Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 1599 [1599] What to do to check the heart

   The young doctor that Dr. Xu examined is exactly this point.

   "Heart." Dr. Zhao, who was preparing for the operation, replied, "The application report issued by the clinician believes that there may be something wrong with the patient's heart and needs to be investigated."

  Doctor Xu seemed dissatisfied with his rough answer, thinking that perhaps the clinician's summary of the patient's condition was too simplistic for the young doctor to judge carefully, so he grabbed the application report on the table and read it again. After reading for a while, I thought that I was standing next to the patient's family, so I simply asked Xie Xie, "Do you know his situation?"

   Knowing what the teacher wanted to ask, Xie Wanying replied: "Using CT for heart examination itself is flawed and difficult."

   The answer of the other party is the Gate of Life. Dr. Xu turned back and winked at her, and said with a smile, "How many years have you studied with Teacher Qin?"

  Xie Wanying was ashamed, she seemed to have only had one conversation with Teacher Qin, and this time it was definitely a light for Teacher Qin.

   Seeing that there was something strange in her momentary silence, Dr. Xu asked curiously, "Aren't you a student of imaging science?"

no. Xie Wanying shook her head honestly.

   Dr. Zhao, who was sitting in front, turned his head and thought that Xie Wanying's answer just now was completely like an imaging student, what happened.

   "I am a surgical student." Xie Wanying replied.

   "Does the surgical student know what the CT scan of the heart can detect?" Dr. Xu asked her again.

"CT examination of the heart is the same as examination of other tissues and organs. It can be done according to the basic principles. The problem is that in order to find out the lesions of the heart, CT has to face a difficult point. The heart is an autonomous mechanism in the human body. The rhythm is an organ that has been doing systolic and diastolic movements. It means that it is doing movement all the time. For imaging examinations, it is best for the target object to stay still. Therefore, we require patients to keep their bodies still during the examination, to be quiet, and to be still. Adjust your breathing according to the doctor's request to expand and shrink the lungs, etc. But the heart's activity, the patient and the doctor can't control how it moves." Xie Wanying said.

   Dr. Zhao pursed his lips: Is she really not an imaging student?

   "Mmmm." Listening to the depth of her words, Dr. Xu encouraged her to continue to express her opinions, "You can talk more."

Xie Wanying continued to express her opinion: "CT and X-ray can be compared to a camera. If you want to capture the subtle changes of the heart that are dynamic all the time, the shutter speed of this camera needs to be as fast as possible. Therefore, in the In terms of cardiovascular, CT has no advantage. What has the advantage is the imaging machine. The imaging machine in the interventional operating room can shoot 30 frames per second, with a time resolution of 33 milliseconds, and the obtained cardiovascular images are sharp and clear. Single source The shutter speed of ct is less than a quarter of that of an angiography machine. Compared with the former, the latter must be slower to capture dynamic images, and it is destined to have a greater chance of missing grasping problems. Therefore, there is a clinical saying that coronary angiography is the only way to diagnose coronary artery disease. The gold standard for heart disease."

   "She remembers the numbers very well." Dr. Zhao admired while grabbing the back of the chair.

  Doctor Xu snapped and photographed his student's head: You praise people and don't think about yourself?

   Dr. Zhao touched his head, which was patted by the teacher, and laughed. He didn't care. Medicine needs to learn from each other. There must be my teacher in a three-way trip.

   "Single-source CT is slower, and dual-source CT is much better." Dr. Xu concluded and fully agreed with what Xie Wanying just said.
