CT neMRI zvinoshandisa nzira dzakasiyana kuratidza zvinhu zvakasiyana - hapana chimwe chazvo chiri "nani" kupfuura chimwe.
Mamwe maronda kana mamiriro ezvinhu anogona kuonekwa nemaziso asina kujeka. Mamwe anoda kunzwisisa kwakadzama.
Kana chiremba wako achifungidzira kuti une dambudziko rakadai sekubuda ropa mukati memuviri, bundu, kana kukuvara kwetsandanyama, anogona kuraira kuti uitwe CT scan kana MRI.
Sarudzo yekuti woshandisa CT scan here kana kuti MRI iri kumunhu anokupa rubatsiro rwehutano, zvichibva pane zvavanofungidzira kuti vachawana.
CT neMRI zvinoshanda sei? Ndeipi yakanakira chii? Ngatinyatsoongororai.
Kuongororwa kweCT, kupfupikiswa kwe computed tomography scan, kunoshanda semuchina we3D X-ray. Kuongororwa kweCT kunoshandisa X-ray inopfuura nemumurwere ichienda kune detector uku ichitenderera murwere. Inotora mifananidzo yakawanda, iyo inounganidzwa nekombuta kuti igadzire mufananidzo we3D wemurwere. Mifananidzo iyi inogona kushandiswa nenzira dzakasiyana-siyana kuti ione muviri wemunhu.
X-ray yechinyakare inogona kupa chiremba wako mukana wekuona nzvimbo yaive nemifananidzo. Mufananidzo wacho hauchinji.
Asi unogona kutarisa mifananidzo yeCT kuti uone nzvimbo yakaratidzwa. Kana kutenderera uchitarisa kubva kumberi kuenda kumashure kana kudivi kuenda kudivi. Unogona kutarisa chikamu chekunze chenzvimbo yacho. Kana kudhonza mukati mechikamu chemuviri chakaratidzwa.
CT Scan: Inotaridzika sei?
Kuongororwa kweCT kunofanira kuva nzira inokurumidza uye isingarwadzi. Unorara patafura inofamba zvishoma nezvishoma nepa ring scanner. Zvichienderana nezvinodiwa nevanopa hutano, ungangodawo madhayi ekudzivirira ganda kubva muropa. Kuongororwa kwega kwega kunotora nguva isingasviki miniti.
CT scan: Chii chinoitirwa?
Nekuti maCT scanner anoshandisa maX-ray, anogona kuratidza zvinhu zvakafanana nemaX-ray, asi nemazvo. X-ray ipfungwa yakatsetseka yenzvimbo yekutora mifananidzo, nepo CT ichigona kupa mufananidzo wakakwana uye wakadzama.
Kuongororwa kweCT kunoshandiswa kutarisa zvinhu zvakaita se: Mapfupa, Matombo, Ropa, Nhengo, Mapapu, Matanho eKenza, Njodzi dzemudumbu.
Kuongororwa kweCT kunogona kushandiswawo kutarisa zvinhu zvisingaonekwe zvakanaka neMRI, zvakaita semapapu, ropa, uye ura.
CT scan: Njodzi Dzinogona Kuitika
Chinhu chinonyanya kushungurudza vamwe vanhu nezveCT scans (uye X-rays) mukana wekuti vaonekwe nemwaranzi.
Dzimwe nyanzvi dzakataura kuti kupiswa kwemwaranzi inoburitswa neCT scans kunogona kuwedzera njodzi yekenza mune vamwe vanhu. Asi njodzi chaidzo dzinopokana. Food and Drug Administration inoti zvichibva paruzivo rwesainzi rwemazuva ano, njodzi yekenza inobva kuCT mwaranzi "haizivikanwi nenhamba."
Zvisinei, nekuda kwenjodzi dzinogona kuitika dzemwaranzi yeCT, vakadzi vane pamuviri havawanzo kukodzera kuongororwa kweCT kunze kwekunge zvichidikanwa.
Dzimwe nguva, vanachiremba vanogona kusarudza kushandisa MRI pachinzvimbo cheCT kuderedza njodzi yekusangana nemwaranzi. Izvi zvinonyanya kuitika kune vanhu vane matambudziko ehutano anoda kutorwa mifananidzo kakawanda kwenguva yakareba.
MRI
MRI inomiririra magnetic resonance Imaging. Muchidimbu, MRI inoshandisa magineti nemafungu eredhiyo kugadzira mifananidzo mumuviri wako.
