Use LEAD108 Series leads in MRI/fMRI environments with radiotranslucent snap electrodes, such as disposable pre-gelled EL508 or disposable dry EL509.
For MRI use, shorter leads are better. To record any biopotential signal (e.g., ECG, EMG) in MRI, short leads such as LEAD108B (15 cm) and LEAD108C (30 cm) are recommended; do not use 2-meter or 1-meter leads for biopotential signals in MRI.
See BIOPAC MRI Guidelines for details.
MRI Use: Conditional to 9T
Condition: Up to 9T, any scanning sequence, use with EL508 or EL509 MRI/RT electrodes only. (See Specifications for components.)

Lead length when recording in MR environments is critical. Lead lengths must be kept much shorter than the wavelength of the Larmor frequency (42.6 MHz/T). For a 3T machine, this is the speed of light divided by (42.6*3*1E6) or 2.34 meters. As field strengths increase, then lead lengths should continue to shorten.

The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL526 strip electrodes and CBL246 adapter or with EL500 […]
