Ukuskena iLumbar MRI

Iskena se-lumbar imaging resonance imaging (MRI) esisebenzisa amandla avela kwiimagnethi ezinamandla ukwenza imifanekiso yenxalenye esezantsi yomqolo (i-lumbar spine).

I-MRI ayisebenzisi i-radiation (x-ray).

Imifanekiso enye ye-MRI ibizwa ngokuba zizilayi. Imifanekiso inokugcinwa kwikhompyuter okanye iprintwe kwifilimu. Uvavanyo olunye luvelisa imifanekiso emininzi.

Uviwo olunxulumene noko lubandakanya:

• Ukuvavanywa komlomo wesibeleko (intamo ye-MRI)
• IMRI

Uya kunxiba ilokhwe yasesibhedlele okanye iimpahla ngaphandle kwezithonga zentsimbi okanye iziphu (ezinje ngezikipa kunye nesikipa). Qiniseka ukuba ukhulula iwotshi yakho, ubucwebe kunye neewotshi. Ezinye iintlobo zentsimbi zinokubangela imifanekiso engacacanga.

Uya kulala kwitafile emxinwa engena kwishubhu enkulu efana netonela.

Ezinye iimviwo zifuna idayi ekhethekileyo (umahluko). Uninzi lwexesha, uya kuyifumana idayi nge-vein (IV) esandleni sakho okanye engalweni ngaphambi kovavanyo. Unokufumana idayi ngenaliti. Idayi inceda i-radiologist ibone iindawo ezithile ngokucacileyo.

Ngexesha le-MRI, umntu osebenza kumatshini uya kukujonga ukwelinye igumbi. Uvavanyo luhlala luhlala kwimizuzu engama-30 ukuya kuma-60, kodwa lungathatha ixesha elide.

Unokucelwa ukuba ungatyi okanye usele nantoni na iiyure ezi-4 ukuya kwezi-6 ngaphambi kokuskena.

Xelela umboneleli wakho wezempilo ukuba woyika indawo ezivaliweyo (une-claustrophobia). Unokunikwa iyeza lokukunceda uzive usozela kwaye ungakhathazeki kangako. Umboneleli wakho unokucebisa nge-MRI "evulekileyo", apho umatshini ungekho kufutshane nomzimba.

Ngaphambi kovavanyo, xelela umboneleli wakho ukuba unayo:

• Iiklip ze-aneurysm zengqondo
• Iindidi ezithile zezivalo zentliziyo ezingezizo
• Intliziyo defibrillator okanye ipacemaker
• Ukufakwa kwendlebe ngaphakathi (cochlear)
• Isifo sezintso okanye i-dialysis (ngekhe ukwazi ukufumana umahluko)
• Kutshanje kubekwe amalungu anganyanisekanga
• Iindidi ezithile ze-vascular stents
• Ukusebenza ngesinyithi kwiphepha elidlulileyo (unokufuna iimvavanyo ukujonga iziqwenga zentsimbi emehlweni akho)

Ngenxa yokuba i-MRI iqulethe iimagnethi ezinamandla, izinto zesinyithi azivumelekanga kwigumbi elinesikena se-MRI:

• Iipeni, iipokotho, kunye neiglasi zamehlo zingabhabha ngaphaya kwegumbi.
• Izinto ezinje ngezacholo, iiwotshi, amakhadi etyala kunye nezinto zokuva zinokonakaliswa.
• Izikhonkwane, izikhonkwane zeenwele, iiziphu zentsimbi, kunye nezinto ezifanayo zesinyithi zinokuyigqwetha imifanekiso.
• Umsebenzi osuswayo wamazinyo kufuneka ukhutshwe ngaphambi nje kokuskena.

Uvavanyo lwe-MRI alubangeli zintlungu. Kuya kufuneka ulale ungashukumi njengoko intshukumo eninzi inokuphazamisa imifanekiso ye-MRI kwaye ibangele iimpazamo.

