Trigeminal neuralgia radiosurgery: the University of Pittsburgh experience.
The results of Gamma Knife stereotactic radiosurgery in the management of 51 patients who had typical trigeminal neuralgia were evaluated at the University of Pittsburgh. In all cases, a 4-mm isocenter was targeted at the proximal nerve at the root entry zone. The target dose varied from 60 to 90 Gy. ⋯ A maximum radiosurgery dose > or = 70 Gy was associated with a significantly greater chance for complete pain relief. Using magnetic resonance imaging stereotactic targeting, the proximal trigeminal nerve is an appropriate anatomic target for radiosurgery. Gamma Knife radiosurgery is a useful additional surgical approach in the management of medically or surgically refractory trigeminal neuralgia.

Use of magnetic resonance imaging in stereotactic surgery. A survey of members of the American Society of Stereotactic and Functional Neurosurgery.
Members of the American Society of Stereotactic Functional Neurosurgery were surveyed to determine the current use of magnetic resonance imaging (MRI) for stereotactic coordinate determination. Of 137 respondents, 48% used MRI as the sole technique for some biopsy procedures. ⋯ Significant factors related to the use of MRI amongst individual surgeons included the performance of > or = 2 stereotactic surgeries per week, the performance of radiosurgery, and being in an academic practice (p < 0.0004). The increasing use of MRI in stereotactic surgery must be coupled with quality assurance testing from frame manufacturers, imaging manufacturers, and surgeons.
