Xa sisiya esibhedlele, ugqirha uya kusinika ezinye iimvavanyo ze-imaging ngokwemfuno yemeko, njenge-MRI, i-CT, ifilimu ye-X-ray okanye i-Ultrasound. I-MRI, i-imaging resonance magnetic, ebizwa ngokuba yi "nuclear magnetic", makhe sibone ukuba abantu abaqhelekileyo kufuneka bazi ntoni ngeMRI.
Ngaba kukho ukusasazeka kwemitha kwiMRI?
Okwangoku, i-MRI kuphela kwesebe le-radiology ngaphandle kwezinto zovavanyo lwe-radiation, abantu abadala, abantwana kunye nabasetyhini abakhulelweyo abanokuyenza. Ngelixa iX-reyi kunye ne-CT zaziwa ngokuba zinemitha, iMRI ikhuselekile.
Kutheni ndingakwazi ukuthwala izinto zetsimbi kunye nemagnethi emzimbeni wam ngexesha le-MRI?
Umzimba oyintloko womatshini we-MRI unokuthelekiswa nemagnethi enkulu. Kungakhathaliseki ukuba umatshini uvuliwe okanye awuvulwanga, indawo enkulu yamagnetic kunye namandla amakhulu omatshini aya kuhlala ekhona. Zonke izinto zentsimbi eziqulethe intsimbi, njengeekliphu zeenwele, iingqekembe, amabhanti, izikhonkwane, iiwotshi, iintsimbi zomqala, amacici kunye nezinye izacholo kunye nempahla, kulula ukufunxwa. Izinto zemagnethi, ezifana namakhadi emagnethi, amakhadi e-IC, izincedisi-ntliziyo, uGawulayo weendlebe, iiselfowuni nezinye izixhobo zombane, zenziwa imagnethi okanye zonakaliswe ngokulula. Ke ngoko, abanye abantu abahamba kunye namalungu osapho akufuneki bangene kwigumbi lokuskena ngaphandle kwemvume yabasebenzi bezonyango; Ukuba isigulana kufuneka sikhatshwe sisikhatshwa, kufuneka kuvunyelwane ngaso ngabasebenzi bezonyango size silungiswe ngokweemfuno zabasebenzi bezonyango, njengokungazisi iiselfowuni, izitshixo, izipaji nezixhobo zombane kwigumbi lokuskena.
Izinto zetsimbi kunye nezinto zamagnetic ezifunxwa ngoomatshini be-MRI ziya kuba nemiphumo emibi: okokuqala, umgangatho womfanekiso uya kuchaphazeleka kakhulu, kwaye okwesibini, umzimba womntu uya kulimala ngokulula kwaye umatshini uya konakala ngexesha lokuhlolwa. Ukuba ukufakelwa kwesinyithi kumzimba womntu kuziswa kumhlaba wemagnethi, intsimi yemagnethi eyomeleleyo inokwenza ubushushu bokufakelwa bonyuke, ubushushu obugqithisileyo kunye nomonakalo, kwaye indawo yokufakelwa emzimbeni wesigulana inokutshintsha, kwaye ide ikhokelele kwiidigri ezahlukeneyo. ukutsha kwindawo yofakelo lwesigulana, enokuba nzima njengokutsha kwenqanaba lesithathu.
Ngaba iMRI inokwenziwa ngamazinyo emboleko?
Abantu abaninzi abanamazinyo okufakelwa banexhala lokungakwazi ukufumana iMRI, ngakumbi abantu abadala. Enyanisweni, zininzi iindidi zamazinyo emboleko, njengamazinyo emboleko angatshintshiyo kunye namazinyo anokushenxiswa. Ukuba i-denture material ayiyontsimbi okanye i-titanium alloy, inempembelelo encinci kwi-MRI. Ukuba i-denture iqulethe i-iron okanye i-magnetic components, kungcono ukususa i-denture esebenzayo kuqala, kuba kulula ukuhamba kwintsimi yamagnetic kwaye ichaphazele umgangatho wokuhlolwa, okuya kubangela ingozi ekukhuseleni izigulane; Ukuba i-denture esisigxina, ungakhathazeki kakhulu, kuba i-denture esisigxina ngokwayo ayiyi kuhamba, i-artifacts ebangelwayo incinci. Umzekelo, ukwenza i-MRI yobuchopho, amazinyo emboleko esisigxina kuphela anempembelelo ethile kwifilimu (oko kukuthi, umfanekiso) othathiweyo, kwaye impembelelo incinci, ngokuqhelekileyo ayichaphazeli ukuxilongwa. Nangona kunjalo, ukuba inxalenye yoviwo iyenzeka kwindawo ye-denture, isenayo impembelelo enkulu kwifilimu, kwaye le meko incinci, kwaye abasebenzi bezonyango kufuneka badibane nabo kwindawo. Ungayeki ukutya ngenxa yokoyika ukuminxeka, kuba awuyenzi iMRI kuba unamazinyo okufakelwa.
