Table 2 The application of special MRI sequences
Special MRI sequences | Recommended application scope and purpose |
|---|---|
Contrast enhanced MRI | Sturge–Weber syndrome, brain tumors, and vascular malformation; to determine the pathological diagnosis and extension of lesions. |
Diffusion tensor imaging | Unilateral lesions involving motor cortex or the whole hemisphere; to evaluate the distribution of the corticospinal tract and motor function compensability. |
DWI | During the sequelae stage of encephalitis, reviewing the DWI sequence in the acute stage of encephalitis is helpful for evaluating the extent of injury and potential epileptogenic zone in children. |
Magnetic sensitivity-weighted imaging | Cavernous hemangioma and Sturge–Weber syndrome; to display tiny intracerebral hemorrhage. |
