Yintoni i-MRI yeLumbar?

Iskena seMRI sisebenzisa iimagnethi kunye namaza erediyo ukuthwebula imifanekiso ngaphakathi komzimba wakho ngaphandle kokwenza utyando. Ukuskena kuvumela ugqirha wakho ukuba abone izicwili ezithambileyo zomzimba wakho, njengezihlunu kunye namalungu, ukongeza kumathambo akho.

I-MRI inokwenziwa nakweliphi na ilungu lomzimba wakho. I-MRI ye-lumbar ivavanya ngokukodwa icandelo le-lumbar yomqolo wakho-ingingqi apho iingxaki zangasemva zihlala zivela khona.

Umqolo we-lumbosacral wenziwe ngamathambo amahlanu e-lumbar (L1 thru L5), i-sacrum (i-bony "shield" emazantsi omqolo wakho), kunye ne coccyx (umsila wethambo). Umqolo we-lumbosacral nawo unemithambo yegazi emikhulu, imithambo-luvo, imisipha, iigaments kunye ne-cartilage.

Kutheni i-MRI ye-lumbar yenziwe

Ugqirha wakho unokucebisa i-MRI ukuba ichaze ngcono okanye inyange iingxaki ngomqolo wakho. Intlungu enxulumene nokwenzakala, isifo, usulelo, okanye ezinye izinto ezinokubangela imeko yakho. Ugqirha wakho unokuyalela i-MRI ye-lumbar ukuba uneempawu ezilandelayo:

• umqolo obuhamba nefiva
• iziphene zokuzalwa ezichaphazela umqolo wakho
• ukwenzakala kumqolo wakho osezantsi
• Ukuqhubeka okanye iintlungu ezisezantsi ezisezantsi
• isifo sokugubhuka
• iingxaki ngesinyi sakho
• iimpawu zobuchopho okanye umhlaza womqolo
• ubuthathaka, ukuba ndindisholo, okanye ezinye iingxaki ngemilenze yakho

Ugqirha wakho unokuyalela i-MRI ye-lumbar ukuba ucwangciselwe uqhaqho lomqolo. I-lumbar MRI iya kubanceda bacwangcise inkqubo ngaphambi kokwenza ukusikwa.

Iskena seMRI sinika uhlobo olwahlukileyo lomfanekiso kwezinye iimvavanyo zokucinga njengeX-reyi, i-ultrasound, okanye iskena se-CT. I-MRI ye-lumbar spine ibonisa amathambo, iidiski, intambo yomqolo, kunye neendawo phakathi kwamathambo e-vertebral apho kudlula imithambo-luvo.

Umngcipheko we-lumbar MRI scan

Ngokungafaniyo ne-X-ray okanye i-CT scan, i-MRI ayisebenzisi imitha ye-ionizing. Kuthathwa njengenye indlela ekhuselekileyo, ngakumbi kubafazi abakhulelweyo kunye nabantwana abakhulayo. Nangona ngamanye amaxesha kukho iziphumo ebezingalindelekanga, zinqabile kakhulu. Ukuza kuthi ga ngoku, akukho ziphumo zibhaliweyo ezivela kumaza erediyo kunye neemagnethi ezisetyenzisiweyo kwiskena.

Kukho umngcipheko kubantu abanezinto ezifakwe kwisinyithi. Iimagnethi ezisetyenziswe kwi-MRI zinokubangela iingxaki nge-pacemaker okanye kubangele ukufakelwa izikhonkwane okanye izikhonkwane ukuba zitshintshe emzimbeni wakho.

Enye ingxaki kukungavumelani nedayi. Ngexesha loviwo lweMRI, idayi eyahlukileyo itofelwe kwigazi ukunika umfanekiso ocacileyo wemithambo yegazi kuloo ndawo iskenwayo. Uhlobo oluqhelekileyo lokungafani kwedayi yi-gadolinium. Ukunyanga komzimba kwidayi kuhlala kuthambile kwaye kulula ukuyilawula ngamayeza. Kodwa, ngamanye amaxesha ukusabela kwe-anaphylactic (kunye nokufa) kunokwenzeka.

Uyilungiselela njani i-MRI ye-lumbar

Ngaphambi kovavanyo, xelela ugqirha wakho ukuba unayo pacemaker. Ugqirha wakho unokucebisa enye indlela yokuhlola i-lumbar spine, enjenge-CT scan, kuxhomekeke kuhlobo lwe-pacemaker. Kodwa ezinye iimodeli zepacemaker zinokuphinda zenziwe ngokutsha ngaphambi kweMRI ukuze zingaphazanyiswa ngexesha lokuskena.

