Cervical chymopapain nucleolysis: MR imaging assessment of chymopapain efficacy.

Soft cervical disc herniations can be treated by minimally invasive procedures with excellent results. Chemonucleolysis with chymopapain is one alternative to surgery that is shown to be innocuous within a strict technical framework. MR imaging allows an accurate diagnosis of the cause of cervical root compression, thus facilitating the choice of conventional surgery or minimally invasive procedures.
