MRI-Based Estimation of Scalar Cochlear-Implant Electrode Position

Figure 3

(a) MRI scalar pattern of a changing scala position (ST > SV) in Patient 1’s basal turn. The arrow indicates the array’s diminishing signal in the scala tympani. The star indicates the scala vestibuli in the basal turn. (b) MRI scalar pattern of a changing scala position (ST > SV) in Patient 1’s second turn. The white arrow indicates the electrode’s diminishing signal in the second turn. The black arrow indicates the scala tympani in the second turn. (c) FPT pattern of a changing scala position in Patient 1. The stars indicate the scala tympani in the basal and second turns. The white arrow indicates the scala vestibuli’s position in the second turn. The black arrow indicates the scala tympani’s position in the basal turn.
