app is installed on, the Patient Assistant, or the patient monitor into Zone 4 (MRI magnet room), as defined by the American College of Radiology. They are MR Unsafe.
- Image artifact and distortion resulting from the presence of the device within the field of view must be considered when selecting the field of view and imaging parameters. These factors must also be considered when interpreting the MRI images.
- 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.