Mashandiro ayo chaiwo anosanganisira chidzidzo chefizikisi chakareba. Asi muchidimbu, zvakaita seizvi: Miviri yedu ine mvura yakawanda, inonzi H20. H iri muH20 inomiririra hydrogen. Hydrogen ine maproton — positive charged particles. Kazhinji, maproton aya anotenderera nenzira dzakasiyana. Asi paanosangana nemagnet, semuchina weMRI, maproton aya anokweverwa akananga kumagnet otanga kumira mumutsara.
MRI: Zvakaita sei?
MRI muchina unoshandiswa nechubhu. Kuongororwa kweMRI kunotora maminetsi angangoita makumi matatu kusvika makumi mashanu, uye unofanira kuramba wakanyarara panguva yekuongororwa. Muchina wacho unogona kuita ruzha, uye vamwe vanhu vanogona kubatsirwa nekupfeka maearplugs kana kushandisa mahedhifoni kuti vateerere mimhanzi panguva yekuongororwa. Zvichienderana nezvinodiwa nemupi wako wehutano, vanogona kushandisa intravenous contrast dyes.
MRI: Chii chakaitwa?
MRI inonyatsogona kusiyanisa nyama. Semuenzaniso, vanachiremba vanogona kushandisa CT yemuviri wese kutsvaga bundu. Zvadaro, MRI inoitwa kuti inzwisise zviri nani chero bundu rinowanikwa paCT.
Chiremba wako anogona zvakare kushandisa MRI kuti aone kana majoini akakuvara uye tsinga dzakakuvara.
Dzimwe tsinga dzinogona kuonekwa neMRI, uye unogona kuona kana paine kukuvara kana kuzvimba kwetsinga mune dzimwe nzvimbo dzemuviri. Hatigoni kuona tsinga zvakananga paCT P scan. PaCT, tinogona kuona pfupa rakatenderedza tsinga kana tishu rakatenderedza tsinga kuti tione kana zvine zvazvinoita panzvimbo yatinotarisira kuti tsinga ive. Asi pakutarisa tsinga zvakananga, MRI bvunzo iri nani.
MRIs hadzina kunaka pakutarisa zvimwe zvinhu, zvakaita semapfupa, ropa, mapapu nematumbu. Rangarira kuti MRI inoshandisa magineti kuti ishandise hydrogen mumuviri. Nekuda kweizvozvo, zvinhu zvakaita sematombo eitsvo nemapfupa hazvionekwe. Uye chero chinhu chakazara nemhepo, semapapu ako hachizoonekwe.
MRI: Njodzi Ingangoitika
Kunyange zvazvo MRI ingave nzira iri nani yekutarisa mamwe maumbirwo mumuviri, haisi yemunhu wese.
Kana uine mamwe marudzi esimbi mumuviri wako, MRI haigone kuitwa. Izvi zvinodaro nekuti MRI imagneti chaiyo, saka inogona kukanganisa mamwe maimplant esimbi. Izvi zvinosanganisira mamwe ma pacemaker, ma defibrillator kana shunt devices.
Simbi dzakadai sedzinotsiva majoini dzinowanzo shandiswa pakurapa MRI. Asi usati waongororwa neMRI, iva nechokwadi chekuti chiremba wako anoziva nezvesimbi dziri mumuviri wako.
Pamusoro pezvo, bvunzo yeMRI inoda kuti ugare wakanyarara kwenguva yakati rebei, izvo vamwe vanhu vasingakwanise kutsungirira. Kune vamwe, kuvharika kwemuchina weMRI kunogona kukonzera kuzvidya mwoyo kana claustrophobia, izvo zvinoita kuti kutora mifananidzo kuve kwakaoma zvikuru.
Imwe iri nani pane imwe here?
Kuongororwa kweCT neMRI hazvisi nyore nguva dzose, inyaya yekuti uri kutsvaga chii uye kuti unotsungirira sei zvese zviri zviviri. Kazhinji, vanhu vanofunga kuti chimwe chiri nani pane chimwe. Asi zvinoenderana nekuti chiremba wako ari kubvunza chii.
Chinhu chikuru: Kunyangwe chiremba wako akaraira CT kana MRI, chinangwa ndechekunzwisisa zviri kuitika mumuviri wako kuti akupe kurapwa kwakanakisa.