Ugqirha wakho uyakukucela ukuba ususe bonke ubucwebe kunye nokugqobhoza kwaye utshintshe ibe yingubo yasesibhedlele ngaphambi kokuskena. I-MRI isebenzisa oomazibuthe ngamanye amaxesha abanokutsala isinyithi. Qiniseka ukuba uxelela ugqirha wakho ukuba unayo nayiphi na into efakelwe isinyithi okanye ukuba kukho naziphi na ezi zinto zilandelayo emzimbeni wakho:

• Ivaluva zentliziyo ezingezizo
• umboniso
• Ukufakelwa
• izikhonkwane
• iipleyiti
• amalungu okanye amalungu afakelwayo
• izikrufu
• ukutya
• stents

Ukuba ugqirha wakho usebenzisa idayi eyahlukileyo, baxelele malunga naziphi na izinto ezibangelwa kukungabikho komzimba okanye uxabane nabo.

Ukuba u-claustrophobic, unokuziva ungakhululekanga ngelixa umatshini weMRI. Xelela ugqirha wakho malunga noku ukuze bakwazi ukukunika amayeza alwa noxinzelelo. Ngamanye amaxesha, unokuhlala phantsi ngexesha lokuskena. Isenokungakhuselekanga ukuqhuba emva koko xa ukhe wanikezela. Kwimeko apho, qiniseka ukuba ulungiselela ukukhwela ekhaya emva kwenkqubo.

I-MRI ye-lumbar yenziwa njani

Umatshini we-MRI ujongeka njenge-donut enkulu yentsimbi kunye neplastiki enebhentshi ekuhambisa kancinci embindini wokuvula. Uya kukhuseleka ngokupheleleyo ngaphakathi nangakujikeleze umatshini ukuba ulandele imiyalelo kagqirha wakho kwaye ususe yonke intsimbi. Yonke le nkqubo ingathatha kwimizuzu engama-30 ukuya kwengama-90.

Ukuba kuya kusetyenziswa idayi eyahlukileyo, umongikazi okanye ugqirha uya kufaka idayi eyahlukileyo ngombhobho ofakwe kolunye lweemithambo yakho. Ngamanye amaxesha, kuya kufuneka ulinde ukuya kuthi ga kwiyure ukuze idayi isebenze ngendlela yakho yegazi lakho nakumqolo wakho.

Uchwepheshe we-MRI uya kulala ebhentshini, nokuba ungasemva, ecaleni okanye esiswini. Unokufumana umqamelo okanye ingubo ukuba unengxaki yokulala ebhentshini. Ingcali iya kulawula ukuhamba kwebhentshi kwelinye igumbi. Baya kuba nakho ukunxibelelana nawe ngesithethi kumatshini.

Umatshini uya kwenza ingxolo enkulu kunye nokugungqa ingxolo njengoko ithatha imifanekiso. Izibhedlele ezininzi zibonelela ngee-earplugs, ngelixa ezinye zinomabonakude okanye ii-headphone zomculo ukukunceda udlulise ixesha.

Njengoko imifanekiso ithathwa, igcisa liya kukucela ukuba ubambe umphefumlo wakho imizuzwana embalwa. Awuyi kuva nantoni na ngexesha lovavanyo.

Emva kwe-MRI ye-lumbar

Emva kovavanyo, ukhululekile ukuba uhambe malunga nosuku lwakho. Nangona kunjalo, ukuba uthathe umthomalalisi ngaphambi kwenkqubo, akufuneki uqhube.

Ukuba imifanekiso yakho ye-MRI yayiqikelelwa kwifilimu, kungathatha iiyure ezimbalwa ukuze ifilimu iphuhle. Kuya kuthatha ixesha ukuba ugqirha wakho aqwalasele imifanekiso kwaye atolike iziphumo. Oomatshini banamhlanje babonisa imifanekiso kwikhompyuter ukuze ugqirha ayibone ngokukhawuleza.

Ingathatha iveki okanye nangaphezulu ukufumana zonke iziphumo kwi-MRI yakho. Xa iziphumo zifumaneka, ugqirha wakho uya kukubiza ukuba uzihlole kwaye uxoxe ngamanyathelo alandelayo kunyango lwakho.
