Dab tsi yog qhov sib piv-hloov ultrasound
Nov 24, 2022
Contrast-enhanced ultrasound (CEUS) yog ib txoj hauv kev ntawm cov duab nrog tus neeg saib xyuas qhov sib txawv ntawm ultrasound. Ultrasonic contrast tus neeg sawv cev yog cov kua npuas nrog ib txoj kab uas hla ntawm ob peb microns. Los ntawm kev siv cov npuas dej uas muaj zog dispersing zog rau ultrasound, tus neeg saib xyuas qhov sib txawv ultrasonic yog kho rau hauv tib neeg cov hlab ntsha los txhim kho lub ultrasonic Doppler teeb liab ntawm cov ntshav khiav, txhim kho qhov pom tseeb thiab kev daws teeb meem ntawm cov duab ultrasound, txhim kho cov suab paj nruag intravascular, thiab ua kom pom cov duab zoo dua. microcirculation ntshav perfusion.
Ceus tuaj yeem txhim kho ob lub ntsej muag ultrasound duab thiab cov ntshav ntws Doppler teeb liab ntawm txhua lub hauv nruab nrog cev, suav nrog myocardium, plab hnyuv, hlwb thiab lwm yam kabmob, thiab xav txog thiab saib xyuas cov ntshav perfusion ntawm cov ntaub so ntswg thiab cov kab mob.
Ceus tuaj yeem paub qhov txawv ntawm cov ntshav doppler cov cim hauv parenchymal hauv nruab nrog cev, thiab zoo dua nrhiav pom cov qauv txawv txav, suav nrog cov ntshav perfusion hauv qhov txhab, uas yog ib txoj hauv kev zoo heev.
