Uma siya esibhedlela, udokotela uzosinika izivivinyo zokuthwebula izithombe ngokwesidingo sesimo, njenge-MRI, i-CT, ifilimu ye-X-ray noma i-Ultrasound. I-MRI, i-magnetic resonance imaging, ebizwa ngokuthi “i-nuclear magnetic”, ake sibone ukuthi yini abantu abavamile okudingeka bayazi nge-MRI.
Ingabe kukhona imisebe ku-MRI?
Njengamanje, i-MRI iyona kuphela umnyango we-radiology ongenazo izinto zokuhlolwa kwemisebe, asebekhulile, izingane kanye nabesifazane abakhulelwe abangakwenza. Nakuba i-X-ray ne-CT kwaziwa ukuthi zinemisebe, i-MRI iphephile uma kuqhathaniswa.
Kungani ngingakwazi ukuthwala izinto zensimbi nezikazibuthe emzimbeni wami ngesikhathi se-MRI?
Umzimba oyinhloko womshini we-MRI ungafaniswa nozibuthe omkhulu. Kungakhathaliseki ukuthi umshini uvuliwe noma cha, insimu enkulu kazibuthe kanye namandla amakhulu kazibuthe omshini kuzohlala kukhona. Zonke izinto zensimbi eziqukethe insimbi, njengeziqeshana zezinwele, izinhlamvu zemali, amabhande, amaphini, amawashi, imigexo, amacici kanye nobunye ubucwebe nezingubo, kulula ukuzimunca. Izinto zikazibuthe, njengamakhadi kazibuthe, amakhadi e-IC, ama-pacemaker, i-hearing AIDS, omakhalekhukhwini kanye namanye amadivayisi kagesi, zifakwa kalula kuzibuthe noma zonakale. Ngakho-ke, abanye abantu abahambisanayo kanye namalungu omndeni akumele bangene egumbini lokuskena ngaphandle kwemvume yabasebenzi bezokwelapha; Uma isiguli kumele sihambisane nomphelezeli, kufanele kuvunyelwane ngabasebenzi bezokwelapha futhi kulungiselelwe ngokwezidingo zabasebenzi bezokwelapha, njengokungalethi omakhalekhukhwini, okhiye, izikhwama zemali kanye namadivayisi kagesi egumbini lokuskena.
Izinto zensimbi nezinto ezisebenza ngogesi ezimuncwe yimishini ye-MRI zizoba nemiphumela emibi kakhulu: okokuqala, ikhwalithi yesithombe izothinteka kakhulu, kanti okwesibili, umzimba womuntu uzolimala kalula futhi umshini uzolimala ngesikhathi senqubo yokuhlola. Uma ukufakwa kwensimbi emzimbeni womuntu kungeniswa ensimini yamagnetic, insimu enamandla yamagnetic ingenza izinga lokushisa lokufakelwa lenyuke, lishise kakhulu futhi lonakale, futhi indawo yokufakelwa emzimbeni wesiguli ingashintsha, futhi iholele ngisho namazinga ahlukene okusha endaweni yokufakelwa kwesiguli, okungaba kubi njengokusha kwezinga lesithathu.
Ingabe i-MRI ingenziwa ngamazinyo okufakelwa?
Abantu abaningi abanamazinyo okufakelwa bakhathazeka ngokungakwazi ukuthola i-MRI, ikakhulukazi abantu asebekhulile. Eqinisweni, kunezinhlobo eziningi zamazinyo okufakelwa, njengemazinyo okufakelwa aqinile kanye namazinyo okufakelwa ashukumayo. Uma izinto zokufakelwa amazinyo zingeyona i-alloy yensimbi noma ye-titanium, azinawo umthelela omkhulu kwi-MRI. Uma amazinyo okufakelwa equkethe izingxenye zensimbi noma ze-magnetic, kungcono ukususa amazinyo okufakelwa asebenzayo kuqala, ngoba kulula ukuhamba ensimini yamagnetic futhi kuthinte ikhwalithi yokuhlolwa, okuzoba yingozi nasekuphepheni kweziguli; Uma kuyi-denture egxilile, ungakhathazeki kakhulu, ngoba amazinyo okufakelwa aqinile ngokwawo ngeke anyakaze, izinto ezitholakalayo zincane kakhulu. Isibonelo, ukwenza i-MRI yobuchopho, amazinyo okufakelwa aqinile anomthelela othile kuphela efilimini (okungukuthi, isithombe) esithathwe, futhi umthelela mncane kakhulu, ngokuvamile awuthinti ukuxilongwa. Kodwa-ke, uma ingxenye yokuhlolwa isendaweni yamazinyo okufakelwa, isenomthelela omkhulu efilimini, futhi lesi simo sincane, futhi abasebenzi bezokwelapha kudingeka baxoxwe endaweni yesehlakalo. Ungayeki ukudla ngenxa yokwesaba ukuminza, ngoba awukwenzi i-MRI ngoba unezitho zokufakelwa ezilungisiwe.
