Background: Peripheral nerve pathologies refer to disorders or conditions that affect the peripheral nervous system. The present study comparedhigh-resolution ultrasoundand MRI in detection of peripheral nerve pathologies. Materials & Methods: 70 cases of peripheral nerve pathologies of both genders underwentHigh-resolution ultrasound with 14 MHz linear-transducer and 3 or 1.5T MR. The accuracy, sensitivity, and specificity of these modalities were compared. Results: Out of 70 patients, males were 40 and females were 30. The confidence level for fascicular change on USG and MRI was 100% and 91%, caliber change in 100% and 64%, neuroma/mass lesion in 100% and 92%, nerve discontinuity was detected by 100% in MRI and 87%, increased nerve signal in 74% and 100% respectively. The difference was significant (P< 0.05).USG and MRI showed sensitivity of 84% and 93%, specificity of 100% and 68%, PPV of 100% and 94%, NPV of 45% and 60% and accuracy of 82% and 91% respectively. Conclusion: High-resolution ultrasound is a potent aid that might be employed as the primary imaging modality to assess peripheral nerve diseases.
