Fig 2. A, MR imaging at baseline for a 34-year-old woman who underwent percutaneous plasma radio-frequency–based diskectomy for a disk (C6–7) herniation compressing the spinal cord and causing clinical signs of myelopathy.

B, A 7-week MR imaging follow-up shows regression of both herniation and cord compression; the patient is almost asymptomatic.

C, An MR image at 9-month follow-up shows almost complete regression of the disk herniation; the patient is completely asymptomatic.
