sawirka ultrasound iyo midabka Doppler ultrasound imaging?
Qiyaastii 20 sano ka hor, qaar ka mid ah hormuudka u heellan inay soo bandhigaan hababka tababarka ultrasound ee ajnabiga ah, gaar ahaan kuwa ka yimid Maraykanka, ayaa helay dufcad ka mid ah su'aalaha baaritaanka shaqada ee ultrasound ee Waqooyiga Ameerika iyada oo loo marayo waddooyin kala duwan.Hal su'aal jawaab gaaban ayaa la weydiiyay: Waa maxay faraqa u dhexeeya MIDABKAultrasographyiyo MIDABKA DOPPLER ultrasonography?
Waa maxay farqiga u dhexeeya sawirka ultrasound midabka iyo midabka Doppler ultrasound imaging?
Isla markii midabka Doppler ultrasound imaging soo galay Shiinaha, waxaa loo tixraacay "ultrasound midabka".Dhakhaatiirta Shiinuhu waxay had iyo jeer barbar dhigaan ultrasound midabka midabka Doppler ultrasound, sidaas darteed Shiinuhu wuxuu arkay dhibaatadan markii ugu horeysay.Dhakhaatiirtu waxay u muuqdeen kuwo wareersan oo garan la' waxa su'aasha la weydiinayo.
Dhab ahaantii, tani waa su'aal aad u fudud.
Ultrasound Midabka waxaa loola jeedaa muujinta calaamad gaar ah oo ah macluumaadka dhawaaqa inta lagu jiro baaritaanka ultrasound ee leh shuruuc midab gaar ah, kaas oo ah sawirka ultrasound midabka.Macluumaadkan echo ee gaarka ah waxay noqon karaan xoojinta dhawaaqa, isbeddelka soo noqnoqda ee Doppler, macluumaadka adkaanta, macluumaadka microbubble, iwm.
sidaas.Midabka Doppler imaging waa mid ka mid ah hababka sawirka midabka badan.Waxay ka soo saartaa macluumaadka isbeddelka soo noqnoqda ee Doppler ee macluumaadka echo waxayna u soo bandhigtaa qaab kood midab leh.
Marka laga soo tago midabka Doppler imaging ee aynu naqaan, aynu eegno midabka ultrasound imaging hababka.
Waxaan ognahay in ultrasound-ka-cawlan ee laba-geesoodka ah uu muujiyo xoogga signalka dhawaaqa ee qaabka codaynta dhalaalka.Haddii aan midab-codee meel gaar ah ama dhammaan dhalaalka, waxaan heli doonaa sawir midab leh.
Xagga sare: Meel gaar ah oo ku taal calaamadda cawl waxa lagu calaamadeeyay guduud (falaar furan), nabarka leh dhalaal u dhigma wuxuu isu beddelaa guduud (oo lagu muujiyey fallaadho adag).
Habka sawir-qaadista ee kor ku xusan ee qeexaya xoojinta midabka ama midabada kala duwan ayaa aad caan uga ahaa Shiinaha in muddo ah horraantii 1990-meeyadii.Waxaa loo yaqaan "2Dmidab been abuur ahimaging "waqtigaas. Inkasta oo waraaqo badan la daabacay wakhtigaas, dhab ahaantii Qiimaha codsigu aad ayuu u xaddidan yahay. Waqtigaas, isbitaallo badan ayaa xitaa isticmaalay sawirkan si ay u dhaafaan midabka Doppler imaging si ay u dalacaan bukaannada "qiimaha ultrasound midabka". Runtii ceeb bay ahayd.
Dhab ahaantii, dhammaan calaamadaha midabka ee sawirka ultrasound midabka waa midabyo been abuur ah, iyo calaamadahan midabada si macmal ah ayaa loo habeeyey oo anaga ayaa dejinay.
Inta badan soo saarayaashaelastography ultrasonic, kaas oo hadda aad loo jecel yahay, sidoo kale wuxuu muujiyaa adkaanta (ama modules laastikada) ee nudaha ama dhaawacyada qaab midab leh, sidaas darteed sidoo kale waa nooc ka mid ah ultrasound midabka.
Xagga sare: Sawir-qaadista mawjada xiirid waxay ku tusaysaa moodeelka laastikada ee nabarka ee cabbirka midabka.
Marka qadar yar oo microbubbles ah ay qarxaan, saameyn xoog leh oo aan toos ahayn ayaa la soo saari doonaa, taas oo inta badan aan si qumman ula xiriirin xoojinta dhawaaqa.Waxaanu ugu yeedhnaa qaabkan soo saarista macluumaadka aan xidhiidhsanayn ee sawirida sawirida aan xidhiidhsanayn.Sawirka aan isku xidhnayn ayaa inta badan loo isticmaalaa in lagu soo bandhigo xaddi aad u yar oo ah xumbo-yaro waxayna aad faa'iido ugu leedahay cilmi-baadhista ultrasound-ka ee la beegsado microbubble.Caadi ahaan, xidhiidh la'aantan ayaa sidoo kale lagu soo bandhigay qaab midab leh, sidaas darteed sidoo kale waa sawir midab leh.
Xagga sare: sawirka p-selectin microbubble-bartilmaameedku wuxuu muujinayaa wanaajinta xulashada darbiga hore ee ischemia ka dib, iyo myocardial-ka-soo-jeedka isbarbardhigga muuqaalada dhidibada gaaban ee wadnaha ee xagga hore ee bidix ee soo degaya ischemia-kabashada jiirarka.
(A) Ultrasound-ka-soo-baxsan ee ka-duwanaanta myokardiyaha ayaa muujinaya cillad hore oo falaarta ah inta lagu jiro ischemia myocardial.
(B) Ka dib 45 daqiiqo oo dib u soo celin ah.Miisaanka midabku wuxuu u taagan yahay xoojinta sawirka aan la xiriirin ee microbubbles la beegsaday.
Sawirka xididka qulqulka dhiigga ee hoose sidoo kale waa qaabka sawirka ultrasound midabka
