A myelogram yog ib qho kev kuaj pom kev kuaj mob feem ntau ua los ntawm tus kws kho hluav taws xob. Nws siv contrast dyethiab X-rays lossis xam tomography (CT) txhawm rau saib cov teeb meem hauv tus txha caj qaum.

Kev sib piv twg yog siv hauv myelography?

iodine: cov khoom tsis yog xim hlau siv los ua tus neeg sawv cev sib txawv uas ua rau cov hlab ntsha thiab cov ntaub so ntswg nthuav tawm ntawm kev kuaj pom (angiogram, CT, myelogram).

Qhov sib txawv yog siv rau CT myelogram?

Ib tus myelogram ua ntej hauv ib txoj kev sib cais. Qhov no zoo ib yam li lub lumbar puncture, los yog tus txha caj qaum, qhov chaw ntawm cov kua dej nyob ib ncig ntawm tus txha caj qaum (nyob rau hauv tus txha caj qaum) yog nkag nrog tshuaj loog hauv zos thiab sib piv ( feem ntau 12cc uas tsis yog-ionic iodinated sib piv) yog tswj hwm.

Ntau npaum li cas qhov sib piv yog siv rau myelogram?

Lub tshuab X-ray yuav siv los coj tus kws kho hluav taws xob nrhiav qhov chaw txhaj tshuaj thiab hla lub koob mus rau qhov chaw no. Iodine uas muaj qhov sib txawv nruab nrab, feem ntau yog kwv yees li 10 mL, tom qab ntawd txhaj rau hauv cov kua dej ncig ntawm tus txha caj qaum.

qhov sib piv nruab nrab txhaj rau lub myelogram nyob qhov twg?

Cov khoom sib piv feem ntau yog txhaj rau hauv lub lumbar qaum qaum kwj dej, vim nws suav tias yooj yim dua thiab nyab xeeb dua. Qee lub sij hawm, yog tias nws pom tias muaj kev nyab xeeb dua lossis siv tau ntau dua, cov khoom sib txawv yuav raug txhaj rau hauv lub ncauj tsev menyuam qaum.
