Xim Doppler ultrasound ua tau xim dub thiab dawb, thaum 3D thiab 4D xim Doppler ultrasound yuav yog khaki thaum ua cov duab 3D thiab 4D. Nws tsis yog xim Doppler ultrasound yog xim. Nws yog hu ua xim Doppler ultrasound vim tias nws siv cov xim cim rau cov cim taw qhia xws li lub siab thiab ntshav txaus.
1. Hemodynamics
Txhawm rau nws yooj yim, xim Doppler yog lub siab txhais cov xim dub thiab dawb B-ultrasound txuas nrog cov xim Doppler, uas tsis tsuas yog muaj qhov zoo ntawm ob-txheej txheem txheej txheem duab, tab sis kuj muab cov ntaub ntawv nplua nuj ntawm hemodynamics, uas tuaj yeem ua kom raug xav txog qhov muaj sia ntawm ntau yam plab hnyuv siab raum. Thiab cov ntshav ntws yam ntxwv hauv qab pathological.
2. Cov ncauj lus kom ntxaws txog kev txheeb xyuas lub cev ntau dua
Plaub lub ntsej muag xim Doppler ultrasound tuaj yeem soj ntsuam kev loj hlob thiab kev loj hlob ntawm tus me nyuam hauv plab los ntawm ntau cov lus qhia thiab lub kaum ntse ntse, muab lub hauv paus tseeb rau kev soj ntsuam thaum ntxov ntawm tus me nyuam hauv plab lub cev tsis zoo thiab ua rau lub siab yug ua ntej. Yav dhau los, cov khoom siv B-ultrasound tsuas tuaj yeem kuaj xyuas lub cev kev paub ntawm tus me nyuam hauv plab, thaum plaub xim xim Doppler ultrasound kuj tseem tuaj yeem kuaj xyuas lub cev hauv lub cev hauv lub cev, xws li lub qhov ncauj nqaj, spina bifida, lub hlwb, lub raum, lub plawv, pob txha tawv , thiab lwm yam, rau kev kho thaum ntxov.
3. Puas yog txoj hlab ntaws ncig ntawm caj dab kom pom tseeb dua?
Kev daws teeb meem ntawm cov xim Doppler ultrasound yog siab dua li ntawm cov xim dub thiab dawb B. Yog li, thaum kuaj cov ncauj lus kom ntxaws ntxiv, cov kws kho mob ntau txaus siab siv cov xim Doppler ultrasound. Piv txwv li:
Vim hais tias xim Doppler ultrasound tuaj yeem siv xim cim rau ntshav ntws, thaum txoj hlab ntaws caj dab ncig lub caj dab, koj yuav pom U-shaped lossis W-shaped ntshav ntws los rau koj tus menyuam' s caj dab. Nws yog qhov pom tseeb thaum lub zeem muag tias txoj hlab ntaws mus ncig lub caj dab.
Ordinary B-ultrasound kuaj ntawm txoj hlab ntaws txuas tsuas yog nyob ntawm kev soj ntsuam cov cim ntsuas siab tsim los ntawm cov kis, tab sis rau cov tsis pom tseeb, kev kuaj mob feem ntau ploj, yog li xim Doppler ultrasound tuaj yeem txiav txim tau zoo dua.