Itafile inokuba nzima okanye ibanda, kodwa ungacela ingubo okanye umqamelo. Umatshini wenza ingxolo enkulu kunye nengxolo xa kuvuliwe. Unganxiba iiplagi zendlebe ukunceda ukuthintela ingxolo.

I-intercom egumbini ikuvumela ukuba uthethe nomntu nangaliphi na ixesha. Ezinye ii-MRIs zinomabonakude kunye neefowuni ezizodwa onokuzisebenzisa ukunceda ixesha lidlule.

Akukho xesha lokufumana kwakhona, ngaphandle kokuba unikwe iyeza lokuphumla. Emva kokuvavanywa kweMRI, ungabuyela kwindlela otya ngayo yesiqhelo, umsebenzi kunye namayeza.

Unokufuna i-MRI ye-lumbar ukuba unayo:

• Umqolo ophantsi okanye iintlungu zangasese ezingangcoli emva konyango
• Ubuthathaka emlenzeni, ukuba ndindisholo, okanye ezinye iimpawu ezingaphuculiyo okanye ezimbi

Umboneleli wakho unokuyalela i-MRI ye-lumbar ukuba unayo:

• Umqolo obuhlungu kunye nomkhuhlane
• Iziphene zokuzalwa komqolo ongezantsi
• Ukulimala okanye ukwenzakala kumqolo ongezantsi
• Intlungu ebuyela emva kunye nembali okanye iimpawu zomhlaza
• Isifo sokugubhuka
• Iingxaki zokulawula okanye ukukhupha isinyi sakho
• Ukukhutshwa kwediski

Iziphumo eziqhelekileyo zithetha ukuba umqolo wakho kunye neentsholongwane ezikufutshane zikhangeleka zilungile.

Uninzi lwexesha, iziphumo ezingaqhelekanga zibangelwa:

• I-disk ye-Herniated okanye "ityibilika" (lumbar radiculopathy)
• Ukunciphisa ikholamu yomgogodla (i-spinal stenosis)
• Ukugqoka ngokungaqhelekanga emathanjeni kunye ne-cartilage emthonjeni (spondylitis)

Ezinye iziphumo ezingaqhelekanga zinokubangelwa:

• Utshintsho olwenzakalayo ngenxa yobudala
• I-Ankylosing spondylitis, uhlobo lwe-arthritis
• Usulelo lwamathambo
• Isifo seCauda equina
• Ukuqhekeka komqolo osezantsi ngenxa ye-osteoporosis
• Disk ukudumba (idisitis)
• Ithumba lomqolo ithumba
• Ukulimala kwentambo yomqolo
• Ithumba lomqolo
• ISyringomyelia

Thetha nomboneleli wakho malunga nemibuzo kunye neenkxalabo zakho.

I-MRI ayiqulathanga imitha. Khange kubekho ziphumo bezingalindelekanga zichaziweyo ezivela kumazibuthe kunye namaza erediyo.

Kukhuselekile nokuba kwenziwe iMRI ngexesha lokukhulelwa. Akukho ziphumo bezingalindelekanga okanye iingxaki eziqinisekisiweyo.

Uhlobo oluqhelekileyo lokuchasana (idayi) elisetyenzisiweyo yi-gadolinium. Kukhuselekile kakhulu. Ukuphendula okwaliwa kule dayi kunqabile. Nangona kunjalo, i-gadolinium inokuba yingozi kubantu abaneengxaki zezintso abafuna i-dialysis. Ukuba unengxaki yezintso, nceda uxelele umboneleli wakho phambi kovavanyo.

Iimpawu zemagneti ezomeleleyo ezenziwe ngexesha le-MRI zinokubangela ukuba iintliziyo zihambe kunye nezinye izinto zokufakelwa ukuba zingasebenzi ngokunjalo. Inokubangela nezinye iziqwenga zentsimbi ngaphakathi komzimba wakho ukuba zihambe okanye zitshintshe. Ngenxa yezizathu zokhuseleko, nceda ungafiki nantoni na equlathe isinyithi kwigumbi lokuskena.
