Background: Peripheral neuropathy is one of the most common neurologic problems encountered by primary care physicians and geriatricians in particular. The present study was conducted to compare MRI and USG in the detection of peripheral nerve pathologies. Materials & Methods: 70 cases of peripheral nerve pathologies of both genders underwent HRUS with 14 MHz linear-transducer and 3 or 1.5T MR. The accuracy, sensitivity, and specificity of these modalities compared. Results: Out of 70 patients, males were 40 and females were 30. Nerve discontinuity was detected by 80% in MRI and 100% in USG, increased nerve signal in100%and 76%, fascicular changein 85%and 100%, caliber change in 58% and 100%, neuroma/mass lesion in 92% and 100% in MRI and USG respectively. The difference was significant (P< 0.05).MRI and USG showed a sensitivity of 94% and 84%, specificity of 69% and 100%, PPV of 93% and 100%, NPV of 56% and 48% and accuracy of 92% and 81% respectively. Conclusion: Authors found that as the primary imaging modality for the assessment of peripheral nerve diseases, HRUS is a potent instrument.
