The presence of many white bright spots on an MRI requires a comprehensive judgment based on the sequence of the MRI. The appearance of white bright spots in the MRI examination may be a tumor or a manifestation of inflammation, which needs to be judged comprehensively based on the patient’s symptoms as well as the specific MRI slides. 1. Magnetic resonance films may show white highlights or black shaded areas. The diagnostic analysis of MRI uses the signal for description, and the white part indicates a high signal. 2. There are many series of MRI examinations, and it is important to look at the sequence of the examination to see in which sequence the high signal appears. It is also necessary to make a comprehensive judgment based on the part of the body being examined, for MRI of the brain as well as the liver and other parts of the body. If there is a high signal on the T2-weighted image and a low signal on the T1-weighted image, it may be a tumor. 3. Magnetic resonance examination can provide auxiliary reference for the diagnosis of tumors, but it cannot be used as the basis for confirming the diagnosis, nor can it clarify the nature and pathological types of tumors. Through magnetic resonance, it can determine the site of tumor growth, the size of the tumor tissue, and the relationship with the blood vessels and nerves of the surrounding tissues.
