MRI flat scan 1.5T, which represents the field strength of MRI is 1.5T. there are two main field strengths of MRI currently used in hospitals, 1.5T and 3.0T, of which 3.0T is stronger. 1.5T is usually used to examine common diseases, if doctors have special requirements or for scientific research, more 3.0T MRI is used, because the nuclear magnetic field strength of 3.0T is intensity is higher, the image quality is better, the detection time is shorter, and there are many functional imaging. However, because of the high field strength, it can cause some harm to the human body, and it is also more expensive and more demanding on the patient’s physical quality. So there are advantages and disadvantages to both types of field strength MRI. The doctor will consider which one to choose based on the patient’s examination purpose, physical condition, and financial situation.
