Can the Dual Lumen Bolt be used in an MR environment?
- Non-clinical testing has demonstrated the Hemedex QFlow 500™ Titanium Bolt Kit is MR Conditional. A patient with this device can be safely scanned in an MR system meeting the following conditions:
- Static magnetic field of 3.0 T or less;
- Maximum spatial field gradient of 8,610 G/cm (86.1 T/m);
- Maximum MR system-reported, whole-body averaged specific absorption rate (SAR) of 2 W/kg (Normal Mode).
- Under the scan conditions defined above, the Hemedex QFlow 500™ Titanium Bolt Kit is expected to produce a maximum temperature rise of less
than 0.3 ºC after 15 minutes of continuous scanning at 1.5 T and less than 0.6 ºC after 15 minutes of continuous scanning at 3 T. - In non-clinical testing, the image artifact caused by the device extends approximately 25 mm from the Hemedex QFlow 500™ Titanium Bolt when
imaged with a gradient echo pulse sequence and a 3 T MRI system. - Prior to transporting the patient to the MRI suite, remove all MR unsafe/conditional sensors that are not labelled for use in an MR environment.
- NOTE: Never leave Stylets or MR unsafe/conditional sensors that are not labeled for an MR environment in the bolt during MRI.
- Hemedex recommends that the lumens be closed/capped following the removal of any sensors.
