Kana munhu akakuvara paanenge achirovedza muviri, chiremba wake acharaira kuti apihwe X-ray. MRI ingangodiwa kana yakanyanya kuipa. Zvisinei, vamwe varwere vanonetseka zvekuti vanoda munhu anogona kutsanangura zvakadzama kuti rudzi urwu rwebvunzo runosanganisirei uye zvavangatarisira.
Zvinonzwisisika kuti chero dambudziko rehutano rinogona kukonzera kunzwa kwekuzvidya mwoyo uye kusagadzikana. Zvichienderana nemamiriro ezvinhu, timu yekutarisira murwere inogona kutanga nekuongororwa kwemifananidzo senge X-ray, bvunzo isingarwadzi iyo inounganidza mifananidzo yezvimiro mumuviri. Kana paine rumwe ruzivo rwakawanda - kunyanya nezvenhengo dzemukati kana nyama dzakapfava - MRI inogona kudiwa.
MRI, kana kuti magnetic resonance imaging, inzira yekurapa inoshandisa masimba emagineti nemafungu eredhiyo kugadzira mifananidzo yakadzama yenhengo nematishu mumuviri.
Vanhu vanowanzova nekusanzwisisana kwakawanda uye mibvunzo pavanenge vachiongororwa MRI. Heino mibvunzo mishanu inonyanya kubvunzwa nevanhu mazuva ese. Ndinovimba izvi zvichakubatsira kunzwisisa zvaunotarisira kana waongororwa neX-ray.
1. Izvi zvinotora nguva yakareba sei?
Pane zvikonzero zvakawanda zvinoita kuti bvunzo dzeMRI dzitore nguva yakareba kupfuura maX-ray nemaCT scans. Chekutanga, electromagnetism inoshandiswa kugadzira mifananidzo iyi. Tinogona kukurumidza kana miviri yedu yakashongedzwa nemagineti. Chechipiri, chinangwa ndechekugadzira mifananidzo yakanakisisa, zvinoreva kuti nguva yakawanda iri mukati me scanner. Asi kujekesa zvinoreva kuti vanachiremba ve radiology vanowanzo kwanisa kuona pathology zvakajeka mumifananidzo yedu kupfuura mumifananidzo inobva kune dzimwe nzvimbo.
2. Sei varwere vachifanira kuchinja mbatya dzangu nekubvisa zvishongo zvangu?
Michina yeMRI ine magineti anogadzira kupisa uye anogadzira simba remagineti rakasimba kwazvo, saka zvakakosha kuti uve wakachengeteka. Magineti anogona kudhonza zvinhu zvine ferrous, kana zvine iron, mumuchina nesimba guru. Izvi zvinogonawo kukonzera kuti muchina utenderere nekumonereka netambo dzemagineti dzinoyerera. Zvinhu zvisina ferrous zvakaita sealuminium kana copper zvinogadzira kupisa kana zvapinda mu scanner, izvo zvinogona kukonzera kutsva. Pane dzimwe nguva apo mbatya dzakapiswa. Kuti tidzivise chero dambudziko iri, tinokumbira varwere vese kuti vapfeke mbatya dzakatenderwa kuchipatara uye vabvise zvishongo zvese nemidziyo yakaita semafoni, zvinhu zvinobatsira kunzwa nezvimwe zvinhu mumuviri.
3. Chiremba wangu anoti chisimbiso changu chakachengeteka. Sei ruzivo rwangu ruchidiwa?
Kuti murwere wese nenyanzvi vagare vakachengeteka, zvakakosha kuziva kana mimwe michina, yakaita se pacemakers, stimulators, clips, kana coils, yakaiswa mumuviri. Midziyo iyi inowanzouya nemajenareta kana mabhatiri, saka imwe layer yekuchengetedzwa inodiwa kuti ive nechokwadi chekuti hapana kukanganiswa nemuchina, kugona kwawo kuwana mifananidzo chaiyo, kana kugona kwawo kukuchengetedza. Kana tichiziva kuti murwere ane mudziyo wakaiswa, tinofanira kugadzirisa mashandiro anoita scanner zvichienderana nemirairo yemugadziri. Kunyanya, tinofanira kuva nechokwadi chekuti varwere vanogona kuiswa zvakachengeteka mukati me 1.5 Tesla (1.5T) scanner kana 3 Tesla (3T) scanner. Tesla iyuniti yekuyera simba remagnetic field. Mayo Clinic's MRI scanners anowanikwa mu 1.5T, 3T, uye 7 Tesla (7T) strengths. Vanachiremba vanofanirawo kuva nechokwadi chekuti mudziyo uri mu "MRI safe" mode vasati vatanga scan. Kana murwere akapinda munzvimbo yeMRI asina kutora matanho ese ekuchengetedza, michina inogona kukuvara kana kutsva kunogona kuitika kana murwere anogona kuvhunduka.
4. Murwere achapiwa majekiseni api, kana aripo?
Varwere vazhinji vanobayiwa jekiseni remhando ye contrast media, iro rinoshandiswa kuvandudza mifananidzo. (Contrast media inowanzopinzwa mumuviri wemurwere uchishandisainjector yekudhinda ine simba repamusoroMhando dze contrast media injectors dzinoshandiswa zvakanyanya dzinosanganisirajekiseni reCT rimwe chete, jekiseni reCT remusoro miviri, Jekiseni reMRIuyeInjector yeAngiography ine pressure yakakwira) Majekiseni anowanzoitwa netsinga uye haakuvadzi kana kutsva. Pamusoro pezvo, zvichienderana nekuongororwa kwakaitwa, vamwe varwere vanogona kubayiwa jekiseni remushonga unonzi glucagon, uyo unobatsira kunonoka kufamba kwedumbu kuitira kuti mifananidzo yakanyatsojeka ikwanise kutorwa.
5. Ndinotya claustrophobia. Ko kana ndikanzwa ndisina kuchengetedzeka kana kusagadzikana panguva yebvunzo?
Pane kamera mukati meMRI tube kuitira kuti nyanzvi ikwanise kutarisa murwere. Pamusoro pezvo, varwere vanopfeka mahedhifoni kuitira kuti vagone kunzwa mirairo uye kutaurirana nenyanzvi. Kana varwere vachinzwa kusagadzikana kana kunetseka chero nguva panguva yekuongororwa, vanogona kutaura uye vashandi vanoedza kuvabatsira. Pamusoro pezvo, kune vamwe varwere, mushonga wekunyaradza unogona kushandiswa. Kana murwere asingakwanise kuedzwa MRI, chiremba weX-ray nachiremba anomutumira murwere vachabvunzana kuti vaone kana imwe bvunzo yakakodzera.
6. Zvine basa here kana kuti ndeipi nzvimbo inoshanyirwa kuti iongororwe MRI scan?
Kune mhando dzakasiyana dzema scanner, dzinogona kusiyana zvichienderana nesimba remagineti rinoshandiswa kuunganidza mifananidzo. Kazhinji tinoshandisa ma scanner e1.5T, 3T uye 7T. Zvichienderana nezvinodiwa nemurwere uye chikamu chemuviri chiri kuskeniwa (kureva, uropi, musana, dumbu, ibvi), scanner chaiyo inogona kunge yakakodzera kuona maumbirwo emurwere nemazvo uye kuona chirwere chake.
