Medical equipment is as important as doctors.

It is generally recognized that ultrasound has the greatest influence, and there is no objection. What is the second one? I think it's all the same. The first is X-ray plain film, which is the most popular and perfect standard. It is not easy to shoot poorly, and it is even more difficult to shoot well! The more basic, the more level can be reflected! I stayed in the emergency department all the year round and met countless inexplicable patients all the year round. For various reasons, I can't cooperate with the filming. How to shoot questions in this situation? Very test the basic skills! The basic foot is oblique. How can someone break it? How to shoot if the leg is broken in a car accident and you can't lift it? How to shoot polio with twisted joints? Besides, MRI, water depth! There used to be a Daniel in our department. Just listening to the sound of magnetic resonance can tell what sequence you are scanning and what TR and TE are. Our colleagues should know how powerful this is. Finally, CT, we said that we only need to scan all the affected areas, and we can make a diagnosis through post-processing without leakage. But what about enhancement? The same Daniel 20 10 can make a very beautiful cardiac angiography with 15ml of iopamidol, which is still the old 64-layer GE VCT. I don't think most hospitals can persist until now. The benefits and difficulties of 15ml iodine for patients should be understood by all colleagues. Different doctors have different levels and the results are quite different. If I have to rank, I think B-ultrasound ranks first, because it is real-time and dynamic, which not only tests knowledge reserve, eyesight, but also tests technology. Compared with MRI, I think CT is more difficult, because in most cases, MRI may show more details and clarity than CT. To put it bluntly, the more advanced the technology, the more accurate the diagnosis. Automatic results only exist in laboratory tests, ultrasonic and radiological examinations. I don't think there will ever be a phenomenon that machines completely replace people. As an independent imaging subject, ultrasound is also operated by doctors, so finding lesions is subjective. So ultrasound has the greatest influence on the level of doctors.
