Sib piv mediayog ib pab pawg neeg ntawm cov tshuaj uas tsim los pab nyob rau hauv lub characterization ntawm pathology los ntawm kev txhim kho qhov sib piv daws teeb meem ntawm ib tug imaging modality. Cov xov xwm sib txawv tshwj xeeb tau tsim los rau txhua qhov qauv duab qauv, thiab txhua txoj kev tswj hwm kev xav tau.
Kev sib piv xov xwm yog ib qho tseem ceeb rau tus nqi (uas) cov txheej txheem duab ntxiv, "said Dushyant Sahani, MD, hauv kev sib tham video tsis ntev los no nrog Joseph Cavallo, MD, MBA
Kev siv dav
Rau kev suav tomography (CT), sib nqus resonance imaging (MRI) thiab positron emission tomography xam tomography (PET / CT), cov xov xwm sib txawv yog siv nyob rau hauv feem ntau ntawm cov kev kuaj mob plawv thiab oncology imaging nyob rau hauv lub chaw kho mob xwm txheej ceev.
Contrast Agents rau ntau lub hom phiaj
Muaj ntau ntau yam kev sib piv cov xov xwm siv nyob rau hauv ntau yam kev kho mob imaging department.
Barium sulfatecov xov xwm sib txawv tau siv ntau xyoo lawm. Lawv siv feem ntau txwv rau kev kuaj hluav taws xob thiab fluoroscopic. Qee lub sij hawm lawv kuj tau siv rau kev kuaj CT ntawm cov kab mob GI.Lawv pheej yig thiab ua tau zoo los ntawm cov neeg mob feem ntau, cov teeb meem ntawm lawv siv yog tsawg.
Iodinated sib piv mediayog cov neeg sawv cev sib txawv uas muaj iodine atoms siv rau radiographic, fluoroscopic, angiographic thiab CT duab. Lawv yog cov pab pawg ntau yam ntawm cov neeg ua haujlwm siv rau hauv cov hlab ntsha, qhov ncauj thiab lwm txoj hauv kev ntawm kev tswj hwm. Lawv tuaj yeem siv tau hauv fluoroscopy, angiography thiab venography, thiab qee zaus, radiography dawb.
MRI sib piv mediafeem ntau yog gadolinium-raws li contrast agents (GBCAs), uas yog cov neeg sawv cev siv rau feem ntau ntawm kev sib piv-txhim kho MRI scans. Keeb kwm, lawv tau siv qee zaus rau vascular thiab CT scans tab sis vim yog nephrotoxicity qhov kev siv no tau (loj heev) tso tseg.
Ultrasound sib piv mediatau txais traction nyob rau hauv xyoo tas los no rau feem ntau niche daim ntawv thov.
Dab tsi yog qhov tshwm sim los ntawm kev txhaj tshuaj ntawm qhov sib txawv?
Txhua yam tshuaj tiv thaiv rau cov xim yog ib txwm tam sim ntawd, tab sis qee zaus ib qho liab, khaus khaus (Ib qho tsis haum tshuaj me me) tuaj yeem tshwm sim ntawm lub cev qee teev tom qab kuaj xyuas. Qhov no tsis tshua muaj, tab sis yog tias nws tshwm sim, koj yuav tsum hu rau koj tus kws kho mob lossis chaw haujlwm A&E hauv zos.
Lwm yam uas tsis tshua muaj tab sis tuaj yeem ncua sij hawm muaj xws li xeev siab, ntuav, mob plab, ua pob, kiv taub hau thiab mob taub hau.Cov tsos mob thiab cov tsos mob yuav luag ib txwm ploj nyob rau ob peb teev thiab feem ntau yuav tsum tau kho me ntsis lossis tsis tas yuav kho.
Contrast Media Injector
Contrast Media Injectorsyog siv los txhaj tshuaj sib piv los yog cov tshuaj sib txawv los txhim kho cov ntshav thiab perfusion hauv cov ntaub so ntswg. Kev sib piv yog feem ntau piav raws li 'dye' raws li nws tso cai rau cov leeg, cov hlab ntsha thiab cov kab mob hauv nruab nrog cev kom pom tseeb dua ntawm cov duab scan. Qhov no yog tag nrho ua tsaug rau kev pab ntawmsiab injectors. LnkMed tau nthuav tawm nwsCT ib leeg injector, CT ob lub taub hau injector, MRI txhaj tshuaj, Angiography txhaj tshuajmus rau hauv kev ua lag luam ib qib zuj zus txij li thaum nws tsim nyob rau hauv 2018 thiab peb tau txais ntau tus neeg muas zaub.
