MRI has a wide range of examinations, which can check neurological diseases, thyroid diseases, liver and gallbladder diseases, vascular diseases, and bone and joint system lesions. 1. Neurological diseases: Neurological tumors, trauma, congenital malformations, and hemorrhagic or ischemic diseases can be diagnosed qualitatively by MRI. 2. Thyroid diseases: it can assist in checking the nature of thyroid nodules or lumps, such as thyroid cancer and thyroid cysts. 3. Hepatobiliary diseases: MRI can assist in the diagnosis of liver cysts, hepatic schistosomiasis, liver cancer, gallstones, gallbladder polyps and other diseases. 4. Vascular diseases: MRI angiography can also clarify the conditions of hemangioma and blood vessel stenosis. 5. Bone and joint system lesions: MRI has high diagnostic value for bone infection, tumor, trauma and lesions of cartilage, ligament, meniscus, synovium, bursal fluid and other tissues in joints. MRI is also able to examine, for example, brain and spinal cord diseases, and has a significant advantage over CT in lesions in the posterior cranial fossa such as the brainstem and cerebellum, as well as soft tissue diseases such as the spinal cord and intervertebral discs.
