Iyini i-MRI ye-lumbar?

Iskena se-MRI sisebenzisa ozibuthe namagagasi omsakazo ukuthatha izithombe ngaphakathi komzimba wakho ngaphandle kokwenza imbobo yokuhlinzwa. Ukuskena kuvumela udokotela wakho ukuthi abone izicubu ezithambile zomzimba wakho, njengezicubu nezitho, ngaphezu kwamathambo akho.

I-MRI ingenziwa kunoma iyiphi ingxenye yomzimba wakho. I-MRI ye-lumbar ihlola ngqo isigaba se-lumbar somgogodla wakho - isifunda lapho izinkinga zangemuva zivame ukuvela khona.

Umgogodla we-lumbosacral wenziwa ngamathambo amahlanu e-lumbar vertebral (L1 thru L5), i-sacrum (i-bony "shield" ezansi yomgogodla wakho), kanye ne-coccyx (umsila wethambo). Umgogodla we-lumbosacral nawo unemithambo yegazi emikhulu, izinzwa, imisipha, imisipha kanye noqwanga.

Kungani kwenziwa i-MRI ye-lumbar

Udokotela wakho angancoma i-MRI ukuxilonga kangcono noma ukwelapha izinkinga ngomgogodla wakho. Ubuhlungu obuhlobene nokulimala, izifo, ukutheleleka, noma ezinye izinto kungadala isimo sakho. Udokotela wakho angalawula i-MRI ye-lumbar uma unezimpawu ezilandelayo:

• Ubuhlungu beqolo obuhambisana nomkhuhlane
• ukukhubazeka kokuzalwa okuthinta umgogodla wakho
• ukulimala komgogodla wakho ophansi
• izinhlungu eziqhubekayo noma ezinzima zomqolo ophansi
• i-multiple sclerosis
• izinkinga ngesinye sakho
• izimpawu zobuchopho noma umdlavuza womgogodla
• ubuthakathaka, ukuba ndikindiki, noma ezinye izinkinga ngemilenze yakho

Udokotela wakho angaphinde a-ode i-MRI ye-lumbar uma uhlelelwe ukuhlinzwa umgogodla. I-lumbar MRI izobasiza ukuhlela inqubo ngaphambi kokwenza imbobo.

Ukuskena kwe-MRI kunikeza uhlobo oluhlukile lwesithombe kusuka kwezinye izivivinyo zokucabanga njenge-X-ray, i-ultrasound, noma i-CT scan. I-MRI yomgogodla we-lumbar ikhombisa amathambo, amadiski, umgogodla, nezikhala eziphakathi kwamathambo e-vertebral lapho izinzwa zidlula khona.

Ubungozi beskena se-lumbar MRI

Ngokungafani ne-X-ray noma i-CT scan, i-MRI ayisebenzisi imisebe ye-ionizing. Kubhekwa njengenye indlela ephephile, ikakhulukazi kwabesifazane abakhulelwe nezingane ezikhulayo. Yize kwesinye isikhathi kunemiphumela engemihle, ayivelakancane ngokweqile. Kuze kube manje, lapha akubanga khona imiphumela emibi ebhaliwe evela kumagagasi omsakazo nozibuthe abasetshenziswe kuskena.

Kukhona ubungozi kubantu abanezimila eziqukethe izinsimbi. Omazibuthe abasetshenziswe kwi-MRI kungaholela ezinkingeni ngama-pacemaker noma kubangele ukufakwa kwezikulufo noma izikhonkwane kushintshe emzimbeni wakho.

Enye inkinga ukuxazulula idayi yokuqhathanisa. Ngesikhathi sokuhlolwa okuthile kwe-MRI, udayi wokuqhathanisa ufakwa egazini ukuze kunikezwe isithombe esicacile semithambo yegazi endaweni eskenwayo. Uhlobo oluvame kakhulu lwedayi lokuqhathanisa yi-gadolinium. Ukungezwani komzimba nodayi kuvame ukuba mnene futhi kube lula ukuwalawula ngemithi. Kepha, kwesinye isikhathi ukusabela kwe-anaphylactic (ngisho nokufa) kungenzeka.

