EEG MRI Compatible
Traditional versus conditional
Traditional are ferromagnetic and contraindicated for MRI
Stipulations conditional
- no sequence > 15 min
- max field 40T
- max SAR of 2W/kg
- extension cables must be removed before the MRI
EEG artifacts in MRI
EEG electrode artifacts extend 3 mm from the skin
How do we differentiate between MRI-compatible and non-MRI-compatible?
a) Braids?
- braids are MRI compatible, non-braids are not MRI compatible
b) Lenght
- non-MRI compatible are long
c) All connected to the same disconnectable cable
