amashusho ya ultrasound n'amabara Doppler ultrasound imashusho?
Hashize imyaka igera kuri 20, abapayiniya bamwe bariyemeje gushyiraho uburyo bwo guhugura ultrasound y’amahanga, cyane cyane abo muri Amerika, babonye icyiciro cy’ibibazo by’ibizamini by’akazi bya Amerika y'Amajyaruguru binyuze mu nzira zitandukanye.Ikibazo kimwe kigufi cyibibazo cyabajijwe: Ni irihe tandukaniro riri hagati y'amabaraULTRASONOGRAPHYNA DOPPLER ULTRASONOGRAPHY?
Ni irihe tandukaniro riri hagati yo gufata amashusho ya ultrasound n'amashusho ya Doppler ultrasound?
Amashusho ya Doppler ultrasound akimara kwinjira mu Bushinwa, yiswe "ultrasound".Abaganga ba ultrasoundi b'Abashinwa bahoraga bagereranya ultrasound y'amabara na ultrasound ya Doppler, bityo Ubushinwa bubona iki kibazo bwa mbere.Abaganga basaga naho bari mu rujijo kandi ntibazi icyo ikibazo kibaza.
Mubyukuri, iki nikibazo cyoroshye cyane.
Ibara rya ultrasound bivuga kwerekana ikimenyetso cyihariye cyamakuru ya echo mugihe cyo gusuzuma ultrasound hamwe namategeko yihariye yo kubara amabara, ariryo shusho yamabara ultrasound.Aya makuru yihariye ya echo arashobora kuba echo ubukana, Doppler frequency shift, amakuru akomeye, amakuru ya microbubble, nibindi.
bityo.Amashusho ya Doppler yerekana amashusho nimwe gusa muburyo bwinshi bwo gufata amashusho.Ikuramo amakuru ya Doppler yumurongo uhinduranya amakuru kuri echo yamakuru kandi ikayerekana muburyo bwamabara.
Usibye ibara rya Doppler yerekana ko tumenyereye, reka turebe ibara rya ultrasound yerekana amashusho.
Turabizi ko ibice bibiri-byerekana imvi-nini ya ultrasound yerekana ubukana bwikimenyetso cya echo muburyo bwo kumurika kodegisi.Niba duhinduye ibara-kode ahantu runaka cyangwa byose bimurika, tuzabona ibara-code.
Hejuru ku ifoto: Agace runaka mu kimenyetso cyerekana ibara ryanditseho ibara ry'umuyugubwe (umwambi ufunguye), kandi igikomere gifite umucyo uhuye gihinduka ibara ry'umuyugubwe (ryerekanwa n'umwambi ukomeye).
Uburyo bwo gufata amashusho yavuzwe haruguru bukubiyemo echo ubukana bwamabara cyangwa urwego rwamabara atandukanye rwamamaye cyane mubushinwa mugihe runaka muntangiriro ya 1990.Yiswe "2Dibara ry'ibaraamashusho "muri kiriya gihe. Nubwo impapuro nyinshi zasohotse muri kiriya gihe, mubyukuri agaciro ko gusaba ni gake cyane. Muri icyo gihe, ibitaro byinshi byanakoresheje iyi shusho kugira ngo bibe nk'ibara rya Doppler ryerekana kwishyuza abarwayi" amafaranga ya ultrasound ". Ntabwo byari biteye isoni.
Mubyukuri, ibimenyetso byose byamabara kumashusho ya ultrasound yerekana amashusho ni pseudo-amabara, kandi ibyo bimenyetso byamabara byakozwe muburyo bwa artificiel kandi byashyizweho natwe.
Ababikora benshiultrasonic elastography, kuri ubu ikunzwe cyane, yerekana kandi ubukana (cyangwa modulus ya elastique) ya tissue cyangwa ibikomere muburyo bwanditseho amabara, kubwibyo rero ni ubwoko bwamabara ultrasound.
Hejuru ku ifoto: Shear wave elastography yerekana modulike ya elastike ya lesion mubipimo by'amabara.
Iyo mikorobe ntoya iturika, hazakorwa ingaruka zikomeye zidafite umurongo, akenshi zidafitanye isano neza nimbaraga za echo.Twise ubu buryo bwo gukuramo amakuru adafitanye isano no gufata amashusho adafitanye isano.Amashusho adafitanye isano akoreshwa cyane cyane kugirango yerekane bike cyane bya mikorobe kandi ni ingirakamaro cyane mubushakashatsi bwakozwe na ultrasound.Mubisanzwe, uku kudahuza nabyo kugaragara muburyo bwamabara, bityo rero ni amashusho yerekana amabara.
Hejuru ku ifoto: p-hitamo microbubble-igamije kwerekana amashusho yerekana uburyo bwo kuzamura urukuta rwimbere nyuma ya ischemia, hamwe na myocardial itandukaniro-yongerewe imbaraga ya sonografi yumutima muto-axis amashusho mumbere yimbere imanuka ischemia-reperfusion mumbeba.
(A) Myocardial itandukaniro-yongerewe imbaraga ultrasound yerekana inenge yimbere (umwambi) mugihe cya ischemia myocardial.
(B) Nyuma yiminota 45 yo kwisubiraho.Igipimo cyamabara cyerekana ubukana bwamashusho adafitanye isano na microbubbles.
Amashusho yerekana amaraso yerekana amashusho hepfo nuburyo bwo gufata amashusho ultrasound
