Cardiac Doppler ultrasound inzira inoshanda zvikuru yekuongorora chirwere chemwoyo, kunyanya chirwere chemwoyo chekuzvarwa nacho. Kubva kuma1980, tekinoroji yekuongorora ultrasound yakatanga kukura nekukurumidza kunoshamisa. Kufanana nemagnetic resonance imaging, CT uye isotope scanning, cardiac Doppler ultrasound inewo nzvimbo mune mana makuru ekuongorora mifananidzo mukurapa kwemazuva ano.
Kuongororwa kweDoppler yemwoyo ndeimwe yenzira dzakakosha dzekuongorora mifananidzo mukuongorora kwemwoyo kusingakuvadzi. Iyi tekinoroji yekuongorora haina chete zvakanakira zvekusarwadziwa, kudzokororwa, kusingakuvadzi uye kuri nyore, asiwo ine mhedzisiro yekuongorora yakajeka uye yakarurama kupfuura mimwe ongororo yemifananidzo. Mushure memakore akati wandei ekusimudzira, ultrasound yeDoppler yemwoyo yave chishandiso chakakosha chekuongorora mukurapa kwemazuva ano.
Kazhinji, kana mhedzisiro yekuonekwa kwechirwere ichi iri kushomeka kudiki, hapana kurapwa kwakakosha kunodiwa. Kana chiri kutadza kwemoyo kuri pakati nepakati kana kwakanyanya, kurapwa kunofanirwa kuitwa nekukurumidza kudzivirira shanduko muchimiro chemwoyo wemurwere uye mukana wekuti pave nematambudziko akakomba. Mukuongororwa kwecardiomyopathy, cardiac Doppler ultrasound inogona kuona huwandu hwemyocardial hypertrophy uye kukura kwekamuri remwoyo muvarwere; kune varwere vane chirwere chemwoyo, cardiac Doppler ultrasound inogona kuratidza nzvimbo ye myocardial ischemia, zvichibatsira vanachiremba kugadzira hurongwa hwakakodzera hwekurapa zvichienderana nemamiriro chaiwo evarwere. Zvirwere zvikuru zvinoonekwa necardiac Doppler ultrasound zvinosanganisira kukuvara kweaortic (senge kukuvara kwakadai seaortic stenosis), zvirwere zvevharuvhu yemoyo (senge mitral valve lesions, stenosis, nezvimwewo), zvirwere zve ventricular, nezvimwewo.
Cardiac Doppler ultrasound haingogone kuratidza kupararira kweropa risingawanzoitika mumoyo, asiwo inoratidza nzira uye gwara rekuyerera kweropa remwoyo kusvika pamwero wakati. Inogona kuona kana rudzi rwekuyerera kweropa remwoyo rwuri rwe laminar flow, turbulent flow kana eddy flow, uye inogonawo kuyera contour, nzvimbo, kureba uye upamhi hwakati hwe blood flow beam. Cardiac Doppler ultrasound inogona kuratidza zvakananga hukama huripo pakati pechimiro chemwoyo chisina kujairika uye cardiac hemodynamics isina kujairika nekuratidza ruzivo rwekuyerera kweropa mu diagram ine mativi maviri. Vana vese vanofungidzirwa kuti vane chirwere chemwoyo chekuzvarwa nacho vanofanira kuongororwa cardiac Doppler ultrasound kuti vaone kukura kwechirwere chacho.
Kuongororwa kwe ultrasound ye cardiac Doppler kuongororwa kwakakosha zvikuru, kunyanya kune varwere vane chirwere chemwoyo cheorganic. Kuburikidza ne cardiac Doppler color ultrasound, zvinokwanisika kuona kana mwoyo wemunhu wacho uine matambudziko emuumbirwo, kana vharuvhu yemoyo ine miti kana zvimwe zvinetso. Inzvimbo yakavimbikawo yekuongorora mashandiro emwoyo wemurwere, kuongorora chirwere che pericardial, uye kuona mashandiro evharuvhu.
Kuongororwa kweDoppler color ultrasound yemwoyo nemutsipa wechibereko kwakaisa hwaro hwechipatara chedu kuti chishumire vanhu vari pedyo zviri nani. Yongkang Medical inogadzira michina yeDoppler color ultrasound ine mhando dzakasiyana dzemhando dzeB-ultrasound color ultrasound. Kana zvikakuomera kusarudza, Yonkermed Medical inogona kupa ruzivo rwakadzama nezvechigadzirwa chemuchina we ultrasound yemavara uye kubatsira kukurudzira zvigadzirwa zvakati wandei zvakakodzera. Zvinogonawo kukutora kuti uzvionere wega, kuitira kuti ugone kutenga uine chivimbo.
At Yonkermed, tinodada nekupa rubatsiro rwakanakisisa kune vatengi. Kana paine nyaya yaunofarira, yaunoda kudzidza zvakawanda nezvayo, kana kuverenga nezvayo, ndapota inzwa wakasununguka kutibata!
Kana muchida kuziva munyori, ndapotatinya pano
Kana muchida kutibata nesu, ndapotatinya pano
Nemwoyo wose,
