MRI = magnetic resonance imaging 完全靠磁场成像怎么会有辐射呢? MRI scanners are particularly well suited to image the non-bony parts or soft tissues of the body. They differ from computed tomography (CT), in that they do not use the damaging ionizing radiation of x-rays. https://www.nibib.nih.gov/science-education/science-topics/magnetic-resonance-imaging-mri
因为不同的症状。第一次做了看了没事。第二次是因为别的症状,所以再做一次确保没事。
是要加造影吗,不然症状再变,照片还不一样的吗,照完了想看鼻子还是想看眼睛,再拿出来看就行了
请问MRI没有辐射吗? 我怎么查到有辐射,难道我差错了。。。。

MRI 要预约,没有那么快。 所以就上CT
