Dopplerography yemidziyo ndiyo nzira yemazuva ano yekuongorora inobvumira kuongorora nzvimbo yemubhedha wemavhesi nenzira ye ultrasound. Mamwe mazita emugwagwa iyi ndeyekudzidzira kudhinda yemidziyo, ultrasound yemidziyo.
Dopplerography inopa ruzivo rwakakwana pamusoro pekugadzirwa kwemidziyo yeropa uye kuti ropa rinofamba sei mavari. Izvi zvinoita kuti zvikwanise kuona zvirwere zvakasiyana-siyana mumatanho ekutanga, kudzivirira kukura kwezvirwere zvakanyanya. Mukuwedzera kune kuongororwa, iyi nzira inoshandiswa kusarudza nzira yekurapa uye kuongorora zvayo.
Iyo nzira inoitwa pamwe nekubatsirwa kwema-ultrasound rays, iyo inoshandiswa mumutambo wekushandiswa kwezvikamu zvakasiyana-siyana. Zvisinei, munyaya iyi sensu inoshandiswa iyo inobva yatora uye inogamuchira mazai e ultrasonic, kushanda pamutemo weDoppler effect. Muchiitiko ichi, nzira yacho yakachengeteka uye haina marwadzo uye inogona kuitwa kakawanda kana zvichidikanwa.
Mhando uye zviratidzo zve dopplerography yemidziyo
Ichi chidzidzo, sekutonga, chinosarudzwa zvichienderana nemakungiriro ane chirwere uye mararamiro ehutachiona, izvo zvinoita kuti munhu afungidzire chirwere chemapfupa. Panguva yekufamba, zvichienderana nenzvimbo yemidziyo, ma sensor ane maitiro akasiyana-siyana e-ultrasound anoshandiswa. Funga nezvei zviratidzo zvinogona kugoverwa kune zvakasiyana siyana zve dopplerography.
1. Dopplerography yemidziyo yemutsipa neyo musoro:
- musoro, chizoro;
- kurasikirwa kwekuziva;
- kukanganwa kwepfungwa;
- kushushikana kwehope;
- blood pressure change;
- ruzha munzeve;
- "Nhunzi" pamberi pemaziso , nezvimwewo.
2. Ultrasonic dopplerography yemidziyo yepamusoro uye kumusoro:
- kuchena kwamaoko, tsoka;
- kuzvimba kwemaoko, tsoka;
- kunetseka, kupera kwemakumbo;
- kurwadziwa kana uchifamba;
- kurasikirwa kwesimba musimba mumaoko;
- kuchinja muhuzha rweganda remagumo, nezvimwewo.
3. Dopplerography yemidziyo yeimpimwa:
- kurwadziwa munharaunda yekomba;
- blood pressure change;
- musiyano muhukuru hwetsvo dzakasara uye dzakarurama;
- polyuria nevamwe.
Transcranial dopplerography yemidziyo yeperesi
Transcranial dopplerography yemidziyo yemakemikari inoitwa nechinangwa chekuzarura zvipembenene zvezvikepe zvisingaiti uye zvirwere zvakasiyana-siyana zvekubuda kweropa mazviri. Iyi nzira inoitwa, kunyanya, ne:
- migraines;
- vegetative vascular dystonia ;
- craniocerebral trauma;
- myocardial infarction;
- kurohwa uye vamwe.
Kudzidza kubuda kweropa mumidziyo yeperesi inoshandisa dzimwe nzvimbo, inonzi ultrasound windows. Mune dzimwe nzvimbo, mapfupa ehenya haatapudzi, kana kuti ane mavhenekeri ezvisikwa.
Kugadzirisa migumisiro ye dopplerography
Nekubatsira kwe dopplerography, nyanzvi inongoronga masvingo emudziyo, dzakapoteredza mishonga, mutungamiri nekukurumidzira kwekuyerera kweropa, kuvapo kwezvigadziro zvinodzivisa kubuda kweropa zvakakwana (plaques, thrombi). Mukuwedzera, nzvimbo uye kukotama kwemidziyo inoongororwa, uye zviratidzo zvinowanikwa zvinofananidzwa ne-normative.
Izvi zvinotevera zviyero zvakanyanya zvekuyerera kweropa zvinoongororwa:
- velocity of blood flow;
- systolic-diastolic chiyero - chiyero chepamusoro (munguva ye-systole) uye zvishoma (panguva ye diastole) ropa kubuda velocity;
- pulsation index - chiyero chekusiyanisa pakati pehuwandu uye zvishoma zvishoma zvekuyerera kweropa kusvika pachiyero chechikepe mumudziyo;
- iyo kupikisa index ndiyo chiyero pakati pechinyorwa mu systolic uye diastolic velocities uye systolic velocity;
- kureba kwechombo.
Nzira yekudzidzira yemhando yacho inobva pane zvidzidzo zveanyanzvi anoita nzira yacho. Zvakakoshawo kugadzirira kudzidza. Saka, varwere havasi kukurudzirwa kutora mishonga, kunwa tei kana kofi pazuva rekuongorora, utsi hwemaawa maviri kana maawa mashoma asati apera. Pamberi pekuongororwa kwemidziyo yeimpso, kudya kunokosha kunodiwa.
