What is the negative effect of Super Gamma Knife on the human body?

Hello, the effect of Gamma Knife on the head such as brain tumor** is OK, but the effect of the body** is not good.

The effect of pancreatic cancer in the advanced stage is not good, and it is best to choose stereo radiosurgery** - CyberKnife.

Any kind of medical device will have some impact on the patient to a greater or lesser extent, but the impact of Gamma Knife** is the least slight.

Gamma Knife is a stereoscopic radiation**, which uses gamma rays to focus to form a small sun in the body, and a spherical target of a corresponding radius fills the tumor tissue. Due to the lack of real-time tracking technology of IGRT in Gamma Knife, the body tumor will be displaced with the respiration or peristalsis of the organs, causing the target to deviate from the tumor area and killing normal tissues.

However, there is a medical theory that one centimeter around the tumor boundary belongs to the subclinical boundary, so for the body** (including pancreatic cancer), the following parameters are involved:

1.Collimator model size This parameter will directly affect the accuracy.

2.Dose size This is the most direct and important parameter for the tumor.

As far as I know, the collimator model of the Super Gamma Knife does not seem to meet the national standard, and at the same time, its dosage is only, not very ideal.

Another disadvantage of Super Gamma Knife is mainly in its mechanical structure. Its **cabin is not large enough, **space is limited. At the same time, it is easy to get stuck when entering the bed, which will lead to the consequences of the patient's arm being broken.

I don't know much about the others, I seem to have seen this information before, and I heard that the best gamma knife now is the whole body knife of Shenzhen Shengai Company, and the radiotherapy equipment of Sweden Ekeda University. However, it seems that Elekta did not develop the Gamma Knife for the body. For details, you can check the Gamma Knife centers of the above two companies on the Internet, and then make a decision in detail.

Good luck to your father soon**

Many friends should not know about gamma knife, gamma knife is a way of radioactivity, usually patients with tumors will use gamma knife to perform**. Gamma Knife can be divided into two types: Head Gamma Knife and Body Gamma Knife, which are two ** methods for body parts and head respectively. So does Gamma Knife have an effect on our body?

Let's take a look!

1. Gamma knife is a kind of radiotherapy, and there will be some radiation reactions during or after mapping, such as dizziness, transient headache, nausea and vomiting, fatigue, leukopenia, etc., which can generally be recovered after symptomatic treatment.

2. Gamma knife rays will penetrate the normal tissues of the human body, and the small dose will not cause damage to the normal tissues of the human body, if the application is improper, the irradiation dose is large, and the irradiated tissues may be burned, and the scarring of the tissues after the burns will continue to shrink and ossify, and they will not repair themselves, and will continue to progress, causing the corresponding reaction of the surrounding unburned tissues.

3. A small number of patients may have complications such as radiation cerebral edema or necrosis within 3 to 18 months after **. Therefore, once the symptoms worsen or new symptoms appear after Gamma Knife**, you should return to the doctor in time.

4. Gamma Knife can not kill the hidden tumors hidden in the dead corner, can not completely kill tumor cells, and has a relatively poor effect on tumors in important functional areas of the brain such as thalamus, brainstem and other parts.

Radiotherapy reactions such as transient headache and dizziness may occur early (within a few hours), and can be recovered with symptomatic treatment**. In addition, regarding the comorbidity of the Gamma Knife *****. Compared with surgery, the proportion of complications after Gamma Knife ***** is indeed relatively low.

Through the above introduction, I believe we all already know that the use of gamma knife will still have some impact on our body, which are normal manifestations of radiation reactions. Such as dizziness, nausea and vomiting, weakness of limbs, etc., these accompanying symptoms will slowly disappear after **, and only a small number of people will have symptoms of cerebral edema or necrosis.

1. Gamma Knife** is highly accurate, safe and reliable, and has no abnormal damage and few complications to the normal brain tissue around the lesion and various systems of the body.

2. Gamma Knife can be used for most parts of the brain, especially for inoperable lesions in the deep brain or important nerve functional areas.

3. Time-saving and simple, patients only need to do the necessary physical examination and examination before **. No surgery, no trauma, no bleeding, **bitter. **It only takes 10 minutes at a time, and the combined time of the whole treatment is only 1-2 hours.

**After 1 day of observation, they can be discharged, and the patients who accept ** generally do not affect their work and study.

4. The combination of Gamma Knife and other methods of neurosurgery enables a variety of cranial diseases that cannot be achieved by a single method. In order to minimize the risk and sequelae.

There are definitely complications that can be minimized with any invasive ** if the doctor is good.

The effect of the small meningioma on the gamma knife ** screen (the diameter of the upright wisdom is less than 3cm) is very good, not worse than the surgery, and there is basically no parapositive response effect or sequelae. However, the effect of slightly larger tumors is not ideal, it is better to do surgery, and the effect of gamma knife is definitely positive if it is residual or ** after surgery! For meningioma tumors less than 3cm under the tentorial, the effect can also be used, which is easy to produce cerebral edema and nausea, headache and other symptoms, but timely infusion of mannitol and hormones can be prevented and controlled.

Gamma Knife is a precise stereotactic ** hand system, the positioning is quite accurate, and the radiation only irradiates the tumor and has almost no damage to the surrounding normal tissues. Therefore, the use of gamma knife ** tumor will not produce any sequelae, that is, some tumors may have side effects such as cerebral edema, which will disappear after symptomatic**.

There is *** in both the saber ** and the general radiation**, and he may have radiation pneumonia-like changes. In the event of radiation pneumonia, there is no corresponding general method in the world, and only antibiotics can be relied on or disturbed.

The central ** theory holds that pain is caused by abnormal electrical discharges in the trigeminal spinal nucleus or elsewhere in the center; The theory of peripheral ** suggests that the posterior root part of the pontine brain from the half-moon node to the pontine brain leads to trigeminal nerve root ischemia and nerve demyelination lesions, and impulse conduction abnormalities lead to pain.

The application of gamma knife ** trigeminal neuralgia is to locate through imaging, transmit MRI images to a computer workstation, calculate the three-dimensional coordinates of the trigeminal nerve root, formulate a ** plan, determine the dose of gamma rays, and then concentrate the precisely focused gamma rays on the trigeminal nerve root target to block the conduction of pain fibers, and the function of touch and motor nerve fibers is not affected. According to the best experience at home and abroad, the trigeminal nerve root into the pontine segment is generally selected as the irradiation target, and the trigeminal neuralgia caused by peripheral lesions or central lesions can be achieved.

If in doubt, call the account number**.

Hello: Gamma Knife is a bloodless surgery that requires no anesthesia and no special preparation. On the surface, it seems to be non-invasive**, but in fact, the potential trauma of the gamma knife cannot be underestimated Gamma knife is a radioactive killing**, all normal tissues and tumor tissues in the irradiation area are killed, the larger the irradiation range, the longer the irradiation time, the greater the damage to normal tissues, especially for living organs, the blow is even worse; Gamma Knife can also cause a series of radiation reactions during or after irradiation, such as hair loss, nausea and vomiting, fatigue, leukopenia, platelets and pancytopenia, etc., and in severe cases, it also leads to lead disorder and difficult radiation sickness; Gamma rays can also interfere with and destroy the normal immune function of the human body, which is undoubtedly worse for cancer patients.

It is recommended that patients use Chinese medicine to counter the gamma knife to the patient***, I wish you good health.
