Table 3 Denervation changes in skeletal muscles as seen in magnetic resonance neurography [1]
Duration | Imaging findings |
|---|---|
Acute (less than 1 month) | T2-weighted images hyperintense areas of edema |
Subacute (1–3 months) | T2-weighted images hyperintense areas of edema and T1-weighted images hyperintense areas of fatty infiltration |
Chronic (more than 3 months) | T1-weighted images hyperintense areas of fatty infiltration and decreased muscle volume of atrophy |
