Kuongorora Kubatsirwa Kwavo, Zviratidzo, uye Kukanganisa
Uropi uye nervous system inogona kuonekwa nekombiyuta inoongorora (CT) scans uye magnetic resonance imaging (MRI) . Paanotarisana nechirwere chepfungwa, nyanzvi yezvehutano ine ruzivo inowanzowedzera kuongororwa pasina kudikanwa kwekuwedzerwa kuongororwa. Pane dzimwe nguva, zvinogona kubatsira (kana kunyange zvakakurumidzirwa) kuronga bheteri yeongororo yekutsvaga mhepo kuti uwane kana kuongorora zvinetso zvisingazivikanwi nyore nyore.

Kuenzanisa CT Scans naM MRIs
Izwi rokuti neuroimaging rinotsanangura nzira dzekucherechedza uropi uye zvimwe zvikamu zvehurongwa hwemitsipa kuti dzigadzirise kana kubvisa kunze kwekunyunyuta kweeurologist. MRIs neC CT zvikwangwani zvinhu zviviri zvakadaro izvo nyanzvi yezveuropi inogara ichienda kune iyo.
Kutaura mitauro, MRI yakafanana nekodhura, yekodhi-kamera kamera apo CT scan yakafanana nemutengo usina kukwana kamera. Kuenzanisa kwakatonyanya kukoshesa nokuti mari yeMRI inopfuura kudarika yeC CT scan.
Izvi hazvirevi hazvo kuti munhu anowanikwa zvakanakisisa kupfuura mumwe. Vamwe vanhu vanofungidzira kuti, nokuti hutano hwekufungidzira hweMRI hwakareba, hunofanira kugara huri sarudzo yekutanga. Asi izvo zvinoratidza kusanzwisisana kwakawanda pamusoro pehutaneti, zvose maererano nemasimba avo uye kukanganisa.
Kunyanya kutaura, MRI uye CT scan zvakasiyana nenzira nhatu dzakasiyana:
- Kana nguva iri yezvakakosha. MRI inogona kutora maminitsi 45 ekupedzisa asi CT inogona kungotora maminitsi mashanu kusvika gumi. Mune nguva inotora kuwana MRI yakaitwa (nokuti, ichiti, chirwere chakakomba chisingaiti muviri ) munhu angave akafa kana kukuvadzwa zvakakomba. MRI inodawo kuti munhu ave akadaro kwenguva yakareba, iyo inogona kuva yakaoma mune imwe nguva. A CT scan ndiyo inowanzoita sarudzo yakanakisisa yezviitiko zvakadai.
- Mhando dzisina kunaka dzavanoona. Mune mamwe mamiriro ezvinhu, CT scan inogona kuona kusagadzikana nyore nyore kupfuura MRI, kusanganisira kubuda ropa uye kuputika kwemapfupa. Kusiyana neizvi, mRI inobatsira pakucherechedza zvipembenene zviduku kana zvisinganyengeri zvakadai sa multiple sclerosis plaques, acoustic neuromas , kana astrocytomas iri pasi .
- Kushamwaridzana nemifananidzo yekufananidzira. MRIs inoshandisa mifananidzo uchishandisa masimba maginetic. Zvimwe zvipfeko zvesimbi uye zvisizvo zvisingawiriki zvinogona kukanganisa mazaya aya, zvichikonzera kusvibisa kwemifananidzo. Muchidimbu chimwechete, misi yemirairo inoshandiswa neT CT scan inogona kuparadzirwa ne dense bone (ichiti, yakakomberedza uropi hunopera), zvinotungamirira kumufananidzo wakaoma kana kunyange asingakwanisi kududzira.
Ngozi
Nzvimbo huru dzinotyisa dambudziko mumitambo iyi inobva mumifananidzo yekufungidzira uye kubva kune avo vanosiyanisa. Hezvino maitiro aya matambudziko akasiyana nemhando mbiri dzekufungidzira.
Imaging
CT inoongorora inoshandisa X-rays kuti igadzire mufananidzo unotenderera. Sezvo zvakadaro, huwandu hwemazuva akabatanidzwa hunogona kunge huri pamusoro, pamwe nedzimwe tsvakurudzo dzinoratidzira 1 muzana mukana wekuwana kenza semuenzaniso wekutarisa. Izvi zvinowanzova nehanya nevechidiki kubva pakuberekwa kwekenza kazhinji zvinotora makumi emakore kuratidza. Nokuda kwechikonzero ichi, vanachiremba vanowanzova vakangwarira pakuita CT scan pane mwana kupfuura munhu mukuru akwegura.
MRI, nenzira yakasiyana, inoshandisa magnetti ane simba zvikuru ekusimudzira maatomu mumuviri womunhu. Maatomu iwayo anobva aonekwa ne scanner. Dambudziko guru reMRI nderokuti chero ipi zvayo inogadzirwa nemagetsi inogona kuva magnetic pasi pesimba reMRI uye edza kugadzirisa puro-pole Izvi zvinogona kuita kuti kuiswa kwekudzingwa kuve kwakasununguka kana kupisa.
Kusiyanisa Vashandi
Mune zvimwe zviitiko, mapurogiri eurologists achashandisa dhayi yakasiyana kuti ayanise zviri nani zviri kuitika mukati meuropi. Kusiyana kwemavara kunogona kubatsira pakuratidza kusapinda kwevasculaya zvakadai seanerysysm yeuropi kana zvipembenene zvinosangana neAicute yakaoma, chirwere chinopisa, kana kenza.
Mune zvose zviri zviviri CT inoongorora uye MRIs, mutengesi wacho anokwanisa kukonzera zvinetso zvakakomba:
- CT inoshandisa shanduko yakasiyana iyo inogona kunge iodini. Mune dzimwe nguva zvisingawanzoitiki, kubudisa iodini kunogona kukonzera zvakakomba kuhupenyu-kutyisa kugadziriswa kwemagetsi.
- MRI scanners vanoshandisa muparanisi anonzi gadolinium. Mune vanhu vane chirwere chetsvo, kuwedzerwa kwegadolinium kunogona kukonzera chirwere chisingawanzo asi chakaipa chinonzi nephrogenic systemic fibrosis (NSF).
Shoko Rinobva
Pane zvakawanda zvinoda kuongororwa zvisati zvaitika kuongororwa neuroimaging. Sezvo murwere, nguva dzose inokosha kuzivisa chiremba wako pamusoro pehupi hwehutachiona, kuisa, uye hutano (kusanganisira kurapwa kwekenza) iwe unogona kunge wakanga uine. Iwe unofanirwawo kuendesa chero chinhu chipi zvacho chaunonetseka pamusoro pechirongwa wacho pachako, kunyanya kana iwe une claustrophobia kana kuti wakambova nematambudziko akaipa munguva yakapfuura. Zvimwe zvinogona kuwanikwa. Kana shanduro yekufungidzira inosarudzwa nokuchenjera uye nehuwandu huripo hwemu murwere, inogona kubatsira zvikuru kuti unyatsogadzikana uye kururamisa kwekuongororwa. Taura nechiremba wako kana kuwana imwe pfungwa, kana zvichidikanwa.
