When there are too many people, there is a problem. The CT film is too small. When it is inserted into the film reader, the person in the front can see it clearly, but the people behind cannot see it at all.
Chen Xia counted the densely packed heads in the conference room. There were at least 100 doctors. It could be said that all the young doctors in the clinical departments were present, including many department heads or senior experts.
They are also quite interested in the CT machine that the hospital invested heavily in and is the second largest in the province.
Moreover, the role of CT machines is not limited to respiratory and cardiothoracic surgery. It is also of great significance to neurosurgery, general surgery, orthopedics, ENT, and even gynecology and gastroenterology.
Dean Gu was speechless when he looked at the small film reader on the podium. Not to mention the doctors at the back, even the doctors in the middle row couldn't see it.
"Xiao Xia, come here. Is there any way to enlarge this film so everyone can see it?"
The young doctors behind him also started to make noises: "Mr. Chen, hurry up and think of a solution. I can't see anything here even with a telescope."
Chen Xia raised his middle finger and said, "I see you're holding a telescope to watch the widow next door taking a bath, right?"
Hahahaha~~~~
The entire conference room erupted in laughter. Doctors, especially surgeons, loved telling dirty jokes. It not only relaxed them but also teased the nurses.
When a doctor is silent, sweating profusely, and his eyes are as big as light bulbs in the operating room, he is definitely doomed.
Either the operation is more difficult than imagined, or the diseased organ is no longer accessible, or your own level is not up to the task. In short, nothing good will happen.
"Okay, all of you wait for me, the immortal has his own ingenious plan."
After saying that, Chen Xia ran out of the meeting room, hid in the General Affairs Department, and then went into the Space Hospital.
The science and education department has everything, such as physical projectors and white screens, which are essential tools for regular lectures.
Chen Xia took out one. This physical projector is actually a video shooting mode. Place the prepared film or paper flat on it, and the content under the lens will be projected onto the white screen. It is very convenient and practical.
After Chen Xia returned to the conference room with the machine, he asked Wu Shaochen and Xie Liping to help cut out the CT films one by one.
He took out a CT film, put it on the projector, turned on the light switch, and the CT film immediately appeared on the white screen. It was very clear, which made everyone exclaim in surprise.
Even Dean Gu couldn't help but ask, "Where did you get this machine? Why haven't I seen it before? It's so useful."
"Uh, I think I bought it from Hong Kong. Now it's only available in Japan and the United States. You can't buy it in China, so forget it. Come on, let's get started."
Everyone's eyes were fixed on the white screen, and everyone took out their notebooks, ready to take careful notes.
"First, I'll show you a normal chest CT image. We can see that the patient's rib cage is symmetrical, the ribs run normally, the lung markings on both sides of the lungs run normally, there are no space-occupying lesions, and there are no inflammatory exudates.
The bronchovascular bundles in both lungs were not increased, thickened, or disordered. No abnormally enlarged lymph nodes were found in the mediastinum. The trachea and left and right mainstem bronchi appeared patent. There was no thickening or adhesion of the pleura on either side. The heart and great blood vessels were positioned normally, without abnormal dilatation or stenosis. The bone density of all thoracic bones was normal.
A normal chest image can reveal whether a patient has lung or pleural lesions, and can also indicate whether there are any mediastinal problems. Therefore, chest CT is the preferred imaging test for lung disease because it has a high resolution for density, and most diseases can be detected through chest CT.
As Chen Xia was talking, he began to draw a chest anatomy diagram on the blackboard.
"To view a chest CT scan, you must first understand the functions of the lung and mediastinal windows. To memorize anatomical names, you need to be as proficient in the anatomy and accurately locate the lesion, as the tissue structure and composition of the lesion are crucial for determining the disease's tissue type. Then, you can observe the divisions of the lung lobes layer by layer, from top to bottom."
Chen Xia then changed a CT scan, used a broom handle as a pointer, pointed at a certain spot on the screen, and said:
"Look, this is an anatomical diagram of the tracheal bifurcation. This is the right upper apical bronchus, this is the posterior branch of the right superior pulmonary vein, and this is the right main bronchus. Switching to the other slide, this is the posterior apical bronchus of the left upper lobe, and this is the left main bronchus."
Then Chen Xia took out different CT films and explained the basic CT anatomical structure to everyone.
For example, "right upper lobe bronchus level", "left main bronchus middle segment level", "left upper lobe proper segment and lingular segment bifurcation level", "right middle lobe bronchus opening level", "aortic arch supralevel", etc.
The entire conference room was very quiet, with only the rustling sound of pens moving across paper.
Chen Xia spoke relatively quickly because there was so much content. In his previous life, when he was teaching interns and residents in the department, he only had to take out the film and talk about the specific case based on it.
However, in today's explanation of film reading, although everyone has knowledge of anatomy, they have no foundation in CT film reading, so we have to start from the most basic things, which cannot be completed in one or two hours.
In the end, the lecture continued from 6pm to 12am without stopping.
In fact, Chen Xia had already collapsed from exhaustion. This was not a live streaming of selling goods on the Internet where he could talk non-stop and then declare to others that he had bought goods worth hundreds of millions in one night.
His mouth was completely dry. Chen Xia looked at the young doctors who were taking notes seriously in the audience and felt helpless. Why wasn't there anyone with good eyesight?
When he loosened his collar again and felt a little hot, Gu Lin handed him a thermos cup in time, smiled slightly, raised her hand and whispered "Come on".
Gu Lin, sitting at the back of the conference room, was already filled with pride at seeing her husband so wise and powerful. After all, they were husband and wife, and when she saw Chen Xia's constant little movements, she knew that this guy was tired, thirsty, and a little impatient.
So she quickly brewed some "ginseng and wolfberry tea", waited for the right moment and handed it to him, behaving like a "good wife and mother" in front of others.
Chen Xia looked at his watch and coughed a few times. "Everyone, we have to go to work tomorrow. Should we call it a day? I have to go back to Ke Town."
"No, no, Mr. Chen, could you please explain in more detail the differentiation between the inflammatory pseudotumor and lung cancer we saw yesterday? We didn't hear anything about it yesterday."
Chen Xia immediately sat on the podium. "Damn it! Kill me! I can't speak anymore."
