头痛做CT好还是核磁共振 张春志 吉林省脑科医院

头痛做CT好还是核磁共振 张春志 吉林省脑科医院 要根据具体头痛的原因来选择做CT或者磁共振，如果是急性外伤引起的头痛，可以先做CT检查，排除一下颅内损伤或者出血，其他原因引起的头痛，最好做核磁共振检查，核磁共振在检查血管神经等方面引起的头痛效果优于CT。两者都是目前颅脑疾病，主要的影像学检查方法，但各有优势，互相补充，CT检查速度快，对于急性脑出血，颅内钙化的检测最为敏感，但对于24小时以内的急性脑梗死不易显示，而核磁共振也就是MR，对数小时内的超急性脑梗塞，以及对亚急性脑出血显示敏感，由于MRI具有非常高的原组织分辨率。已经在颅脑疾病，以及在其他部位检查方面得到广泛应用，MRI检查时间长，体内如果有铁磁性物质属于禁忌症，作颅脑CT或核磁共振检查时，可以诊断头部疾病，不过核磁共振较CT更有优越，因为核磁共振检查没有辐射，对想要孩子的孕妇，都可以检查的，另外核磁共振对发现病变也比CT敏感，对定性也有优势，而且核磁共振能分辨出梗塞是新鲜的还是陈旧的，总之核磁共振要明显优于CT检查的。 CT or MRI for headache CT or MRI should be selected according to the cause of headache, If it's an acute traumatic headache, You can do CT first, Remove the intracranial injury or hemorrhage, Headaches from other causes, It's better to have an MRI, MRI is better than CT in the examination of blood vessels and nerves. Both are current brain diseases, Main imaging examination methods, But each has its own advantages, Complement each other, CT examination is fast, For acute cerebral hemorrhage, The detection of intracranial calcification is the most sensitive, However, it is not easy to show acute cerebral infarction within 24 hours, And nuclear magnetic resonance is Mr, Hyperacute cerebral infarction within several hours, And sensitive to subacute cerebral hemorrhage, Because MRI has very high original tissue resolution. It's a brain disease, It is widely used in other parts inspection, MRI takes a long time, If there are ferromagnetic substances in the body, they are contraindications, For brain CT or MRI, It can diagnose head diseases, But MRI is better than CT, Because there was no radiation in the MRI, For pregnant women who want to have children, It can be checked, In addition, MRI is more sensitive than CT in detecting lesions, It also has advantages in qualitative analysis, And MRI can tell if the infarct is fresh or old, In a word, MRI is better than CT.
