I-MRI (imagination magontic resonance imaging) yindlela yokuhlolisisa izitho kunye nezicubu, ezinamaxesha amaninzi kubaluleke kakhulu ekumiseni i-diagnostic echanekileyo kunye nokunyanga unyango. Le ndlela yenza ukuba kube lula ukufumana umfanekiso ocacileyo, ovumela ukutyhila impawu ezincinci kwinkqubo ye-pathological process.
Ngokuqhelekileyo, i-MRI isetyenziselwa ukuxilonga izitho zenkqubo ye-nervous central, inkqubo ye-musculoskeletal, izitho zangaphakathi, umgudu. Ukubonakaliswa kubangelwa ukulinganiselwa kweempendulo ze-electromagnetic zama-athomu e-hydrogen ekuphenduleni isenzo sabo ngamaza okombane kwi-field magnetic. Uhlobo oluthile lolwazi lwenkqubo lwandiswa ngokusetyenziswa kwamagunya ahlukeneyo.
Ngaba inkqubo ye-MRI yingozi?
Ukucatshulwa kwe-magnontic resonance kuthathwa njengengozi kwenkqubo yomzimba, eqinisekiswa zizifundo ezininzi. Kodwa nangona kunjalo, kukho ukuphikisana nokufezekiswa kwayo, ngoko kuyimfuneko ukwenza iMRI kuphela ngokwalathiso lwegqirha kwaye uqwalasele iinkqubo zokukhusela.
Kufuneka kuqondwe ukuba ukuchasana kwe-MRI akuhambelani nemiphumo enobungozi yendlela, kodwa kwimimiselo yesigulane ngasinye kunye nemingcele ehambelana nomfuno wokuhlala kwindawo evuliwe phantsi kwesenzo se-magnetic field. Oku kubangelwa yimpembelelo yintsimi kwizinto zetsimbi, izinto ze-elektroniki kunye ne-ferromagnetic ezingatholakala kumzimba womntu. Impembelelo yamagnetic ingakhokelela ekuphazamiseni emsebenzini wabo, ukufuduka.
Ukungqinelana kwiMRI
Zonke iimeko, apho i-imagination magontic resonance imaging ingenakwenzeka, iyahlula ngamaqela amabini: isiqhelo kunye nokuchasene ngokupheleleyo. Ukuchasana okumalunga neendlela ezinokumiselwa kuzo, kodwa ngeemeko ezithile. Ubungqina bokuchasene ngokupheleleyo ngumqathango wenkqubo yokuxilonga, engenakukhanselwa ngonaphakade okanye ixesha elide.
Ngoko, i-MRI engqinelanayo yile:
- Ukungaphumeleli kwentliziyo ;
- ukukhulelwa (yokuqala yesithathu);
- iipompo;
- izivalo zentliziyo;
- iziqeshana ze-hemostatic;
- abavuseleli kwinkqubo yeentlungu;
- i-claustrophobia (ukwenzela ukuhlolwa kwiitampu ze-tunnel);
- imizimba emzimbeni, eyenziwe ngamacwecwe anezinyithi;
- jikelele imeko enkulu yesigulane.
Ukuchaswa okungaqhelekanga kwe-MRI ngolu hlobo lulandelayo:
- ubukho be-pacemaker;
- ifakwe i-Ilizarov;
- izixhobo ezinkulu zetsimbi, iziqhekeza ze-ferromagnetic;
- ukufakwa kwendlebe ephakathi;
- iziqeshana ze-hemostatic ezenziwe ngetsimbi.
Ezi zingentla zingqiniswanga zibhekisela kwi-MRI yentloko (ingqondo), umlenze , isisu, izigulane zamancinci kunye nayiphi na indawo yomzimba. Ukuba isiguli asinayo nayiphi na ingqinisiso ekufundweni, i-MRI inokuphindwa kaninzi.
Ukungqinelana kwiMRI ngokuphambene
Kwezinye iimeko, i-MRI iyadingeka ngokusetyenziswa kokuchasene-isilwanyana esikhethekileyo esilawulwa ngaphakathi kunye nokuvumela "ukutshisa" izitho zangaphakathi. Njengomthetho, amalungiselelo okungafaniyo angabangeli iimpembelelo kunye nemiphumo emibi, ayinayo imiphumo emibi emzimbeni. Ngako oko, ukungqinelani kwe-MRI kunye ne-ejenti eyahlukileyo kubandakanya kuphela i-trimester yokuqala yokukhulelwa (ngeli xesha, umntwana okhulelwe kakhulu), kunye nokunyanzeliswa komntu ngamnye kumacandelo e-ejenti eyahlukileyo.
