486 Colorful Brains

The shape of the brain under the MRI image can be faintly seen in the film.

This is DTI technology, and although Gao Baixiang is not a doctor in neurology, he knows something about it.

Scatter tensor imaging, or DTI, is the only new imaging technique that can show the passage of white matter fiber tracts in vivo, which can examine the integrity of the corticospinal tract (CST).

The application of this technology in the study of the brain has only begun in recent years.

About 1 year ago, Gao Baixiang's circle of friends was swiped and marked as the most beautiful brain.

The so-called most beautiful brain is nerve fiber beam imaging, and the image data of the human brain after a series of technical processing is no longer only black and white, but colorful forms.

Gao Baixiang remembered this deeply, he watched the many neurology professors and directors of the Medical University sigh and wail in the group, and he didn't know when the Medical University could enter a similar machine so that they could also operate it themselves, and felt a little funny.

This is the world's most cutting-edge medical technology, if it is introduced in China, I am afraid that it will not take 5-10 years?

Unexpectedly, I saw this technology at Jianxie Hospital 1 year later.

Mr. Wu is really at the forefront of technology, and DTI technology is ...... Thinking about it, Gao Baizhi watched Wu Mian squatting on the ground in a military posture through the leaded glass, concentrating on what to do with the parts in one place, and he was at a loss in his heart.

Wei Dabao didn't know anything about DTI technology at all, and the images were reflected in his eyes, colorful and colorful, like a butterfly soaring on a computer screen.

"Director Gao, what is this?" Wei Dabao asked a little confused.

"It's an MRI image of the head of a white rabbit used for testing. ”

"It's an MRI?!" Wei Dabao had a hard time combining the black and white, monotonous and esoteric NMR images with the colorful moving images in front of him.

"Well, so to speak. Gao Baixiang no longer ignored Wei Dabao and asked the technician: "Xiao Zou, what is Teacher Wu doing?" ”

"Mr. Wu wrote a software by himself, and after entering it, he tried running it, but the machine crashed after a few seconds of running. The technician said helplessly, "Director Gao, I didn't expect the latest high-end machine like the SIGNA Architect 3.0T to collapse. ”

"Why did you collapse?" Gao Baixiang asked kindly.

"You look at the image ......" said, the technician suddenly realized that he was too attentive to the MRI gifs just now, and Gao Baixiang was still standing on the side, and quickly stood up, "Director Gao, I'm sorry, I'm too attentive, you sit, you sit." ”

"You sit and say. Gao Baixiang pressed the technician's shoulder and said with a smile, "Tell me what's going on." ”

"Uh...... Mr. Gao, how do you explain this? ”

"I don't have any foundation, I'm in circulation, I rarely watch MRI, you try to explain in detail. Gao Baixiang understood what the technician meant.

"Human memory, vision, sensation, movement, etc. are stored in neurons in the cerebral cortex, and different neurons have different nerve fiber bundles to connect them in series or parallel, and in addition to the integration and analysis of the brain's thalamus and gray matter nuclei and other complex circuit regulation, so as to achieve our free action. ”

"Look here. ”

The technician said, clicking the button, and the GIF stopped.

"Here's the sensory bundle, here's the motor bundle. In the anesthetized state, the activity of sensory and motor nerve fiber bundles is poor, while the active memory nerve fiber tract is active. ”

"Rabbits have memories, too?!"

"Normally, yes. The technician scratched his head, "Hehe, I don't know." I asked Mr. Wu just now, and that's what he said. ”

"Here are the projection fibers, which are the fibers that connect the deep nuclei of the cerebral cortex to the brainstem, cerebellum, and spinal cord, including afferent and efferent fibers. Typical representatives include corticospinal tract, corticopontine tract, corticobulbar tract, optic radiation, etc. ”

"Here are the liaison fibers, which are the fibers that connect the cortex of the ipsilateral hemisphere, which are divided into intracortical and subcortical contact fibers, which are divided into short fibers and long fibers, and also include cingulate, upper and lower longitudinal bundles, hook bundles, and upper and lower frontal occipital bundles. ”

"Here are the symphysis fibers, which connect the cortex of the cerebral hemispheres on both sides, including the corpus callosum, the anterior symphysis, and the fornix symphysis. ”

The technician said, pointing to the colorful patterns on the screen.

"That's all I know. The technician said with some embarrassment, "DTI technology is too new, yesterday Mr. Wu told me to let me learn and gave me some information." After watching it all night, I remembered it. ”

"It's good. Gao Baixiang patted the technician's shoulder and said, "Is there a problem with Mr. Wu's software?"

When he said this, Gao Baixiang was a little confused. Isn't writing software what engineers at GE Healthcare should do?

"I don't think so. The technician shook his head, "It should be that Mr. Wu's requirements are too high, and GE's SIGNA Architect 3.0T NMR machine is overloaded, causing the machine to shut down." ”

"Oh, Director Gao. ”

As he spoke, the technician gestured to the image.

"If there was a problem with the program, there would not be a GIF for a few seconds. ”

"Originally, DTI data processing was to import the raw scan data into GE's ADW4.6 workstation, and then use Fune Tool software for post-processing to obtain ADC and FA diagrams, and reconstruct the white matter fiber bundle map. But for some reason, Mr. Wu wrote a software by himself, and did not use GE's ADW4.6 workstation and Fune Tool software. ”

Gao Baixiang shook his head, Mr. Wu is not only good at medical treatment, but also understands engineering equipment. This point, when he was in Pengcheng, the time when the blood oxygen saturation clip could not measure the value, Gao Baixiang understood.

Now Mr. Wu even disassembles and reassembles the latest NMR, without the need for GE engineers.

What this means, Gao Baixiang knows too well.

The first DSA machine that was imported from the second hospital of the former medical university broke down once and had to be repaired by the manufacturer. But at that time, there was no competition, and it was a state of big bullying in the store, and the engineer of the manufacturer flew over after 22 days.

They took a look at it, changed the parts, and it didn't take 10 minutes before and after, charging 250,000 yuan.

There are many more similar things.

Looking at Mr. Wu, who was squatting on the ground and concentrating on fiddling with GE's SIGNA Architect 3.0T nuclear magnetic machine, Gao Baixiang had mixed feelings in his heart.

"Director Gao. Wu Mian shouted inside.

"Eh!" Gao Baixiang hurriedly walked in.

"It's okay, you can go back first, and give medicine to the patients with Takayasu's arteritis. Conventional medication is fine, nothing special. Don't wait for me here, and neither does Dr. Wei. ”

"When are you going to get it?" asked Gao Baixiang.

"Reassemble and try again. The software may need to be modified, I overestimated GE's machine, it was too detailed to run. It would be nice if it could be customized, almost. At that time, if you found out the problem before the crown prince came to the operation, you directly asked for a ready-made one. ”

"......" Gao Baixiang was speechless.

[I have crossed the mountains and the sea......]

Wu Mian's mobile phone rang, and he stood up and picked up the phone to connect.

"Boss Tao, rare guest, what do you instruct. Wu Mian laughed casually.
