Chen Xia was a little confused when she received this call for help:

"I said to Director Luo, you senior directors read a movie, and you still want me, a young doctor, to take a look?"

Luo Wei was very embarrassed. She was a business backbone in her 40s, but she wanted to ask for advice from a "barefoot doctor" with a secondary technical education, but now there is no way to do it.

"Secretary Chen, don't be humble. You suggested that you buy CT at the time. I don't believe you don't know how to read a movie. Come here quickly, Director Feng is still waiting."

"Okay, then I'll take a look. I'll give you a subsidy at that time."

"Get out, hurry up."

When Chen Xia appeared in the CT room, there was already a group of people inside. There was a CT film on the reader. Everyone was huddled together head-to-head, listening to Luo Wei and Shi Zhixian's own reasons.

Seeing that no one paid attention to him, Chen Xia squeezed away a few young doctors and went in by himself. When he saw this movie, he blurted out:

"Oh, this person is unlucky enough. This is peripheral lung cancer."

Shi Zhixian was dissatisfied when he heard this and said without looking back:

"How could this be lung cancer? Inflammatory pseudo-tumors are also mainly burrs. We cannot just see burrs and say that it is lung cancer. Look, the edges here are quite smooth."

When everyone saw Chen Xia coming, they immediately spread out. They almost felt hypoxia when they squeezed together just now.

Chen Xia patted the middle-aged doctor on the shoulder,

"Even if you look at the burrs, you have to distinguish between long and short burrs. Inflammatory pseudo-tumors are indeed mainly long burrs. Lung cancer burrs show different lengths, and short burrs are very diagnostic."

After saying that, he clicked on the burrs on the upper side of the film: "You see, this is a typical short burr. If it is a long burr, it is usually so long."

Oh~~~

Everyone agreed with a slight understanding, obviously this statement did not convince everyone.

Bai Yunjun took the opportunity to say, "Chen Laoshi, then tell us the reason why you insist on lung cancer in one bite?"

Everyone nodded together, and even Luo Wei and Shi Zhixian pricked their ears. Whoever is right or wrong in this first difficult and complicated disease will directly affect the big question of who is authoritative in the future CT room.

Not everyone who comes out of the hospital is as brainless as Gu Lin and Chen Xia. They have high IQ and EQ, and most of them are making trouble in their stomachs and care a lot.

Chen Xia lit the nodule again and said, "Look, does this nodule not look like a round shape? Instead, it looks like there are three leaves?"

Everyone looked carefully and even Feng Runguang pushed his glasses.

"From an imaging perspective, this is called lobular sign, which is the most common sign of surrounding small lung cancer. Everyone knows that malignant lung nodules are composed of many cancer cells, and after absorbing nutrients from the human body, they will continue to reproduce and increase.

However, the reproduction speed of many cancer cells is inconsistent, both fast and slow. The cancer cells that reproduce quickly will protrude faster, or are blocked by the surrounding connective tissue, causing multiple bulges on the surface of the tumor. The CT section is like a leaf."

Feng Runguang and Luo Wei are veteran doctors after all, and they understood the truth as soon as they heard it and nodded repeatedly.

Even Shi Zhi was a little dejected when he heard this. It seemed that he would still be the second son of a thousand years.

At this time, another young doctor asked next to him: "Chen Laoshi, you said that the lobe sign is a manifestation of lung cancer. Are there any other typical signs of lung cancer?"

"Yes, for example, the burr just now is called burr sign in the film. This is because there are multiple small burrs around the tumor, and the malignancy is usually higher than the nodules with smooth edges.

What is a burr? It is caused by tumor cells blocking pulmonary blood vessels or lymphatic vessels, causing thickening of the lung lobular septal and local fibrosis, or the collapse of a small number of alveolars near the pulmonary atelectasis. Anyone who sees burr signs, 90% are malignant tumors."

Oh~~~~

Several young doctors are already taking notes.

"There is another type called spinous process, because some lung cancers, by chance, will produce some special forces with strong combat power, which will reproduce rapidly and can penetrate the surrounding lung tissue like spikes.

This form of cancer cells is more fierce and grows faster. Most patients have been alive in just a few months. According to the current treatment methods, there is no way to do it."

Chen Xia was still afraid that everyone would not understand, so she drew it on paper. After all, no matter how well the description was, it was easier to remember without the eyes to see it directly.

When you see a corner of the nodule on the white paper, it is full of hair. I hope you won’t get this unlucky disease in the future.

Then Chen Xia drew another sign of lung cancer.

"Look at it again, this bronchus is a hollow pipe, which penetrates deeper into the lungs on both sides like branches and becomes thinner and thinner, and finally reaches the alveolar cavity, which is the pipe where air enters and exits the alveolar cavity.

At this time, the cancer cells that occur in the bronchial mucosa will gradually rise, increase, and block the bronchial. Malignant tumors next to the bronchial can also invade the tracheal wall and grow into the cavity, causing bronchial truncation, and this bronchial loses the function of lung ventilation, which is called bronchial truncation sign."

After such an explanation and summary, everyone immediately grasped these four special signs, especially the young doctors who looked excited and admiring, and they wanted to accept their heads and worship.

Chen Xia was still a little proud, and continued to teach:

"Single-shot malignant nodules, especially peripheral lung cancer, have many typical characteristics on CT films. If you are familiar with these characteristics, you can see through the disguise of malignant lung nodules. Today I will share with you four common malignant characteristics. It is very simple, and you can ensure that you can learn it by watching it once."

After saying that, he wiped his hair with one hand: "Don't envy brother, I'm just a legend."

Feng Runguang scolded angrily: "You little brat, I don't know where I learned these CT knowledge, so I understand a little bit of the superficiality. What a pride."

Luo Wei studied for half a year, but instead admired Chen Xia's casual knowledge:

"No, this is not the superficial, it has a solid theoretical and practical foundation. Chen Xia, where did you learn this from? The doctors from the First Hospital of the Provincial Hospital have never mentioned it."

"Haha, this, I'm quite humble and easy to learn. When I went to Xiangjiang this time, the leaders went to buy CT. With the help of my grandfather, I learned about reading knowledge about films with the doctors in Xiangjiang for several days."

Oh,~~~~~

The explanation makes sense. He has a good grandfather in Xiangjiang, and the doctor specifically prescribes small stomps for him alone. I guess he can learn a lot.

But no one would have thought that Chen Xia was busy doing things like a second-hand dealer all day long, so he didn’t have time to learn CT?

"Ahem, but your thoughts have entered a misunderstanding, clinical diagnosis attaches too much importance to the role of CT."
