|Nominal Values of Static Magnetic Field (T)||1.5-T and 3.0-T|
|40-T/m (4,000-gauss/cm)||Maximum Spatial Field Gradient (T/m and gauss/cm)|
|Type of RF Excitation||Circularly Polarized (CP) (i.e., quadrature-driven)|
|Transmit RF Coil Information||There are no transmit RF coil restrictions. Accordingly, the following may be used: body transmit RF coil and all other RF coil combinations (i.e., body RF coil combined with any receive-only RF coil, transmit/receive head RF coil, transmit/receive knee RF coil, etc.)|
|Operating Mode of MR System||Normal Operating Mode|
|Maximum Whole Body Averaged SAR||2-W/kg (Normal Operating Mode)|
|Limits on Scan Duration||Whole body averaged SAR of 2-W/kg for 60 minutes of continuous RF exposure (i.e., per pulse sequence or back-to-back sequences/series without breaks)|
|MR Image Artifact||The presence of this implant produces an imaging artifact. Therefore, carefully select pulse sequence parameters if the implant is located in the area of interest.|
The Lap-Band® System is MR Conditional.
A patient with the Lap-Band® System may be safely scanned under the following conditions. Failure to follow these conditions may result in injury to the patient.
