Nrov science paub txog kev kuaj ultrasound - qhov txawv ntawm "B-ultrasound" thiab "xim ultrasound"
Thaum lub sij hawm niaj hnub kuaj ultrasound, peb pom tias ntau tus neeg mob yuav nug "Tus kws kho mob, koj puas yog xim ultrasound? Vim li cas nws thiaj li dub thiab dawb?". Feem ntau hu ua "B-ultrasound", nws siv qhov kev sojntsuam los sojntsuam thiab xa rov qab thiab tau txais cov kab hluav taws xob ultrasonic los ua ib daim duab ntawm ob sab uas pom ntawm qhov screen, uas yog, ob-seem ultrasound. Grey-scale cross-sectional duab ntawm lub cev qauv thiab morphology.
Ultrasound imaging siv grayscale hloov los ntawm dawb mus rau grey mus rau dub los qhia cov kev hloov nyob rau hauv lub cev lub zog ntawm lub cev los yog cov kab mob, xws li cov kua uas tshwm nyob rau hauv dub, gallstones, pob txha los yog gas tshwm nyob rau hauv cov xim dawb; vim qhov ceev ceev ultrasound imaging ceev, Nws tuaj yeem tso saib qhov xwm txheej ntawm lub cev hauv lub sijhawm; Ob-dimensional ultrasound muaj kev taw qhia: cov duab grey-teev ntawm XY axis hlais nce, nqis, sab laug, sab xis, pem hauv ntej, thiab nraub qaum, thiab Z axis yuav tsum tau kuaj peb-dimensional.
Nrog rau kev txhim kho kev kho mob maj mam, ntau lub tsev kho mob loj dua tau tshem tawm qhov yooj yim ob-dimensional ultrasound ntsuas thiab hloov nws nrog xim Doppler ultrasound kuaj system. Tib neeg hu nws "xim ultrasound". Cov qauv sib txawv xws li lub plawv, peb sab, thiab lwm yam, xim Doppler tiag tiag suav nrog B-ultrasound, xim Doppler, M-hom echocardiography thiab lwm yam kev soj ntsuam thiab tshuaj xyuas software. Kev ua haujlwm thiab qhov kev thov muaj feem cuam tshuam nrog kev teeb tsa tshwj xeeb ntawm cov cuab yeej. Kev ua haujlwm ntawm ultrasound thiab xim ultrasound raug cais.
Cias muab tso, "xim Doppler" yog ib tug high-txhais dub thiab dawb B-ultrasound ntxiv rau xim Doppler. Nws cov txiaj ntsig tseem ceeb yog: nws tuaj yeem ua tau sai thiab intuitively tso saib ob sab dav hlau faib cov ntshav khiav; nws tuaj yeem tso saib kev khiav ntawm cov ntshav khiav; Nws yog qhov zoo rau kev paub qhov txawv ntawm cov hlab ntsha thiab cov hlab ntsha; Nws yog qhov zoo los txheeb xyuas cov kab mob vascular thiab cov kab mob uas tsis yog vascular; Nws muaj txiaj ntsig zoo kom nkag siab qhov xwm txheej ntawm cov ntshav ntws Nws tuaj yeem nkag siab yooj yim lub sij hawm theem thiab ceev ntawm cov ntshav khiav; tuaj yeem ntseeg tau pom shunt thiab reflux; tuaj yeem txheeb xyuas qhov ntau, qhov dav, qhov ntev thiab thaj tsam ntawm cov ntshav ntws. Cov kev tshwm sim ntawm ultrasound thiab qhov tsis ua haujlwm ua lub luag haujlwm tseem ceeb hauv kev kuaj mob ntawm cov kab mob.
"Color Doppler" tuaj yeem pom cov kev hloov pauv ntawm cov ntshav perfusion hauv cov kabmob lossis cov kab mob, paub qhov txawv ntawm cov khoom lossis cov cystic pawg, thiab ua kom raws li cov kev hloov pauv ntawm cov ntshav ntws spectrum ntawm cov phab ntsa cyst thiab cov khoom loj, xws li cov ntshav khiav nrawm, zoo li, tsis kam. , thiab cov yam ntxwv ntawm cov ntshav perfusion Lub hauv paus siv rau kev kuaj mob zoo, xws li cov khoom siv tsis tshua muaj zog muaj ntau dua hauv cov qog nqaij hlav malignant.
"Color Doppler" los txiav txim siab cov kev hloov pauv hemodynamic ntawm cov hlab plawv system: sau lub xeev, ntshav ntws xim, kev taw qhia, kev ceev, siab, theem, sijhawm, ntws, thiab lwm yam rau kev kuaj mob; xws li me me atrioventricular septal defects, ob-dimensional Ultrasound tej zaum yuav tsis qhia qhov sib txawv, tab sis ib zaug cov xim Doppler siv, lub shunt ntawm qhov tsis xws luag tuaj yeem pom meej meej, uas plays lub luag haujlwm tseem ceeb hauv kev kuaj mob; Lwm qhov piv txwv yog lub plawv valve stenosis thiab vascular stenosis, thaum cov ntshav ntws dhau los ntawm stenosis. , Vim tias qhov nce ntawm qhov sib thooj siab, ntau lub dav hlau mosaic yuav tshwm sim nyob rau hauv lub stenotic orifice thiab lub distal kawg. Cov kws kho mob tuaj yeem ntsuas thaj tsam ntawm lub valve los ntawm kev ntsuas lub sijhawm ib nrab ntawm kev poob siab los ntawm spectral Doppler.
Yog li, qhov sib txawv ntawm "xim ultrasound" thiab "B ultrasound" tsis tuaj yeem sib npaug ntawm qhov sib txawv ntawm cov xim TV thiab dub thiab dawb TV. Kuv vam tias cov kev paub me me no tuaj yeem pab tau zoo rau feem coob ntawm cov neeg mob kom nkag siab zoo dua qhov txawv ntawm "xim ultrasound" thiab "B ultrasound".
