Nzira yeDoppler inobva pakuongorora masvingo emidziyo yeropa uchishandisa ultrasound, ultrasound inoratidzwa kubva kune masero matsvuku eropa uye inoita kuti zvikwanise kuongororangisa kunyange zvirwere zviduku zvikuru uye mitsipa. Transcranial dopplerography inosanganisira kuongorora kwekushandiswa kwemakumbo nekubatsirwa nenzira iyi uye ndeimwe yenzira dzakaderera, dzinodzidzisa uye dzinokurumidza yekugadzirisa kuongororwa.
Chii chicharatidza kutengesa dopplerography yemidziyo yekuberekwa?
Transcranial dopplerography yemidziyo yemusoro inoita kuti zvikwanise kutsvaga mavara ekutsvaga:
- kureba kwemidziyo yeropa huru;
- rusvingo ukuru;
- ropa flow rate;
- chiyero chemafupa;
- zvakasiyana-siyana zvinopesana nezvinhu - nekusimudzira kufamba, rusvingo rworusvingo;
- atherosclerosis uye chiyero chekuregererwa kwaro;
- chikamu uye chimiro chekuyerera kweropa;
- kuenzanisa kweropa kunobva kumativi akasiyana emuusoro;
- systolic speed;
- degree of stenosis .
Zvakakosha kuziva kuti muchidzidzo, chigadziro chekuita dopplerography chinoratidza kushambadzira pamwe chete, asi masangano makuru uye mitsetse. Zvikepe zviduku zveuropi hazvikwanisi kudzidziswa nekuda kwehupamhi hukuru hwemasvingo ehenya. Aya ma sensor akaiswa munzvimbo dzakanakisa - pamusoro pemashizha, pamatemberi uye pasi pechikamu chechipipital chemusoro.
Chikonzero chekuenderera mberi kwechirongwa che ultrasonic dopplerography zvinhu zvakadai:
- kugara mucheche uye musoro;
- kurohwa , kurwadziwa kwemwoyo, thrombosis yakawedzerwa;
- kurasikirwa kweimwe kutaura mutauro;
- kuonekwa kwemapofu maziso uye kutadza kuona;
- kurasikirwa kwekunzwa, kunhuwa uye kuonekwa kwakakwana kwehutano hunhu hwezvibereko;
- kuvhiringidzwa kwemangariro nemafungiro;
- kurasikirwa kwekutungamira kukwanisa munzvimbo uye nezvimwe zvakawanda.
Izvozvo zvinotapira sei ultrasound Doppler?
Nzira yekufambisa dopplerography, kana tkdg, sezvainowanzoidzwa nevashandi vezvokurapa, iri nyore: murwere achakumbirwa kurara pasi, mwana wevana mwana achagara pamutsipa wake uye oisa masvikiro echigadzirwa munzvimbo dzakakodzera. Penguva yekuongorora, chipisa chichave chakafukidzwa nejeri chaiyo uye zvishoma nezvishoma zvichaongorora midziyo. Nokuti chimwe nechimwe chazvo chine maitiro ake chaiwo, chinofanirwa kuiswa, chakanyorwa uye chakaongororwa nechinowanzoenderana nenzvimbo imwe neimwe yeuropi. Kazhinji, ruzivo rwose haruna kuendeswa kune neurologist, mwana wenyanzvi anongorongedza chete iyo dhesi iyo inopfuura kudarika. Pakati pevhesi, nzira yacho inotora kubva pamaminitsi makumi matatu kusvika paawa.
