Patinoenda kuchipatara, chiremba anotipa mimwe miedzo yekufungidzira zvinoenderana nezvinodiwa nemamiriro ezvinhu, zvakaita seMRI, CT, X-ray film kana Ultrasound. MRI, magnetic resonance imaging, inonzi "nuclear magnetic", ngationei zvinodiwa nevanhuwo zvavo nezveMRI.
Pane radiation here muMRI?
Parizvino, MRI ndiyo yega dhipatimendi reX-ray risina zvinhu zvekuongororwa nemwaranzi, vakwegura, vana nevakadzi vane pamuviri vanogona kuzviita. Kunyange zvazvo X-ray neCT zvichizivikanwa kuti zvine mwaranzi, MRI haina njodzi.
Sei ndisingakwanise kutakura zvinhu zvesimbi nemagnetic mumuviri wangu panguva yeMRI?
Muviri mukuru wemuchina weMRI unogona kuenzaniswa nemagneti hombe. Hazvina mhosva kuti muchina wacho wakabatidzwa here kana kuti kwete, simba guru remagnetic nesimba guru remagnetic remuchina zvichagara zviripo. Zvinhu zvese zvesimbi zvine simbi, zvakaita sehair clips, mari, mabhandi, mapini, mawachi, mitsipa yemutsipa, mhete nezvimwe zvishongo nezvipfeko, zviri nyore kumedzwa. Zvinhu zvemagnetic, zvakaita semakadhi emagineti, makadhi eIC, pacemakers, hearing AIDS, nharembozha nezvimwe zvishandiso zvemagetsi, zvinokurumidzirwa kana kukuvara zviri nyore. Naizvozvo, vamwe vanhu vanoperekedza nevemhuri havafanirwe kupinda mukamuri rekuskena vasina mvumo yevashandi vekurapa; Kana murwere achifanira kuperekedzwa nemuperekedzi, zvinofanirwa kubvumirana nevashandi vekurapa uye kugadzirirwa zvinoenderana nezvinodiwa nevashandi vekurapa, zvakaita sekusaunza nharembozha, makiyi, mawallets nezvishandiso zvemagetsi mukamuri rekuskena.
Zvinhu zvesimbi nezvinhu zvine magineti zvinosvetwa nemichina yeMRI zvichava nemigumisiro yakakomba: chekutanga, kunaka kwemufananidzo kuchakanganiswa zvakanyanya, uye chechipiri, muviri wemunhu uchakuvara zviri nyore uye muchina uchakuvara panguva yekuongorora. Kana simbi yakaisirwa mumuviri wemunhu ikaunzwa mumunda wemagineti, simba remagineti rakasimba rinogona kuita kuti tembiricha yekuisa muchina iwedzere, kupisa zvakanyanya uye kukuvara, uye nzvimbo yekuisa muchina mumuviri wemurwere inogona kuchinja, uye kutotungamira kune mwero wakasiyana wekutsva panzvimbo yekuisa muchina wemurwere, izvo zvinogona kuva zvakanyanya sekutsva kwedhigirii rechitatu.
MRI inogona kuitwa here nemazino ekugadzira?
Vanhu vazhinji vane mazino ekugadzira vanonetseka nezvekusakwanisa kuongororwa MRI, kunyanya vanhu vakuru. Kutaura zvazviri, kune marudzi akawanda emazino ekugadzira, akadai semazino ekugadzira akagadzika uye mazino ekugadzira anofambiswa. Kana mazino ekugadzira asiri esimbi kana titanium alloy, haanyanyi kukanganisa MRI. Kana mazino ekugadzira aine iron kana magnetic components, zvakanaka kutanga wabvisa mazino ekugadzira ari kushanda, nekuti zviri nyore kufamba mumunda wemagineti uye zvinokanganisa kunaka kwekuongorora, izvo zvichakonzerawo njodzi kuchengetedzeka kwevarwere; Kana ari mazino ekugadzira akagadzika, usanyanya kunetseka, nekuti mazino ekugadzira akagadzika haafambi, zvinhu zvinobva zvabuda zvidiki. Semuenzaniso, kuita brain MRI, mazino ekugadzira akagadzika ane simba rakati pafirimu (ndiko kuti, mufananidzo) wakatorwa, uye simba racho riri diki, kazhinji harikanganisi kuongororwa. Zvisinei, kana chikamu chekuongorora chikaitika chiri panzvimbo yemazino ekugadzira, chichiri ne simba guru pafirimu, uye mamiriro aya mashoma, uye vashandi vekurapa vanofanira kubvunzwa panzvimbo yacho. Usarega kudya uchitya kudzipwa, nekuti hauite MRI nekuti une mazino ekugadzira akagadziriswa.
