With the currently available imaging modalities, scanning has become quick and robust providing a high degree of spatial resolution resulting in optimal contrast between normal and abnormal tissues. Magnetic resonance imaging (MRI) forms the backbone of Leksell radiosurgery. It produces images with excellent soft tissue details highlighting the target and surrounding \u201cat-risk\u201d structures conspicuously. However, one must be aware of the MRI distortions that may arise during treatment. Computed tomography (CT) has quick acquisition times giving excellent bony information but inferior soft tissue details. To avail benefits of both these modalities and overcome their individual fallacies and shortcomings, they are often co-registered\/fused for stereotactic guidance. Vascular lesions like an arteriovenous malformation (AVM) are best planned with cerebral digital subtraction angiography (DSA) in conjunction with MRI. In specific cases, specialized imaging methods like magnetic resonance (MR) spectroscopy, positron emission tomography (PET), magneto-encephalography (MEG), etc., may be added to the treatment planning for stereotactic radiosurgery (SRS).<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0028-3886.373642","type":"journal-article","created":{"date-parts":[[2023,8,24]],"date-time":"2023-08-24T04:30:03Z","timestamp":1692851403000},"page":"S198-S206","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Radiological Parameters for Gamma Knife Radiosurgery"],"prefix":"10.4103","volume":"71","author":[{"given":"Chirag K.","family":"Ahuja","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameer","family":"Vyas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Parth","family":"Jani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paramjeet","family":"Singh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandeep","family":"Mohindra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narendra","family":"Kumar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manjul","family":"Tripathi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-28-20240907","doi-asserted-by":"crossref","first-page":"402","DOI":"10.1227\/00006123-199203000-00015","article-title":"A comparison between magnetic resonance imaging and computed tomography for stereotactic coordinate determination","volume":"30","author":"Kondziolka","year":"1992","journal-title":"Neurosurgery"},{"key":"R2-28-20240907","doi-asserted-by":"crossref","first-page":"216","DOI":"10.4103\/IJNO.IJNO_431_21","article-title":"Complications of stereotactic radiosurgery: Avoidable or inevitable?","volume":"4","author":"Tripathi","year":"2021","journal-title":"Int J Neurooncol"},{"key":"R3-28-20240907","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1159\/000493068","article-title":"Leksell radiosurgery for the 3 H tumors: Hemangiomas, hemangioblastomas, and hemangiopericytomas","volume":"34","author":"Johnson","year":"2019","journal-title":"Prog Neurol Surg"},{"key":"R4-28-20240907","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1016\/j.radonc.2020.11.014","article-title":"ESTRO ACROP guideline for target volume delineation of skull base tumors","volume":"156","author":"Combs","year":"2021","journal-title":"Radiother Oncol"},{"key":"R5-28-20240907","doi-asserted-by":"crossref","first-page":"826","DOI":"10.4103\/neuroindia.NI_220_17","article-title":"Dose fractionated gamma knife radiosurgery for large arteriovenous malformations on daily or alternate day schedule outside the linear quadratic model: Proof of concept and early results.
