ACNS guidelines for CLTM exam
Nichrome and platinum are... - CORRECT ANSWER-Nonferrous metal, MRI
compatible
LTME digital equipment must record ( minimum) - CORRECT ANSWER-24 hrs of
video and 32-64 channels of EEG
LTME storage (minimum) - CORRECT ANSWER-30 gigabytes or 24 hrs of
vid/EEG
Intracerebral electrode impedance measurements...safe range - CORRECT
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 - CORRECT ANSWER-8 channels
12 or more are routinely used for accuracy in localization
Electrodes, wires,amplifiers etc - CORRECT ANSWER-Instrumental artifact
creators.
Ambulatory EEG artifact..create a reference - CORRECT ANSWER-All common
biological and mechanical arti should be produced by patient/tech at start or end
of record.
LTME Quality Assurance - CORRECT ANSWER-Periodic check of live EEG
should be preformed once a day.
16 channels EEG +1 eye and 1 EKG = - CORRECT ANSWER-Minimum number
of channels for presurgical localization.
In-patient LTME - CORRECT ANSWER-Qualified personal must observe the
patient, record events and maintain recording integrity
