Cov xov xwm sib pivyog ib pawg tshuaj lom neeg uas tau tsim los pab txheeb xyuas tus kab mob los ntawm kev txhim kho qhov kev daws teeb meem ntawm kev thaij duab. Cov tshuaj sib piv tshwj xeeb tau tsim rau txhua hom kev thaij duab, thiab txhua txoj kev siv.
"Cov khoom siv sib piv (contrast media) yog qhov tseem ceeb heev rau qhov txiaj ntsig (uas) kev siv tshuab thaij duab ntxiv," Dushyant Sahani, MD, tau hais hauv kev xam phaj video tsis ntev los no nrog Joseph Cavallo, MD, MBA.
Siv dav dav
Rau kev thaij duab suav nrog (CT), kev thaij duab magnetic resonance imaging (MRI) thiab positron emission tomography computed tomography (PET/CT), cov tshuaj sib piv siv rau feem ntau ntawm cov kev kuaj mob no rau kev thaij duab plawv thiab kev thaij duab oncology hauv chav kho mob ceev.
Cov Neeg Sawv Cev Sib Piv Rau Cov Hom Phiaj Sib Txawv
Muaj ntau hom tshuaj sib piv siv hauv ntau lub chaw haujlwm duab kho mob sib txawv.
Barium sulfateCov tshuaj sib piv tau siv rau ntau xyoo lawm. Feem ntau lawv siv rau kev kuaj mob radiographic thiab fluoroscopic xwb. Qee zaum lawv kuj siv rau kev kuaj CT ntawm txoj hnyuv plab. Lawv pheej yig thiab feem ntau cov neeg mob tsis tas siv tshuaj, thiab cov teeb meem los ntawm kev siv lawv tsis tshua muaj.
Cov tshuaj sib piv iodineyog cov tshuaj sib piv uas muaj cov iodine atoms siv rau kev thaij duab hluav taws xob, fluoroscopic, angiographic thiab CT imaging. Lawv yog ib pawg tshuaj siv tau ntau yam rau kev txhaj tshuaj rau hauv cov hlab ntsha, noj thiab lwm txoj kev txhaj tshuaj. Lawv kuj tseem siv tau rau hauv fluoroscopy, angiography thiab venography, thiab qee zaum, kev thaij duab hluav taws xob yooj yim.
Cov tshuaj sib piv MRIFeem ntau yog cov tshuaj sib piv gadolinium (GBCAs), uas yog cov tshuaj siv rau feem ntau ntawm kev ntsuas MRI uas muaj kev sib piv. Keeb kwm, lawv qee zaum siv rau kev ntsuas vascular thiab CT tab sis vim yog nephrotoxicity qhov kev siv no tau raug tso tseg (feem ntau) lawm.
Cov khoom siv sib piv ntawm Ultrasoundtau txais kev rub tawm hauv xyoo tas los no rau cov ntawv thov niche feem ntau.
Tej zaum yuav muaj tej yam tshwm sim los ntawm kev txhaj tshuaj contrast?
Feem ntau cov tshuaj pleev xim yuav tsis ua haujlwm tam sim ntawd, tab sis qee zaum yuav muaj pob liab, khaus (Kev ua xua me ntsis) tshwm sim rau ntawm lub cev ob peb teev tom qab kev luam theej duab. Qhov no tsis tshua muaj, tab sis yog tias nws tshwm sim, koj yuav tsum tiv tauj koj tus kws kho mob lossis chav kho mob ceev hauv zos.
Lwm yam kev tsis haum tshuaj uas tsis tshua muaj tab sis tej zaum yuav tshwm sim qeeb xws li xeev siab, ntuav, mob plab, tawm pob, kiv taub hau thiab mob taub hau. Cov cim thiab tsos mob no yuav luag ploj mus li ob peb teev thiab feem ntau tsis tas yuav kho mob ntau.
Cov Tshuaj Txhaj Tshuaj Sib Piv
Cov Tshuaj Txhaj Tshuaj Sib Pivsiv los txhaj tshuaj contrast media lossis cov tshuaj contrast agents kom txhim kho cov ntshav thiab perfusion hauv cov nqaij. Contrast feem ntau piav qhia tias yog 'xim' vim nws tso cai rau cov leeg, cov hlab ntsha thiab cov kabmob sab hauv kom pom tseeb dua ntawm cov duab scan. Qhov no yog ua tsaug rau kev pab ntawmlub tshuab txhaj tshuaj siabs. LnkMed tau tshaj tawm nws covCT ib lub tshuaj txhaj, CT ob lub taub hau injector, MRI txhaj tshuaj, Angiography txhaj tshuajmus rau hauv kev ua lag luam ib kauj ruam zuj zus txij li thaum nws tau tsim tsa xyoo 2018 thiab peb tau txais ntau tus neeg siv khoom.
