The severity of the disease cannot be determined only by the high signal of T2flair in the brain. The severity of the brain lesion should be determined not only by the MRI performance, but also by the combination of cranial CT, examination of cerebrospinal fluid, physical examination, and the patient’s clinical manifestations.
T2flair is a technique that suppresses the T2 high signal (long T2) of the cerebrospinal fluid in T2-weighted (mainly reflecting the difference in T2 values between tissues) magnetic resonance imaging, so that adjacent cerebrospinal fluid lesions with high signals can be displayed more clearly.
T2flair high signal is seen in most intracranial primary tumors, brain metastases, infarct foci, soft foci, demyelinating lesions, cerebral edema, brain abscesses, epidermoid cysts, fatty tumors, and subacute stages of cerebral hemorrhage.
In conclusion, it is not possible to determine the severity of the lesion by relying only on the results of T2flair in the brain, and it is recommended that the patient go to the hospital in time to clarify the cause of the disease under the guidance of the doctor and receive prompt treatment.
