Chapter 1381 Search Frame by Frame

The big pig's trotter is still as stable as ever, neither ignoring the small and undetectable metastases nor giving the specific location of the metastases.

"Boss Zheng is really busy." Sister Li was not unhappy, and said with a smile: "I was going to come a few days ago. President Yuan said that you and the people from the Royal Swedish Academy of Engineering are studying basic physics formulas."

"I don't understand either, just provide some clinical surgery experience when making physical models." Zheng Ren said with a smile.

"Can you repeat the test?" asked Old Man Li, who was standing on the side.

"I can repeat the operation, and the establishment of a physical model of the system is still under study. The formulas involved are relatively complicated, and I don't understand it very well." Zheng Ren frankly.

Old 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: "Lao Li, this is us. A rising star in the hospital, recommended by this year's Nobel Prize in Medicine."

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

"It's really a rising star, there are thirty?" Li Lao asked with a smile.

"Twenty-nine."

"It's really a good age." Old Li sighed with emotion, "Work hard, at your age, you will still be at the peak of spring and autumn in twenty years, and then you will win a Nobel Prize and win glory for the country."

Zheng Ren smiled.

Mr. Li understands people. They didn't ask if they could get it this year. It would be 20 years later.

"Mr. Li, let's go, let's do CT." Zheng Ren said.

"Don't worry too much." Li Lao smiled slightly and said: "I have asked some old guys from the Chinese Academy of Sciences, liver cancer complicated by metastasis, but no metastatic lesions can be found. This is a common clinical thing, but there is no good way. "

"Dad, what are you talking about." Sister Li said unhappily, "It's not a transfer at all, there's nothing wrong, it's just a medical examination."

Li Lao did not directly refute, but muttered to himself, "I'm not confused."

Zheng Ren didn't say anything, what he said at this time was wrong.

Vice President Yuan said: "Mr. Li, I still have something to do on my side, so I won't accompany me. Zheng Ren, after the CT is done, report to me with the results."

"Yes." Zheng Ren replied immediately.

Old Li waved his hand and said, "Xiao Yuan, go ahead."

It was still early and the patient did not come up. The machine was already turned on, and Director Chu and several deputy directors came early. Dr. Liang followed at the end, and he felt a little emotional when he saw that Boss Zheng performed a CT scan for Mr. Li himself.

Zheng Ren wanted to help Li Lao to lie down, but as soon as he stretched out his hand, Li Lao pushed him away, "No, I'm not old yet."

"En, that is." Zheng Ren just smiled.

"I understand that, after all, you are considered a technology worker. Don't hide anything 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 say it too, it's not likely to find the problem." Zheng Ren smiled: "Check it out, I'm not sure if it will work or not."

Mr. Li was very dissatisfied with Zheng Ren's slightly perfunctory attitude, but he didn't say much, but lay down on the clinic bed.

Director Chu pressed the button, the bed moved in, and several people walked out.

The hum sounded, the 912's CT machine was very advanced, and the noise was not too loud.

It took more than 20 minutes to scan it from head to toe before Director Chu and others went to pick up Mr. Li.

Zheng Ren sat upright in front of the console and worked on the film attentively. When Mr. Li came out, he just stood up and said a word, but did not send him off.

Because the system did not give a diagnosis of visceral metastasis, Zheng Ren just passed the viscera once, and it was fine when he saw that it was all right. The main attention is still on the bones of the whole body, starting from the skull bone and moving down millimeter by millimeter.

Under normal circumstances, ECT is the main way to check the bone for bone metastases.

However, this latent metastasis of liver cancer cannot be detected by either ECT or PECT.

The lesions are too small to exceed the technical level of existing technology.

Zheng Ren just wanted to try and do his best to an elderly Dexun old man.

"Boss Zheng, can you tell from the CT?" Director Chu sent Mr. Li away, returned to the CT room, and sat next to Zheng Ren.

"It's unlikely that you can clearly see the location of the lesion." Zheng Ren said: "But if you can roughly know what is wrong, you can focus on monitoring in the future, or think of some other way to treat it."

Director Chu smiled and shook his head. He has been doing CT for thirty or forty years.

In 1972, British scientists successfully researched 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.

Until now, Director Chu, a machine that can perform CT scans of DNA, has been in contact.

Just wanting to use such a delicate machine to examine the whole body is not possible.

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

With existing technology, there is still a blind spot here. To confirm the diagnosis, we can only wait for technological progress.

Boss Zheng thinks a lot, this is Director Chu's idea. His level is high, Director Chu admitted. But trying to find the location of the metastatic lesions of liver cancer is tantamount to fooling around.

But give it a try, it never hurts.

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

Nearly an hour later, his hand suddenly moved.

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

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

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

In terms of normal bone density, the cross-section of CT is like a fence, and the structure is relatively dense. With the appearance and aggravation of osteoporosis, the fence will continue to become loose, and the load-bearing will gradually decrease.

If there is any bellowing, a compression fracture may occur. For example, sitting in a fart squat at home, such as a bump on the bus, may become an incentive for trauma.

In the images on the console screen, there is no trace of any tumor. Director Chu looked at it twice and directly ruled out the possibility of bone metastases.

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

It looks uneven in shape, but those trabecular bone and other things that exist everywhere can never be said to be metastatic tumors.

"Boss Zheng? Do you suspect there is a problem here?" Director Chu asked.

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

"No, the shape here is relatively normal, and no abnormal images have been seen." Director Chu directly denied Zheng Ren's statement.

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

Director Chu was very concerned about this.
