Yintoni iDoppler Imaging?

I-Ultrasound Doppler imaging kukukwazi ukuvavanya nokulinganisa ukuhamba kwegazi kwimithambo eyahlukeneyo, kwimithambo yegazi, nakwimithambo yegazi. Idla ngokumelwa ngumfanekiso oshukumayo kwiscreen senkqubo ye-ultrasound, umntu unokuchonga uvavanyo lweDoppler ukusuka ekuhambeni kwegazi okunemibala okubonakalayo kumfanekiso we-ultrasound. I-Doppler inokutolika imibala kumfanekiso ngokusekelwe ekulinganiseni ukuhamba kwegazi kwindawo ethile eboniswayo.

I-Doppler imaging yahlukile kwi-ultrasound yendabuko ngendlela enye esisiseko: ayibonisi sakhiwo nasiphi na. I-ultrasound yendabuko inika imifanekiso yezakhiwo ezahlukeneyo, amalungu omzimba, kunye nemithambo yegazi ukuze kuchongwe ukukhula, ukuqhekeka, iingxaki zesakhiwo, kunye nezinye iimeko ezininzi ezinokubakho. I-Doppler imaging, kwelinye icala, ibonisa kuphela umfanekiso wokuhamba kwegazi.

I-Ultrasound Doppler imaging yindlela eyaziwayo nehlonitshwayo kwihlabathi liphela ngenxa yokuba ayingenisi ntsholongwane kwaye ayinayo i-radioactive. I-Doppler ayisebenzisi i-radiation okanye iimpawu zokungena, kodwa isebenza ngendlela efanayo nezinye izixhobo ze-ultrasound imaging; isebenzisa amaza esandi aphezulu abonakaliswayo kwaye aguqulwa abe yimibala, imifanekiso, kunye neentshukumo ezahlukeneyo.

Iinkonzo zeDoppler Imaging:

I-Doppler imaging yahlukile kwi-ultrasound yendabuko ngendlela enye esisiseko: ayibonisi sakhiwo nasiphi na isakhiwo. I-ultrasound yendabuko inika imifanekiso yezakhiwo ezahlukeneyo, amalungu, kunye nemithambo ukuze kuchongwe ukukhula, ukuqhekeka, iingxaki zesakhiwo, kunye nezinye iimeko ezininzi ezinokubakho.

Kwelinye icala, i-Doppler imaging isetyenziselwa ukubona ukuhamba kwegazi kunye neengozi ezahlukeneyo ezinokubakho kwimithambo yegazi, kwimithambo yegazi, nakwimithambo yegazi. I-Doppler imaging idla ngokusetyenziselwa ukubona amahlwili egazi, ukuchonga iivalvu ezingasebenzi kakuhle kwimithambo yegazi, ukufumanisa ukuba imithambo yegazi ivaliwe na, okanye ukuchonga ukujikeleza kwegazi okunciphileyo emzimbeni wonke. Zonke ezi ngozi zinokubakho kwimpilo nakubomi zinokubonwa kwaye zithintelwe nge-Doppler imaging.

Abantu basebenzisa i-Doppler imaging kwiindlela ezahlukeneyo zokusebenza: Umzekelo, i-cardiac Doppler, ejonga ukuhamba kwegazi ukuya nokubuya entliziyweni, yinxalenye eqhelekileyo nebaluleke kakhulu yovavanyo lwesifo sentliziyo.

Ezinye iindlela ezidumileyo zokusebenzisa iDoppler ziquka i-transcranial Doppler (ukulandelela ukuhamba kwegazi ngengqondo nasentloko), i-vascular Doppler, kunye ne-general venous and arterial Doppler.