Sei ndichinzwa kupisa uye kudikitira panguva yeMRI?
Sezvatinoziva tese, nharembozha dzinopisa zvishoma kana kutopisa mushure mekufona, kutsvaga ruzivo paindaneti kana kutamba mitambo kwenguva yakareba, izvo zvinokonzerwa nekugamuchira uye kutumira zviratidzo nguva nenguva zvinokonzerwa nenharembozha, uye vanhu vari kuita MRI vakafanana nenharembozha. Mushure mekunge vanhu varamba vachigamuchira zviratidzo zveRF, simba racho rinoburitswa mukupisa, saka vanonzwa kupisa zvishoma vobvisa kupisa kuburikidza nekudikitira. Saka, kudikitira panguva yeMRI zvakajairika.
Sei paine ruzha rwakawanda panguva yeMRI?
Muchina weMRI une chikamu chemukati chinonzi "gradient coil", chinoburitsa magetsi anogara achichinja, uye kuchinja kwakasimba kwemagetsi kunotungamira mukutenderera kwemagetsi emagetsi, izvo zvinoburitsa ruzha.
Parizvino, ruzha runokonzerwa nemidziyo yeMRI muzvipatara runowanzova madecibels 65 ~ 95, uye ruzha urwu runogona kukonzera kukuvara kwekunzwa kwevarwere pavanogamuchira MRI vasina michina yekudzivirira nzeve. Kana maearplugs akashandiswa nemazvo, ruzha runogona kuderedzwa kusvika pamadecibels gumi kusvika makumi matatu, uye kazhinji hapana kukuvara kwekunzwa.
Unoda "jekiseni" reMRI here?
Kune mhando yeongororo muMRI inonzi enhanced scans. Kuongororwa kweMRI kunoda kubaiwa mushonga unotumidzwa nevanoongorora radiation kuti "contrast agent," kunyanya contrast agent ine "gadolinium." Kunyangwe kuwanda kwekusawirirana negadolinium contrast agents kuri pasi, kubva pa1.5% kusvika 2.5%, hazvifanirwe kufuratirwa.
Kukanganisa kwegadolinium contrast agents kwaisanganisira dzungu, musoro unongoerekana wapera, kuda kurutsa, kurutsa, mapundu, kuravira kusina kunaka, uye dzihwa panzvimbo yekubaiwa jekiseni. Kuwanda kwekusawirirana kwakanyanya kwakaderera zvikuru uye kunogona kuratidzwa sekushaya simba, kudzikira kweropa, asthma yebronchial, kuzvimba kwemapapu, uye kunyange kufa.
Varwere vazhinji vane zviratidzo zvakakomba zvekutadza kushanda zvakanaka vaiva nenhoroondo yezvirwere zvekufema kana chirwere cheallergy. Kune varwere vane dambudziko reitsvo, mishonga ye gadolinium inogona kuwedzera njodzi ye renal systemic fibrosis. Nokudaro, mishonga ye gadolinium contrast haibvumidzwe kushandiswa kune vanhu vane dambudziko guru reitsvo. Kana uchinzwa kusagadzikana panguva yekuongororwa kweMRI kana mushure mayo, zivisa vashandi vekurapa, inwa mvura yakawanda, uye zorora kwemaminitsi makumi matatu usati waenda.
