Uma umuntu elimele ngesikhathi evivinya umzimba, udokotela wakhe uzoyalela i-X-ray. Kungadingeka i-MRI uma inzima kakhulu. Kodwa-ke, ezinye iziguli zikhathazekile kangangokuthi zidinga kakhulu umuntu ongachaza ngokuningiliziwe ukuthi lolu hlobo lokuhlolwa luhilelani nokuthi yini ezingayilindela.
Kuyaqondakala ukuthi noma iyiphi inkinga yokunakekelwa kwempilo ingaholela emizweni yokukhathazeka nokucindezeleka. Kuye ngesimo, ithimba lokunakekelwa kwesiguli lingase liqale ngokuskena izithombe njenge-X-ray, ukuhlolwa okungenabuhlungu okuqoqa izithombe zezakhiwo emzimbeni. Uma kudingeka ulwazi olwengeziwe - ikakhulukazi ngezitho zangaphakathi noma izicubu ezithambile - kungadingeka i-MRI.
I-MRI, noma i-magnetic resonance imaging, iyindlela yokuthwebula izithombe yezokwelapha esebenzisa amasimu kazibuthe namagagasi omsakazo ukudala izithombe ezinemininingwane yezitho nezicubu emzimbeni.
Abantu bavame ukuba nokungaqondi kahle okuningi nemibuzo lapho bethola i-MRI. Nansi imibuzo emihlanu ephezulu abantu abayibuza cishe nsuku zonke. Ngethemba ukuthi lokhu kuzokusiza uqonde ukuthi yini ongayilindela uma une-X-ray test.
1. Kuthatha isikhathi esingakanani lokhu?
Kunezizathu eziningi ezenza ukuthi ukuhlolwa kwe-MRI kuthathe isikhathi eside kune-X-ray kanye ne-CT scan. Okokuqala, i-electromagnetism isetshenziswa ukudala lezi zithombe. Singahamba ngokushesha kuphela uma imizimba yethu ixhunywe ku-magnet. Okwesibili, inhloso ukudala isithombe esingcono kakhulu, okusho ukuthi empeleni isikhathi esiningi ngaphakathi kwe-scanner. Kodwa ukucaca kusho ukuthi odokotela be-radiology bavame ukukwazi ukubona izifo ngokucacile ezithombeni zethu kunasezithombeni ezivela kwezinye izikhungo.
2. Kungani iziguli kufanele zishintshe izingubo zami futhi zikhumule ubucwebe bami?
Imishini ye-MRI inamamagnethi aqhuba ukushisa futhi adale insimu yamagnetic enamandla kakhulu, ngakho-ke kubalulekile ukuphepha. Amamagnethi angadonsa izinto ze-ferrous, noma lezo ezinensimbi, emshinini ngamandla amakhulu. Lokhu kungabangela nokuthi umshini ujikeleze futhi usonteke ngemigqa yokuxhuma kwamamagnethi. Izinto ezingezona i-ferrous njenge-aluminium noma ithusi zizokhiqiza ukushisa uma sezingaphakathi kwesikena, okungase kubangele ukusha. Kube nezimo lapho izingubo zishisiwe khona. Ukuze sivimbele noma yiziphi zalezi zinkinga, sicela zonke iziguli ukuthi zishintshe izingubo ezivunyelwe esibhedlela futhi zisuse zonke izinto zokuhloba nanoma yiziphi izinto ezifana namaselula, izinsiza zokuzwa nezinye izinto emzimbeni.
3. Udokotela wami uthi i-implant yami iphephile. Kungani kudingeka ulwazi lwami?
Ukuqinisekisa ukuphepha kwesiguli ngasinye kanye nochwepheshe, kubalulekile ukwazi ukuthi ngabe amadivayisi athile, njenge-pacemakers, izikhuthazi, ama-clip, noma ama-coil, afakwe emzimbeni. Lawa madivayisi avame ukuza nama-generator noma amabhethri, ngakho-ke kudingeka ungqimba olwengeziwe lokuphepha ukuqinisekisa ukuthi akukho ukuphazamiseka emshinini, ikhono lawo lokuthola isithombe esinembile kakhulu, noma ikhono lawo lokukugcina uphephile. Uma sazi ukuthi isiguli sinedivayisi efakwe, kumelwe silungise indlela esebenza ngayo isikena ngokweziqondiso zomenzi. Ngokukhethekile, kumelwe siqinisekise ukuthi iziguli zingafakwa ngokuphephile ngaphakathi kwesikena se-1.5 Tesla (1.5T) noma isikena se-3 Tesla (3T). I-Tesla iyiyunithi yokulinganisa amandla ensimu yamagnetic. Izikena ze-MRI ze-Mayo Clinic zitholakala ngamandla e-1.5T, 3T, kanye ne-7 Tesla (7T). Odokotela kumele futhi baqinisekise ukuthi idivayisi ikwimodi "ephephile ye-MRI" ngaphambi kokuqala ukuskena. Uma isiguli singena endaweni ye-MRI ngaphandle kokuthatha zonke izinyathelo zokuphepha, imishini ingase yonakale noma kungenzeka ukusha noma ngisho nesiguli singase sishaqeke.
