I mainly want to check the brain and heart. How do I need to check it?
Answer:
ECG is the most commonly used method to check the heart, and M-mode ultrasound and color Doppler are also used. Check the brain is mainly CT, nuclear magnetic resonance vibration. These two items are more expensive, and they are related to the equipment in the hospital. The poor one may be 3 yuan, and the good one is more expensive!
