Doppler Ibara Ultrasound: Reka Indwara zitagira aho zihisha

Ultrasound ya Cardiac Doppler ni uburyo bwiza bwo gusuzuma bwo gusuzuma indwara z'umutima, cyane cyane indwara z'umutima. Kuva mu myaka ya za 1980, tekinoroji yo gusuzuma ultrasound yatangiye gutera imbere ku muvuduko utangaje. Kimwe na magnetic resonance imaging, CT na isotope scanning, ultrasound yumutima Doppler nayo ifite umwanya muburyo bune bukomeye bwo gupima amashusho mubuvuzi bwa kijyambere.
Ultrasound ya Cardiac Doppler nimwe mubintu byingenzi byifashishwa mu gusuzuma amashusho mu bizamini byumutima bidatera. Ubu buhanga bwikizamini ntabwo bufite ibyiza byo kutababara, gusubirwamo, kutagira ingaruka kandi byoroshye, ariko kandi bufite ibisubizo bisobanutse neza kandi byukuri kuruta ibindi bizamini byerekana amashusho. Nyuma yimyaka myinshi yo kuzamurwa, ultrasound yumutima Doppler yabaye igikoresho cyingenzi cyo gusuzuma mubuvuzi bwa kijyambere.
Muri rusange, niba ibisubizo byerekana ari kubura byoroheje, nta buvuzi bwihariye busabwa. Niba ari kunanirwa cyangwa gukabije k'umutima, kuvura bigomba gukorwa vuba bishoboka kugirango hirindwe impinduka mumiterere yumutima wumurwayi kandi hashobora kubaho ibibazo bikomeye. Mu isuzuma ry'umutima, umutima Doppler ultrasound irashobora kumenya urugero rwa hypertrophyie ya myocardial hamwe no kwaguka k'umutima ku barwayi; kubarwayi barwaye umutima wumutima, ultrasound yumutima Doppler irashobora kwerekana byimazeyo aho ischemia ya myocardial iherereye, ifasha abaganga gutegura gahunda zokuvura bakurikije imiterere yihariye yabarwayi. Indwara nyamukuru zapimwe na ultrasound yumutima Doppler zirimo ibikomere bya Aortic (nka lesion nka aortic stenosis), indwara zifata umutima (nka mitral valve lesion, stenosis, nibindi), indwara zifata amashanyarazi, nibindi.
Ultrasound ya Cardiac Doppler ntishobora kwerekana gusa ikwirakwizwa ryamaraso adasanzwe mumyanya yumutima, ariko kandi irerekana inzira nicyerekezo cyamaraso yumutima kumutima kurwego runaka. Irashobora kumenya niba imiterere yamaraso yumutima ari umuvuduko wa laminari, imivurungano cyangwa umuvuduko wa eddy, kandi irashobora no gupima imiterere, agace, uburebure nubugari bwihariye bwamaraso. Ultrasound ya Cardiac Doppler irashobora kwerekana mu buryo butaziguye isano iri hagati yimiterere yumutima idasanzwe hamwe na hemodinamike yumutima idasanzwe yerekana amakuru atembera mumaraso mubishushanyo mbonera byombi. Abana bose bakekwaho kuba barwaye indwara z'umutima bavukanye bagomba kwisuzumisha umutima Doppler ultrasound kugirango bamenye iterambere ryihariye ryindwara.
