Diagnostic Nzira yeUltrasonography

Ultrasound inyanzvi yezvokurapa yemhando yepamusoro, iyo yave iri nzira inowanzoshandiswa yekuongorora nachiremba vane nzira yakanaka.Ultrasound yakakamurwa kuva A mhando (oscilloscopic) nzira, B mhando (imaging) nzira, M mhando (echocardiography) nzira, fan fan (two-dimensional echocardiography) nzira, Doppler ultrasonic nzira uye zvichingodaro.Muchokwadi, nzira yemhando yeB yakakamurwa kuita zvikamu zvitatu: kutsvaira kwemutsara, kutsvaira kwefeni uye kutsvaira kwearc, kureva kuti, nzira yemhando yefan inofanirwa kuverengerwa mumhando yeB nzira.

A type method

Nzira yemhando yeA ndiyo inonyanya kushandiswa kuona kana kune maronda asina kujairika kubva paamplitude, nhamba yemasaisai, uye kutevedzana kwemasaisai pane oscilloscope.Iyo inovimbika zvakanyanya mukuongororwa kwecerebral hematoma, mabundu ehuropi, cysts, mazamu edema uye kuzvimba kwedumbu, nhumbu yekutanga, hydatidiform mole uye zvimwe zvinhu.

B mhando nzira

Nzira yeB-mhando ndiyo inonyanya kushandiswa uye inogona kuwana zvakasiyana-siyana zvemukati-sectional maitiro enhengo dzemukati dzevanhu, yakave yakanyatsoshanda mukuongororwa kwehuropi, mboni yeziso (semuenzaniso, retinal detachment) uye orbit, thyroid, chiropa (zvakadai. sekuonekwa kwekenza diki yechiropa isingasviki 1.5 masendimita muhupamhi), gallbladder uye biliary, pancreas, spleen, obstetrics, gynecology, urology (itsvo, dundira, prostate, scrotum), kuzivikanwa kwemuviri wedumbu, intra-abdominal hombe yemidziyo yeropa zvirwere ( senge abdominal aortic aneurysms, inferior vena cava thrombosis), mitsipa nemakumbo hombe dzetsinga dzeropa.Iwo magirafu ane intuitive uye akajeka, zvichiita kuti zvive nyore kuona maronda madiki.Dzidza zvakawanda nezveUltrasound muchina

M mhando nzira

Iyo M mhando nzira ndeyekunyora echo chinhambwe chekuchinja curve pakati payo nemadziro echipfuva (probe) zvinoenderana nemabasa emoyo uye zvimwe zvimiro mumuviri.Uye kubva pane iyi curve chati, madziro emoyo, interventricular septum, moyo mhango, vharafu uye zvimwe zvinhu zvinogona kunyatsozivikanwa.ECG uye mwoyo inzwi mepu kuratidza zvinyorwa zvinowanzowedzerwa panguva imwe chete kuti uongorore zvirwere zvakasiyana-siyana zvemwoyo.Kune zvimwe zvirwere, zvakadai seatrial myxoma, nzira iyi ine mwero wepamusoro wekuteerera.
