Iskena seMRI eskena

I-MRI yedolo (imaging resonance imaging) isebenzisa amandla avela kwiimagnethi ezinamandla ukwenza imifanekiso yamadolo kunye nemisipha kunye nezicubu.

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). Nceda ususe iiwotshi zakho, iiglasi, ubucwebe kunye nesipaji. Iindidi ezithile zentsimbi zinokubangela imifanekiso engacacanga.

Uya kulala kwitafile emxinwa ethe tyibilika iskena esikhulu esinjenge-tunnel.

Ezinye iimviwo zisebenzisa idayi ekhethekileyo (umahluko). Uninzi lwexesha, uya kuyifumana idayi nge-vein (IV) engalweni okanye esandleni sakho ngaphambi kovavanyo. Ngamanye amaxesha, idayi itofwa kwilungu. 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. Ingangxola. Ingcali inokukunika iiplagi zeendlebe ukuba ziyafuneka.

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.

Umboneleli wakho unoku-odola olu vavanyo ukuba unayo:

• Iziphumo ezingaqhelekanga kwi-x-ray yedolo okanye ukuskena kwethambo
• Imvakalelo yokuba idolo lakho likhupha edolweni
• Ukwakhiwa kolwelo oludibeneyo emva kwedolo (Baker cyst)
• Ukuqokelela umbane emadolweni
• Usulelo lwexolo elihlangeneyo
• Ukulimala kweKnee cap
• Intlungu yedolo enomkhuhlane
• Ukutshixa amadolo xa uhamba okanye ushukuma
• Iimpawu zomonakalo kwimisipha yamadolo, intlala, okanye iigaments
• Intlungu yedolo engangcono ngonyango
• Ukuzinza kwamadolo

Unokulufumana olu vavanyo lokujonga inkqubela yakho emva kotyando lwedolo.

Iziphumo eziqhelekileyo zithetha ukuba idolo lakho lijongeka lilungile.

Iziphumo ezingaqhelekanga zinokubangelwa kukudinwa okanye ukukrazuka kwemisipha kwindawo yedolo.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Ukonakala okanye utshintsho olwenzeka kubudala
• Ukulimala kwe-Meniscus okanye i-cartilage
• Isifo samathambo emadolweni
• I-Avascular necrosis (ekwabizwa ngokuba yi-osteonecrosis)
• Ithumba okanye umhlaza wamathambo
• Ithambo elaphukileyo
• Ukwakhiwa kolwelo oludibeneyo emva kwedolo (Baker cyst)
• Usulelo kwithambo (i-osteomyelitis)
• Ukudumba
• Ukwenzakala kwekepusi

Thetha nomboneleli wakho ukuba unemibuzo okanye unenkxalabo.

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

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 neentsimbi ezincinci ngaphakathi emzimbeni wakho ukuba zihambe okanye zitshintshe. Ngenxa yezizathu zokhuseleko, nceda ungafiki nantoni na equlathe isinyithi kwigumbi lokuskena.

Uvavanyo olunokwenziwa endaweni ye-MRI yamadolo lubandakanya:

• Ukuvavanywa kwe-CT emadolweni
• I-X-ray yedolo
