Uma umuntu elimele ngesikhathi ezivocavoca, umsebenzi wezempilo uzo-oda i-X-ray. I-MRI ingase idingeke uma inzima. Kodwa-ke, ezinye iziguli zikhathazeke kakhulu kangangokuthi zidinga kakhulu umuntu ongakwazi ukuchaza ngokuningiliziwe ukuthi lolu hlobo lokuhlola luhlanganisani nokuthi yini ezingase ziyilindele.
Ngokuqondakalayo, noma iyiphi inkinga yokunakekelwa kwezempilo ingaholela emizweni yokukhathazeka nokushuba. Kuye ngesimo, ithimba lokunakekela isiguli lingase liqale ngokuthwebula izithombe njenge-X-ray, ukuhlola okungenabuhlungu okuqoqa izithombe zezakhiwo emzimbeni. Uma ulwazi olwengeziwe ludingeka - ikakhulukazi mayelana nezitho zangaphakathi noma izicubu ezithambile - kungase kudingeke i-MRI.
I-MRI, noma i-magnetic resonance imaging, iyindlela yokucabanga yezokwelapha esebenzisa amandla kazibuthe namaza omsakazo ukuze kwakhe izithombe ezinemininingwane yezitho nezicubu emzimbeni.
Abantu bavame ukuba nokungaqondi okuningi nemibuzo lapho bethola i-MRI. Nansi imibuzo emihlanu ephezulu abantu abayibuza cishe nsuku zonke. Sethemba ukuthi lokhu kukusiza ukuthi uqonde ukuthi yini ongayilindela uma unokuhlolwa kwe-radiology.
1. Kuthatha isikhathi esingakanani lokhu?
Kunezizathu eziningi zokuthi kungani ukuhlolwa kwe-MRI kuthatha isikhathi eside kunama-X-ray nama-CT scan. Okokuqala, i-electromagnetism isetshenziselwa ukudala lezi zithombe. Singahamba ngokushesha njengoba imizimba yethu idonsa uzibuthe. Okwesibili, inhloso ukwakha isithombe esihle kakhulu ngangokunokwenzeka, okusho ukuthi isikhathi esiningi ngaphakathi kusithwebuli. Kodwa ukucaca kusho ukuthi izazi ze-radiologists zivame ukukwazi ukubona i-pathology ngokucacile ezithombeni zethu kunasezithombeni ezivela kwezinye izikhungo.
2.Kungani iziguli kufanele zishintshe izingubo zami futhi zisuse ubucwebe bami?
Imishini ye-MRI inozibuthe abakhulu abakhiqiza ukushisa futhi badale insimu enamandla kazibuthe, ngakho-ke kubalulekile ukuthi uphephe. Ozibuthe bangakwazi ukudonsa izinto ezinensimbi, noma lezo eziqukethe insimbi, zingene emshinini ngamandla amakhulu. Lokhu futhi kungabangela umshini ukuthi ujikelezise futhi usonte ngemigqa ye-flux yamazibuthe. Izinto ezingenayo insimbi njenge-aluminiyamu noma ithusi zizokhiqiza ukushisa kanye nje ngaphakathi kusikena, okungase kubangele ukusha. Kube nezimo lapho izingubo zishisiwe. Ukuze sigweme noma yiziphi zalezi zinkinga, sicela zonke iziguli zishintshe zigqoke izingubo ezigunyazwe esibhedlela futhi zisuse bonke ubucwebe nanoma yiziphi izinto ezinjengomakhalekhukhwini, izinsiza-kuzwa nezinye izinto emzimbeni.
3.Udokotela wami uthi ukufakelwa kwami kuphephile. Kungani ulwazi lwami ludingeka?
Ukuqinisekisa ukuphepha kwaso sonke isiguli nochwepheshe, kubalulekile ukwazi ukuthi izinsimbi ezithile, njengezinhliziyo ezishaya inhliziyo, izikhuthazi, iziqeshana, noma amakhoyili, zifakiwe yini emzimbeni. Lawa madivayisi avame ukuza namajeneretha noma amabhethri, ngakho-ke kudingeka isendlalelo esengeziwe sokuvikela ukuze kuqinisekiswe ukuthi akukho ukuphazamiseka emshinini, ikhono lawo lokuthola isithombe esinembe kakhulu, noma ikhono lawo lokukugcina uphephile. Uma sazi ukuthi isiguli sinomshini ofakiwe, kufanele silungise indlela isithwebuli esisebenza ngayo ngokuvumelana neziqondiso zomkhiqizi. Ngokukhethekile, kufanele siqinisekise ukuthi iziguli zingabekwa ngokuphephile ngaphakathi kwesikena esingu-1.5 Tesla (1.5T) noma isikena esingu-3 Tesla (3T). I-Tesla iyiyunithi yokulinganisa yamandla kazibuthe. Izikena ze-MRI ze-Mayo Clinic zitholakala ngamandla angu-1.5T, 3T, kanye nangu-7 Tesla (7T). Odokotela kufanele futhi baqinisekise ukuthi idivayisi ikumodi "ye-MRI ephephile" ngaphambi kokuqala ukuskena. Uma isiguli singena endaweni ye-MRI ngaphandle kokuthatha zonke izinyathelo zokuphepha, izinto zokusebenza zingalimala noma zishise noma ngisho nesiguli singathuka.
