ACNS Guidelines for CLTM Exam
Nichrome and platinum are. - ANSWER Nonferrous metal, MRI compatible
LTME digital equipment must record ( minimum) - ANSWER 24 hrs of video and 32-64
channels of EEG
LTME storage (minimum) - ANSWER 30 gigabytes or 24 hrs of vid/EEG
Intracerebral electrode impedance measurements.safe range - ANSWER 10nA
which is 1000 times less than reg 5-10Kohm for scalp
What is the bare minimum number of channels in an LTME or primary EEG evaluation -
ANSWER 8 channels
12 or more are routinely used for accuracy in localization
Electrodes, wires,amplifiers etc - ANSWER Instrumental artifact creators.
Ambulatory EEG artifact.create a reference - ANSWER All common biological and
mechanical arti should be produced by patient/tech at start or end of record.
LTME Quality Assurance - ANSWER Periodic check of live EEG should be preformed
once a day.
16 channels EEG +1 eye and 1 EKG = - ANSWER Minimum number of channels for
presurgical localization.
