Conditional 8
Conditional 8 – Note: This information pertains to an implant/device that has MRI labeling at 1.5-Tesla and 3-Tesla, only.
The implant/device was determined to be MR Conditional according to the terminology specified in the American Society for Testing and Materials (ASTM) International, Designation: F2503. Standard Practice for Marking Medical Devices and Other Items for Safety in the Magnetic Resonance Environment. Non-clinical testing demonstrated that the implant/device is MR Conditional. A patient with this implant/device can be scanned safely immediately after placement under the following conditions: • Static magnetic field of 1.5-Tesla and 3-Tesla, only • Maximum spatial gradient magnetic field of 720-gauss/cm (a higher spatial gradient magnetic field value may apply if properly calculated) • Maximum MR system reported whole-body-averaged specific absorption rate (SAR) of 2-W/kg (i.e., the Normal Operating Mode) for 15 minutes of scanning (per pulse sequence) MRI-Related Heating In non-clinical testing, the implant/device produced the following temperature rises during MRI performed for 15-minutes (i.e. per pulse sequence) in 1.5-Tesla and 3-Tesla MR systems, using an MR system reported, whole body averaged SAR of 2-W/kg or less, as follows: Highest temperature changes Less than or equal to 6.0 degrees C at 1.5-T/64-MHz Less than or equal to 6.0 degrees C at 3-T/128-MHz Artifact MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the implant/device. In some cases, the artifact size relative to the size of the implant or device may be indicated. Attention: Contact the manufacturer of this implant/device for further information. ** FOR ADDITIONAL INFORMATION, PLEASE REVIEW THE "TERMINOLOGY" MENU CHOICE ON THE MAIN MENU OF MRIsafety.com HOMEPAGE. |
