Iskena seMRI yomlomo wesibeleko

Iskena seMRI yomlomo wesibeleko (imaging resonance imaging) sisebenzisa amandla avela kumazibuthe aqinileyo ukwenza imifanekiso yenxalenye yomqolo obaleka entanyeni (umqolo wesibeleko).

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.

Uya kunxiba ilokhwe yasesibhedlele okanye iimpahla ezingenaziphu zentsimbi okanye ii-snaps (ezinje ngezikipa kunye nesikipa). Qiniseka ukuba ukhulula iwotshi yakho, ubucwebe kunye nesipaji. Ezinye iintlobo zentsimbi zinokubangela imifanekiso engacacanga.

Uya kulala kwitafile emxinwa esilayida kwiskena esimile okwe tonela.

Ezinye iimviwo zisebenzisa idayi ekhethekileyo (umahluko). Uninzi lwexesha, uya kuyifumana idayi nge-vein engalweni okanye kwisandla sakho ngaphambi kovavanyo. Idayi inokunikwa 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 uxoke. Ukuhamba kakhulu kunokuphazamisa imifanekiso ye-MRI kwaye kubangele 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 ukunceda ixesha lidlule.

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

Izizathu eziqhelekileyo zolu vavanyo zi:

• Intamo ebukhali, igxalaba, okanye iintlungu zengalo ezingangcono emva konyango
• Intlungu yentamo kunye nobuthathaka emlenzeni, ukuba ndindisholo, okanye ezinye iimpawu

Iskena se-MRI somlomo wesibeleko sinokwenziwa:

• Iziphene zokuzalwa komqolo
• Usulelo olubandakanya umqolo wakho
• Ukonzakala okanye ukwenzakala emqolo
• Isifo sokugubhuka
• I-scoliosis enamandla
• Ithumba okanye umhlaza emqolo
• Isifo samathambo emqolo

I-MRI isebenza ngcono kune-CT scan ekuchongeni ezi ngxaki amaxesha amaninzi.

I-MRI yomlomo wesibeleko nayo inokwenziwa ngaphambi kotyando lomqolo.

Iziphumo eziqhelekileyo zithetha ukuba inxalenye yomqolo ohamba entanyeni yakho kunye neentsholongwane ezikufutshane zibonakala ziqhelekileyo.

Izizathu eziqhelekileyo zesiphumo esingaqhelekanga zezi:

• I-Herniated okanye "ityibilika" idiski (i-radiculopathy yomlomo wesibeleko)
• Ukunciphisa umlenze wesibeleko (spinal stenosis)
• Ukugqoka okungaqhelekanga kwamathambo kunye ne-cartilage entanyeni (i-spondylosis yomlomo wesibeleko)

Iziphumo ezingaqhelekanga zinokubangelwa:

• Utshintsho olwenzakalayo ngenxa yobudala
• Usulelo lwe-Bone (osteomyelitis)
• Disk ukudumba (idisitis)
• Usulelo lomqolo
• Isifo sokugubhuka
• Ukulimala kwentambo yomqolo okanye uxinzelelo
• Ukuqhekeka komqolo
• Ithumba lomqolo

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 ngokuchasene nezinto ezithile 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 ukuba iqhekeza lesinyithi ngaphakathi emzimbeni wakho lihambe okanye litshintshe. Ngenxa yezizathu zokhuseleko, nceda ungafiki nantoni na equlathe isinyithi kwigumbi lokuskena.
