Izivivinyo ze-imagination ze-magnontic resonance (MRIs) zivame ukusetshenziswa ngabahlinzeki bama-orthopedic ukuhlola izimo ezihlukahlukene. I-MRIs ingaba usizo ngokukhethekile ekuhlinzekeni isithombe esibukwayo samathambo ahlukene emzimbeni. Ngokuvumela udokotela wakho ukuba 'abone' izicubu ezibandakanya imisipha, ithethoni, i-cartilage, ithambo, kanye nemigqa, ukulimala kwesakhiwo esimisweni se-musculoskelet kungahlolwa.
I-MRIs isetshenziselwa ukukhomba izinyembezi ze -Rotator ezinhlathini, ukulimala kwe-ligament emhlane, kanye nezinye izimo ezihlukahlukene zomzimba emzimbeni wonke. Ngenkathi i- MRIs ingase ingabi yilingo oluhle kuzo zonke izilungiselelo zemitholampilo, iyilingo eliwusizo elingasetshenziswa ukuhlola izimo ezihlukahlukene.
Kunezimo lapho i-MRI ingenziwa khona okuthiwa "ukuthuthukiswa okuhlukile." Ukuqhathaniswa kuyinto engabekwa ngayo ezindaweni ezihlukahlukene zomzimba ukuze zibonakale nakakhulu ngokuskena. Isibonelo, ngezinye izikhathi ukuqhathaniswa kujojelwa egazini ukuze kusetshenziswe kangcono indawo yemithambo yegazi ku-MRI. Ukungafani kungabuye kujowe ngaphakathi kokubambisana ukuze kusize ukutholwa kwamagundane angaphezu kwezicathulo kanye nokulimala kwe-cartilage. Nokho, ngalezi zinqubo, umbuzo uvame ukubuza: Ingabe ukuhlukana kwezixazululo kuphephile?
Ukuthuthukiswa kwe-Gadolinium
I-ejenti evame ukusetshenziswa kakhulu yokuhlolwa kwe-MRI ibizwa ngokuthi i-gadolinium.
I-Gadolinium iyinsimbi yenhlabathi engavamile engasetshenziselwa izilungiselelo zokunakekelwa kwezempilo ukugqamisa ukutholakala okuqondile ekuhlolweni kwe-MRI. Inani elincane le-gadolinium lingafakwa egameni legazi noma lijozwe libe yingxenye ukuze linikeze ukuthuthukiswa okuhlukile kokuya kwe-MRI. Amanye ama-agent wokuphambene asetshenziselwa ezinye izinhlobo zokuhlolwa kwe-imaging.
Isibonelo, abantu abane-X-ray noma i-CT scans bavame ukuba nama-contrast agents, kodwa lokhu akusiyo igadolinium esekelwe. Ezingxenyeni eziningi ze-radiographic, umehluko i-iodine-based.
Ngezimo zamathambo, uhlobo oluvame kakhulu lokusebenzisa ukuthuthukiswa okungafani nalo lubizwa ngokuthi i-MRI gadolinium i-arthrography eyathuthukisiwe. Lokhu kusho ukuthi isixazululo sokuphambene, i-gadolinium, sijojowe ngaphakathi kwe-joint. Ngokujova ukungafani phakathi kokujoyina, kuba lula ukubona ngeso lengqondo umonakalo we-cartilage kanye nemigudu. Ukuthuthukiswa kokungafani kungasetshenziswa ezinhlobonhlobo eziningi zama-MRIs, kodwa izizathu ezivame kakhulu zokuthola i-MRI ehambelanisiwe ihlanganisa:
- I-MRIs enamahlombe ukuhlola ukuthi kungenzeka yini izinyembezi ezinzima
- I-MRIs ka-Elbow ukuhlola ukulimala kwe " Tommy John "
- Ama-MRI ama-Hip ahlolisise izinyembezi ze- labral
Njengoba kukhonjisiwe, ukuthuthukiswa okuhlukile kungasetshenziselwa ezinye izizathu, lezi ezinye zezizathu ezivame kakhulu ukuthi kungani ohlinzayo wakho wamazinyo angase acele ukuhlolwa ukuze kuqhathaniswe ngcono.
Ingabe Ukungafani Kuphephile?
Kube nesithakazelo sakamuva kuphephelo lwe-gadolinium efakwe emzimbeni. Iningi locwaningo oluphathelene nombuzo luhlobene nomjovo we-gadolinium engxenyeni yegazi, ngakho-ke kukhona idatha encane kakhulu ebheka ukuphepha komjovo we-gadolinium engxenyeni.
