Ukubuka konke
Kokubili i-MRI ne-MRA kungamathuluzi okuxilonga angenasifo futhi angenabuhlungu asetshenziselwa ukubuka izicubu, amathambo, noma izitho ngaphakathi komzimba.
I-MRI (imaging resonance imaging) idala izithombe eziningiliziwe zezitho nezicubu. I-MRA (magnetic resonance angiography) igxila kakhulu emithanjeni yegazi kunezicubu ezizungezile.
Uma udokotela wakho efuna izingqinamba ngaphakathi kwemithambo yegazi, bavame ukukuhlelela i-MRA. Nakhu okudingeka ukwazi mayelana nalezi zivivinyo ezimbili:
Yini i-MRI?
I-MRI wuhlobo lokuskena olusetshenziselwa ukubuka izitho zomzimba zangaphakathi.
Lokhu kungafaka izitho, izicubu namathambo. Umshini we-MRI udala amandla kazibuthe bese uqhuma amaza omsakazo emzimbeni osebenza ukudweba ingxenye yomzimba eskeniwe.
Kwesinye isikhathi ngesikhathi sama-MRIs, udokotela kufanele asebenzise izinto zokuqhathanisa ezisiza i-radiologist ukubona ingxenye yomzimba iskenwa kahle.
Yini i-MRA?
I-MRA uhlobo lokuhlolwa kwe-MRI.
Imvamisa, i-MRA yenziwa ngokubambisana ne-MRI. Ama-MRAs aqhamuka kuma-MRIs ukunikeza odokotela amandla okubuka imithambo yegazi ngokuphelele.
I-MRA yakhiwe ngamasiginali we-MRI afaka imininingwane yendawo.
Enziwa kanjani ama-MRIs nama-MRA?
Ngaphambi kokuhlolwa kwe-MRI noma i-MRA, uzobuzwa ukuthi ngabe unezinkinga ezingaphazamisa umshini we-MRI noma ukuphepha kwakho.
Lokhu kungafaka:
- ama-tattoo
- ukubhoboza
- amadivayisi wezokwelapha
- okufakelwa
- abenzi benhliziyo
- ukufaka ngokuhlanganyela
- insimbi yanoma yiluphi uhlobo
I-MRI yenziwa ngozibuthe, ngakho-ke izinto ezinensimbi zingadala ingozi emshinini nasemzimbeni wakho.
Uma uthola i-MRA, ungahle udinge umenzeli ohlukile. Lokhu kuzofakwa emithanjeni yakho. Izosetshenziselwa ukunikeza izithombe umehluko omkhulu ukuze imithambo yakho noma imithambo yegazi kube lula ukukubona.
Ungahle unikezwe ama-earplugs noma ukuvikelwa kwezindlebe ngohlobo oluthile. Umshini unomsindo futhi unamandla okulimaza ukuzwa kwakho.
Uzocelwa ukuthi ubeke etafuleni. Itafula lizosheleleka emshinini.
Kungazizwa kuqinile ngaphakathi komshini. Uma uke wabhekana ne-claustrophobia esikhathini esedlule, kufanele wazise udokotela wakho ngaphambi kwenqubo.
Izingozi zeMRI neMRA
Izingozi zama-MRIs nama-MRAs ziyefana.
Uma unesidingo se-ejenti yokuhlukanisa ngaphakathi, ungahle ube nengozi eyengeziwe ehambisana nomjovo. Ezinye izingozi zingabandakanya:
- Ukushisa komzimba
- ukusha kwesikhumba kusuka kuma-radiofrequency
- ukusabela kazibuthe okuvela ezintweni ezingaphakathi komzimba wakho
- ukulimala kokuzwa
Izingozi zezempilo azivamile ngama-MRIs nama-MRAs. I-FDA ithola unyaka ezigidini zezikena ze-MRI ezenziwe.
Kungani i-MRA vs. MRI?
Kokubili ama-MRAs nama-MRIs asetshenziselwa ukubuka izingxenye zangaphakathi zomzimba.
Ama-MRIs asetshenziselwa ukukhubazeka ebuchosheni, ukulimala okuhlangene, nokunye okungajwayelekile ngenkathi ama-MRA anga-oda nge:
- imivimbo
- ukuguquguquka kwe-aorta
- isifo semithambo carotid
- Isifo senhliziyo
- ezinye izindaba zomthambo wegazi
Ukudla okudlela endlini
Ama-MRIs nama-MRA awahlukile kakhulu. Ukuskena kwe-MRA kuyindlela ye-MRI futhi kwenziwa ngomshini ofanayo.
Umehluko kuphela ukuthi i-MRA ithatha izithombe ezinemininingwane eminingi ngemithambo yegazi kunezitho noma izicubu ezizungezile. Udokotela wakho uzoncoma eyodwa noma kokubili kuye ngezidingo zabo zokwenza ukuxilongwa okufanele.
