I-Doppler Color Ultrasound: Vumela Izifo zingabi nandawo yokucasha

I-Cardiac Doppler ultrasound iyindlela yokuhlola ephumelela kakhulu yokuxilongwa komtholampilo kwesifo senhliziyo, ikakhulukazi isifo senhliziyo sokuzalwa. Kusukela ngawo-1980, ubuchwepheshe bokuhlola i-ultrasound buqale ukukhula ngesivinini esimangalisayo. Njengokuthwebula kwe-resonance kazibuthe, ukuskena kwe-CT ne-isotope, i-Doppler ultrasound yenhliziyo nayo inendawo kubuchwepheshe obune bokuhlonza izithombe emithini yesimanje.
I-Cardiac Doppler ultrasound ingenye yezindlela zobuchwepheshe zokuhlola izithombe ezibaluleke kakhulu ekuhlolweni kwenhliziyo okungahlaseli. Lobu buchwepheshe bokuhlolwa abunayo nje kuphela izinzuzo zokungabi nabuhlungu, ukuphindaphindeka, ukungabi nangozi nokulula, kodwa futhi kunemiphumela yokuhlolwa ecacile nenembe kakhulu kunezinye izivivinyo zezithombe. Ngemuva kweminyaka eminingana yokukhushulwa, i-Doppler ultrasound yenhliziyo isiphenduke ithuluzi lokuxilonga elibalulekile emithini yesimanje yomtholampilo.
Ngokuvamile, uma umphumela wokutholwa kuwukuntula okuncane kuphela, akukho ukwelashwa okukhethekile okudingekayo. Uma ukwehluleka kwenhliziyo okulinganiselwe noma okunzima, ukwelashwa kufanele kwenziwe ngokushesha ngangokunokwenzeka ukuze kuvinjelwe izinguquko esakhiweni senhliziyo yesiguli kanye nokwenzeka kwezinkinga ezinkulu. Ekuhlolweni kwe-cardiomyopathy, i-Doppler ultrasound yenhliziyo inganquma izinga le-myocardial hypertrophy kanye nokwandiswa kwegumbi lenhliziyo ezigulini; ezigulini ezinesifo senhliziyo, i-Doppler ultrasound yenhliziyo ingabonisa ngokunembile indawo ye-myocardial ischemia, isiza odokotela ukuba bathuthukise izinhlelo zokwelashwa ezifanele ngokuvumelana nezimo ezithile zeziguli. Izifo eziyinhloko ezitholwe yi-cardiac Doppler ultrasound zifaka izilonda ze-aortic (njengezilonda ezifana ne-aortic stenosis), izifo ze-valve yenhliziyo (njengezilonda ze-mitral valve, i-stenosis, njll.), izifo ze-ventricular, njll.
I-Cardiac Doppler ultrasound ayikwazi nje ukukhombisa ukusatshalaliswa kokugeleza kwegazi okungavamile emgodini wenhliziyo, kodwa futhi ibonise indlela kanye nesiqondiso sokugeleza kwegazi lenhliziyo ngezinga elithile. Ingakwazi ukunquma ukuthi imvelo yokugeleza kwegazi lenhliziyo iwukugeleza kwe-laminar, ukugeleza kwesiphithiphithi noma ukugeleza kwe-eddy, futhi ingaphinda ilinganise i-contour, indawo, ubude kanye nobubanzi obuthile bomugqa wokugeleza kwegazi. I-Cardiac Doppler ultrasound ingabonisa ngokuqondile ubudlelwano phakathi kwesakhiwo senhliziyo esingavamile kanye ne-hemodynamics yenhliziyo engavamile ngokubonisa ulwazi lokugeleza kwegazi kumdwebo we-cross-sectional onezinhlangothi ezimbili. Zonke izingane okusolakala ukuthi zinesifo senhliziyo ezizalwa nazo kumele zihlolwe yinhliziyo ye-Doppler ultrasound ukuze kutholakale ukukhula okuqondile kwalesi sifo.

Ukuhlolwa kwe-Cardiac Doppler ultrasound ukuhlolwa okubaluleke kakhulu, ikakhulukazi ezigulini ezinesifo senhliziyo esiphilayo. Nge-ultrasound yenhliziyo ye-Doppler color ultrasound, kuyenzeka ukuthi kutholakale ukuthi inhliziyo yalowo othintekayo inokungalungi kwesakhiwo, noma ngabe ivalvu yenhliziyo inohlaza noma ezinye izinkinga. Futhi iyinkomba enokwethenjelwa kakhulu yokuhlola ukusebenza kwenhliziyo yesiguli, ukuhlola isifo se-pericardial, kanye nokubona ukusebenza kwe-valve.
Ukuhlolwa kwe-Doppler color ultrasound yenhliziyo nemithambo yomlomo wesibeletho kuye kwabeka isisekelo sokuthi isibhedlela sethu sisize kangcono abantu abasizungezile. I-Yongkang Medical ingumkhiqizi womshini we-Doppler color ultrasound onezinhlobonhlobo zamamodeli emshini we-ultrasound wombala we-B-ultrasound. Uma ukuthola kunzima ukukhetha, i-Yonkermed Medical ingahlinzeka ngolwazi oluningiliziwe lomshini womshini we-ultrasound futhi isize ukuncoma imikhiqizo embalwa efanelekile. Kungase futhi kukuthathe ukuthi uzizwele ukuhlinzwa mathupha, ukuze ukwazi ukuthenga ngokuzethemba.

At Yonkermed, siyaziqhenya ngokunikeza isevisi yamakhasimende engcono kakhulu. Uma kunesihloko esithile onentshisekelo kuso, ongathanda ukufunda kabanzi ngaso, noma ukufunda ngaso, sicela ukhululeke ukusithinta!
