Since 1981 Health School

  The curtains were pulled tight, and the lights were turned off, making the entire ward dark.

  Chen Qi, this convenient B-ultrasound machine similar to a laptop, once again played a role.

  I saw him holding the probe in his right hand, irradiating the painful part of the patient non-stop, and manipulating the mouse left and right, taking screenshots and recording from time to time; neither eye left the screen for a moment.

  Including Dean Bagri, Director Mombetto, and Piet and Callema are all staring at the screen.

  Doctors are professionals, so it is easy to tell the advanced level of this "color ultrasound machine".

  B-ultrasound was invented in the 1950s. By the 1980s, the world’s mainstream was still dominated by black-and-white B-ultrasound, even though black-and-white machines have not been completely eliminated by 2022.

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

  As for the color Doppler ultrasound machine in Chen Qi's hand, it can no longer be described as advanced, it can only be said to be a product of a cross-generational era.

   You have never seen this high-definition LCD screen. With the movement of Chen Qi's probe, you can see the internal organs very clearly.

  B-ultrasound diagnosis is to display the reflected echo signal on the instrument in the form of gray scale. The strength of gray scale reflects the strength of echo interface reflection and attenuation of ultrasound in tissues and organs of the body.

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

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

  For example, strong echo refers to enhanced echo, accompanied by rear acoustic shadow, which is common in stones, the interface of air-containing lungs, and the surface of bones.

  Different from strong echo, hyperechoic is not accompanied by acoustic shadow behind, and is seen in the capsule of liver and spleen.

   There is also a kind of echo called iso-echo, that is, a medium-level echo, which is found in the parenchyma of the liver and spleen.

  The typical hypoechoic is more common in subcutaneous fat.

  The last type is anechoic, and typical anechoic is seen in pure liquid substances such as bile, urine, pleural and ascites, and transudates.

  When Chen Qi's probe was fixed at the position of the gallbladder bile duct, everyone could clearly see the abnormality.

  Calema was a little excited: "Look, this intrahepatic bile duct is slightly dilated."

  The bile duct has secondary dilation, which strongly suggests that the biliary tract is obstructed or space-occupied, and it seems to further confirm the possibility of cholangiocarcinoma.

  When the doctor is excited, the patient is nervous, especially Dr. Kalema, who can't spit out ivory from his dog's mouth.

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

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

   "Uh, this doesn't seem to be too friendly, don't worry, keep checking..."

  Chen Qi still wanted to comfort this poor little African old man, who knew that Kalema exclaimed excitedly again at this time:

   "Look, look here."

  Calema yelled while poking the screen with his finger, his whole demeanor changed.

  On the B-ultrasound screen, a papillary hyperechoic mass protruded into the dilated bile duct lumen.

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

  Even if the doctor didn't need to answer, Mbeki Vice President L would know something was wrong no matter how stupid he was.

   "Doctor, is it really, really bile duct cancer?"

   While talking, the little black old man's originally a little black face has turned into a little white face, and he feels like he is about to fall down.

  Different from Kalema's excitement, and with certainty, Chen Qi still has a different opinion:

"Dr. Calema, look around here. I just scanned around, and I didn't find any swelling or abnormal increase in the surrounding lymph nodes. If this bulge is bile duct cancer, it's impossible for the lymph nodes to develop so obviously. normal."

  Dr. Kalema is obviously not convinced:

   "That's not necessarily the case. Not all cancers have problems with the lymph nodes around them, right? Maybe this is the manifestation of a few cases of cancer cells that have not spread?"

  Chen Qi continued to retort:

"There is another one. The B-ultrasound can only know that there is such a thing in the bile duct, which may be the obstruction caused by this thing, but the 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. Kalema, he continued pointing to the screenshot on the screen and said:

   "There is a bulge in this place, which is either a tumor or a stone or inflammation. Doctor Chen, the echo does not match the possibility of stone or inflammation at all. So I can't think of any other possibility besides a tumor?"

