Ushwankathelo

Zombini i-MRI kunye ne-MRA zizinto ezingafunekiyo kwaye zibuhlungu izixhobo zokuchonga ezisetyenziselwa ukujonga izicubu, amathambo, okanye amalungu ngaphakathi komzimba.

I-MRI (imaging resonance imaging) yenza imifanekiso eneenkcukacha ngamalungu kunye nezicubu. I-MRA (i-magnetic resonance angiography) ijolise ngakumbi kwimithambo yegazi kunezicubu eziyingqongileyo.

Ukuba ugqirha wakho ukhangela imiba ngaphakathi kwimithambo yegazi, baya kuhlala behlela i-MRA yakho. Nantsi into ekufuneka uyazi ngezi mvavanyo zimbini:

Yintoni iMRI?

I-MRI luhlobo lokuskena olusetyenziselwa ukujonga amalungu omzimba angaphakathi.

Oku kunokubandakanya amalungu, izicubu kunye namathambo. Umatshini we-MRI wenza umazibuthe kwaye emva koko utsiba amaza erediyo emzimbeni osebenza kwimephu yenxalenye yomzimba efundwayo.

Ngamanye amaxesha ngexesha le-MRIs, ugqirha kufuneka asebenzise iiarhente zokungafaniyo ezinceda i-radiologist ukuba ibone ilungu lomzimba liskenwe ngokucokisekileyo.

Yintoni i-MRA?

I-MRA luhlobo lovavanyo lweMRI.

Ngokwesiqhelo, i-MRA yenziwa ngokudibeneyo neMRI. Ii-MRAs zavela kwii-MRIs ukunika oogqirha amandla okujonga imithambo yegazi ngokucokisekileyo.

I-MRA yenziwe ngemiqondiso ye-MRI ebandakanya idatha yendawo.

Zenziwa njani ii-MRIs kunye nee-MRA?

Ngaphambi kovavanyo lwe-MRI okanye lwe-MRA, uya kucelwa ukuba unayo nayiphi na imiba eya kuphazamisa umatshini we-MRI okanye ukhuseleko lwakho.

Oku kunokubandakanya:

• Iitattoos
• ukugqobhoza
• izixhobo zonyango
• Ukufakelwa
• abenzi boxolo
• ukutshintshwa ngokudibeneyo
• isinyithi salo naluphi na uhlobo

I-MRI yenziwa ngemagnethi, ke ngoko izinto ezinesinyithi zinokubangela ingozi kumatshini nakumzimba wakho.

Ukuba ufumana i-MRA, unokufuna iarhente eyahlukileyo. Oku kuya kutofelwa kwimithambo yakho. Iya kusetyenziselwa ukunika imifanekiso ngokungafaniyo ngakumbi ukuze imithambo okanye imithambo yakho ibe lula ukuyibona.

Unokunikwa ii-earplugs okanye ukhuseleko lweendlebe zohlobo oluthile. Umatshini uyangxola kwaye unakho ukonakalisa iindlebe zakho.

Uya kucelwa ukuba ubeke etafileni. Itheyibhile iya kutyibilika kumatshini.

Isenokuziva iqinile ngaphakathi kumatshini. Ukuba ufumene i-claustrophobia ngaphambili, kuya kufuneka wazise ugqirha wakho ngaphambi kwenkqubo.

Imingcipheko yeMRI kunye neMRA

Umngcipheko we-MRIs kunye nee-MRAs ziyafana.

Ukuba unesidingo searhente yokuchasana efakwa ngaphakathi, unokuba nengozi eyongeziweyo enxulumene nenaliti. Eminye imingcipheko inokubandakanya:

• ukufudumeza umzimba
• ulusu luvutha kwiradiofrequency
• iimpendulo zemagneti kwizinto zomzimba wakho
• umonakalo wokuva

Imingcipheko yezempilo inqabile kakhulu nge-MRIs kunye nee-MRAs. I-FDA ifumana unyaka kwizigidi ze-MRI ezenziwe.

Kutheni i-MRA vs. MRI?

Zombini ii-MRAs kunye nee-MRIs zisetyenziselwa ukujonga amalungu angaphakathi omzimba.

Ii-MRIs zisetyenziselwa ukungahambi kakuhle kwengqondo, ukulimala ngokudibeneyo, kunye nokunye okungaqhelekanga ngelixa ii-MRAs zinoku-odolwa:

• imivumbo
• Ukudibana kwe-aortic
• isifo se-carotid
• isifo sentliziyo
• Eminye imicimbi yegazi

Yise kude

Ii-MRIs kunye nee-MRAs azifani kakhulu. Ukuskena kwe-MRA luhlobo lweMRI kwaye lwenziwa ngomatshini omnye.

Umahluko kuphela kukuba i-MRA ithatha imifanekiso eneenkcukacha zemithambo yegazi kunezitho okanye izicwili ezibangqongileyo. Ugqirha wakho uya kuncomela enye okanye zombini kuxhomekeke kwiimfuno zabo zokwenza uxilongo olufanelekileyo.
