There are better medical equipment than magnetic resonance imaging.

Yes, there is. Such as PET-CT. As far as I know, Siemens' PET-CT 64 is the latest, fastest and highest resolution PET-CT. Traditional imaging equipment such as CT, magnetic vibration and ultrasound are not comparable. You can create a clearer and more dynamic image and locate it accurately, and you can get the highest resolution whole-body tomographic image in just over ten minutes. Especially for head and neck tumors, lung tumors, breast cancer, digestive tract malignant tumors, etc., it also plays a very important role in Alzheimer's disease, Parkinson's syndrome, epilepsy, coronary heart disease and so on.