4.Yimiphi imijovo, uma ikhona, isiguli esiyoyithola?
Iziguli eziningi zithola imijovo yemidiya yokuqhathanisa, esetshenziselwa ukusiza ukuthuthukisa ukuthwebula izithombe. (Imidiya yokuqhathanisa ivamise ukujovwa emzimbeni wesiguli kusetshenziswa aumjovo wemidiya wokugqama kwengcindezi ephezulu. Izinhlobo zokujova okuhlukile kwemidiya ezivame ukusetshenziswa zifaka phakathiI-CT injector eyodwa, I-CT double head injector, Umjovo we-MRI, futhiI-Angiography ephezulu yomfutho wegazi injector) Imijovo ivamise ukwenziwa ngomjovo futhi ngeke idale ukulimala noma ukusha. Ukwengeza, kuye ngokuhlolwa okwenziwe, ezinye iziguli zingase zithole umjovo womuthi okuthiwa i-glucagon, ozosiza ukubambezela ukunyakaza kwesisu ukuze kuthathwe izithombe ezinembayo.
5. Ngine-claustrophobic. Kuthiwani uma ngizizwa ngingaphephile noma ngingakhululekile phakathi nokuhlolwa?
Kunekhamera ngaphakathi kweshubhu le-MRI ukuze uchwepheshe akwazi ukuqapha isiguli. Ukwengeza, iziguli zigqoka ama-headphone ukuze zizwe imiyalelo futhi zixhumane nochwepheshe. Uma iziguli zizizwa zingakhululekile noma zikhathazekile nganoma isiphi isikhathi phakathi nokuhlolwa, zingakhuluma futhi abasebenzi bazozama ukuzisiza. Ukwengeza, kwezinye iziguli, i-sedation ingasetshenziswa. Uma isiguli singakwazi ukwenza i-MRI, isazi se-radiologist kanye nodokotela odlulisela isiguli bazobonisana ukuze banqume ukuthi okunye ukuhlola kufaneleka kakhulu yini.
6.Kungakhathaliseki ukuthi kusemqoka ukuthi yiluphi uhlobo lwesikhungo oluvakashelwayo ukuze kutholwe isithwebuli se-MRI.
Kunezinhlobo ezahlukene zezikena, ezingahluka ngokwamandla kazibuthe asetshenziselwa ukuqoqa izithombe. Ngokuvamile sisebenzisa izikena ze-1.5T, 3T kanye ne-7T. Kuye ngesidingo sesiguli kanye nengxenye yomzimba ehlolwayo (okungukuthi, ubuchopho, umgogodla, isisu, idolo), isithwebuli esithile singase sifaneleka kangcono ukubuka ngokunembile isimo somzimba wesiguli futhi sinqume ukuxilongwa.

I-LnkMed ingumhlinzeki wemikhiqizo namasevisi emkhakheni we-radiology embonini yezokwelapha. Amasirinji aphakathi nendawo anomfutho ophakeme athuthukiswe futhi akhiqizwa inkampani yethu, okuhlanganisaI-CT injector eyodwa,I-CT double head injector,Umjovo we-MRIfuthiumjovo wemidiya wokuqhathanisa i-angiography, asethengiselwe amayunithi angaba ngu-300 ekhaya naphesheya, futhi azuze ukunconywa ngamakhasimende. Ngasikhathi sinye, i-LnkMed futhi ihlinzeka ngezinaliti ezisekelayo namashubhu afana nezinto ezisetshenziswayo zale mikhiqizo elandelayo: i-Medrad, i-Guerbet, i-Nemoto, njll., kanye namajoyinti okucindezela okuhle, imitshina ye-ferromagnetic neminye imikhiqizo yezokwelapha. I-LnkMed ibilokhu ikholelwa ukuthi ikhwalithi iyisisekelo sentuthuko, futhi ibisebenza kanzima ukuhlinzeka amakhasimende ngemikhiqizo namasevisi asezingeni eliphezulu. Uma ufuna imikhiqizo yokuthwebula yezokwelapha, wamukelekile ukuthintana noma uxoxisane nathi.
