Magnetic resonance can check early cerebral edema, cerebral hemorrhage and brain parenchymal injury caused by head impact, but there are some head impact related injuries that cranial MRI cannot check, such as mild concussion.
1. Magnetic resonance can make early diagnosis of cerebral edema and cerebral hemorrhage: magnetic resonance uses hydrogen proton as the imaging principle, so magnetic resonance examination is very sensitive to intracranial cerebral hemorrhage and cerebral edema, so magnetic resonance can make early diagnosis of cerebral edema and cerebral hemorrhage secondary to head impact injury.
2. Magnetic resonance can detect minor cerebral hemorrhage: magnetic resonance can detect minor cerebral hemorrhage secondary to head trauma through T1W1, T2W2 and FLAIR sequences, etc. Therefore, cranial magnetic resonance can not only examine head impact injury, but also diagnose minor cerebral parenchymal injuries secondary to head impact injury.
3. Magnetic resonance has high resolution for soft tissues and does not have rays that can damage the human body: Magnetic resonance has very high resolution for the brain and other human brain parenchyma, so MRI can be used to examine head impact injuries, and in addition, magnetic resonance can be used for further diagnosis of other head impact injuries that can not be typed.
4. Injuries that cannot be detected by cranial MRI: concussion caused by head impact cannot be detected by cranial MRI, and this type of injury needs to be diagnosed mainly according to clinical manifestations.
It is recommended that patients who have suffered head impact should consult the doctor in time, and choose imaging examination such as cranial magnetic resonance imaging (CMRI), CT and other related examinations under the doctor’s guidance, so as to make early diagnosis and treatment of the disease to avoid delaying the condition.
