Txoj kev Doppler yog raws li txoj kev tshawb ntawm phab ntsa ntawm cov hlab ntsha uas siv ultrasound, ultrasound yog reflected ntawm cov ntshav liab thiab ua rau nws ua tau los soj ntsuam me me thiab cov leeg thiab cov leeg. Transcranial dopplerography npog txoj kev tshawb fawb ntawm paj hlwb nrog kev pab los ntawm hom no thiab yog ib qho ntawm qhov pheej yig tshaj, kev tshaj tawm thiab sai tshaj plaws ntawm kev tsim kom muaj tus mob.
Dab tsi yuav ua rau pom cov hlab ntsha ntawm transgranial cerebral vessels?
Transcranial dopplerography ntawm cov hlab ntsha ntawm lub taub hau ua rau nws tau txais cov kab hauv qab no:
- qhov ntsuas ntawm cov hlab ntsha loj;
- phab ntsa thickness;
- ntshav txaus npaum li cas;
- nyiaj ntawm cov kis ntawm cov ntshav;
- ntau yam tsis haum - nrog kev ua suab paj nruag, phab ntsa roughness;
- atherosclerosis thiab cov neeg kawm ntawv qib siab ntawm qhov tsis saib xyuas;
- theem thiab qhov ntawm ntshav khiav;
- symmetry ntawm ntshav khiav ntawm ntau sab ntawm lub taub hau;
- systolic ceev;
- degree ntawm stenosis .
Nws yog tsim nyog sau cia tias nyob hauv txoj kev tshawb no, lub cuab yeej ua rau dopplerography ua rau pom kev txav raws lub ntsiab, theej loj hlav thiab leeg. Cov hlab ntsha ntawm lub hlwb tsis tuaj yeem tshawb tau vim qhov loj tuab ntawm cov phab ntsa ntawm pob txha taub hau. Lub ntsuas yog ntsia tau rau hauv qhov chaw thinnest - saum cov tsom iav, ntawm cov tuam tsev thiab qis dua qev ntawm lub taub hau ntawm lub taub hau.
Yog vim li cas mus hauv transcultural ultrasonic dopplerography yog xws li:
- nquag kiv taub hau thiab mob taub hau;
- cwj nrag , plawv nres, mob ntxiv ntshav liab;
- poob qee yam kev hais lus;
- pom cov qhov muag tsis pom kev thiab qhov muag tsis pom kev;
- tsis hnov lus zoo, tsis hnov ntxhiab thiab pom kev zoo ntawm cov yam ntxwv ntawm cov khoom;
- tsis meej pem ntawm kev xav thiab kev xav;
- tsis muaj peev xwm hauv chaw seem thiab ntau ntxiv.
Yuav ua li cas yog transcranial ultrasound Doppler?
Tus txheej txheem ntawm transcranial dopplerography, los yog tkdg, raws li nws feem ntau hu ua los ntawm cov neeg ua hauj lwm kho mob, nws yooj yim heev: tus neeg mob yuav tsum tau kom pw, tus sonologist yuav zaum tom qab ntawm nws lub caj dab thiab txhim kho cov sensors ntawm lub cuab yeej nyob rau hauv qhov chaw. Thaum lub sij hawm qhov kev kuaj mob, lub hau yuav tau them nrog ib tus gel tshwj xeeb thiab yuav maj mam kuaj cov hlab ntsha. Rau txhua tus ntawm lawv muaj nws tus kheej cov yeeb yam, lawv yuav tsum tau ntsia, sau thiab kos nrog cov cai rau txhua cheeb tsam ntawm lub hlwb. Feem ntau, tag nrho cov ntaub ntawv tsis muab xa mus rau tus kws kho paj hlwb, cov ntaub ntawv sonologist tsuas yog cov ntaub ntawv uas dhau mus tshaj li qub. Qhov nruab nrab, txoj kev yuav siv sijhawm 30 feeb mus rau ib teev.
