Chapter 219 [219] A question suddenly came

Xie Wanying is really "stupid" and always stands in it.

The teacher ran away, he was busy with something, let the students study by themselves.

She stood at the door of the control room, watching the two radiologists operate the instruments.

This is the MRI room. It takes the longest time to take an MRI film, which is longer than CT and X-ray. A cervical MRI sometimes takes an hour to scan. Not to mention that the patient is tired, the doctor is also tired.historical

When the equipment was working by itself, a female radiologist in her thirties went to get a thermos cup and poured water. Seeing her standing there alone, she was also curious: "Aren't you going outside to get some air?"

"It's okay, teacher, I can stand." Xie Wanying said.

A student who is different from other students, the female teacher told her: "Move yourself a chair and sit down."

Teacher is very nice, Xie Wanying moved a chair and sat down and continued to watch the instrument turn. Before her rebirth, she also studied in the radiology department and found it very interesting. Now, she looks at the graphics on the computer monitor, trying to get her brain to spin with the machine.

"Have you read the film?" the female teacher asked her.

"Try to read it." Xie Wanying said.

"Here's a picture, you tell me which part was taken." The female teacher took a picture next to her and showed her.

Xie Wanying took over the film and only glanced at it, it was obviously: "Cranial Brain."

Several undergraduate students outside the door noticed the teacher talking, and immediately walked in to join in the fun. Seeing the film in her hand, they said in unison, "This is all the brain of the photo."

Teacher, this question is easy.

"What else?" The female teacher smiled again, with an unfathomable expression on her face.

Several undergraduate students pondered the meaning of the teacher's words.

Xie Wanying replied directly: "This is a CT film, not a nuclear magnetic film."

Teacher was stunned for a moment, and looked at her with a different look in his eyes.

Several undergraduates blinked: not MRI but CT? This is an MRI examination room, not a CT examination room. Why is the teacher taking CT films?

"Can you tell the difference between CT and MRI?" The teacher asked again.

X-rays are definitely different from CT MRIs, you can see the difference at a glance. However, at first glance, CT films and MRI films are very similar. If they are not marked, they will be as indistinguishable as laymen who have not seriously studied radiology diagnostics.

The teacher asked you, which is equivalent to asking questions for all the trainees today.

Almost all the students were dumbfounded. They came to the radiology department for apprenticeships on the first day today, and they only attended one or two classes in the class, and the class teacher only had time to give an overview.

Some students may review the following homework in advance, but without the endorsement, they suddenly ask to answer the specific questions of this horizontal comparison.

Many students looked at each other in dismay.

The teacher saw it and smiled: "It seems that the teacher in the class didn't tell you. Can none of you answer it?"

If I came to traineeship for the first time and was looked down upon by the teachers collectively, it is estimated that the students in the two classes will become bad students in the word of mouth of the clinical teachers.

"Tell me about it." The teacher pointed to Xie Wanying, because she was the first to say that this was not a nuclear magnetic film.

"The MRI and CT films are both cross-sectional images, and the contrast of different shades of black to white shows the structure of each tissue. However, the imaging principles are different. CT films reflect the tissue electron density, X-ray attenuation coefficient, and MRI and The distribution of hydrogen protons in tissues and organs is related. Adipose tissue is black on CT, but white on MRI. Bone cortex is very white on CT, but dark on MRI. If the teacher brings another MRI of the same location, it is the same as the CT. Put the two together, and you can see the difference immediately."
