Many times, the first inspection report is like a big sieve. If problems are found, a second inspection will be done in detail, but it is not possible to get it right the first time. This is something that ordinary people outside the industry cannot understand. They think that doctors are wasting their time and money.
The reason why ordinary people outside the industry have this perception is that they have raised their self-perception of the threshold for doctors to practice medicine to the point where every doctor is a super boss. Only people in the industry know that the threshold for doctors to practice medicine is just a passing line. It is also impossible for all doctors in tertiary hospitals to be super bosses.
The best radiologists are no different from clinical physicians, and they are a handful in number.
If Xie is able to tell at a glance that the reference lines in this film are not the most accurate, it would require a very horrible level of eyesight. It should be said that Cao Yong can't do it either.
If you don't know how difficult it is to get very accurate positioning with conventional MRI, for example, the positioning principle of MRI is that the center of the scanning part, the center of the coil, and the center of the main magnetic field should be placed at the same horizontal position as much as possible. The word "as much as possible" here is enough to show that it is difficult for ordinary people to do it, and it is difficult for radiologists to get the most accurate.
"I understand." said Tao Zhijie.
Do you really understand? — Cao Yong gave him another look that told him to think more deeply.
Tao Zhijie would not respond to his gaze again. Even if he understood, he had to pretend that he did not understand. Otherwise, what should he do? Should he agree with him that neurosurgery department needs eyes like Xie the most? Should he give her to their neurosurgery department?
In the present case, a second, more detailed examination was necessary, apparently because the results of the first examination had led the doctor to believe that this was necessary.

The purpose of checking again is to avoid making mistakes. And now Xie has already judged that it is very likely that there is a mistake.
"You mean it was missed, right?" Tao Zhijie asked again.
Even if you are not a neurosurgeon, you should have common sense. It is very unlikely that the machine will make a mistake and scan out two larger tumors at the same time.
"Yes, she probably expected that there was something missed." Cao Yong nodded.
Xie Wanying, who was standing nearby, didn't need to say much. She just listened to a big shot like Senior Brother Cao who could explain everything to her clearly even if he couldn't see it.
As mentioned above, if there is a missed diagnosis, you can still use radiotherapy and chemotherapy. However, because the brain has a blood-brain barrier that can greatly reduce the effectiveness of drugs, chemotherapy is not very suitable for brain metastases. It is only limited to a small number of types that are very sensitive to chemotherapy drugs. The medical consensus for multiple brain metastases is that radiotherapy is the first choice.
Radiotherapy is not a simple matter. For example, some doctors who specialize in brain radiotherapy are neurosurgery graduate students and doctoral students who switched to radiology. Therefore, radiotherapy is like treating patients like a clinician, rather than simply doing examinations for clinicians to refer to. The nature can be said to be completely different.
"Two. This number is very important to us neurosurgeons. The doctors who do the MRI examinations are not very clear about what we neurosurgeons think," Cao Yong added.
"I originally thought it was just a matter of whether to have surgery or not." Tao Zhijie was educated by this and responded with inspiration.
Two is a relatively small number. For brain metastases with less than three, we should first consider whether to perform surgery to remove the tumor locally and achieve local cure. Secondly, according to the opinions of neurosurgeons, we know that it is not just a question of whether to perform surgery or not.