Ungayilungiselela kanjani i-MRI ye-lumbar

Ngaphambi kokuhlolwa, tshela udokotela wakho uma une-pacemaker. Udokotela wakho angase asikisele enye indlela yokuhlola umgogodla wakho we-lumbar, njenge-CT scan, kuye ngohlobo lwe-pacemaker. Kodwa amanye amamodeli we-pacemaker angahlelwa kabusha ngaphambi kwe-MRI ukuze angaphazanyiswa ngesikhathi sokuskena.

Udokotela wakho uzokucela ukuthi ususe bonke ubucwebe nokubhoboza bese ushintsha ube yingubo yesibhedlela ngaphambi kokuthwebula. I-MRI isebenzisa ozibuthe kwesinye isikhathi abangaheha izinsimbi. Qiniseka ukuthi utshela udokotela wakho uma unezinsimbi ezifakiwe noma uma kukhona izinto ezilandelayo emzimbeni wakho:

• ama-valve enhliziyo yokufakelwa
• iziqeshana
• okufakelwa
• izikhonkwane
• amapuleti
• amalunga wokufakelwa noma izitho
• ngezikulufo
• ukudla okuyisisekelo
• ama-stents

Uma udokotela wakho esebenzisa udayi wokuqhathanisa, batshele nganoma yikuphi ukungezwani komzimba onakho noma ukusabela okweqile oke waba nakho.

Uma u-claustrophobic, ungazizwa ungakhululekile ngenkathi usemshinini we-MRI. Tshela udokotela wakho ngalokhu ukuze bakunikeze imishanguzo yokulwa nokukhathazeka. Kwezinye izimo, ungahle uthanjiswe ngesikhathi sokuskena. Kungenzeka kungaphephile ukushayela ngemuva kwalokho uma uthanjisiwe. Uma kunjalo, qiniseka ukuthi uhlela ukugibela ekhaya ngemuva kwenqubo.

Isebenza kanjani i-lumbar MRI

Umshini we-MRI ubukeka njengedonathi enkulu yensimbi nepulasitiki enebhentshi ekuyisa kancane kancane enkabeni yomnyango. Uzobe uphephe ngokuphelele emshinini naseduze kwakho uma ulandele iziyalezo zikadokotela wakho futhi wasusa yonke insimbi. Yonke le nqubo ingathatha kusuka kumizuzu engama-30 kuye kwengu-90.

Uma kuzosetshenziswa udayi wokuqhathanisa, umhlengikazi noma udokotela uzojova udayi wokuqhathanisa ngepayipi elifakwe kolunye lwemithambo yakho. Kwezinye izimo, kungadingeka ukuthi ulinde kuze kube ihora ukuze udayi usebenze ngendlela yakho egazini lakho nasemgogodleni wakho.

Uchwepheshe we-MRI uzokulala ebhentshini, kungaba emuva, ohlangothini, noma esiswini. Ungathola umcamelo noma ingubo uma unenkinga yokulala ebhentshini. Uchwepheshe uzolawula ukuhamba kwebhentshi kusuka kwelinye igumbi. Bazokwazi ukuxhumana nawe ngesipikha emshinini.

Umshini uzokwenza umsindo omkhulu wokumumatha nokushaya njengoba kuthatha izithombe. Izibhedlela eziningi zinikeza okufakwa ezindlebeni, kuyilapho ezinye zinamathelevishini noma amahedfoni omculo ukukusiza ukudlulisa isikhathi.

Njengoba izithombe zithathwa, uchwepheshe uzokucela ukuthi ubambe umoya imizuzwana embalwa. Ngeke uzwe lutho ngesikhathi sokuhlolwa.

Ngemuva kwe-MRI ye-lumbar

Ngemuva kokuhlolwa, ukhululekile ukuqhubeka nosuku lwakho. Kodwa-ke, uma uthathe izidambisi ngaphambi kwenqubo, akufanele ushayele.

Uma izithombe zakho ze-MRI ziveliswe kwifilimu, kungathatha amahora ambalwa ukuthi ifilimu ikhule. Kuzothatha nesikhathi ukuthi udokotela wakho abukeze izithombe futhi ahumushe imiphumela. Imishini eminingi yesimanje ibonisa izithombe kukhompyutha ukuze udokotela wakho azibuke ngokushesha.

Kungathatha kuze kube yisonto noma ngaphezulu ukuthola yonke imiphumela evela ku-MRI yakho. Lapho imiphumela itholakala, udokotela wakho uzokubiza ukuthi uyibuyekeze bese uxoxa ngezinyathelo ezilandelayo ekwelashweni kwakho.
