核磁共振一年内不能超过几次为好 李伟东 吉林省脑科医院
核磁共振是利用核磁共振的原理，通过外加梯度磁场，发射出的电磁波收集数据，形成人体内各部各组织的结构图像来用于诊断的。核磁共振是一种高端的应用设备，对疾病有很高的诊断价值，而且能够对肿瘤的预后和治疗后的效果评估给予很大的帮助，它和X线CT相比优点在于对人体没有任何伤害、安全、快速、准确的临床诊断方法，核磁共振的检查费用较贵，在检查时有一定的噪声，会给受检者带来一定的不适，对于怀孕3到6个月的妇女尽量不要做核磁共振检查，必须检查时要充分评估风险与利益，所以若有诊断和治疗方面的需要，每年做几次没有一定的标准，主要是根据疾病的具体需要，决定是否做核磁共振的检查。

It's better not to have more than one MRI in a year
Nuclear magnetic resonance is based on the principle of nuclear magnetic resonance, Through an external gradient magnetic field, The emitted electromagnetic wave collects data, To form structural images of various tissues in human body for diagnosis. Nuclear magnetic resonance is a high-end application equipment, It has a high diagnostic value for diseases, Moreover, it can give a great help to the prognosis of the tumor and the evaluation of the effect after treatment, Compared with X-ray CT, it has the advantages of no harm, safety, fast and accurate clinical diagnosis method for human body, The cost of MRI is relatively high, There is certain noise during inspection, It will bring certain discomfort to the examinee, Try not to do MRI for women who are 3 to 6 months pregnant, Risks and benefits must be fully assessed when inspection is necessary, So if there's a need for diagnosis and treatment, There is no standard for doing it several times a year, Mainly according to the specific needs of the disease, Decide whether to have an MRI.
