Question 2: What is Gamma Knife? Gamma Knife advantages and disadvantages "Gamma Knife" named "knife", but in fact is not a real scalpel, it is a hemispherical helmet covered with a straight aligner, the helmet can shoot 201 cobalt 60 high-dose ionic rays - gamma rays. It is precisely localized in a certain area, which we call the "target point", by modern imaging techniques such as CT and magnetic **** vibration. Its positioning is extremely accurate, the error is often less than 0.5 millimeters; each gamma ray dose gradient is so large that there is almost no damage to the tissue. However, 201 rays gathered together from different locations can lethally* destroy the target tissue. It is named because it functions like a scalpel, and has the advantages of no trauma, no general anesthesia, no incision, no bleeding and no infection. Second, the principle of gamma knife therapy gamma ray stereotactic radiation therapy system, is a stereotactic technology and radiosurgery technology in one, to treat cranial diseases, mainly stereotactic radiosurgery treatment equipment. It adopts the geometric focusing method of gamma rays, and through precise stereotactic orientation, a certain dosage of gamma rays will be planned to be focused on the pre-selected target point in the body, destroying the tissues in the point in a one-time, lethal manner, so as to achieve the effect of surgical resection or destruction. Normal tissues around the lesion are outside the focal point, and are only irradiated by a single beam of gamma rays, which is very low in energy and free from damage. Like focusing sunlight with a magnifying glass, the heat of the focused spot can ignite objects, while the sunlight outside the focus is safe. Gamma rays instead of scalpel, its therapeutic irradiation range and the normal tissue demarcation is very obvious, the edge of the knife like cut, people figuratively called "Gamma Knife". Gamma knife is divided into head gamma knife and body gamma knife. Head Gamma Knife has static Gamma Knife and rotary Gamma Knife, static Gamma Knife is a number of cobalt source installed in a spherical helmet, so that it focuses on a point in the cranium, rotary Gamma Knife is improved on the basis of the static type, has many advantages, and is a patent of China. Head Gamma Knife can non-invasively eradicate trigeminal neuralgia (trigeminal nerve pain), gliomas, meningiomas, auditory neuromas, pituitary tumors, craniopharyngiomas and so on. Body Gamma Knife is mainly used for the treatment of various tumors in the whole body. 1, benign intracranial tumors such as acoustic neuroma, pituitary tumor and meningioma under 30mm; 2, small and deep intracranial arteriovenous malformations; 3, some benign* tumors that can not be cleanly removed by surgery; 4, smaller and well-defined intracranial metastatic cancers; 5, Parkinson's disease, epilepsy, psychosis and other functional disorders. 1.Routine examination after admission: full-body physical examination, chest radiograph, electrocardiography and electrophoresis. physical examination, chest X-ray, electrocardiogram, blood tests, etc.; 2. Imaging examination: high-speed spiral CT and/or magnetic **** vibration, to exclude intracranial tumors, cerebrovascular disease and other space-occupying lesions, and to provide the basis for performing three-dimensional image fusion.3. Electroencephalogram (EEG): including 32-conductor/16-conductor general EEG, 24-hour EEG, and long-range 128-conductor fully digital EEG monitoring.4. Further elective examinations, if needed Items: magnetoencephalography, functional magnetic **** vibration, magnetic **** vibration spectral analysis, single photon emission computed tomography, positron emission computed tomography Gamma Knife will be the radioactive element "cobalt-60" emitted by the controllable gamma rays, through the geometric focusing, concentrated irradiation of tumor foci, lethal destruction of tumor tissue in the target point, and the destruction of tumor tissue in the target point, and the destruction of tumor tissue in the target point. Gamma Knife can destroy the tumor tissues in the target point to achieve the effect similar to that of scalpel. Gamma Knife is the improvement and development of scalpel in the treatment of tumors, but it cannot replace scalpel. Gamma Knife is a radiation killing treatment, incomplete killing, and the long-term efficacy is far less than that of surgery, so it is suitable for advanced tumors, or those with contraindications to surgery, or those who have lost the chance of surgery, or those who have serious complications, or those who have recurrence or metastasis after surgery. Scalpel can completely remove the tumor under direct vision, which is the first choice for treating early-stage tumors. Gamma Knife is a bloodless procedure that requires no anesthesia or special preparation. On the surface, it seems to be a non-invasive treatment, but in fact, the potential trauma of Gamma Knife should not be underestimated Gamma Knife is a radiation killing therapy, all normal tissues and tumor tissues within the irradiation area will be killed as usual. The larger the irradiation range and the longer the irradiation time are, the larger the killing and wounding of normal tissues will be, especially to the vital organs, which will be hit even more; Gamma Knife will cause a series of radiological reactions such as hair loss, nausea and vomiting, fatigue, and pain, Gamma knife will also cause a series of radiation reactions during or after irradiation, such as hair loss, nausea, vomiting, fatigue, reduction of white blood cells, platelets and even whole blood cells, etc., and in serious cases, it will also cause radiation sickness which is difficult to be treated; Gamma rays will also interfere with and destroy the normal immune function of the human body, which is undoubtedly worse for the tumor patients. Some tumors disappear quickly after gamma knife treatment. However, the short duration of the tumor, the recurrence in a few months, and the rapid deterioration and death may be related to the low immune function.
