Xim zas xim yog kev daws teeb meem uas yog siv kom ua kom pom tseeb cov qauv tshwj xeeb thaum saib ntawm lub cev. Radiocontrast agents yog cov tshuaj uas yog siv hauv kev tshawb fawb xws li X-rays, fluoroscopy, thiab suav tomography (CT) kuaj.
Ib yam nkaus, tib neeg nug, dab tsi yog qhov cuam tshuam ntawm cov xim sib txawv?
Iodine-based Contrast Materials
- xeev siab thiab ntuav.
- mob taub hau.
- khaus.
- yaug
- tawv nqaij me me lossis khaus khaus.
Ib qho ntxiv, dab tsi yog qhov sib txawv zas xim ua los ntawm? Nws tuaj yeem yog cov khoom siv iodine-based, barium-sulfate, gadolinium, lossis ntsev thiab cua sib xyaw uas tuaj yeem nqos tau los yog txhaj tshuaj ncaj qha. Zoo ib yam sib txawv, lossis "sib txawv," nruab nrab ntawm cov kabmob, nqaij, pob txha, lossis cov hlab ntshav thaum koj kuaj mob.
Hauv qhov no, vim li cas lawv thiaj txhaj tshuaj zas xim rau CT scan?
Rau qee leej CT kuaj tej zaum koj yuav tsum muaj txhaj tshuaj ntawm tshwj xeeb zas xim hu ua intravenous contrast. Qhov no pab qhia pom qee qhov ntawm lub cev tsis pom tseeb, zoo li cov hlab ntshav, ob lub raum thiab daim siab. Qhov sib piv yog cov dej ntshiab feem ntau txhaj rau hauv txoj hlab ntshav ntawm caj npab tam sim ua ntej luam theej duab.
Ntev npaum li cas qhov sib txawv zas xim nyob hauv koj lub cev?
Nrog rau lub raum ua haujlwm ib txwm, feem ntau ntawm gadolinium raug tshem tawm los ntawm koj lub cev hauv cov zis hauv 24 teev. Yog tias koj muaj lub raum tsis ua haujlwm lossis mob raum mob hnyav thiab tau txais gadolinium-based sib txawv tus neeg sawv cev, tej zaum yuav muaj kev pheej hmoo me me ntawm kev tsim cov xwm txheej tsis tshua muaj.