Kungani ngizizwa ngishisa futhi ngijuluka ngesikhathi se-MRI?
Njengoba sonke sazi, omakhalekhukhwini bazoshisa kancane noma bashise ngisho nangemva kokushaya izingcingo, ukuphequlula i-inthanethi noma ukudlala imidlalo isikhathi eside, okubangelwa ukwamukelwa nokudluliselwa njalo kwezimpawu ezibangelwa omakhalekhukhwini, futhi abantu abathola i-MRI bafana nje nomakhalekhukhwini. Ngemva kokuba abantu beqhubeka nokuthola izimpawu ze-RF, amandla azokhishwa ekushiseni, ngakho bazozizwa beshisa kancane futhi bakhiphe ukushisa ngokujuluka. Ngakho-ke, ukujuluka ngesikhathi se-MRI kuyinto evamile.
Kungani kunomsindo omkhulu kangaka ngesikhathi se-MRI?
Umshini we-MRI unengxenye yangaphakathi ebizwa ngokuthi “i-gradient coil”, ekhiqiza ugesi oshintsha njalo, futhi ukushintshashintsha okubukhali kogesi kuholela ekudlidlizeni kwe-coil okuvama kakhulu, okukhiqiza umsindo.
Njengamanje, umsindo obangelwa imishini ye-MRI ezibhedlela ngokuvamile ungama-decibel angu-65 ~ 95, futhi lo msindo ungabangela umonakalo othile ekuzweni kweziguli lapho zithola i-MRI ngaphandle kwamadivayisi okuvikela izindlebe. Uma ama-earplug esetshenziswa kahle, umsindo ungancishiswa ube ngama-decibel angu-10 kuya kwangu-30, futhi ngokuvamile akukho monakalo ekuzweni.
Ingabe udinga "ukuhlolwa" kwe-MRI?
Kukhona uhlobo lokuhlolwa ku-MRI olubizwa ngokuthi ama-enhanced scan. I-MRI scan enhanced idinga ukujovwa nge-intravenous umuthi odokotela be-radiation abawubiza ngokuthi “i-contrast agent,” ikakhulukazi i-contrast agent equkethe “i-gadolinium.” Nakuba ukwanda kokusabela okubi ngama-gadolinium contrast agents kuphansi, kusukela ku-1.5% kuya ku-2.5%, akufanele kunganakwa.
Ukusabela okubi kwe-gadolinium contrast agents kwakuhlanganisa isiyezi, ikhanda elibuhlungu lesikhashana, isicanucanu, ukuhlanza, ukuqubuka, ukuphazamiseka kokunambitha, kanye nokubanda endaweni yokujova. Ukwanda kokusabela okubi kakhulu kuphansi kakhulu futhi kungabonakala njengokuphelelwa umoya, ukwehla komfutho wegazi, i-asthma ye-bronchial, i-pulmonary edema, ngisho nokufa.
Iningi leziguli ezinezinkinga ezinkulu zokuphefumula zazinomlando wesifo sokuphefumula noma isifo sokungezwani komzimba. Ezigulini ezinenkinga yezinso, ama-gadolinium contrast agents angandisa ingozi ye-renal systemic fibrosis. Ngakho-ke, ama-gadolinium contrast agents ayavinjelwa kubantu abanenkinga enkulu yokusebenza kwezinso. Uma uzizwa ungaphilile ngesikhathi noma ngemva kokuhlolwa kwe-MRI, yazisa abasebenzi bezokwelapha, uphuze amanzi amaningi, bese uphumula imizuzu engama-30 ngaphambi kokuhamba.
I-LnkMedigxile ekuthuthukisweni, ekukhiqizweni nasekukhiqizweni kwama-injetcor ejenti yokucindezela okuphezulu kanye nezinto ezisetshenziswayo zezokwelapha ezifanele ama-injector amakhulu adumile. Kuze kube manje, i-LnkMed yethule imikhiqizo eyi-10 enamalungelo obunikazi obuzimele ngokuphelele emakethe, okuhlanganisaUmjovo owodwa we-CT, Umjovo wekhanda eliphindwe kabili we-CT, Umjovo we-DSA, Umjovo we-MRI, kanye nesirinji yepayipi yamahora ayi-12 ehambisanayo kanye neminye imikhiqizo yasekhaya esezingeni eliphezulu, iyonkeInkomba yokusebenza isifinyelele ezingeni lomhlaba wonke lesigaba sokuqala, futhi imikhiqizo ithengiswe e-Australia, eThailand, eBrazil nakwamanye amazwe, eZimbabwe nakwamanye amazwe amaningi.I-LnkMed izoqhubeka nokuhlinzeka ngemikhiqizo esezingeni eliphezulu emkhakheni wezithombe zezokwelapha, futhi ilwele ukuthuthukisa ikhwalithi yesithombe kanye nempilo yesiguli. Umbuzo wakho wamukelekile.
