Benign tumors usually appear as regular masses, and most of them are round or oval, and the borders of benign tumors are usually clearer. Usually, benign tumors will not invade the surrounding normal tissues and structures, and will not have obvious enlargement of the surrounding lymph nodes or metastasis to other parts of the body. It is generally difficult to identify benign or malignant tumors through MRI scanning, and patients need to undergo further MRI enhancement. In the enhanced MRI, benign tumors usually do not show significant or delayed enhancement. If the tumor is malignant, most of them show uniform or uneven enhancement phenomenon, and this kind of enhancement tends to appear earlier. It should be noted that if the patient has a pacemaker, metal dentures and other objects in the body, this group of people is not suitable for magnetic resonance examination. Treatment should be carried out under the guidance of the doctor, follow the doctor’s instructions and actively cooperate with the doctor’s treatment, avoiding the patient’s self-medication.
