This is exactly the point that Dr. Xu took the young doctor exam.

"Heart." Dr. Zhao, who was preparing for the operation, replied, "The clinician called the application report and believed that the patient's heart might have something to do and need to be investigated."

Dr. Xu seemed not very satisfied with his rough answer. Thinking that perhaps the patient's summary written by the clinician was too simple, the young doctor could not make a careful judgment, so he grabbed the application report on the counter and read it again. After reading for a while, he thought that the patient's family was standing beside him, so he simply asked a few questions from Xie: "Do you know his situation?"

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

The other party’s answer was Mingmen. Doctor Xu turned around and blinked at her, and smiled and said, “How many years have you learned from Teacher Qin?”

Xie Wanying was ashamed. She seemed to have only talked with Teacher Qin. This time she was definitely taking advantage of Teacher Qin's favor.

Seeing that her momentary silence was strange, Dr. Xu asked curiously: "Aren't you a student of the subject of imaging?"

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 looked like a imaging student. What's going on?

"I am a surgeon." Xie Wanying replied.

"Can the surgeon understand what can be detected by CT's heart test?" Dr. Xu asked her again.

"CT is the same as examining other tissues and organs. According to the basic principle, it can be done. The problem is that to find out the signs of the heart, CT must face a difficult point. The heart is an organ in the human body that has an autonomous rhythm that has been performing contraction and diastolic movements. It is equivalent to saying that it is always doing exercise. When doing imaging examinations, it is best to keep the target object still. Therefore, we require patients to remain motionless when doing examinations, and to adjust their breathing according to the doctor's requirements to make the lungs expand and shrink. However, patients and doctors cannot control how the heart move." Xie Wanying said.

Dr. Zhao shrank his lips: Isn’t she really an imaging student?

"Yeah." Listening to her words, Dr. Xu encouraged her to continue expressing her opinions, "You talk about it."

Xie Wanying continued to express her opinion: "CT can be compared to X-rays as a camera. If you want to grasp the dynamic heart that is constantly changing, the shutter speed of this camera presses needs to be fast and as fast as possible. Therefore, in terms of cardiac blood vessels, CT has no advantage. The advantage is the graphic machine. The graphic machine in the interventional operating room can take 30 frames per second, with a time resolution of 33 milliseconds, and the resulting cardiac blood vessel image is sharp and clear. The shutter speed of a single source CT is less than one-quarter of that of the graphic machine. The latter is definitely slower than the former to capture dynamic images, and the probability of missing grabbing problems is destined to be a greater clinical saying, saying that coronary angiography is the gold standard for diagnosing coronary heart disease."

"She remembered the numbers very firmly." Dr. Zhao grabbed the back of the chair and exclaimed.

Dr. Xu snapped and took a picture of his student's head: Do you praise others and think of yourself?

Dr. Zhao touched his head and was slapped by the teacher and smiled. He didn't care. He needed to learn from each other in medicine. There must be my teacher when he walked through three people.
