MRI Information

Non-clinical testing has demonstrated that the Nester® Embolization Coil is MR Conditional according to ASTM F2503. A patient with this coil can be scanned safely anytime after placement under the following conditions.

Static magnetic field of 3.0 Tesla or less
Maximum spatial magnetic gradient of 1600 Gauss/cm or less
Maximum MR system reported, whole-body-averaged specific absorption rate (SAR) of 2.0 W/kg (normal operating mode) for 15 minutes of scanning or less (i.e., per scanning sequence)
Static Magnetic Field
The static magnetic field for comparison to the above limits is the static magnetic field that is pertinent to the patient (i.e., outside of scanner covering, accessible to a patient or individual).

MRI-Related Heating
In non-clinical testing, the Nester® Embolization Coil produced a maximum temperature rise of 1.6 °C during 15 minutes of MR imaging (i.e., for one scanning sequence) performed in a MR 3 Tesla System (General Electric Healthcare Excite, HDx, Software 14X.M5) at an MR system reported whole body averaged SAR of 2.9 W/kg (associated with a calorimetry measured whole body averaged value of 2.7 W/kg).
