Chapter 1382

The big pig hoof is as stable as ever. It neither ignores the metastasis that is too small to be found, nor gives the specific location of the metastasis.

"Boss Zheng is really busy." Sister Li was not unhappy. She smiled and said, "I was ready to come a few days ago. President Yuan said that you and the people of the Royal Swedish Academy of engineering study basic physics formulas."

"I don't understand. It's to provide some clinical operation experience when making physical models." Zheng Ren said with a smile.

"Can you repeat the test?" Li Lao, standing on one side, asked.

"I can repeat the operation and establish the physical model of the system. The formulas involved are more complex and I don't quite understand." Zheng Ren is honest.

Li nodded.

"Let me introduce you. This is Li Lao, an academician of the Academy of engineering, who has made outstanding contributions to the protection of rare and endangered wildlife in China." Vice President yuan formally introduced: "Li Lao, this is a rising star of our hospital and has won the recommendation of this year's Nobel Prize in medicine."

"Hello, Mr. Li." Zheng Ren bowed and greeted Li Lao respectfully.

"What a rising star. Thirty?" Li Lao asked with a smile.

"Twenty nine."

"What a good age." Mr. Li sighed, "do well. At your age, spring and autumn will be in full bloom in 20 years. Take a promise award and win glory for the country."

Zheng Ren smiled.

Mr. Li understands that people don't ask if they can get it this year. They will get it 20 years later.

"Li Lao, let's go and have a CT." Zheng Ren said.

"Don't worry too much." Old Li smiled and said, "some old friends of the Chinese Academy of Sciences and I have asked. Liver cancer is complicated with metastasis, but we can't find metastatic lesions. This kind of thing is common in clinic, 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. It's just a physical examination."

Li Lao didn't directly refute, but muttered, "I'm not old and confused."

Zheng Ren didn't say anything. It's wrong to say anything at this time.

Vice President Yuan said, "Li Lao, I have something to do on my side, so I won't accompany you. Zheng Ren, after finishing CT, go and report the results to me."

"Yes." Zheng Ren immediately replied.

Old Li waved and said, "Xiao Yuan, you're busy."

It's still early. The patient didn't come up. The machine has been started. Director Chu and several deputy directors came early. Dr. Liang followed at the end and felt some emotion when he saw boss Zheng doing CT for Mr. Li himself.

Zheng Ren wanted to help Li Lao lie down. As soon as he stretched out his hand, he was pushed away by Li Lao, "no, I'm not old."

"Well, that's." Zheng Ren just smiled.

"I understand. I'm a science and technology worker anyway. Don't hide something from me." Li Lao sat on the bed of the CT machine, looked at Zheng Ren and said.

"Don't worry, it's really just an inspection. Didn't you also say that it's unlikely to find the problem." Zheng Ren said with a smile, "check and see if it's OK. I'm not sure."

Li Lao was not satisfied with Zheng renslightly's perfunctory attitude, but he didn't say much, but lay down on the clinic bed.

Director Chu pressed the button, the bed moved inward, and several people went out.

The buzzing sound sounded. The 912 CT machine is very advanced and has little noise.

After sweeping it from head to toe, it took more than 20 minutes. Director Chu and others went to pick up old Li.

Zheng Ren sat in front of the console and devoted himself to making the film. When Li Lao came out, he just stood up and said a word without seeing him off.

Because the system did not give a diagnosis of visceral metastasis, Zheng Ren just went through the viscera and saw that it was all right. The main focus is still on the bones of the whole body, stroking down mm by mm from the skull.

Generally, ect is the main way to check whether there is bone metastasis in bone.

However, this latent metastasis of liver cancer can not be detected by ect or SPECT.

The lesion is too small and has exceeded the technical level of science and technology.

Zheng Ren just wants to try and do his part to an old man of virtue.

"Boss Zheng, can CT see it?" Director Chu sent li away, returned to the CT room, sat next to Zheng Ren and asked.

"Clearly see the location of the lesion, it is unlikely." Zheng Ren said: "but we can know about where there is a problem. In the future, we can focus on monitoring or think of some individual treatment."

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, there were imported CT machines in China. At that time, director Chu was still a student and began to contact early CT.

Up to now, director Chu has been in contact with machines that can scan DNA with CT.

Just want to use such a fine machine to check the whole body, the ability is not great.

Director Chu also thought about Li Lao's condition, but he didn't have a definite idea.

With the existing technology, this is still a blind spot. If you want to determine the diagnosis, you can only wait for scientific and technological progress.

Boss Zheng thinks a little too much. This is the idea of director Chu. His level is high, which director Chu admits. But to find the location of liver cancer metastasis is like a dream.

But it doesn't hurt to try.

Starting from the skull, Zheng Ren squinted at almost frame by frame.

Nearly an hour later, his hand suddenly moved.

After capturing the abnormal signal, Zheng Ren began to rebuild.

Director Chu was almost asleep. When Zheng Ren moved, he cheered up and watched carefully.

Zheng Ren looked at the lower edge of the sixth thoracic vertebra.

In terms of normal bone mineral density, the cross-sectional image of CT is a fence with dense structure. With the emergence and aggravation of osteoporosis, the fence continues to become loose and the load-bearing will gradually decrease.

If there is a disturbance, there may be a compression fracture. For example, sitting at home and squatting, such as a bump on the bus, may become a cause of trauma.

There was no trace of tumor in the image of the console screen. Director Chu looked carefully twice and directly ruled out the possibility of bone metastasis.

The fence here is relatively loose, and there are some images of residual bone trabeculae between the fences.

Looking at the uneven shape, but those scattered bone trabeculae and other things can never be said to be metastases.

"Boss Zheng? I doubt there is a problem here?" Director Chu asked.

"Yes." Zheng Ren nodded and continued to rebuild.

"No, the shape here is relatively normal. I don't see any abnormal images." Director Chu directly denied Zheng Ren's statement.

Although he had a good relationship with Zheng Ren and watched him grow up all the way, Zheng Ren's statement directly denied his technology.

Director Chu is very concerned about this.
