"Huh?" Director Chen was stunned for a moment.
Zheng Ren held the patient's CT film in his hand, and countless thoughts were flying in his mind.
In the ruins of Nanchuan Town, the operation between life and death made him come into contact with the big shackles of technology, and he unintentionally broke these shackles.
Although it was only reflected in the surgery for the time being, Zheng Ren knew that his ability to read pictures would definitely change dramatically.
When I was undergoing surgery at Pengxi Township Hospital, every time I saw the patient's X-ray, more relevant information could not help but pop up in my mind.
If it weren't for the countless wounded waiting for treatment on the front line, Zheng Ren would have been unable to restrain his curiosity and ponder it.
At this time, facing a patient with abdominal pain, the film Zheng Ren saw was different from the fragment that appeared in his mind.
The CT films were simplified, turned into data, and then integrated in the mind to become what Zheng Ren wanted.
Because Zheng Ren saw the patient's diagnosis, the load to complete all this was not heavy. He immediately found the abnormal points in the film and found the problem.
Looking at the CT image in front of me, there are only a few vague abnormalities. If you don’t identify it carefully, this is an ordinary CT image of retroperitoneal hematoma. And that little bit of abnormality can be judged as fat shadow or artifact.
However, when Zheng Ren watched the CT film now, it was a different scene.
Su Yun came over, frowned and asked, "Boss, I think this film is fine."
Director Chen was also very strange, but he didn't say anything. The experience in Nanchuan Town made him realize how special this young doctor was. Otherwise, he wouldn't have made a special call to ask Zheng Ren to come over.
"Su Yun, look..." Zheng Ren said, suddenly remembering something, and immediately said: "Director Chen, the micro-pump is used to reduce blood pressure and control the patient's blood pressure. The patient is in severe pain, so give 5 mg of morphine first."
Zheng Ren said it very politely, but his confident expression and tone that could not refuse were the standard posture of a superior doctor.
Although Director Chen was confused, he did not refuse. He immediately called the nurse and gave 5mg of morphine as Zheng Ren said, then installed a micropump and pumped sodium nitroprusside intravenously to control blood pressure.
Now the patient cannot be moved, and Zheng Ren is in a hurry and there is nothing he can do.
Although the blood pressure on the ECG monitoring is not high, there is still the possibility of a sudden increase in blood pressure during movement, which could break the abdominal aorta.
Be sure to control your blood pressure first.
This is similar to the first time he went to the imperial capital and encountered Cui Heming's thoracic aortic dissection on the plane.
It's just that now there are micropumps and various drugs, and everything is much better than the conditions on airplanes before.
Seeing that the other side was busy and the operation would not be performed for a while, Su Yun refused, grabbed Zheng Ren and asked: "How did you tell? Anyway, the patient cannot be moved for the time being, so hurry up and talk about it."
Zheng Ren nodded and walked to the doctor's office carrying the film.
The reader was on, with two films inserted into it.
Zheng Ren packed up the films inserted in the reader, found the film bag according to the time and name in the upper right corner and put it away, and then inserted the abdominal CT scan of the patient with abdominal pain into the reader.
"Here, look carefully." Zheng Ren said: "It looks normal, like a normal blood vessel structure. But do you feel that the density is different from the surrounding blood vessels?"
He pointed at a point in the film and said firmly.
Su Yun stared at the position of Zheng Ren's finger with a strange expression.
"That's right, you arrange the pixels according to a digital matrix, and you reverse it. Uh... It's indeed a bit difficult, can you imagine?"
Su Yun glanced at Zheng Ren and said disdainfully: "Are you saying that the digital matrix goes through a digital converter, converting each number into pixels ranging from black to white, ranging in grayscale, and arrange them according to the matrix?"
This is the basic principle of CT imaging, and Su Yun certainly understands it. But if you go the other way around... what do you get
"If you know, just give it a try, and in turn, get the most original data, and then convert it again according to 64-slice CT three-dimensional imaging."
"..." Su Yun was stunned.
Transformed in this way, the human brain is regarded as a machine, and it is also a high-frequency machine.
Is this something humans can do
The arrogance in his eyes turned into countless doubts. He looked at the film inserted in the reader and was speechless for a long time.
Director Lao Chen also followed after arranging the nurse's work.
He was curious about how Zheng Ren made the diagnosis.
As an old imaging worker, when Director Chen was young, the hospital imported a machine and had to repair it himself if it broke.
Therefore, he understood what Zheng Ren said more thoroughly than Su Yun.
It’s just... is this okay
"Dr. Zheng, have you constructed a 64-slice CT three-dimensional imaging in your own brain?" Director Chen asked doubtfully.
"It's not that exaggerated." Zheng Ren said with a smile: "It would be difficult to reconstruct all the data. But if we only limit ourselves to this point, the data that needs to be reconstructed will be much less, and it will be relatively simple."
Director Chen thought to himself, is it so powerful? In my opinion, it is absolutely impossible to do, but Dr. Zheng only said that it is difficult, not that it is completely impossible!
"I understand!" Su Yun slammed the table in front of the reader and said loudly: "Here is an intima fault!"
"Yes." Zheng Rendao: "When the injury occurred, the blood pressure increased and the lining of the blood vessel ruptured. But immediately due to heavy bleeding, the blood pressure dropped, and there was no major problem with the lining of the blood vessel. After the intervention, the bleeding All the blood vessels are embolized, and the patient's blood pressure gradually rises, causing the ruptured intima of the abdominal aorta to start tearing again."
"Boss, I remember you knew it after just one glance." Su Yun was a little confused. The diagnosis was correct. He even thought that what Zheng Ren said was all nonsense.
The key point is that Zheng Ren restores the CT images to the original data and then reconstructs it. This speed is simply too fast!
Moreover, Su Yun's biggest doubt was not asked. That's how Zheng Ren judged that there was a problem at that point.
Zheng Ren pointed out the location, and he had to do mental calculations for a long time to restore and rebuild it. And this guy brought the film and casually said he needed emergency surgery.
What a monster, Su Yun thought to himself.
"I've watched too many movies, and I feel it." Zheng Ren said casually.
Although Director Chen knew it, he was too old and his brainpower could no longer do such complex calculations as he could when he was young.
According to the normal procedure, the patient needs to be taken to the CT room for a vascular CTA examination before the diagnosis can be confirmed. After the diagnosis is confirmed, the surgical drape is lifted and a stent is placed in the patient's abdominal aorta to solve the problem.
Before interventional surgery, aortic dissection was a serious and fatal disease. With interventional surgery, as long as it can be diagnosed, except for type 1 aortic dissection, it is a minor problem.
As long as interventional angiography is performed, the location of the arterial dissection can be seen on the image, and there is no need to perform three-dimensional reconstruction of the blood vessels.
But this needs to be based on correct diagnosis.
Director Chen hesitated.
