The specific implementation of Gamma Knife treatment can be divided into four steps: installation of the positioning frame, nuclear magnetic positioning, computer simulation, and implementation of treatment. But the expert consultation before treatment and comprehensive treatment after treatment are also very important.
The specific process is as follows: 1. Pre-operative consultation: Special experts in neurosurgery, radiation oncology and neuroimaging are appointed to consult the patient and strictly control the patient for the best treatment effect.
2. Pre-operative signature: The specialist explains to the patient and his family in detail the treatment plan and possible prognosis, and compares the advantages and disadvantages of various treatments. The patient makes a choice and signs a consent form for treatment.
3.Installation of head frame: A frame should be fixed on the patient’s head at the beginning of treatment to facilitate accurate positioning. The patient may experience discomfort at this time, but it is tolerable and takes about 10 minutes.
4.Scanning and positioning: MRI scan of the head is performed to obtain MRI images to clarify the shape, size and location coordinates of the lesion. It takes about 1 hour.
5.Treatment planning: An experienced specialist will clarify the extent of the lesion, select the treatment plan, determine the irradiation dose, etc., and simulate the treatment in the computer. This process takes about 30 minutes, during which the patient is free to move around.
6.Implementation of treatment: The real treatment implementation process does not cause any discomfort to the patient, only the medical staff is repeatedly adjusting the coordinates, the patient only needs to cooperate with sitting up. It takes 30-120 minutes. Treatment can be removed from the head frame, if there is no significant discomfort, 10 minutes to go home to recuperate.
7.Observation follow-up: After gamma knife treatment, there are generally no adverse reactions, the efficacy is also gradually revealed, but still need to regularly review the situation, including symptoms and signs, lesion size and shape, surrounding changes, etc., in order to further treatment.
