¡¾1599¡¿What kind of examination should be done on the heart?

    This is exactly what Dr. Xu is looking for as a young doctor.

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

    Dr. Xu seemed not very satisfied with his rough answer. Thinking that maybe the summary of the patient's condition written by the clinician was too simple, which prevented the young doctor from making a careful judgment, he grabbed the application report on the table and read it again.  After reading for a while, I thought that the family members of the patient were standing next to me, so I simply asked my classmate Xie: "Do you know anything about his condition?"

    Knowing what the teacher wanted to ask about, Xie Wanying replied: "Using CT to do heart examination itself has flaws and is more difficult."

    The other party¡¯s answer is Mingmen.  Dr. Xu turned around, winked at her, and said with a smile, "How many years have you been studying with your teacher Qin?"

    Xie Wanying was ashamed. She seemed to have only had one conversation with Teacher Qin. This time she was definitely trying to take advantage of Teacher Qin.

    Seeing something fishy 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 around and thought that Xie Wanying's answer just now sounded like that of an imaging student. What was going on?

    "I'm a surgeon." Xie Wanying answered.

    "Do surgeons understand what CT can detect when examining the heart?" Dr. Xu asked her again.

    "CT examination of the heart can be done just like examination of other tissues and organs according to the basic principles. The problem is that if you want to find out the signs of heart disease, CT must face a difficulty. The heart is a part of the human body.  An organ that has an autonomous rhythm and is constantly contracting and relaxing. In other words, it is in motion all the time. For imaging examinations, it is best if the target object remains motionless, so we require the patient to remain still and quiet during the examination.  You need to adjust your breathing to allow the lungs to expand and contract according to the doctor's instructions. But the patient and the doctor cannot control how the heart moves," said Xie Wanying.

    Dr. Zhao pursed her lips: Isn¡¯t she really an imaging student?

    "Yeah." Listening to the depth of her words, Dr. Xu encouraged her to continue expressing her opinion, "You can tell me more."

    Xie Wanying continued to express her opinion: "CT and X-ray can be compared to cameras. If you want to capture the subtle changes in the dynamic heart all the time, the shutter speed of this camera needs to be as fast as possible. So, in  In terms of cardiovascular blood vessels, CT has no advantages. What has the advantage is the imaging machine. The imaging machine in the interventional operating room can capture 30 frames per second with a time resolution of 33 milliseconds. The resulting cardiac blood vessel images are sharp and clear. Single source  The shutter speed of a CT scan is less than a quarter of that of an angiography machine. The latter is definitely slower in capturing dynamic images than the former, and is destined to have a greater chance of missing images. Therefore, there is a saying in clinical practice that coronary angiography is the diagnostic tool for coronary angiography.  The gold standard for heart disease.¡±

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

    Doctor Xu snapped a picture of his student¡¯s head: When you praise others, don¡¯t you think about yourself?

    Dr. Zhao touched his head that was slapped by the teacher and laughed. He didn't care. In medicine, we need to learn from each other. If we are three people, there must be one teacher for each other.

    "Single-source CT is slower, but dual-source CT will be much better." Dr. Xu concluded, fully agreeing with what Xie Wanying just said.  (Remember the website address: www.hlnovel.com
