The curtains were tightened, the lights were turned off, and the entire ward became dark.

Chen Qi, this convenient B-ultrasound machine that is as convenient as a laptop computer, once again played a role.

I saw him holding the probe in his right hand, irradiating the patient's painful area back and forth, while manipulating the mouse on the left and right, taking screenshots and recording from time to time; his eyes never left the screen for a moment.

Including Dean Bagri, Director Momberto, Piet and Calema were all staring at the screen.

Doctors are all professionals, so it is easy to tell how advanced this "color ultrasound machine" is.

B-ultrasound machines were invented in the 1950s. By the 1980s, black-and-white B-ultrasounds were still the mainstream in the world, even if black-and-white machines have not been completely eliminated by 2022.

The color Doppler ultrasound detection technology, also known as the "color ultrasound machine", was just launched in the early 1980s, so it is now an advanced medical instrument in European and American countries.

As for the color ultrasound machine in Chen Qi's hands, it can no longer be described as advanced, it can only be said to be a product that transcends the times.

This high-definition LCD screen alone has never been seen before. As Chen Qi's probe moves, everyone can clearly see the internal organs.

B-ultrasound diagnosis displays the reflected echo signal on the instrument in the form of gray scale. The intensity of the gray scale reflects the echo interface reflection of the body's tissues and organs and attenuates the intensity of the ultrasound.

These two-dimensional plane images composed of gray-scale light points that are reflected back are common ultrasound images.

Therefore, it is very important to look at the echo performance of B-ultrasound, which is one of the basis for the doctor’s judgment.

For example, strong echo means that the echo is enhanced and accompanied by rear sound shadow. It is common in stones, the interface between air-containing lungs, and the surface of bones.

High echo is different from strong echo in that there is no sound shadow behind it and is seen in the capsules of organs such as the liver and spleen.

There is another type called isoechoic, which is a medium-level echo, found in the parenchyma of the liver, spleen, etc.

Typical hypoechoism is more common in subcutaneous fat.

The last type is anechoic. Typical anechoic is found in pure liquid substances such as bile, urine, thoracic and abdominal fluid, and transudate.

When Chen Qi's probe was fixed at the bile duct of the gallbladder, everyone clearly saw an abnormality.

Kalima was a little excited: "Look, the intrahepatic bile duct is slightly dilated."

There is secondary dilation of the bile duct, which is a strong indication of obstruction or space-occupying bile duct, and seems to further confirm the possibility of cholangiocarcinoma.

When doctors get excited, patients get nervous, especially Dr. Kalama, who can't spit out ivory from his mouth.

Vice President Mbeki asked nervously: "Dr. Chen, is this bile duct dilation good or bad?"

Chen Qi was a little hesitant and decided to tell the truth:

"Well, this doesn't seem to be a very friendly gesture. Don't worry, I have to continue checking..."

Chen Qi also wanted to comfort this poor little old African man, but who knew that Kalima screamed excitedly again at this time:

"Look, look here."

Kalima yelled and poked the screen with his finger, his whole aura changed.

On the B-ultrasound screen, I saw a nipple-like strong echo mass protruding into the dilated bile duct cavity.

Let's describe it this way. It was originally a smooth tube, but suddenly something protruded from the inside of the tube. It was clearly visible under Chen Qi's advanced color ultrasound.

Even if a doctor doesn’t need to answer, Vice President Mbeki, no matter how stupid he is, will know that something is wrong.

"Doctor, is it really cholangiocarcinoma?"

While he was talking, the little black old man's originally dark face had turned into a fair face, and he felt as if he was about to collapse.

Different from Kalima's excitement and conclusiveness, Chen Qi still has different opinions:

"Dr. Kalama, take a look around here. I just scanned around and found no enlargement or abnormal increase in peripheral lymph nodes. If this bulge is cholangiocarcinoma and it has developed to such an obvious level, it is impossible for the lymph nodes to be swollen or abnormally increased."

Normal."

Dr. Kalama is obviously not convinced:

"That's not necessarily true. Not all lymph nodes around cancer have problems, right? Maybe this is a sign that the cancer cells have not spread in a few cases?"

Chen Qi continued to retort:

"One more thing, B-ultrasound can only tell that there is such a thing in the bile duct, which may be the obstruction caused by this thing, but B-ultrasound cannot determine the boundary of the bulge and the internal blood flow, so now

It's too early to say it's cholangiocarcinoma."

Chen Qi’s point of view obviously did not convince Dr. Kalama. He continued to point to the screenshot on the screen and said:

"There is a bulge here. It's either a tumor or a calculus or inflammation. Doctor Chen, look at this echo. It doesn't match the possibility of a calculus or inflammation at all. So besides tumors, I can't think of any other possibility?"

