Ukuskena Umlenze we-MRI

Umlenze we-MRI (magnetic resonance imaging) womlenze usebenzisa ozibuthe abanamandla ukwakha izithombe zomlenze. Lokhu kungafaka iqakala, unyawo, nezicubu ezizungezile.

I-MRI yomlenze nayo idala izithombe zamadolo.

I-MRI ayisebenzisi imisebe (x-ray).

Izithombe ezi-Single ze-MRI zibizwa ngokuthi izingcezu. Izithombe zingagcinwa kukhompyutha noma ziphrintwe kwifilimu. Isivivinyo esisodwa sikhiqiza izithombe eziningi.

Uzocelwa ukuthi ugqoke ingubo yasesibhedlela noma izingubo ezingenaziphu zensimbi noma izifinyezo (njengezikibha zokujuluka nesikibha). Qiniseka ukuthi ukhumula iwashi lakho, ubucwebe nesikhwama semali. Ezinye izinhlobo zensimbi zingadala ukufiphala kwezithombe.

Uzolala etafuleni elincane elingena kuskena esifana nomhubhe.

Ezinye izivivinyo zisebenzisa udayi okhethekile (umehluko). Isikhathi esiningi, uzothola udayi ngomthambo engalweni noma esandleni sakho ngaphambi kokuhlolwa. Kwesinye isikhathi, udayi unikezwa esihlangwini. Idayi isiza udokotela we-radiologist ukuthi abone izindawo ezithile ngokucace kakhudlwana.

Ngesikhathi seMRI, umuntu osebenzisa umshini uzokubuka ukwelinye igumbi. Ukuhlolwa kuvame ukuthatha imizuzu engama-30 kuye kwangama-60, kepha kungathatha isikhathi eside.

Ungacelwa ukuthi ungadli noma uphuze noma yini amahora amane kuya kwayisithupha ngaphambi kokuskena.

Tshela umhlinzeki wakho wezokunakekelwa kwezempilo uma wesaba izindawo ezivaliwe (une-claustrophobia). Unganikezwa umuthi ozokusiza uzizwe ulele futhi ungakhathazeki kangako. Umhlinzeki wakho angaphakamisa i-MRI "evulekile", lapho umshini ungasondelene kakhulu nomzimba.

Ngaphambi kokuhlolwa, tshela umhlinzeki wakho uma ngabe:

• Iziqeshana ze-aneurysm zobuchopho
• Izinhlobo ezithile zamavalvu enhliziyo yokufakelwa
• Inhliziyo defibrillator noma i-pacemaker
• Ukufakwa kwendlebe kwangaphakathi (cochlear)
• Isifo sezinso noma i-dialysis (ungahle ungakwazi ukuthola umehluko)
• Amalunga wokufakelwa asanda kufakwa
• Izinhlobo ezithile ze-vascular stents
• Kusetshenzwe ngensimbi eshidi (ungadinga izivivinyo ukubheka izingcezu zensimbi emehlweni akho)

Ngoba i-MRI iqukethe odonsa abanamandla, izinto zensimbi azivunyelwe ukungena egumbini elinesithwebuli se-MRI:

• Amapeni, okhiye bokuphaka, nezibuko zamehlo zingandiza zinqamule igumbi.
• Izinto ezinjengobucwebe, amawashi, amakhadi esikweletu nezinsiza-kuzwa zingalimala.
• Izikhonkwane, okokufaka izinwele, uziphu wensimbi, nezinto ezifanayo zensimbi kungasonta izithombe.
• Umsebenzi wamazinyo osusekayo kufanele ukhishwe ngaphambi nje kokuskena.

Ukuhlolwa kwe-MRI akubangeli buhlungu. Uzodinga ukuqamba amanga unganyakazi. Ukunyakaza okuningi kungafiphaza izithombe ze-MRI futhi kudale amaphutha.

Itafula lingaba nzima noma libande, kepha ungacela ingubo noma umcamelo. Umshini wenza umsindo omkhulu wokuduma nokuhayiza lapho uvuliwe. Ungafaka ama-plugs endlebe ukusiza ukuvimba umsindo.

