  Student Wei, who was a bit of a scumbag, was different. He couldn't understand and then asked the students around him in a low voice: "What do you mean?"

   This time, Geng also didn’t quite understand.

  When you come to neurosurgery for an internship, you usually think about how to learn how to do neurosurgery. Radiation therapy is another type of specialty, not the practice of surgeons. If you don't want to study in the past, you don't want to preview and study in advance, unless you want to transfer to a career.

   Similarly, there is classmate Pan, a top student, who doesn't know what to ask.

  At this time, the three students really admired classmate Xie, who knew everything.

  Before rebirth, she had been in the medical circle for many years. It is impossible not to know the hot content in the medical circle. She is not a rookie medical student in essence, she is just eating the benefits of rebirth again. Xie Wanying is self-aware.

  Simply put, if you are in the future, it is easy to know that patients with brain metastases and their families ask doctors the most about the use of Gamma Knife, accelerators or cyberknife for brain metastases.

  In this era, as Brother Cao said next:

   "If radiotherapy is done abroad, it is not the whole brain radiotherapy that is often done in China."

  Radiotherapy for brain metastases can be roughly divided into whole brain radiotherapy (WBRT) and stereotactic radiosurgery (SRS).

  Because many domestic machines are not good enough, advanced enough, positioning is not accurate enough, it is difficult to do precise radiotherapy, and it is easy to relapse and be complained by patients after the treatment. The biggest flaw of whole brain amplification is that the doctor used the most powerful means at once.

  Clinical treatment guidelines can be compared to the principle of using antibiotics. If you are not sure that you can wipe out all the gods of death, you can’t use all the trump cards, you have to take them one by one.

   "The whole brain is put to foreign countries for the last use, unless some special transfers cannot use SRS, such as transfers to the meninges."

   "Is the whole brain put too much damage?"

"Yes."

  The whole brain is to kill healthy cells and cancer cells together, the result can be imagined, you can kill once, but what to do if you kill more healthy cells of patients, brain cells are difficult to grow.

  Speaking of cold knowledge, radiotherapy, such as neurosurgery, may not alleviate the patient's symptoms and may aggravate the patient's symptoms, because if the healthy nerve cells are killed during the treatment, some of the patient's brain may malfunction. Therefore, a good radiotherapy doctor will not give the first choice to the whole brain.

  If you want to do surgery only on the lesion, it is targeted radiosurgery. This kind of radiation therapy is similar to precise minimally invasive surgery, and many terms have taken the surgical name of knife instead of radiation therapy.

  What kind of knife, what kind of knife, let ordinary people mistakenly think that the machine held by the radiation doctor is holding a scalpel. Not at all, actually, just radiation therapy.

   "If you say that, are there many options for radiotherapy?" Tao Zhijie recalled what he knew, and couldn't help frowning, "It seems that our hospital doesn't have what you said?"

   Guoxie currently has no stereotaxic surgical equipment. On this point, Cao Yong admitted that Dean Wu's stinginess may have prevented many new equipment from being introduced to the National Association of China.

  However, if you ask Dean Wu himself, Dean Wu thinks that he should not take the blame.

  Introducing the latest international medical equipment is a matter that cannot be clapped.