Ukukhathazeka ngomjovo egameni legazi ukuthi i-gadolinium ingakwazi ukuqoqa futhi iqhubeke emathisini athile omzimba. Kubuye kube nokuhlangana ne-gadolinium okubangela ukugula kwesifo sezinso kubantu abathile. Ngalokhu lokhu akuwona ohlangothini oluvamile, kuphakamisa amathuba okukhathazeka.
Ucwaningo oluningi lubonise ukuthi i-gadolinium iyisisetshenziswa esiphephile sokusebenzisa, ngisho nangesikhathi sokukhulelwa. Uma nje abantu bengenayo isifo se-kidney esebenzayo, ama-injection ye-gadolinium abhekwa njengophephile. Nakuba lesi sici akufanele sisetshenziswe njalo, kungaba yithuluzi eliwusizo lokusiza ukuhlonza izimo ezihlukahlukene.
Kukhona nezinye izifundo zocwaningo ezibonisa ubufakazi bokuthi imishanguzo ye-gadolinium engxenyeni ingabangela ukuvuvukala okuhlangene nokucasula. Akucaci ukuthi i-gadolinium iyona yeso sizathu, futhi isizathu sokuthi abantu bathole ukuvuvukala okuhambisanayo ngemva kwale mijovo kungase kube umphumela wevolumu yetshezi ephethwe, noma ezinye izinto ezijojowe kanye ne-gadolinium. Kodwa-ke, ukuba nomjovo, kungakhathaliseki ukuthi kuyini imbangela, kungabangela izimpawu ezengeziwe zokuhlukunyezwa.
Ingabe Kunesidingo Sokungafani Kokuhlukile?
Kungenzeka ukuthi umbuzo omkhulu: Ingabe i-gadolinium arthrography iyadingeka ukuze kutholakale izinyembezi noma ukulimala kukaTommy John? Le mpikiswano engezansi, futhi iyinto eguqukayo njengoba i-MRIs ithuthuka ngekhwalithi yabo. Akungabazeki ukuthi i-MRIs eyenziwe ngokungafani nayo isetshenziselwa ukusebenza ngokuphumelelayo ekwenzeni ukuxilongwa kwezinhlobo ezithile zokulimala kunama-MRIs angenayo. Kodwa-ke, i-MRIs ithola ngokunembile kakhulu, futhi umehluko phakathi kokuthuthukiswa okungafaniyo kanye ne-MRI engenayo i-non-IRR kungenzeka ukuthi ingabi yinto ephawulekayo njengoba yayisetshenziswa. Kukhona idatha emisha ebonisa ukuthuthukiswa okungafaniyo akudingekile ukuba wenze izifo eziningi ezijwayelekile zomuthi wezinzwa.
Okufanele ngikwenze?
Uma udokotela wakho ephakamisa i-MRI ehlukisiwe, kunengqondo ukubabuza uma ukuthuthukiswa okuhlukile kuqakathekile ngempela. Njengoba kukhonjisiwe, ngemishini emisha ye-MRI ehlinzeka ngezithombe ezingcono zekhwalithi, isidingo sokuthuthukiswa okungafani kwe-intra-articular siyaba yinto encane kakhulu. Kunezikhathi ezingangabazeki lapho ukwenziwa ngcono kokuqhathaniswa kuyindlela engcono, kodwa lokhu kungavamile kakhulu futhi iningi lezinhlolo ze-MRI lingafezwa ngaphandle kokuthuthukiswa okungafani.
Abantu abanezinkinga ezingaphansi kwezinso kufanele baqinisekise ukuthi udokotela wabo uyazi ngalolu daba ngaphambi kokuba ahlole noma yikuphi ukuhlolwa kwe-MRI. Ngaphezu kwalokho, kunengqondo ukubuza udokotela wakho lokho okuzuzisa ukuhlolwa kwe-MRI-kuqhathaniswa nokuhlolwa okungenakuqhathaniswa kwe-MRI-kungaba. Uma ngabe umehluko awuncane, ungase uthande ukucabangela ukungenwa igadolinium emzimbeni wakho.
Izwi elivela
Imishanguzo yokungafani ingasiza kwezinye i-MRIs ukuba zibenze ngokunembile ukuze zihlolwe izimo ezithile. Kodwa-ke, kunezingozi ezingenzeka ezihlotshaniswa nezinto zokuphambene, futhi ezinye zalezi zingozi zingase zingaqondwa ngokuphelele. Uma kunconywa ukuthuthukiswa okuhlukile, kufanele kwacaca kokubili udokotela wakho nokuthi kungani ingozi eyengeziwe inika inzuzo eyanele. Uma kungekho isizathu esicacile sokusebenzisa ukuthuthukiswa okuhlukile, ama-MRIs amaningi anamuhla angahlola ngokunembile izimo eziningi zemithi ngaphandle kwalengozi engeziwe.