Question 3: What is Gamma Knife surgery? It is generally used for cerebrovascular and neurological systems, and is performed with gamma rays, which is characterized by high precision and safety!
Question 4: How much does Gamma Knife surgery cost? Gamma Knife treatment is usually about 1-3 million dollars. Gamma Knife is not a real scalpel, but a very advanced radiation therapy equipment, whose full name is: Gamma Ray Stereotactic Therapy System. It irradiates many beams of very fine gamma rays through the body from different angles and directions, and causes them all to converge at one point to form a focal point. As the dose of each beam of radiation is very small, basically will not cause damage to the human tissue it traverses, as long as the focus on the lesion, you can accurately like a scalpel to destroy the lesion at once, to achieve the miraculous efficacy of non-invasive, non-bloody, non-infectious, painless, rapid, safe and reliable.
But the treatment of gamma knife and chemotherapy will have some side effects, which can be combined with the treatment of traditional Chinese medicine, traditional Chinese medicine now Xingxun (ginsenoside Rh2) capsule can reduce the patient's symptoms, alleviate the side effects of the radiotherapy process, improve the quality of life.
Question 5: What is the Gamma Knife Gamma Knife, also known as stereotactic gamma ray radiation therapy system, is a fusion of modern computer technology, stereotactic technology and surgical technology in one of the therapeutic equipment, it will be cobalt-60 gamma rays issued by the geometric focusing, focused on the lesions, a one-time, lethal destruction of the target point of the tissue, and the rays of the normal tissues through the human body is almost harmless, and the dose is sharply reduced, so its treatment. And the dose is sharply reduced, so its therapeutic irradiation range and the boundaries of normal tissue is very obvious, the edge of the knife like cut, people image called "Gamma Knife".
Question 6: What is Gamma Knife therapy? Gamma Knife is not really a scalpel, but also a radiation therapy, its full name is stereotactic gamma ray radiation therapy system, is a blend of modern radiophysics, radiobiology, medical imaging, computers, intelligent automated control and other disciplines in one of the modern large-scale high-tech medical equipment, which uses the radioactive element 60Co radiated r rays in a geometric focusing mode, through a precise three-dimensional Through precise three-dimensional orientation, a certain dose of gamma rays is planned to be irradiated on the tumor to destroy the tumor tissue with a one-time lethal dose, so as to achieve the same effect as surgical resection or local destruction. Due to the rotational focusing of the rays, the normal tissues of the human body are only exposed to instantaneous, almost harmless irradiation, and the dose is sharply reduced, so its therapeutic irradiation range and the normal tissue boundaries are very obvious, and the edges are as neat as a scalpel cut, so it is imaginatively called the Gamma Knife.
The principle of Gamma Knife treatment is similar to the focusing process of a magnifying glass. When the magnifying glass is placed in the sunlight, the spot under the magnifying glass will become a dazzling spot of light, which is the focal point. Outside of the focus, the sensation is normal, but at the focal point there is a high level of heat, enough to set some objects on fire. Thus, the radiation dose is focused on the tumor area so that the tumor receives a dose sufficient to kill the tumor, thus achieving the desired therapeutic effect.
However, Gamma Knife is not a complete replacement for surgery or traditional oncology, it is more suitable for treating regular shaped and relatively small tumors. Therefore, for liver cancer, Gamma Knife is suitable for small liver cancers that cannot be surgically resected or locally ablated.
