Big Pig Hoof is as stable as ever. It neither ignores metastases that are too small to detect nor gives the specific location of metastases.
"Boss Zheng is really busy." Sister Li was not unhappy and said with a smile: "I was planning to come here a few days ago. Dean Yuan said that you and the people from the Royal Swedish Academy of Engineering will study basic physics formulas."
"I don't understand either. It's just to provide some clinical surgical experience when making physical models." Zheng Ren said with a smile.
"Can the test be repeated?" Mr. Li, who was standing aside, asked.
"I can repeat the surgery. I am still studying the establishment of a physical model of the system. The formulas involved are relatively complicated and I don't understand them well." Zheng Ren said frankly.
Mr. Li nodded.
"Let me introduce, this is Mr. Li, an academician of the Academy of Engineering, who has made outstanding contributions to the protection of rare and endangered wild animals in our country." Vice President Yuan introduced formally: "Mr. Li, this is our The hospital’s rising star has been recommended for this year’s Nobel Prize in Medicine.”
"Hello, Mr. Li." Zheng Ren bowed and greeted Mr. Li respectfully.
"What a rising star. Are you thirty?" Mr. Li asked with a smile.
"Twenty-nine."
"What a good age." Mr. Li sighed with emotion, "Work hard. At your age, you will still be in your prime in twenty years. You will win a Nobel Prize and bring glory to the country."
Zheng Ren smiled.
Teacher Li understands people. They didn’t even ask if they could get it this year. They just jumped to 20 years later.
"Mr. Li, let's go and do a CT scan." Zheng Ren said.
"You don't have to worry too much." Mr. Li smiled slightly and said: "I and some old guys from the Chinese Academy of Sciences have asked, it is common in clinical practice that liver cancer metastasizes but cannot find the metastatic lesions, but there is no good way. "
"Dad, what are you talking about?" Sister Li said angrily, "It's not a transfer at all. There's nothing wrong with it. It's just a physical examination."
Mr. Li did not directly refute, but muttered to himself, "I'm not stupid."
Zheng Ren didn't say anything. Anything he said at this time was wrong.
Vice President Yuan said: "Mr. Li, I still have something to do, so I won't accompany you. Zheng Ren, after you finish the CT scan, report to me if you have the results."
"Yes." Zheng Ren replied immediately.
Mr. Li waved his hand and said, "Xiao Yuan, go ahead and get busy."
It was still early and the patient didn't come up. The machine has been turned on, and Director Chu and several deputy directors came early. Dr. Liang followed at the end and felt a little emotional when he saw Boss Zheng performing a CT scan on Mr. Li himself.
Zheng Ren wanted to help Mr. Li lie down, but as soon as he stretched out his hand, Mr. Li pushed him away, "No, I'm not old yet."
"Yeah, that's right." Zheng Ren just smiled.
"I understand that you are a scientific and technological worker after all, so don't hide anything from me." Mr. Li sat on the bed of the CT machine and looked at Zheng Ren and said.
"Don't worry, it's really just an inspection. Didn't you also say that it is unlikely to find the problem." Zheng Ren said with a smile: "Let's check it out. I'm not sure whether it will work."
Mr. Li was very dissatisfied with Zheng Ren's perfunctory attitude, but he didn't say much and lay down on the examination bed.
Director Chu pressed the button, the bed moved inward, and several people walked out.
There was a buzzing sound. The 912 CT machine was very advanced and not very noisy.
After scanning from head to toe for more than 20 minutes, Director Chu and others went to pick Mr. Li out.
Zheng Ren was sitting in front of the operating table, concentrating on making the movie. When Mr. Li came out, he just stood up and said a few words without seeing him off.
Because the system did not give a diagnosis of visceral metastasis, Zheng Ren just checked the internal organs and let it go if nothing happened. The main focus is still on the bones of the whole body, starting from the skull and working down millimeter by millimeter.
Under normal circumstances, ECT is the main way to check the bone quality for bone metastasis.
However, this latent metastasis mode of liver cancer cannot be detected by either ECT or PECT.
The lesions are too small and have exceeded the technical level of existing technology.
Zheng Ren just wanted to try and do his part for an old and virtuous old man.
"Boss Zheng, can CT tell?" Director Chu sent Mr. Li away, returned to the CT room, and sat next to Zheng Ren and asked.
"It's unlikely that we can clearly see the location of the lesion." Zheng Rendao: "But we can roughly know where the problem is. We can focus on monitoring in the future, or think of individual treatments."
Director Chu smiled and shook his head. He has been doing CT for thirty or forty years.
In 1972, British scientists successfully developed the first CT machine. In the 1980s, imported CT machines were available in China. At that time, Director Chu was still a student and began to come into contact with early CT.
Until now, Director Chu has been exposed to the machine that can perform CT scans on DNA.
If you just want to use such a sophisticated machine to examine your whole body, it's not very possible.
Director Chu also had thoughts about Mr. Li's condition, but he had no definite idea.
With current technology, this is still a blind spot. If you want to confirm the diagnosis, you can only wait for scientific and technological progress.
Boss Zheng is thinking a little too much. This is Director Chu’s idea. His level is high, Director Chu admitted. But trying to find the location of metastatic lesions of liver cancer is tantamount to wishful thinking.
But it never hurts to give it a try.
Starting from the skull, Zheng Ren squinted and looked at the images carefully, almost frame by frame.
Nearly an hour later, his hand suddenly moved.
After catching the abnormal signal, Zheng Ren began to rebuild.
Director Chu almost fell asleep while watching. When Zheng Ren started to move, he cheered up and watched carefully.
The level Zheng Ren looked at was the lower edge of the sixth thoracic vertebra.
For normal bone density, the cross-section of CT looks like a fence with a relatively dense structure. As osteoporosis occurs and worsens, the fence continues to become looser and the load-bearing capacity will gradually decrease.
If there is any disturbance, a compression fracture may occur. For example, sitting at home and squatting, such as a bump on the bus, may become the cause of trauma.
There was no trace of any tumor in the image on the console screen. Director Chu looked at it carefully twice and directly ruled out the possibility of bone metastases.
The fence here is relatively loose, and there are some residual bone trabeculae and other images between the fences.
It looks uneven in shape, but those sporadic bone trabeculae and the like cannot be said to be metastases.
"Boss Zheng? Do you suspect there is a problem here?" Director Chu asked.
"Yes." Zheng Ren nodded and continued to rebuild.
"No, the shape here is relatively normal and no abnormal images were seen." Director Chu directly denied Zheng Ren's statement.
Although he has a good relationship with Zheng Ren and has watched him grow up, Zheng Ren's statement directly denies his own skills.
Director Chu is very concerned about this.