4. Yimiphi imijovo, uma ikhona, isiguli esizoyithola?
Iziguli eziningi zithola imijovo ye-contrast media, esetshenziselwa ukuthuthukisa izithombe. (I-contrast media ivame ukufakwa emzimbeni wesiguli kusetshenziswa i-i-injector yemidiya yokungafani enomfutho ophezuluIzinhlobo ezivame ukusetshenziswa njenge-contrast media injector zifaka phakathiUmjovo owodwa we-CT, Umjovo wekhanda eliphindwe kabili we-CT, Umjovo we-MRI, futhiI-Angiography yokucindezela okuphezulu) Imijovo ivame ukwenziwa ngemithambo yegazi futhi ngeke ibangele ukulimala noma ukusha. Ngaphezu kwalokho, kuye ngokuhlolwa okwenziwe, ezinye iziguli zingase zithole umjovo womuthi obizwa ngokuthi i-glucagon, ozosiza ekunciphiseni ukunyakaza kwesisu ukuze kuthathwe izithombe ezinembe kakhudlwana.
5. Nginolaka oluqinile. Kuthiwani uma ngizizwa ngingaphephile noma ngingakhululekile ngesikhathi sokuhlolwa?
Kukhona ikhamera ngaphakathi kwepayipi le-MRI ukuze uchwepheshe akwazi ukuqapha isiguli. Ngaphezu kwalokho, iziguli zigqoka ama-headphone ukuze zizwe imiyalelo futhi zixhumane nochwepheshe. Uma iziguli zizizwa zingakhululekile noma zikhathazekile nganoma yisiphi isikhathi ngesikhathi sokuhlolwa, zingakhuluma futhi abasebenzi bazozama ukuzisiza. Ngaphezu kwalokho, kwezinye iziguli, kungasetshenziswa umuthi wokudambisa ubuhlungu. Uma isiguli singakwazi ukwenza i-MRI, udokotela we-radiologist kanye nodokotela oqondisa isiguli bazobonisana ukuze banqume ukuthi olunye ukuhlolwa lufaneleka yini.
6.Kubalulekile ukuthi uhlobo luni lwesikhungo oluvakashelwa ukuze kutholakale i-MRI scan.
Kunezinhlobo ezahlukene zezikena, ezingahluka ngokuya ngamandla kazibuthe asetshenziswa ukuqoqa izithombe. Ngokuvamile sisebenzisa izikena ze-1.5T, 3T kanye ne-7T. Kuye ngesidingo sesiguli kanye nengxenye yomzimba eskenwayo (okungukuthi, ubuchopho, umgogodla, isisu, idolo), isikena esithile singase sifaneleke kangcono ukubuka ngokunembile ukwakheka komzimba wesiguli nokunquma ukuxilongwa.

I-LnkMed ingumhlinzeki wemikhiqizo nezinsizakalo zensimu ye-radiology embonini yezokwelapha. Amasirinji aphakathi nendawo anomfutho ophezulu athuthukiswe futhi akhiqizwa yinkampani yethu, okuhlanganisaUmjovo owodwa we-CT,Umjovo wekhanda eliphindwe kabili we-CT,Umjovo we-MRIfuthii-angiography contrast media injector, ithengiswe kumayunithi angaba ngu-300 ekhaya nakwamanye amazwe, futhi ithole udumo kumakhasimende. Ngesikhathi esifanayo, i-LnkMed iphinde inikeze izinaliti namapayipi asekelayo njengezinto ezisetshenziswayo zemikhiqizo elandelayo: i-Medrad, i-Guerbet, i-Nemoto, njll., kanye namajoyinti okucindezela amahle, ama-ferromagnetic detectors kanye neminye imikhiqizo yezokwelapha. I-LnkMed ibilokhu ikholelwa ukuthi ikhwalithi iyinsika yentuthuko, futhi ibilokhu isebenza kanzima ukuhlinzeka amakhasimende ngemikhiqizo nezinsizakalo ezisezingeni eliphezulu. Uma ufuna imikhiqizo yezithombe zezokwelapha, wamukelekile ukubonisana noma ukuxoxisana nathi.
