Tsis ntev tas los no, cov kws kho mob tau sau tshuaj ntau ntxiv rau kev kuaj ultrasound. Qhov nws tsis meej rau txhua tus, thiab cov ntawv luv luv qee zaum ua rau koj poob siab.

Yuav ua li cas txiav cov ntawv luv?

Kom nkag siab txog lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab lub tshuab ua haujlwm ntawm ultrasound (nws yog dab tsi thiab yuav kho nws li cas) yuav pab txiav txim siab: ultrasonic dopplerography ntawm cov hlab ntsha. Qhov no yog ib txoj hauv kev niaj hnub ntawm kev kuaj ultrasound ntawm cov kab mob hauv nruab nrog cev, raws li cov nyhuv Doppler.

UZDG MAG - yog dab tsi? Kev tshuaj xyuas ntawm cov hlab ntsha tseem ceeb ntawm lub taub hau, uas tso cai rau koj txheeb xyuas qhov nrawm thiab qhov xwm txheej ntawm cov ntshav ntws ntawm cov hlab ntsha tseem ceeb ntawm thaj chaw no.

UZDG BCS - yog dab tsi? Qhov no yog ib txoj hauv kev qhia txog kev kuaj cov vascular anomalies nyob rau hauv ob lub taub hau thiab caj dab kab mob.

USDG BCA - yog dab tsi? Qhov no zoo ib yam li kev kawm yav dhau los. Lo lus BCA (BCS) txhais tau hais tias cov hlab ntsha brachiocephalic (lub cev). Txoj kev no yog tsom rau kev tshuaj xyuas cov hlab ntsha loj-caliber uas txuas ncaj qha los ntawm aorta thiab nqa cov ntshav mus rau lub hlwb. Muaj peb txoj hlab ntsha brachiocephalic: carotid, vertebral thiab subclavian.

Mechanismua haujlwm

USDG yog ib qho kev tshawb fawb ua ke uas muab cov txheej txheem ultrasound txheej txheem thiab cov nyhuv Doppler thiab tso cai rau koj los saib ob lub xeev ntawm cov hlab ntsha thiab qhov xwm txheej ntawm cov ntshav ntws los ntawm lawv. Ultrasound angiography yog ua los ntawm kev siv suab nthwv dej uas nkag mus rau qhov tob ntawm tus neeg mob lub cev. Cov txheej txheem no tsis mob kiag li. Lub suab uas tsis hnov tsw rau tib neeg lub pob ntseg yog tawm thiab ntes los ntawm lub sensor tshwj xeeb. Thaum xav txog ntawm phab ntsa vascular, cov ntaub ntawv hloov dua siab tshiab los ntawm lub khoos phis tawj rau hauv cov duab dub thiab dawb ob sab. Doppler qhia txog cov khoom txav (cov qe ntshav liab) ntawm qhov screen hauv daim duab xim. Thaum lawv muab tso rau ntawm ib leeg, tau txais daim duab ultrasound.

Kev npaj ua ntej thiab kev kawm nyab xeeb

Y Siv ultrasound, nws tuaj yeem txiav txim siab lub xeev thiab qhov xwm txheej ntawm cov ntshav ntws hauv cov hlab ntsha ntawm ib qho caliber - los ntawm cov hlab ntsha loj thiab cov hlab ntsha mus rau qhov me tshaj plaws capillaries. Txoj kev kuaj no yog hais txog cov txheej txheem uas tsis muaj kev cuam tshuam. Txhawm rau ua txoj kev tshawb fawb, tsis tas yuav ua txhaum kev ncaj ncees ntawm cov qauv ntawm lub cev (piv txwv li, hauv laparoscopy, thaum muaj kev sib tsoo kom nkag mus rau laparoscope, lossis kev sib piv cov kev tshawb fawb siv X-rays, thaum tsim nyog rau qhia ib yam khoom rau hauv lub lumen ntawm lub nkoj). Cov yam ntxwv no ua rau ultrasound yooj yim li sai tau rau tus neeg mob thiab tus kws kho mob (tsis tas yuav muaj kev ua haujlwm nyuaj).

Ua ntej txoj kev tshawb fawb, tsis tas yuav muaj kev npaj tshwj xeeb - cov txheej txheem zoo ib yam li cov khoom siv ultrasound. Tus neeg mob yuav tsum tau nojtxoj hauj lwm xis nyob ntawm lub rooj zaum thiab nthuav tawm qhov chaw mus kuaj. Ultrasound scan yuav siv sij hawm 20 feeb mus rau 1 teev.

qhov kev kuaj no qhia rau cov neeg muaj hnub nyoog, nws tuaj yeem ua tau txawm tias cov menyuam yug tshiab, vim tias tsis muaj hluav taws xob cuam tshuam rau lub cev. Ultrasound yog suav hais tias yog ib txoj kev tshawb fawb muaj kev nyab xeeb thiab qhia tau zoo.

Cov qauv kuaj xyuas los ntawm ultrasound. Dab tsi yog Ultrasound Angiography?

Nrog kev pab los ntawm cov txheej txheem kho mob no, kuaj pom tus mob ntawm cov qauv hauv qab no:

  • vassel lumen;
  • tortuosity degree;
  • qhov xwm txheej ntawm phab ntsa vascular, nws txoj kev ncaj ncees thiab muaj cov ntsaws ruaj ruaj;
  • pathological nqaim (stenosis);
  • ua haujlwm tau zoo ntawm lub valve system ntawm cov leeg thiab muaj qhov tsis xws luag;
  • protrusion ntawm vascular phab ntsa;
  • obliteration (blockage) ntawm lub nkoj lumen los ntawm lub thrombus lossis txawv teb chaws lub cev;
  • ntshav ntws zoo - muaj, nrawm, turbulence.

Ultrasound angiography yog lub npe thib ob rau ultrasound, ntau dua, tab sis tsawg dua capacious.

Rau dab tsi pathologies yog ultrasound qhia?

yog dab tsi, peb txheeb nws tawm. Tab sis nyob rau hauv cov kab mob pathological dab tsi yog nws raug pom zoo los sau cov txheej txheem tshwj xeeb no txhawm rau kom tau txais cov ntaub ntawv tiav thiab txhim khu kev qha?
