Doppler Colour Ultrasound: Rega Chirwere chishaye pekuhwanda

Cardiac Doppler ultrasound inzira inoshanda kwazvo yekuongorora yekiriniki yekuongororwa kwechirwere chemoyo, kunyanya congenital moyo chirwere. Kubva kuma1980, tekinoroji yekuongorora ultrasound yakatanga kukura nekumhanya kunoshamisa. Kufanana nemagineti resonance imaging, CT uye isotope scanning, cardiac Doppler ultrasound inewo nzvimbo mune ina huru yekufungidzira tekinoroji yekuongorora mukurapa kwemazuva ano.
Cardiac Doppler ultrasound ndeimwe yeakanyanya kukosha ekufungidzira tekinoroji mukuongororwa kusingapindike kwemoyo. Iyi tekinoroji yebvunzo haina chete zvakanakira kusarwadza, kudzokororwa, kusakuvadza uye nyore, asi zvakare ine yakajeka uye yakanyatsojeka mhinduro dzebvunzo pane dzimwe bvunzo dzekufungidzira. Mushure memakore akati wandei ekusimudzirwa, yemoyo Doppler ultrasound yave chinhu chakakosha chekuongorora mumishonga yemazuva ano yekiriniki.
Kazhinji kutaura, kana mhedzisiro yekuona ichingove kushomeka kwakapfava, hapana kurapa kwakakosha kunodiwa. Kana iine mwero kana yakanyanya kukundikana kwemoyo, kurapwa kunofanira kuitwa nekukurumidza sezvinobvira kudzivirira shanduko muchimiro chemoyo wemurwere uye mukana wematambudziko akakomba. Mukuongorora kwe cardiomyopathy, cardiac Doppler ultrasound inogona kuona chiyero chemyocardial hypertrophy uye kuwedzera kwekamuri yemwoyo muvarwere; kune varwere vane chirwere chemwoyo, cardiac Doppler ultrasound inogona kuratidza intuitively nzvimbo yemyocardial ischemia, kubatsira vanachiremba kuti vagadzire zvirongwa zvekurapa zvakakodzera maererano nemamiriro chaiwo evarwere. Zvirwere zvikuru zvakaonekwa ne cardiac Doppler ultrasound zvinosanganisira aortic maronda (akadai semaronda akadai seaortic stenosis), zvirwere zvemwoyo valve (zvakadai semitral valve lesions, stenosis, nezvimwewo), zvirwere zve ventricular, nezvimwewo.
Cardiac Doppler ultrasound haigoni kuratidza kuparadzirwa kweropa risina kujairika mumhango yemwoyo, asiwo kuratidza nzira uye nzira yekuyerera kweropa kune imwe nzvimbo. Inogona kuona kana chimiro chemoyo wekuyerera kweropa kuyerera kwelaminar, mhirizhonga kuyerera kana eddy kuyerera, uye inogona zvakare kuyera contour, nzvimbo, kureba uye chaiyo hupamhi hwekuyerera kweropa. Cardiac Doppler ultrasound inogona kuratidza zvakananga hukama pakati pemaitiro asina kujairika emwoyo uye abnormal cardiac hemodynamics nekuratidza kuyerera kweropa ruzivo mune maviri-dimensional cross-sectional diagram. Vese vana vanofungidzirwa kuti vane chirwere chemoyo chekuzvarwa vanofanira kuongororwa nemoyo weDoppler ultrasound kuti vaone kukura kwechirwere.
