Stereotactic diffusion tensor imaging tractography for Gamma Knife radiosurgery

Gamma knife stereotactic radiosurgery for radiation-induced meningiomas.

BACKGROUND Radiation-induced meningiomas present a unique clinical dilemma given the fact that patients with these tumors have often received a prior full course of radiotherapy. As such, traditional radiotherapy is limited by lifetime tissue tolerances to radiation, leaving surgery and radiosurgery as attractive treatment options. OBJECTIVES To ascertain the safety and efficacy of Gamma Knif...

Gamma Knife Stereotactic Radiosurgery for Nonvestibular Cranial Nerve Schwannomas.

BACKGROUND Nonvestibular cranial schwannomas represent a rare type of benign intracranial tumor. Few studies have evaluated the use of stereotactic radiosurgery (SRS) as a primary management option for these lesions. We performed a retrospective review of our institution's experience focusing on efficacy with regard to tumor control and clinical symptom stabilization as well as treatment safety...

Diffusion Tensor Imaging and Tractography

In selected patients with medically refractory epilepsy, surgical treatment can render the patients seizure free or significantly reduce seizure frequency. Temporal lobe resection (TLR) for temporal lobe epilepsy (TLE) is the most commonly performed epilepsy surgery procedure. A visual field defect (VFD) due to injury to the optic radiation (OR) may occur after TLR. Diffusion tensor imaging (DT...

Gamma Knife Radiosurgery for Acromegaly

Acromegaly is debilitating disease occasionally refractory to surgical and medical treatment. Stereotactic radiosurgery, and in particular Gamma Knife surgery (GKS), has proven to be an effective noninvasive adjunct to traditional treatments, leading to disease remission in a substantial proportion of patients. Such remission holds the promise of eliminating the need for expensive medications, ...