Kutheni ndiziva ndishushu kwaye ndibile ngexesha le-MRI?
Njengoko sonke sisazi, iifowuni eziphathwayo ziya kuba shushu kancinci okanye zishushu kakhulu emva kokufowuna, ukusefa i-Intanethi okanye ukudlala imidlalo ixesha elide, oku kungenxa yokwamkelwa rhoqo kunye nokuhanjiswa kwemiqondiso ebangelwa ziifowuni eziphathwayo, kunye nabantu abafumana iMRI. zifana nje neeselfowuni. Emva kokuba abantu beqhubekile befumana imiqondiso yeRF, amandla aya kukhululwa abe bubushushu, ngoko ke baya kuziva beshushu kancinci kwaye bakhuphe ubushushu ngokubila. Ngoko ke, ukubila ngexesha le-MRI kuyinto eqhelekileyo.
Kutheni kukho ingxolo eninzi ngexesha le-MRI?
Umatshini we-MRI unecandelo langaphakathi elibizwa ngokuthi "i-coil ye-gradient", evelisa i-current eguqukayo ngokuqhubekayo, kunye nokutshintsha okubukhali kwangoku kukhokelela kwi-high-frequency vibration ye-coil, evelisa ingxolo.
Okwangoku, ingxolo ebangelwa zizixhobo zeMRI ezibhedlele ngokuqhelekileyo i-65 ~ 95 decibels, yaye le ngxolo inokubangela umonakalo othile kwindlebe yomguli xa ifumana iMRI ngaphandle kwezixhobo zokukhusela indlebe. Ukuba iindlebe zisetyenziswa kakuhle, ingxolo inokuthotywa ibe zii<em>decibel ezili-10 ukusa kwezingama-30, yaye ngokuqhelekileyo akukho monakalo ekuveni.
Ngaba ufuna "ukudubula" kwi-MRI?
Kukho udidi lweemviwo kwi-MRI olubizwa ngokuba zizikena eziphuculweyo. Ukujongwa kwe-MRI eyongeziweyo kufuna inaliti yeyeza elibizwa ngokuba ziingcali ngemitha “yi-agent echasayo,” eyona nto iphambili iqulethe i-“gadolinium.” Nangona iziganeko zokuchasana ne-gadolinium ziphantsi, ukusuka kwi-1.5% ukuya kwi-2.5%, akufanele zingahoywa.
Iziphumo ezingathandekiyo ze-gadolinium ezichaseneyo zibandakanya isiyezi, intloko ebuhlungu yexeshana, isicaphucaphu, ukugabha, irhashalala, ukuphazamiseka kwencasa, kunye nokubanda kwindawo yokutofa. Izehlo zeziphumo ezibi kakhulu ziphantsi kakhulu kwaye zinokubonakaliswa njenge-dyspnea, ukuncipha koxinzelelo lwegazi, i-asthma ye-bronchial, i-pulmonary edema, kunye nokufa.
Uninzi lwezigulane ezineempembelelo ezimbi kakhulu zinembali yesifo sokuphefumla okanye isifo se-allergies. Kwizigulane ezinokusilela kwezintso, ii-agent zokuchasana ze-gadolinium zinokunyusa umngcipheko we-renal systemic fibrosis. Ke ngoko, ii-agent zokuchasa i-gadolinium azichanekanga kubantu abanokungasebenzi kakuhle kwezintso. Ukuba uziva ungaphilanga ngexesha okanye emva kokuxilongwa kwe-MRI, yazisa abasebenzi bezonyango, sela amanzi amaninzi, kwaye uphumle imizuzu engama-30 ngaphambi kokuba uhambe.
LnkMedijolise kuphuhliso, ukuveliswa kunye nokuveliswa kwee-ejenti ezichasene noxinzelelo oluphezulu kunye nezinto ezisetyenziswayo zonyango ezifanelekileyo kwii-injection ezinkulu ezaziwayo. Ukuza kuthi ga ngoku, i-LnkMed isungule iimveliso ezili-10 ezinamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda kwimarike, kuquka.CT isitofu esisodwa, CT isitofu sentloko ezimbini, Isitofu seDSA, Isitofu seMRI, kunye nesirinji yombhobho ehambelanayo yeeyure ezili-12 kunye nezinye iimveliso zasekhaya ezikumgangatho ophezulu, ngokubanziisalathisi sokusebenza sifikelele kwinqanaba lodidi lokuqala lwamazwe ngamazwe, kwaye iimveliso zithengiswe e-Australia, eThailand, eBrazil, nakwamanye amazwe. iZimbabwe kunye namanye amazwe amaninzi.I-LnkMed iya kuqhubeka nokubonelela ngeemveliso ezikumgangatho ophezulu kwintsimi yokucinga ngonyango, kwaye izame ukuphucula umgangatho womfanekiso kunye nempilo yesigulane. Umbuzo wakho wamkelekile.
