Patinoenda kuchipatara, chiremba achatipa mimwe miedzo yekufungidzira maererano nezvinodiwa nemamiriro ezvinhu, zvakadai seMRI, CT, X-ray film kana Ultrasound. MRI, magnetic resonance imaging, inonzi "nuclear magnetic", ngationei izvo vanhuwo zvavo vanoda kuziva nezveMRI.
Pane radiation muMRI?
Parizvino, MRI ndiyo yega dhipatimendi reradiology isina zvinhu zvekuongororwa kwemwaranzi, vakwegura, vana nevakadzi vane pamuviri vanogona kuita. Kunyange zvazvo X-ray neCT zvichizivikanwa kuva nemwaranzi, MRI haina kuchengeteka.
Sei ndisingakwanisi kutakura zvinhu zvesimbi uye magnetic pamuviri wangu panguva yeMRI?
Muviri mukuru weMRI muchina unogona kufananidzwa nemagineti hombe. Hazvina mhosva kuti muchina wakabatidzwa here kana kuti kwete, iyo hombe yemagineti uye hombe remagineti simba remuchina richagara riripo. Zvinhu zvese zvesimbi zvine iron, zvakaita sezvimedu zvebvudzi, mari, mabhandi, mapini, wachi, nekiresi, mhete nezvimwe zvishongo nezvipfeko, zviri nyore kuyamwa. Magnetic zvinhu, zvakadai semagnetic cards, IC cards, pacemaker, AIDS yekunzwa, nharembozha nezvimwe midziyo yemagetsi, zviri nyore kuita magineti kana kukuvadzwa. Naizvozvo, vamwe vanhu vanoperekedza uye nhengo dzemhuri havafanire kupinda mukamuri yekuvheneka pasina mvumo yevashandi vekurapa; Kana murwere achifanira kuperekedzwa nekuperekedzwa, zvinofanirwa kubvumirana nevashandi vekurapa uye kugadzirirwa zvinoenderana nezvinodiwa nevashandi vekurapa, sekusaunza nharembozha, makiyi, wallet uye zvigadzirwa zvemagetsi muimba yekuvheneka.
Zvinhu zvesimbi uye zvinhu zvemagineti zvakayamwa nemichina yeMRI zvichava nemigumisiro yakakomba: kutanga, chimiro chemufananidzo chichakanganiswa zvakanyanya, uye chechipiri, muviri wemunhu uchakuvadzwa nyore nyore uye muchina uchakuvadzwa panguva yekuongorora. Kana iyo simbi inodyarwa mumuviri wemunhu ikaunzwa musimba remagineti, iyo yakasimba magineti inogona kuita kuti tembiricha yekudyara iwedzere, kupisa uye kukuvadzwa, uye nzvimbo yekuisirwa mumuviri wemurwere inogona kuchinja, uye kunyange kutungamirira kune madhigirii akasiyana. kutsva munzvimbo yemurwere yekuisirwa, iyo inogona kunge yakanyanya seyechitatu-dhigirii kupisa.
MRI inogona kuitwa nemazino emazino here?
Vanhu vazhinji vane mazino emazino vanonetseka nezvekusakwanisa kuwana MRI, kunyanya vanhu vakuru. Chokwadi, kune marudzi akawanda emazino emazino, akadai semazino emazino akaiswa uye anofambika. Kana iyo denture zvinhu isiri simbi kana titanium alloy, haina mhedzisiro paMRI. Kana iyo denture ine iron kana magnetic components, zvakanakisisa kubvisa denture inoshanda kutanga, nokuti zviri nyore kufamba mune magnetic field uye inokanganisa hutano hwekuongorora, iyo ichaitawo kutyisidzira kuchengetedzwa kwevarwere; Kana iri denture yakagadziriswa, usazvidya mwoyo zvakanyanya, nokuti iyo yakagadziriswa denture pachayo haigoni kufamba, izvo zvinoguma zvakagadzirwa zvishoma. Semuyenzaniso, kuita MRI yehuropi, mazino emazino akaiswa anongokanganisa firimu (kureva kuti, mufananidzo) wakatorwa, uye mhedzisiro yacho idiki, kazhinji haikanganisi kuongororwa. Zvisinei, kana chikamu chekuongorora chikaitika chiri munzvimbo ye denture, ichiri nemigumisiro yakakura pafirimu, uye mamiriro ezvinhu aya mashoma, uye vashandi vezvokurapa vanoda kubvunzurudzwa panzvimbo. Usarega kudya uchitya kukachidzwa, nekuti hauite MRI nekuti wakagadzirisa mazino.
