3.0 T MRI Diagnostic Features: Comparison with Lower Magnetic Fields

Direct parasagittal magnetic resonance imaging of the internal auditory canal to determine cochlear or auditory brainstem implant candidacy in children

“…19 We utilize a scanner with a stronger than average magnetic field (3T, measured in tesla [T]) providing an increased signal-tonoise ratio (SNR). 20,21 Not all institutions have this machine available, although the use of the described technique using a 1.5T scanner may also improve image quality. Further, a narrow IAC with minimal cerebrospinal fluid surrounding the cochlear nerve may degrade the diagnostic value of scan.…”
