MR Conditional
Important alert
- Patients with a Reveal XT that has been implanted for less than 6 weeks are contraindicated for an MRI procedure.
- Patients with a Reveal XT implanted in sites other than the subcutaneous region of the chest are contraindicated for an MRI procedure.
1Pre-scan checks
- Check that the system has been implanted for more than 6 weeks.
- Check that additional implantable devices are not present.
- Check that abandoned leads are not present.
- An x-ray of the implanted system can verify whether the device is a Reveal XT. An x-ray can also indicate whether the patient has any additional implanted devices. The radiopaque symbol (RAB) is located in the header of the device.
2MRI scan conditions
1.5 T
| Scanner type | hydrogen proton magnetic resonance imaging equipment with a static magnetic field of 1.5 T and 3.0 T RF excitation frequency that is approximately 64 MHz in a 1.5 T static magnetic field and approximately 128 MHz in a 3 T static magnetic field closed bore, cylindrical magnet systems |
|---|---|
| Gradient slew rate | • whole body gradient systems with a gradient slew rate specification of 200 T/m/s or less• Using a whole body gradient system that exceeds the gradient slew rate specification of 200 T/m/s, or any type of special purpose gradient system, is allowed only if the maximum gradient magnetic field (dB/dt) the device is exposed to can be verified to be 100 T/s or less. |
| Whole-body SAR | The whole body SAR as reported by the MRI equipment must be ≤2.0 W/kg. |
| Head SAR | The head SAR as reported by the MRI equipment must be ≤3.2 W/kg. |
| Scan region / position conditions | • Total scan duration over the chest – The uninterrupted duration of active scanning over the chest during MRI (when RF and gradients are on) must not exceed 30 min. If additional chest scans beyond 30 min are necessary, a waiting period of at least 10 min is required.• Total scan duration outside of the chest region – There are no scan duration limitations when imaging areas outside of the chest region, provided the Reveal XT is not in the RF field. |
3.0 T
| Scanner type | hydrogen proton magnetic resonance imaging equipment with a static magnetic field of 1.5 T and 3.0 T RF excitation frequency that is approximately 64 MHz in a 1.5 T static magnetic field and approximately 128 MHz in a 3 T static magnetic field closed bore, cylindrical magnet systems |

3RF COIL / RF excitation
| RF coil | • Do not use a local, interventional, extremity volume, or surface transmit coil over or near the chest, trunk, or shoulder region of the patient.• A local or surface receive-only coil is permissible. |

4Other information
- The Reveal XT causes image distortion for areas in the image that surround the implanted device. Image artifacts 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.
- The images show worst-case artifacts of about 6 cm around the Reveal XT.
- However, patients may experience minor discomfort, due to tissue heating or “tugging”.
- Do not take the Patient Assistant (handheld activator) into the MRI controlled room (magnet room). Doing so can damage the Patient Assistant or the MR scanner.
- Do not bring the Medtronic CareLink Model 2090 programmer into the MRI controlled room (magnet room). It is not MRI safe.
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.