  Chen Qi continued to retort:

   "As you said just now, there may be only a few cases. Does this inflammation look like cancer? Now except for a bump, other symptoms do not support cancer."

  Seeing the two doctors arguing, everyone dared not breathe.

  This is an obvious opinion analysis in front of the vice president of a country. Does this really make the vice president L a cadre?

  But Mbeki is happy in his heart. What he fears most is that all the doctors agree, just like the jury in the court unanimously found guilty, and there is really no hope at all.

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

   Then it may not be cancer, can it survive?

  Patients are psychologically fragile, and they all want to hear good things, so the vice president gave Dr. Kalema a white look, but when he looked at Chen Qi, his eyes were full of hope.

   "Doctor Chen, do you think this is not like cancer? That's good, then how do you treat it next?"

  Chen Qi replied while packing up his portable color ultrasound machine:

"Let's install the CT machine tonight. Let's do the CT first tomorrow morning. It's hard to say whether it's cancer. I just had an argument with Dr. Calema. I just went through all the possibilities. I can't arbitrarily say it's cancer." , but the cancer cannot be ruled out."

  Doctors always talk like this, and they will never talk full of words.

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

  Mrs. Mbeki was in a hurry: "Dr. Chen, since we are not sure whether it is cancer or not, we don't want to check it. We just have an operation to remove it."

  Chen Ji said a bit embarrassed:

   "Madam, it's okay if it's not cancer, but if it's confirmed to be bile duct cancer, then the scope of this operation needs to remove four nearby organs, and the operation may actually exacerbate death.

  And the operation time is more than 10 hours. 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 operation in surgery, especially the medical conditions in Sierra Lean. It is even more unoptimistic. "

   It would be fine to hear that there is no operation, but if the operation is performed, she may die on the spot. Mrs. Mbeki was so scared that she covered her mouth and dared not ask any more questions.

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

   "Dr. Chen, even if you bring the CT, but the computer room of our hospital is not able to install a CT for the time being. We will do a CT tomorrow. What should we do?"

   Chen Qi obviously has a plan in mind:

"It's important to have a priority. There is no CT machine room, so we will temporarily use an X-ray machine room instead. Although it is not safe, we will only do one CT, so that all unrelated personnel will stay far away, and there will be no major problems. of.

Besides, look at Mr. Mbeki's appearance, he can't wait to start doing CT tonight. It's okay to say that there was no CT before, but now it will take a few days to delay with this machine. **** off? "

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

  Thousands of things are great, no matter how big the leader's opinion is, especially in such a country with imperfect laws, the leader can not only determine your future, but even your life and death.

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

  Chen Qi patted Dean Bagley on the shoulder:

   "That's right, this is the attitude you need. Just wait. I'll bring the CT over in the evening. Prepare forklifts and loading and unloading personnel. The machine weighs several tons, and it's dead heavy."

   Nonsense, this is related to 250,000 dollars in extra money, how can we not hurry up in time?

  It sells for 50,000 US dollars in China, and 250,000 US dollars to a big dog in Africa. Where is such an easy business? The cost is almost zero.

  With so much money, it’s a lot of fun to buy U.S. stocks. In the future, they will be worth hundreds of millions, okay?

  That night, Chen Qi drove to the seaside by himself, and then got out of the space with a second-hand truck with CT loaded on it to go to Freetown National Hospital.

  Some people may think, how did you get this CT? By what means of transport? Is there any customs declaration? People will definitely check you, and they won't be able to tell by then.

  In fact, this kind of worry is too much.

  Don’t mention this kind of country without much legal order and normal trade, even if it was a certain country in the 1980s, the gray business along the coast should not be too prosperous.

  The car you "go ashore" directly can still have a license plate. Did people ask you where it came from?

  Unless you offend someone and someone wants to punish you, you will search your source. Otherwise, no one will be full enough to do such things that are not good for others or themselves.

