Ukuskena umlenze we-MRI

Umlenze we-MRI (imaging resonance imaging) yomlenze usebenzisa oomazibuthe abomeleleyo ukwenza imifanekiso yomlenze. Oku kunokubandakanya iqatha, unyawo, kunye nezicubu ezijikelezileyo.

I-MRI yomlenze nayo yenza imifanekiso yamadolo.

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 kucelwa ukuba unxibe ilokhwe yasesibhedlele okanye iimpahla ngaphandle kweziphu zentsimbi okanye iifoto (ezinje ngezikipa kunye nesikipa). Qiniseka ukuba ukhulula iwotshi yakho, ubucwebe kunye nesipaji. Ezinye iintlobo zentsimbi zinokubangela imifanekiso engacacanga.

Uya kulala kwitafile emxinwa ethe tyibilika iskena esinjenge-tunnel.

Ezinye iimviwo zisebenzisa idayi ekhethekileyo (umahluko). Uninzi lwexesha, uya kuyifumana idayi nge-vein engalweni okanye kwisandla sakho ngaphambi kovavanyo. Ngamanye amaxesha, idayi inikwa ngokudibeneyo. 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 ngephepha lesinyithi (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.

Olu vavanyo lubonelela ngemifanekiso eneenkcukacha yamalungu omlenze ekunzima ukuwabona ngokucacileyo kwizikena ze-CT.

Umboneleli wakho unoku-odola i-MRI yomlenze ukuba unayo:

• Ubunzima obunokuviwa kuvavanyo lomzimba
• Ukufumana okungaqhelekanga kwi-x-ray okanye kwi-scan scan
• Iziphene zokuzalwa zomlenze, iqatha, okanye unyawo
• Intlungu yethambo kunye nomkhuhlane
• Ithambo elaphukileyo
• Ukuncipha kwesindululo selungu leqatha
• Intlungu, ukudumba, okanye bomvu emlenzeni
• Ubomvu okanye ukudumba kwelungu leqatha
• Intlungu yomlenze kunye nembali yomhlaza
• Umlenze, unyawo, okanye iintlungu zamaqatha ezingangcono kunyango
• Ukungazinzi kweqatha neenyawo zakho

Iziphumo eziqhelekileyo zithetha ukuba umlenze wakho ubonakala ulungile.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Utshintsho olwenzakalayo ngenxa yobudala
• Ithumba
• I-tendonitis yama-Achilles
• Isifo samathambo
• Ithambo elaphukileyo okanye ukwaphuka
• Usulelo kwithambo
• I-Ligament, i-tendon, okanye ukulimala kwe-cartilage
• Ukonakala kwemisipha
• I-Osteonecrosis (i-avascular necrosis)
• Ukuqhekeka kwePlantar fascia (Jonga: Plantar fascitis)
• Ukungasebenzi kakuhle kwethoni ye-tibial tendon
• Ukulila okanye ukuqhekeka kwethoni ye-Achilles kwindawo yeqatha
• Ithumba okanye umhlaza kwithambo, izihlunu, okanye izicwili ezithambileyo

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 ngokuchaseneyo 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.

Uvavanyo olunokwenziwa endaweni ye-MRI lubandakanya:

• Ukuskena amathambo
• Ukuhlolwa kwe-CT komlenze
• Ukuskena i-Positron emission tomography (PET)
• X-reyi yomlenze

I-CT scan inokukhethwa kwimeko engxamisekileyo. Uvavanyo luyakhawuleza kune-MRI kwaye ihlala ifumaneka kwigumbi likaxakeka.