I-intercom egumbini ikuvumela ukuba ukhulume nomuntu nganoma yisiphi isikhathi. Amanye ama-MRIs anamathelevishini namahedfoni akhethekile okusiza ukuhamba kwesikhathi.

Asikho isikhathi sokululama, ngaphandle kokuthi unikwe umuthi wokuphumula. Ngemuva kokuskena kwe-MRI, ungabuyela ekudleni kwakho okujwayelekile, emsebenzini, nasemithini.

Lokhu kuhlolwa kunikeza izithombe eziningiliziwe zezingxenye zomlenze okunzima ukuzibona ngokucacile kuzikena ze-CT.

Umhlinzeki wakho anga-oda i-MRI yomlenze uma une:

• Ubunzima obungazwakala ekuhlolweni komzimba
• Ukutholwa okungajwayelekile ku-x-ray noma ukuskena kwethambo
• Ukukhubazeka kokuzalwa komlenze, iqakala, noma unyawo
• Ubuhlungu bamathambo nomkhuhlane
• Ithambo eliphukile
• Ukuncipha kokuhamba kwejoyini leqakala
• Ubuhlungu, ukuvuvukala, noma ubomvu emlenzeni
• Ukubomvu noma ukuvuvukala kwenhlanganisela yamaqakala
• Ubuhlungu bomlenze nomlando womdlavuza
• Ubuhlungu bomlenze, bonyawo, noma beqakala obungabi ngcono ngokwelashwa
• Ukuntengantenga kweqakala nezinyawo zakho

Umphumela ojwayelekile usho ukuthi umlenze wakho ubukeka KULUNGILE.

Imiphumela engajwayelekile ingabangelwa:

• Izinguquko ezizenzakalelayo ngenxa yeminyaka
• Ithumba
• I-Achilles tendonitis
• Isifo samathambo
• Ithambo eliphukile noma ukuphuka
• Ukutheleleka ethanjeni
• Ukulimala kwe-ligament, tendon, noma ye-cartilage
• Ukulimala kwemisipha
• I-Osteonecrosis (i-avascular necrosis)
• Ukuqhekeka kwePlantar fascia (Bheka: Plantar fascitis)
• Ukungasebenzi kahle kwetonial tibial tendon
• Izinyembezi noma ukuqhekeka kwethenda le-Achilles endaweni yeqakala
• Isimila noma umdlavuza ethanjeni, emisipheni noma ezicutshini ezithambile

Khuluma nomhlinzeki wakho ngemibuzo yakho nokukhathazeka kwakho.

I-MRI ayiqukethe imisebe. Akubanga khona miphumela emibi ebikiwe evela kumandla kazibuthe namagagasi omsakazo.

Kuphephile futhi ukuthi kwenziwe i-MRI ngesikhathi sokukhulelwa. Ayikho imiphumela emibi noma izinkinga eziye zafakazelwa.

Uhlobo oluvame kakhulu lokuqhathanisa (udayi) olusetshenzisiwe yi-gadolinium. Kuphephe kakhulu. Ukusabela okweqile kungavamile. Kodwa-ke, i-gadolinium ingaba yingozi kubantu abanezinkinga zezinso ezidinga i-dialysis. Uma unezinkinga zezinso, sicela utshele umhlinzeki wakho ngaphambi kokuhlolwa.

Amandla kazibuthe aqinile adalwe ngesikhathi seMRI angadala ukuthi izinhliziyo zisebenze futhi nezinye izinto zokufakelwa zingasebenzi. Kungadala nokuthi ucezu lwensimbi ngaphakathi komzimba wakho luhambe noma lushintshe. Ngezizathu zokuphepha, ngicela ungalethi noma yini equkethe insimbi egumbini lesithwebuli.

Ukuhlolwa okungenziwa esikhundleni se-MRI kufaka:

• Ukuskena kwamathambo
• I-CT scan yomlenze
• Ukuskena kwePositron emission tomography (PET)
• I-X-ray yomlenze

Kungancanyelwa i-CT scan esimeni esiphuthumayo. Ukuhlolwa kuyashesha kune-MRI futhi kuvame ukutholakala egumbini labezimo eziphuthumayo.
