The big pork trotter was still as stable as ever. They did not ignore the metastasis that was so small that it could not be detected, and they did not give the specific location of the metastases.

“Boss Zheng, you’re so busy.” Sister li wasn’t unhappy. She smiled and said,”I was about to come a few days ago. President Yuan said that you and the people from the Royal Sweden Academy of Engineering were studying basic physics formulas.”

“I don’t know either. I’m just providing some Clinical Surgery experience while I’m building the physical model.” Zheng Ren said with a smile.

“Can you repeat the experiment?” Elder li, who was standing at the side, asked.

“I can repeat the surgery, and I’m still working on the physical model of the system. The formulas involved are quite complicated, and I don’t quite understand them.” Zheng Ren was honest.

Old man Li nodded.

“Let me introduce you. This is elder li, an academician from the Chinese Academy of Engineering. He has made an outstanding contribution to the protection of rare and endangered wild animals in our country.” Vice President Yuan introduced him formally,””Elder li, this is the rising star of our hospital. He was recommended by the Nobel Prize in Medicine this year.”

“Hello, old Li.” Zheng Ren bowed and greeted elder li respectfully.

“He’s really a rising star. Thirty?” Old man Li asked with a smile.

“29.”

“What a good age.” Elder li was a little emotional.”Do a good job. At your age, you’ll still be in your Prime in 20 years. At that time, you can win a Nobel Prize and bring glory to the country.”

Zheng Ren laughed.

Teacher li was an understanding person. He didn’t even ask if he could get it this year and directly talked about 20 years later.

“Elder li, let’s go. Let’s do a CT scan.” Zheng Ren said.

“There’s no need to waste too much energy. ” Elder li smiled.”I’ve asked some of the old guys at the Chinese Academy of Sciences. Liver cancer with metastasis but not being able to find the metastasis is a common occurrence in the clinical world. However, there’s no good solution.”

“Dad, what are you saying?” Sister Li said unhappily,”it’s not a transfer at all. There’s nothing wrong. It’s just a physical examination.”

Elder li didn’t refute him directly. He just mumbled to himself,”I’m not old and muddle – headed.”

Zheng Ren didn’t say anything. Anything he said now would be wrong.

“Elder Li, I still have something to do, so I won’t be able to accompany you,” said Vice President Yuan. Zheng Ren, report to me when you’re done with the CT scan. ”

“Yes.” Zheng Ren immediately replied.

“Little Yuan, you can go now.” Old man Li waved his hand.

It was still early, and the patient had not come up yet. The machines were already turned on. Department Director Hao and a few associate department directors had arrived early. Professor Liang was at the back. He felt a little emotional when he saw boss Zheng doing a CT scan for elder li.

Zheng Ren wanted to help elder li lie down, but he was pushed away by elder li the moment he reached out.”No need, I’m not old yet.”

“Yes, yes, that’s true.” Zheng Ren only smiled.

“I understand. I’m still a scientist after all. Don’t hide anything from me.” Elder li sat on the bed of the CT scan machine and looked at Zheng Ren.

“Don’t worry, it’s really just an examination. Didn’t you say it yourself? the possibility of finding the problem isn’t high. ” “I’ll check it out,” Zheng Ren said with a smile.”I’m not sure if it’ll work.”

Elder li was very dissatisfied with Zheng Ren’s perfunctory attitude, but he didn’t say much. Instead, he lay down on the bed.

Department Director Yan pressed a button, and the bed moved inward. The few of them walked out.

The 912 CT scan machine was very advanced and did not make much noise.

He scanned the patient from head to toe, and after about twenty minutes, Department Director Hao and the others went to pick up old Li.

Zheng Ren, on the other hand, sat in front of the operating table and focused on the x – ray. When old Li came out, he just stood up and said a few words. He didn’t go to see him off.

As the system did not give a diagnosis of internal organ metastasis, Zheng Ren only checked the internal organs once and let it go when he saw that they were fine. His main attention was still on the bones in his entire body. He started from the skull and cut down millimeter by millimeter.

Normally, ECCT was the main way to check if there was bone metastases in the bone.

However, the latent metastasis from liver cancer could not be detected by ECTS or ePCT.

The cause of the illness was too small, and it had already exceeded the technological level of current technology.

Zheng Ren just wanted to try and do his part for an old man of honor.

“Boss Zheng, can you tell from the CT scan?” After sending elder li off, Department Director Hao returned to the CT scan room and sat next to Zheng Ren.

“The possibility of him being able to see the location of the lesion clearly is not high.” “But we can roughly know where the problem lies,” Zheng Ren said.”We can focus on monitoring it in the future, or think of other ways to treat it.”

Department Director Yan smiled and shook his head. He had been doing CT scans for thirty to forty years.

In 1972, United Kingdom scientists successfully developed the first CT machine. In the 1980s, there were already imported CT machines in China. At that time, director Hao was still a student, and he had already begun to come into contact with early CT scans.

Up until now, Department Director Hao had been in contact with a machine that could perform a CT scan for DNA.

However, it was not possible to use such a fine machine to check his whole body.

Department Director Hao had some thoughts about elder Li’s condition, but he did not have a definite idea.

With the current technology, this was still a blind spot. If he wanted to make a diagnosis, he could only wait for technology to improve.

Boss Zheng was overthinking things. This was what chief Kuang thought. He was indeed very skilled, and director Yan admitted that. However, it would be a fool’s dream to find the location of liver cancer metastasis.

But there was no harm in trying.

Starting from the skull, Zheng Ren squinted his eyes and looked at the image frame by frame carefully.

After nearly an hour, his hand suddenly moved.

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

Director Kuang almost fell asleep as he watched. When Zheng Ren started to move, he perked up and watched carefully.

Zheng Ren was looking at the lower edge of the sixth thoracic spine.

In terms of normal bone density, the cross – section of a CT scan was like a fence, and its structure was relatively compact. With the appearance and aggravation of osteoporosis, the fenced area would continue to become looser, and the load bearing would gradually decrease.

Even the slightest movement could cause a compressive fracture. For example, sitting at home or a bumpy ride on the bus could be the cause of trauma.

There was no sign of a tumor in the image on the screen of the operating table. Department Director Hao looked at it carefully twice and ruled out the possibility of bone metastasis.

The bars here were relatively loose, and there were some images of residual bone beams between the bars.

The shape of the tumor was uneven, but there were spots of bone structure, so it could not be considered a metastasis.

“Boss Zheng? Are you suspecting that there’s a problem here?” Director Yan asked.

“Yeah.” Zheng Ren nodded and continued with the reconstruction.

“It won ‘t. The form here is normal. I don’t see any abnormal images.” Department Director Yan immediately denied Zheng Ren’s statement.

Although he had a good relationship with Zheng Ren and had watched him grow, Zheng Ren’s statement directly denied his own skills.

Department Director Yan was very concerned about this.
