Ukunyatheliswa kwezinto zokudoba kuyindlela yesimanje yokuxilonga evumela ukutadisha isimo sombhede wamasongo nge-ultrasound. Amanye amagama alo mbandela ukukhishwa kwe-duplex kwezitsha, ama-ultrasound of vessels.
I-Dopplerography inikeza ulwazi oluphelele mayelana nesakhiwo semithambo yegazi nendlela igazi elihamba ngayo kuwo. Lokhu kwenza kube lula ukubona izinkinga ezihlukahlukene ezinyathelweni zokuqala, ukuvimbela ukuthuthukiswa kwezifo ezinzima. Ngaphandle kokuxilongwa, le ndlela isetshenziselwa ukukhetha indlela yokwelashwa nokuhlola imiphumela yayo.
Inqubo yenziwa ngosizo lwama-ultrasound rays, asetshenziselwa i-ultrasound evamile yezitho ezihlukahlukene. Noma kunjalo, kulokhu kusetshenziswa inzwa ekhethekile ephuma futhi ithola amagagasi e-ultrasonic, isebenza ngesimiso somphumela we-Doppler. Kulokhu, le nqubo iphephile futhi ingenabuhlungu futhi ingenziwa ngokuphindaphindiwe uma kunesidingo.
Izinhlobo nezinkomba zokudonswa kwezinto zokudoba
Lolu cwaningo, njengombuso, luqokwa ngokusekelwe kwezikhalazo zesiguli kanye nesimo sesifundo sesifo, okuvumela umuntu ukuba asolise isifo sezinthambo. Ngenkathi yenqubo, kuye ngokuthi indawo izitsha zikhona, izinzwa ezinezimo ezahlukene ze-ultrasound zisetshenziswa. Cabanga ukuthi yiziphi izimpawu ezingabelwa ngezinhlobo ezahlukene ze-dopplerography.
1. Ukuhlukumezeka kwezitsha zentanyeni nekhanda:
- ikhanda, isizungu;
- ukulahlekelwa kokuqonda;
- ukukhubazeka kwememori;
- ukuphazamiseka kokulala;
- ukushintsha kwegazi;
- umsindo ezindlebeni;
- "Izimpukane" phambi kwamehlo , njll.
2. I-ultrasonic dopplerography yezitsha zamaphethelo aphansi nangaphezulu:
- ukukhanya kwezandla, izinyawo;
- ukuvuvukala kwezandla, izinyawo;
- ukuphazamiseka, ukuquleka kwamalungu;
- ubuhlungu lapho uhamba;
- ukulahlekelwa kwamandla emisipha ezandleni;
- shintsha umbala wesikhumba wemikhawulo, njll.
3. Ukulandelana kwezidakamizwa zemikhumbi yezinso:
- ubuhlungu esifundeni se-lumbar;
- ukushintsha kwegazi;
- umehluko ngobukhulu bezinso zesobunxele nezokudla;
- polyuria nabanye.
I-transcranial dopplerography yemikhumbi ye-cerebral
I-transcranial dopplerography yemikhumbi ye-cerebral yenziwa ngenhloso yokudalula izilonda zemikhumbi engenazo izifo nezinkinga ezihlukahlukene zokugeleza kwegazi kuzo. Le nqubo yenziwa, ikakhulukazi, nge:
- i-migraines;
- i-dystonia yemifino ye-vegetative ;
- i-craniocerebral trauma;
- i-infarction ye-myocardial;
- ukushaywa komzimba kanye nabanye.
Ukuze ufunde ukugeleza kwegazi emifuleni ye-cerebral sebenzisa izindawo ezithile, okuthiwa amawindi e-ultrasound. Kulezi zindawo, amathambo e-skull ayencane, noma avulekile.
Ukucacisa imiphumela ye-dopplerography
Ngosizo lwe-dopplerography, ochwepheshe uhlola izindonga zomkhumbi, izicubu ezizungezile, isiqondiso nesivinini sokugeleza kwegazi, ukutholakala kwezinto ezivimbela ukugeleza kwegazi okujwayelekile (amapulethi, thrombi). Ngaphezu kwalokho, indawo kanye nokugoba kwezitsha zihlolwe, futhi izinkomba ezitholakalayo zifaniswa nama-normative.
Izilinganiso ezilandelayo eziyinhloko zokugeleza kwegazi zihlolwa:
- ukuvinjelwa kwegazi;
- isilinganiso se-systolic-diastolic - isilinganiso sobukhulu (ngesikhathi se-syole) kanye nesilinganiso esincane (ngesikhathi se-diastole) segazi velocity;
- Inkomba ye-pulsation - isilinganiso sokwehluka phakathi kwamandla aphansi kanye nesilinganiso esincane sokugeleza kwegazi kuya esivumelwaneni esivamile emkhunjini;
- Inkomba yokumelana yilezi zilinganiso eziphakathi kwemikhawulo ye-systolic ne-diastolic velocities kanye ne-systolic velocity;
- ububanzi bomkhumbi.
Indlela efundisayo yale ndlela incike kakhulu ekufundeni kochwepheshe owenza inqubo. Kubalulekile futhi ukulungiselela isifundo. Ngakho-ke, iziguli azikhuthazwa ukuthatha imithi, ukuphuza itiye noma ikhofi ngosuku lokuhlolwa, ukubhema amahora amabili noma ngaphansi ngaphambi kwenqubo. Ngaphambi kokutholakala kwemikhumbi yezinso, kudingeka ukudla okukhethekile.
