What is the Craniospinal axis?
The entire craniospinal axis (CSA) is treated when tumor cells are carried within the cerebrospinal fluid. Because of Patterson and Farr’s understanding of seeding, they treated the CSA as a single volume with radiation, starting in 1941. 2. CSA radiation treatment (RT) is complicated by the total length of the CSA.
What does Craniospinal mean?
[ krā′nē-ō-spī′nəl ] adj. Relating to the cranium and the spinal column.
What is the purpose of Craniospinal irradiation?
Craniospinal irradiation procedure is required to kill the tumour cells in the brain and spinal cord after tumours such as Ependymomas and Medulloblastomas spread into the whole brain.
What is a Craniospinal treatment?
Craniospinal irradiation (CSI) is a radiation technique used for patients with central nervous system malignancies, such as medulloblastoma and primitive neuroectodermal tumors.
What is CSI patient?
Use of the Central Sensitization Inventory (CSI) as a treatment outcome measure for patients with chronic spinal pain disorder in a functional restoration program.
How does total body irradiation work?
Total body irradiation (TBI) Radiotherapy to the whole body is called total body irradiation or TBI.
What does radiation do to brain tumors?
Radiation is a powerful weapon against cancer cells, but sometimes it kills healthy brain tissue as well. This severe side effect is called radiation necrosis. Necrosis (a late effect of high doses of radiation) can cause headaches, seizures, or even death in a small number of cases.
How does palliative radiotherapy work?
Radiotherapy to relieve symptoms is also known as palliative radiotherapy. Palliative radiotherapy aims to shrink cancer, slow down its growth or control symptoms. It doesn’t aim to cure cancer. Depending on the type of cancer you have, and where it has spread to, you might have external or internal radiotherapy.
What does CSI stand for in healthcare?
Background context: The Central Sensitization Inventory (CSI) is a valid and reliable patient-reported instrument designed to identify patients whose presenting symptoms may be related to central sensitization (CS).
What does CSI mean?
Crime scene investigator
Crime scene investigator, a person who investigates crime scene evidence.
How is the gantry angle of the craniospinal field rotated?
Additionally, the gantry angle of the cranial fields can be rotated in an anterior-posterior fashion by approximately 5° to create a light posterior oblique field in order to spare the contralateral lens in younger patients (Fig. 27.3d ).
How is table angle used in craniospinal irradiation?
A modified table angle can additionally be used to account for caudal divergence of the craniocervical fields. This is done by rotating the couch towards the gantry by the following angle, where SAD = source to axis distance of the lateral cranial fields (Fig. 27.3c ):
How is craniospinal radiation used to treat brain tumors?
Although craniospinal radiotherapy continues to be a component of standard therapy for older children with tumors prone to neuraxis spread, such as medulloblastoma, radiation for most other tumors, if indicated, is administered only to the tumor and a margin of surrounding brain.
Where is the lower border of the Cranial Field placed?
The lower border of the cranial field should be placed in the lower cervical spine superior to the shoulders so as to avoid interference and should be collimated to match the divergence of the upper spine field. The angle of collimation can be found by the following equation (Fig. 27.3b ):
