Ukuskena kwe-MRI ehlombe

Ukuskena kwe-MRI (magnetic resonance imaging) ehlombe kuyisivivinyo sokusebenzisa izithombe esisebenzisa amandla avela kumazibuthe anamandla nokwakha izithombe zendawo yehlombe.

Ayisebenzisi imisebe (x-ray).

Izithombe ezi-Single ze-MRI zibizwa ngokuthi izingcezu. Izithombe zingagcinwa kukhompyutha noma ziphrintwe kwifilimu. Isivivinyo esisodwa sikhiqiza inqwaba noma kwesinye isikhathi amakhulu ezithombe.

Ukuhlolwa okuhlobene kufaka phakathi:

• Ingalo ye-MRI
• I-MRI

Ungacelwa ukuthi ugqoke ingubo yasesibhedlela noma okokwembatha ngaphandle kwezicucu zensimbi noma uziphu (njengezikibha zezithukuthuku nesikibha). Qiniseka ukuthi ukhumula iwashi lakho, ubucwebe, nesikhwama semali. Ezinye izinhlobo zensimbi zingadala ukufiphala kwezithombe.

Uzolala etafuleni elincane, elingena kushubhu enkulu efana nomhubhe.

Ezinye izivivinyo zidinga udayi okhethekile (umehluko). Idayi ivame ukunikezwa ngaphambi kokuhlolwa ngomthambo (IV) osesandleni sakho noma engalweni. Idayi nayo ingajovwa ehlombe. 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 udokotela wakho uma wesaba izikhala eziseduze (une-claustrophobia). Unganikezwa umuthi ozokusiza uzizwe ulele futhi ungakhathazeki kakhulu (ukuthambisa). Udokotela wakho futhi angaphakamisa iMRI "evulekile", lapho umshini ungasondelene kakhulu nomzimba.

Ngaphambi kokuhlolwa, tshela umhlinzeki wakho wezokunakekelwa kwempilo uma une:

• 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
• Kusetshenziswe ngensimbi yensimbi esikhathini esedlule (ungadinga ukuhlolwa ukuhlola izingcezu zensimbi emehlweni akho)

Ngoba i-MRI iqukethe odonsa abanamandla, izinto zensimbi azivunyelwe 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 kungadala amaphutha.

Itafula lingaba nzima noma libande, kepha ungacela ingubo noma umcamelo. Umshini ukhiqiza imisindo emikhulu yokuqhuma nokuhayiza lapho uvuliwe. Ungafaka ama-plugs endlebe ukusiza ukunciphisa umsindo.

I-intercom egumbini ikuvumela ukuthi ukhulume nomuntu nganoma yisiphi isikhathi. Amanye ama-MRIs anamathelevishini namahedfoni akhethekile ukukusiza ukuthi udlule isikhathi.

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

I-MRI iyasiza ekuhloleni nasekuhloleni ukulimala kwezemidlalo. Inganikeza izithombe ezicacile zezingxenye zehlombe (njengezicubu ezithambile) okunzima ukuzibona kahle kuma-CT scan.

Umhlinzeki wakho anga-oda lokhu kuhlolwa uma une:

• Ubunzima obungazwakala ngesikhathi sokuhlolwa komzimba
• Ukutholwa okungajwayelekile ku-x-ray noma ukuskena kwethambo
• Ubuhlungu behlombe nomkhuhlane
• Ukuncipha kokuhamba kwehlanganisela yehlombe
• Ukwakhela uketshezi ehlangene ehlombe
• Ububomvu noma ukuvuvukala kokuhlangana kwehlombe
• Ukungazinzi kwamahlombe
• Ubuthakathaka bamahlombe
• Ubuhlungu bamahlombe nomlando womdlavuza
• Ubuhlungu bamahlombe obungabi ngcono ngokwelashwa

Umphumela ojwayelekile usho ukuthi azikho izinkinga ezibonwe ehlombe lakho nezicubu ezizungezile ezithombeni.

Ezinye izimbangela zemiphumela engajwayelekile kungaba:

• Izinguquko ezizenzakalelayo ngenxa yeminyaka
• Ithumba
• Ukutheleleka kwamathambo (i-osteomyelitis)
• Ithambo lehlombe eliphukile noma eliphukile
• I-bursitis endaweni ehlombe
• Izinyembezi zeBiceps
• I-Osteonecrosis engajwayelekile (i-vascular necrosis)
• Isigaxa seRotator siyakhala
• I-Rotator cuff tendinitis
• Ukuvuvukala kwamahlombe (ihlombe elifriziwe)
• I-tumor (kufaka phakathi umdlavuza)
• Izinyembezi zeLabral
• I-cyst ehlombe

Lolu hlu alufaki zonke izinkinga ezingaba khona. Khuluma nomhlinzeki wakho nganoma yimiphi imibuzo nokukhathazeka.

I-MRI ayiqukethe imisebe. Ayikho imiphumela emibi ebangelwe amandla kazibuthe namagagasi omsakazo abikiwe.

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 kulesisithako akuvamile ukwenzeka. 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. Sicela uqiniseke ukuthi awulethi noma yini equkethe insimbi egumbini lesithwebuli, ingaba yi-projectile futhi ibe yingozi kuwe.

Ukuhlolwa okungenziwa esikhundleni se-MRI yehlombe kufaka:

• Ihlombe le-CT scan
• I-X-ray ehlombe

Kungancanyelwa i-CT scan kwezinye izimo eziphuthumayo, ngoba iyashesha futhi imvamisa itholakala ngqo egumbini labezimo eziphuthumayo.
