There is a difference between the results of MRI 1.5T and 3.0T. 3.0T has a higher detection rate of micro-hemorrhages in the brain compared to 1.5T MRI, which allows for better screening for hidden problems in the patient’s body. Currently, there are two types of MRI in China: 1.5T and 3.0T. Generally speaking, the higher the magnetic field of MRI, the better it is. 3.0T MRI has better spatial resolution, image quality and enhancement effect than 1.5T, and has a higher detection rate of microhemorrhage in the brain. However, 3.0T MRI is also more likely to produce artifacts. Therefore, 1.5T MRI is generally recommended for patients who are undergoing routine checkups or have metal fixation in the body. For patients with specific diseases, a 3.0T MRI is recommended for better screening. Therefore, when choosing between the two MRIs, the doctor will usually make the decision based on the patient’s specific condition and financial situation.
