Chapter 1426: with translation of chapter title

Big Pig Trotter remained as stable as ever, neither overlooking tiny metastases that could not be detected nor providing the specific location of metastases.

"Zheng Lao Ban is really busy." Li Sister also wasn't unhappy, smiling and said: "A few days ago I prepared to come over, Director Yuan said you and the Royal Swedish Academy of Engineering people are researching basic physics formulas."

"I don't understand either; I just provide some clinical Shou Bing experience when making physics models." Zheng Ren said smiling.

"Can the test be repeated?" Li Lao standing aside asked.

"I can repeat the Shou Bing, but the work of establishing a system physics model is still under research; the involved formulas are relatively complex, I don't really understand." Zheng Ren said frankly.

Li Lao nodded.

"Let me introduce, this is Li Lao, an academician of the Engineering Academy, who has made outstanding contributions to protecting our country's rare and endangered wild animals." Vice President Yuan formally introduced: "Li Lao, this is our hospital's rising star, nominated for this year's Nobel Prize in Medicine."

"Hello, Li Lao." Zheng Ren made a Jiu Gong, respectfully greeting Li Lao.

"Really a rising star, are you thirty?" Li Lao asked smiling.

"Twenty-nine."

"What a good age." Li Lao felt somewhat moved, "Work hard, at your age you'll still be in your prime twenty years later; by then winning a Nobel Prize will bring glory to the country."

Zheng Ren smiled.

Teacher Li is perceptive; they never asked whether you could win this year, they jumped straight to twenty years later.

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

"No need to overtax your mind." Li Lao smiled slightly, saying: "I've asked some old fellows at the Chinese Academy of Sciences; liver cancer with metastasis but unable to locate the metastatic lesions is clinically common, yet there's no good solution."

"Dad, what are you saying?" Li Sister spoke petulantly, unhappy: "It's not metastasis at all; there's nothing, just a checkup."

Li Lao didn't directly rebuttal, just muttered to himself, "I'm not senile yet."

Zheng Ren didn't say anything; at this moment saying anything would be wrong.

Vice President Yuan said: "Li Lao, I still have things to attend to over there, so I won't accompany you. Zheng Ren, after the CT, if there are results come report to me."

"Yes." Zheng Ren replied immediately.

Li Lao waved his hand, saying: "Little Yuan, go ahead and be busy."

Time was still early; the patient hadn't arrived yet. The machine was already on, Director Chu and several deputy chiefs had come early. Liang Boshi followed last, seeing Zheng Lao Ban personally performing a CT on Li Lao, feeling somewhat moved.

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

"Mm-hmm, that's right." Zheng Ren just smiled.

"I understand anyway; no matter what you say, you're a scientific worker, don't hide things from me." Li Lao sat on the CT machine's bed, looking at Zheng Ren and said.

"Rest assured, it's really just a checkup. You also said earlier that the chance of finding a problem is small." Zheng Ren smiled: "Let's take a look to see if it works specifically; I'm not confident either."

Li Lao was dissatisfied with Zheng Ren's somewhat perfunctory attitude, but didn't say much, instead lying down on the examination bed.

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

A humming sound rose; the 912 CT machine is quite advanced, noise not large.

Scanning from head to toe, it took over twenty minutes; then Director Chu and others went to fetch Li Lao out.

Zheng Renze sat attentively at the console, focusing on making the images. When Li Lao came out, he simply stood up and said a few words, without seeing him off.

Because the system didn't give a diagnosis of visceral metastasis, Zheng Ren just went over the viscera once, seeing nothing, he left it. His main focus remained on the bones throughout the body, moving millimeter by millimeter downward from the skull.

Under normal circumstances, ECT is the main method for checking bone tissue for bone metastasis.

But this latent metastasis pattern of liver cancer cannot be detected by either ECT or PECT.

The lesion is too small, exceeding the technical level of current technology.

Zheng Ren merely wanted to try, to do his part for an elderly veteran.

"Zheng Lao Ban, can the CT show it?" Director Chu sent Li Lao away, returned to the CT Shi, sat beside Zheng Ren and asked.

"The chance of clearly seeing the lesion's location is small." Zheng Ren said: "But we can roughly know where there's a problem; later we can focus monitoring or think of some individual treatment methods."

Director Chu smiled, shook his head; he's been doing CT for thirty or forty years.

In 1972, Yingguo scientists successfully developed the first CT machine; in the 1980s of the last century, domestic imports of CT machines existed; at that time Director Chu was still a student and began exposure to early CT.

Up to now, Director Chu has also been in contact with machines that can perform CT scans on DNA.

But wanting to use such a fine machine to scan the whole body makes the possibility not large.

Regarding Li Lao's condition, Director Chu also had thoughts, but no definite idea.

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

Zheng Lao Ban is overthinking; this is Director Chu's idea. His level is high, which Director Chu acknowledges. But wanting to locate the metastatic lesions of liver cancer is nothing short of daydreaming.

But trying it never hurts.

Starting from the skull, Zheng Ren narrowed his eyes, almost frame by frame carefully examining the images.

Nearly an hour later, his hand suddenly moved.

Upon detecting an abnormal signal, Zheng Ren began to perform reconstruction.

Director Chu was almost falling asleep watching, but when Zheng Ren started moving, he perked up and looked closely.

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

In terms of normal bone density, the CT cross-section resembles a fence, with a relatively dense structure. As osteoporosis appears and worsens, the fence continually becomes sparser, and load-bearing capacity also gradually declines.

A slight disturbance could cause a compression fracture; for example, sitting down hard at home, or a jolt on a bus, could become a trauma trigger.

In the images on the console screen, there was no trace of any tumor appearing. Director Chu carefully looked twice, directly ruling out the possibility of bone metastasis.

Here the fence is relatively sparse, with some residual trabeculae-like images between the fence.

Although the morphology is uneven, those scattered existing trabeculae-like structures absolutely cannot be called metastases.

"Zheng Lao Ban? Do you suspect there's a problem here?" Director Chu asked.

"Mm." Zheng Ren nodded, continuing the reconstruction.

"No, the morphology here is fairly normal; I didn't see any abnormal images." Director Chu directly denied Zheng Ren's statement.

Although he gets along well with Zheng Ren and has watched him grow up, Zheng Ren's statement directly negated his own Technique.

Regarding this, Director Chu was very concerned.