Chen Qi continued to retort:

"You just said that there may be only a few cases. Does this inflammation look like cancer? Now, except for a bulge, the other symptoms do not support cancer."

Seeing the two doctors arguing, no one dared to breathe.

This is an obvious opinion analysis in front of the vice president of a country. Is this really treating the vice president as a cadre?

But Mbeki is happy in his heart. What he fears most is that all the doctors have unanimous opinions, just like the jury in the court unanimously agrees that he is guilty. Then there is really no hope at all.

The doctor has analyzed it, which means that the diagnosis of cholangiocarcinoma cannot be determined.

Then it might not be cancer, and is it possible to survive?

The patients are all psychologically fragile and want to hear good words, so the vice president rolled his eyes at Dr. Kalema, but when he looked at Chen Qi, his eyes were full of hope.

"Dr. Chen, do you think this doesn't look like cancer? That's good. Then what do you think of the next treatment?"

Chen Qi answered while packing up his portable color Doppler ultrasound machine:

"We will install the CT machine tonight, and we will do a CT first tomorrow morning. It is hard to say whether it is cancer. The argument I just had with Dr. Kalama was just to go through all the possibilities. We cannot arbitrarily say it is cancer.

, but this cancer cannot be ruled out."

Doctors always talk like this. They will never say everything. They are so vague that what they say is the same as what they haven’t said.

Mbeki was disappointed after hearing this, and lay back on the bed to think about his thoughts.

Mrs. Mbeki was anxious: "Dr. Chen, since we can't be sure whether it is cancer, we won't do the examination. We can just do an operation to remove it."

Chen Ji said a little embarrassed:

"Madam, it's okay if it's not cancer, but if it's confirmed to be cholangiocarcinoma, then the scope of this operation will require the removal of four nearby organs, and the operation may worsen death.

Moreover, the operation time is more than 10 hours, and many people may not be able to get off the operating table. It is not an exaggeration to say that it is the most difficult surgical operation, especially given the medical conditions in Sierra Leone, it is even less optimistic."

Once she heard that it would be fine without surgery, she might die on the spot if she had surgery. Mrs. Mbeki was so frightened that she covered her mouth and did not dare to ask any more questions.

Coming out of the ward, Dean Bagri was a little anxious:

"Dr. Chen, even if you bring a CT scan, our hospital's computer room currently does not have the conditions to install a CT scan. We need to do a CT scan tomorrow. What should we do?"

Chen Qi is obviously confident:

"It's urgent, right? If there is no CT machine room, we will temporarily use an

of.

Besides, look at Mr. Mbeki, he is eager to start a CT scan tonight. Before, it was easy to do without a CT scan. Now that we have this machine, it will take a few days. Believe it or not, I can easily remove you from the position of president.

Get lost?"

Bagri realized the seriousness of the matter as soon as he heard it.

No matter how big or small the leader’s views are, especially in a country with imperfect laws, the leader can not only decide your future, but even your life or death.

"Okay, okay, I listen to Dr. Chen. I will immediately organize all the plumbers, electricians and logistics staff in the hospital to ensure that they work all night and overtime tonight."

Chen Qi patted Dean Bagri on the shoulder:

"That's right. This is the attitude you need. Just wait. I'll transport the CT over in the evening. You have to prepare the forklift and loading and unloading personnel. The machine weighs several tons and is very heavy."<

/p>

Nonsense, this is about 250,000 US dollars in extra money, how can you not seize it in time?

It sells for 50,000 US dollars in China, but it sells to big dogs in Africa for 250,000 US dollars. How can such a good business be done? The cost is almost zero.

With so much money, it would be great to buy U.S. stocks, which could be worth hundreds of millions in the future.

That night, Chen Qi drove alone to the beach, and then brought out a second-hand truck from the space, with a CT scanner installed in the truck and ran to the Freetown National Hospital.

Some people may think, where did your CT come from? What transportation method was used? Is there a customs report? They will definitely check yours, and they won’t be able to tell at that time.

In fact, this is all too much to worry about.

Let alone a country without much legal order and normal trade, even in a certain country in the 1980s, gray businesses along the coast should not be too prosperous.

The car you just "landed" can still get a license plate. Have people asked you where it came from?

Unless you have offended someone and someone wants to punish you, they will investigate your origin, otherwise no one will be full enough to do such a thing that is not good for others or self-interest.

In particular, Chen Qi’s CT machine is used by Mbeki and other senior officials. Who dares to check it?

Chen Qi hummed a little tune and drove a big truck to transport the machine to the National Hospital in Freetown. As expected, the lights were bright and a lot of people were waiting.

The most excited person is Dean Bagri. Which dean or doctor doesn’t want to have this kind of advanced medical equipment, which can improve the overall clinical level by several levels.

Many diseases that could not be treated or were not dared to be treated before can now be treated with the help of CT.
