Cervical nerve roots play a vital role in transmitting motor and sensory information and are frequently affected in neurologic disorders. However, they are extremely delicate structures that lie in close proximity to surrounding tissues, which makes their clear visualization on MRI technically challenging. The objective of this prospective study was to identify the most suitable MRI sequence for visualizing cervical nerve roots in clinically normal dogs. Cervical MRI was performed using three sequences: turbo spin echo with Dixon (TSE+Dixon), dual-echo steady-state with water excitation (DESS+WE), and T2-weighted sampling perfection with application-optimized contrasts using different flip angle evolutions with short tau inversion recovery (T2W-SPACE+STIR). Qualitative and quantitative assessments of cervical nerve root visualization were performed for each sequence. DESS+WE was consistently the most effective sequence for cervical nerve root visualization in both qualitative and quantitative analyses. This study provides fundamental evidence for optimizing MRI sequence selection and acquisition strategies for cervical nerve root assessment, and may contribute to improved diagnostic accuracy across a broad range of clinical applications.
