Ukutshatyalaliswa kwezinto ngeenqanawa yindlela yokuhlaziya yindlela yanamhlanje evumela ukuba ufunde i-bed bed ye-vascular ngokusebenzisa i-ultrasound. Amanye amagama ale ndlela yinkwenkwe yokukhangela iinqanawa, i-ultrasound of vessels.
I-Dopplerography inikezela ngolwazi olupheleleyo kwisakhiwo semithambo yegazi kunye nendlela igazi elihamba ngayo kuwo. Oku kwenza kube lula ukuchonga iingxaki ezahlukahlukeneyo kumanyathelo okuqala, ukukhusela ukuphuhliswa kwezilwanyana ezinzima. Ukongeza kwi-diagnostic, le ndlela isetyenziselwa ukukhetha indlela yokonyango nokuvavanya iziphumo zayo.
Inkqubo eyenziwa ngoncedo lwama-ultrasound rays, asetyenziswa kwi-ultrasound evamile yezitho ezahlukeneyo. Nangona kunjalo, kule meko isetyenzisi esithile esisetyenziswayo esivela kwaye ifumana amaza aphezulu, esebenza ngomgaqo weDoppler. Kule meko, ubuchule bukhuselekile kwaye bubuhlungu kwaye buya kwenziwa ngokuphindaphindiweyo ukuba kuyimfuneko.
Iintlobo kunye nezibonakaliso zokuchithwa kweevenkile
Olu phofu, njengomthetho, lonyulwa ngokusekelwe kwizikhalazo zesigulane kunye nesimo sesifundo sesi sifo, esivumela umntu ukuba akrokre i-pathology. Ngethuba le nkqubo, kuxhomekeke kwindawo yokukhutshwa kweempahla, iisenjini ezineendlela ezahlukeneyo ze-ultrasound zisetyenziswa. Khawucinge ukuba zeziphi iimpawu ezingabelwa kwiindidi ezahlukileyo ze-dopplerography.
1. Ukutshatyalaliswa kwezinto ezenziwe entanjeni nentloko:
- intloko, isisu;
- ukulahlekelwa kwengqondo;
- ukukhubazeka kwememori;
- izifo zokulala;
- uxinzelelo lwegazi luyatshintsha;
- ingxolo ezindlebeni;
- "Izimpukane" phambi kwamehlo , njl.
2. I-ultrasonic dopplerography yeempahla zephantsi nezisezantsi:
- ukukhanya kwezandla, iinyawo;
- ukuvuvuka kwezandla, iinyawo;
- ukuxinwa, ukunyuka kwamalungu;
- intlungu xa uhamba;
- ukulahlekelwa kwamandla emisipha ezandleni;
- utshintshe umbala wesikhumba weengcambu, njl.
3. Ukutshatyalaliswa kweengcamango zeentso:
- intlungu kwingingqi ye-lumbar;
- uxinzelelo lwegazi luyatshintsha;
- umahluko phakathi kobukhulu beentso ezikhohlo kunye nekunene;
- polyuria nabanye.
I-Transcranial doppleral doppleral ye-vessels ye-cerebral
I-transcranial dopplerography yeenqwelo ze-cerebral yenziwa ngenjongo yokutyhila izilonda zeenqanawa ezingenanto kunye neengxaki ezahlukeneyo zokuhamba kwegazi kuzo. Le nkqubo iqhutyelwa, ngokukodwa, ngoku:
- migraines;
- i-vegetative vascular dystonia ;
- i-craniocebral trauma;
- i-myocardial infarction;
- ukubetha kunye nabanye.
Ukufunda ukuhamba kwegazi kwiinqanawa ze-cerebral sebenzisa iindawo ezithile, ezibizwa ngokuba ngamawindi e-ultrasound. Kule mimandla, amathambo enkayi aphantsi, okanye avulekileyo.
Ukucacisa iziphumo ze-dopplerography
Ngoncedo lwe-dopplerography, ingcali ihlola iindonga zomkhumbi, izicubu ezijikelezileyo, ulwalathiso kunye nokukhawuleza kokuhamba kwegazi, ubukho beendlela ezivimbela ukujikeleza kwegazi ngokuqhelekileyo (i-plaques, thrombi). Ukongezelela, indawo kunye nokugoba kweempahla zitshekishwe, kwaye izalathisi ezifunyenweyo zifaniswa neziqhelo.
Iiparamitha ezilandelayo eziphambili zokuhamba kwegazi ziyahlolwa:
- ukujikeleza kwegazi;
- Umlinganiselo we-systolic-diastolic - umlinganiselo wesigxina (ngexesha le-syole) kunye ubuncinci (ngexesha le-diastole) i-blood flow flow;
- isalathiso senkcazo - umlinganiselo wokohluko phakathi kobunzima obuncinane kunye nobuncinci bokuhamba kwegazi ukuya kwisantya esiphezulu kwisitya;
- Inkcazo yokuchasana ngumlinganiselo phakathi kohlula kwiimpawu ze-systolic kunye ne-diastolic kunye ne-systolic velocity;
- ububanzi bomkhumbi.
Ubume benkcazelo yendlela exhomekeke kakhulu kwiimfundo zengcali eqhuba le nkqubo. Kubalulekile ukulungiselela isifundo. Ngoko ke, izigulane azikhuthazwa ukuba zithathe amayeza, zisele itiye okanye ikhofi ngosuku loviwo, umsi we-2 okanye iiyure ezingaphantsi kwenkqubo. Ngaphambi kokuxilongwa kwemikhumbi yeentso, kufuneka ukutya okukhethekileyo.