   In particular, Chen Qi's CT machine was used by Mbeki and other senior officials. Who would dare to check it?

  Chen Qi hummed a ditty and drove a large truck to transport the machine to Freetown National Hospital. As expected, there were bright lights and a lot of people were waiting.

   Dean Bagli is the one who is most excited. Which dean or doctor would not 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 dared to be treated before can now be treated with the assistance of CT.

  This time, if he hadn’t taken advantage of L, the vice president of a wealthy family, otherwise, he didn’t know when this CT dream would come true, so Bagri looked at Chen Qi, and the more he looked at it, the happier he became.

  Chen Qi is not an equipment worker, and it’s done after sending the machine and installation drawings. How to install it is his business.

  Without regard to safety and radiation, the installation is also simple. It just needs to fix the machine and arrange the cables. The instructions of the Mayo Clinic are very detailed.

  Mbeki's secretary was waiting at the scene. When she saw that Chen Qi had delivered the CT machine as scheduled, she quickly handed over a box.

   "Dr. Chen, this is 250,000 US dollars, which is the payment for the purchase of CT. You need to sign a few names here."

   Necessary procedures still have to be followed, Chen Qi didn't care, picked up a pen and directly signed his English name on the contract

   "Jack Chen".

  Carrying the heavy box of money in his hand, Chen Qi laughed so hard that his molars were almost exposed:

   "Hehehe, good, good, your country's work efficiency is really high, and it really is a good ZF with a clean and honest government."

   I vomited in my heart.

  When Secretary Mbeki heard that foreigners praised his country, he was of course very honored, and the smile on his face became even brighter.

"Everywhere, this is what we should do. By the way, Dr. Chen, Mr. Vice President L has one more thing for me to pass on to you. I hope you can bring more benefits to everyone in the next diagnosis and treatment process. information."

   After speaking, the secretary took out a wooden box from the handbag.

  Chen Qi opened it, and smiled so much that not to mention the back molars, even the tonsils were almost exposed, because the box contained two rough diamonds the size of pigeon eggs.

   It has been a year since I came to Africa, and Chen Qi can be regarded as a knowledgeable person. It is absolutely no problem to cut such a large rough diamond, and each one can be 2 to 30 carats.

  Decades later, it will be sold to coal bosses upstarts. It is a small case to sell for hundreds or even tens of millions.

  It will be more than enough to sell these two rough diamonds and replace them with a 3.0T MRI machine.

   I want to thank that China’s economy has not yet developed at this time, and the price of diamond hype around the world has not reached its peak. It is estimated that in a few decades, killing black people will not give away such a large rough diamond.

  Take other people's money and do things for them. This habit has always been Dean Chen's greatest strength.

   "Don't worry, Mr. Secretary, please tell Vice President L, I will do my best to serve him, for the friendship between the two countries!"

   At this time, the secretary looked around and asked in a low voice:

   "Doctor Chen, do you think Mbeki's condition is optimistic or not?"

  Chen Qi was a little surprised, thinking that this little secretary is also very active in thinking, is it possible that the master is unreliable and ready to leave a way out?

   "The possibility of cancer still exists. It's hard to say now. According to my judgment over the years, it is at most half and half. Tomorrow's CT can be more clear, but it is not a diagnosis. A pathological section or other examinations are required for a diagnosis."

  The secretary nodded thoughtfully.

  Early the next morning, the original X-ray machine room was surrounded by doctors. Everyone wanted to come and see what the first CT machine in Sierra Lean was like and how it worked.

  Dean Bagley has been chasing people away, "Go away, go away, and those who don't want to eat the rays, get out of the way, what's so good about this thing."

  Vice President L of Mbeki, accompanied by a large group of people, came here in a mighty way. When he saw Chen Qi, he tightly held the hand of the Huaguo doctor:

   "Dr. Chen, only you can operate CT here, please~~~~"
