小孩做磁共振检查对身体有损害吗 李强 重庆市綦江区人民医院

小孩做磁共振检查对身体有损害吗 李强 重庆市綦江区人民医院 小孩做磁共振是没有任何伤害的，磁共振的成像原理是对人体组织发射一个射频脉冲后，氢原子吸收热量，然后释放出来通过计算机处理得到一个不同信号的图像，所以它没有任何电离辐射，现有证据证明它对小孩是没有任何伤害的，包括胎儿、刚刚出生的婴儿、儿童都可以完全放心的做磁共振检查，唯一不好的是因为磁共振噪音大，有的小孩在做的时候就会不配合、会动，动的时候就会产生很大的伪影，影响图像质量，对于无法配合的小孩是需要镇静的。 Is MRI harmful to children's health There's no harm in a child's MRI, The principle of MR imaging is to send a radio frequency pulse to human tissues, Hydrogen absorbs heat, And then it's released and processed by computer to get an image of a different signal, So it doesn't have any ionizing radiation, There's evidence that it doesn't do any harm to children, Including the fetus, just born babies and children can be completely relieved to do MRI, The only thing that's bad is that MRI is noisy, Some children will not cooperate and move when they do it, When it moves, it will produce a lot of artifacts, Affect image quality, Children who can't cooperate need to be calm.