Sei ndichinzwa kupisa uye kudikitira panguva yeMRI?
Sezvatinoziva tese, nharembozha dzichange dzichipisa zvishoma kana kutopisa mushure mekufona, kusevha Internet kana kutamba mitambo kwenguva yakareba, izvo zvinokonzerwa nekugashira kugashira uye kutapurirana kwezviratidzo kunokonzerwa nenharembozha, uye vanhu vari kuita MRI. dzakangofanana nenharembozha. Mushure mekunge vanhu varamba vachigamuchira masaini eRF, simba racho rinoburitswa mukupisa, saka vanozonzwa kupisa uye kubvisa kupisa kuburikidza nekudikitira. Nokudaro, kudikitira panguva yeMRI kwakajairika.
Sei kune ruzha rwakanyanya panguva yeMRI?
Muchina weMRI une chikamu chemukati chinonzi "gradient coil", iyo inobudisa nguva inogara ichichinja, uye kuchinja kwakapinza kwezvino kunotungamirira kukudengenyeka kwepamusoro-soro yekoil, iyo inobudisa ruzha.
Parizvino, ruzha runokonzerwa nemichina yeMRI muzvipatara kazhinji kacho 65 ~ 95 decibels, uye ruzha urwu runogona kukonzera kumwe kukuvadza pakunzwa kwevarwere pavanogamuchira MRI pasina midziyo yekudzivirira nzeve. Kana zvinovhara nzeve zvikashandiswa zvakanaka, ruzha runogona kuderedzwa kusvika pamadecibel 10 kusvika ku30, uye hapawanzokuvadzi pakunzwa.
Iwe unoda "pfuti" yeMRI?
Pane kirasi yebvunzo muMRI inonzi enhanced scans. Kuongororwa kweMRI kwakakwidziridzwa kunoda kubaiwa jekiseni remutsinga remushonga unonzi neradiologists "contrast agent," kunyanya mumiririri une "gadolinium." Kunyange zvazvo chiitiko chekusagadzikana kwegadolinium kusiyana kwevamiririri chakaderera, kubva pa1.5% kusvika ku2.5%, haifanirwe kufuratirwa.
Maitiro akashata egadolinium akasiyana maagent aisanganisira dzungu, kutemwa nemusoro, kuda kurutsa, kurutsa, mapundu, kukanganisa kuravira, uye kutonhora panzvimbo yejekiseni. Chiitiko chekukanganisa kwakakomba kwakadzikira zvakanyanya uye chinogona kuratidzwa sedyspnea, kuderera kweBP, bronchial asthma, pulmonary edema, uye kunyange kufa.
Varwere vazhinji vaive nekusagadzikana kwakanyanya vaive nenhoroondo yechirwere chekufema kana allergic chirwere. Muvarwere vane renal insufficiency, gadolinium musiyano maajenti anogona kuwedzera njodzi yerenal systemic fibrosis. Naizvozvo, gadolinium kusiyanisa vamiririri vanopikiswa muvanhu vane zvakanyanya kukanganiswa renal basa. Kana iwe uchinzwa usina kunaka panguva kana shure kwekuongororwa kweMRI, zivisa vashandi vezvokurapa, inwa mvura yakawanda, uye zorora kwemaminitsi makumi matatu usati waenda.
LnkMedinotarisa pakuvandudza, kugadzira uye kugadzirwa kweiyo high pressure difference agent injetcors uye zvinodyiwa zvekurapa zvakafanira majekiseni makuru anozivikanwa. Kusvika pari zvino, LnkMed yakaparura zvigadzirwa gumi zvine kodzero dzakazvimiririra yehungwaru kumusika, kusanganisiraCT jekiseni rimwe chete, CT mbiri mbiri jekiseni, DSA jekiseni, MRI jekiseni, uye inoenderana 12-awa pombi sirinji uye zvimwe zvemhando yepamusoro zvigadzirwa zvepamba, zvakazaraperformance index yasvika padanho repasi rose rekutanga, uye zvigadzirwa zvakatengeswa kuAustralia, Thailand, Brazil, nedzimwe nyika. Zimbabwe nedzimwe nyika dzakawanda.LnkMed icharamba ichipa zvigadzirwa zvemhando yepamusoro kumunda wekufungidzira kwekurapa, uye kuyedza kuvandudza mhando yemufananidzo uye hutano hwemurwere. Kubvunza kwako kunogamuchirwa.
