Dye txhaj tshuaj myelogram nyob qhov twg?

Yuav ua li cas yog txoj hauv kev ntawm kev tswj hwm qhov sib txawv hauv myelography?
Myelography entails kev tshuaj ntsuam xyuas ntawm tus txha nraub qaum tom qab intrathecal instillation ntawm iodinated contrast media los ntawm ob lub lumbar puncture lossis lub ncauj tsev menyuam ntawm theem C1-C2, tom qab mus rau qaum qaum. Dej-soluble,nonionic contrast agents yog siv tshwj xeeb.
