Kestle, John R. W. | Comparison between magnetic resonance imaging and computed tomography for stereotactic coordinate determination | The spatial accuracy of magnetic resonance imaging (MRI) has not been established for stereotactic surgery. Magnetic susceptibility artifacts may lead to anatomical distortion and inaccurate stereotactic MRI coordinates, especially when targets are in regions of the brain out of the center of the ma... | Computed tomography; Stereotactic coordinates; Stereotactic surgery | 1992 |

Kestle, John R. W.; Walker, Marion L. | Noncommunicating spinal extradural arachnoid cyst causing spinal cord compression in a child | Extradural arachnoid cysts in the spine are relatively uncommon causes of spinal cord compression in the pediatric population that are thought to arise from congenital defects in the dura mater. Most reports describe such cysts communicating with the intrathecal subarachnoid space through a small de... | | 2006 |
