Magnetic Resonance kufungidzira (MRI) ndeimwe yemhando yakakosha yekurapa ekurapa nhasi. Inoshandisa minda yakasimba yemagineti uye radiofrequency pulses kune isiri-isingawanikwe mari yekuyambuka-chikamu chevanhu matishu, kutamba basa rakakosha mukutsvaga hosha dzakawanda. Nekudaro, tsika dzechinyakare dzino scanners ine yakavharirwa tubular chimiro, kumanikidza varwere kunyepa vachiri mumutengesi weturu panguva scans. Izvi zvinoumba kushushikana kukuru, kunyanya kune vana, vakuru, uye varwere vane craustrophobia, sekureva nhema mukati megweki rakavharirwa rinogona kuve risingagadzikane. Uyezve, ruzha ruzha runogadzirwa nguva dzose panguva yeMRI scans, kuwedzera kuwedzera kushomeka kwemurwere. Vhura MRI SCENDAY yakave yakagadziriswa zvakanyanya kugadzirisa zvakanyanya murwere ruzivo.
Chinyorwa chikuru chekuvhurika mri ishe yayo c-yakavezwa kana o-yakaumbwa magineti inogadzira iyo yakavhurika yekuwana pamativi ese ezvipenga. Varwere vakamanikidzwa mukuvhura kuti vaone nzvimbo dzekunze panzvimbo pekuvharirwa munzvimbo yakatetepa. Izvi zvinorega zvikuru kunetseka uye kunzwa kwekusungwa. Uye zvakare, kuvhura kuwana MRI inogadzira chete makadhi ekutenderera chete kwezana, kuderedzwa 40

Panyaya yezvikamu zveSystem, Vhura MRICEKEST zvikamu zveMRI Scanner, kusanganisira iyo Magineti Magineri Inogadzira Stectem Magineti Scichilly Scichill, uye Maroji eGradi Simba romumunda remagineti hombe mune yakavhurika MRI inogona kuramba ichisvika 0.2 kusvika ku3 tesla, pane chikamu chemagariro mri. Vhura MRI inosanganisira zvakare zvimwe zvekutengesa zvekutsigira uye maitiro ekugadzirisa kuti ugare iyo yakavhurika yekugadziriswa uye yemurwere kugadziriswa zvinodiwa. Zvakazara, apo nekuvandudza ruzivo rwemurwere, vhura MRI inochengetedza pfungwa dzakakosha dzemagineti rekufungidzira uye richiri kugona kupa mifananidzo yemhando yepamusoro yetishu dzevanhu.
Kuenzaniswa netsika yakavharirwa mri, yakavhurika Mri ine inotevera yakanakira mikana:
1. Zvakanyanya kuderedza craustrophobic kutya. Dhizaini yakavhurika inosimbisa varwere havanzwe mukati memukati medumbu, vachipa nzvimbo yekudzikisira zvakanyanya kune vana, vakweguru, kana crautrophobic varwere. Izvi zvinovandudza kutevedzera uye zvinobvumira kuwanikwa kwemhando yepamusoro scans.
2. Yakanyanya kuderedzwa ruzha, ichibvumira kuti zviongorore zviyero zvakanaka. Vhura mri ruzha mazinga ane makumi mana muzana akaderera pane zvakavharirwa masisitimu. Ruzha rwakaderedzwa runoderedza kushushikana kwemurwere, kubvumira nguva refu inotaridzika uye yakadzama kufungidzira kutora.
3. Zvimwe zvinochinja uye zvinowanikwa kune vese varwere. Ruzha rwakavhurika uye rwakaderedzwa ruzha runoita kuti zviongorore nyore kune vashandisi vengarava, varwere vanokunda, kana avo vane manyawi ekufambisa. Vhura MRI SCANNERS inogona kuongorora varwere zvakananga pasina muviri uye zvepfungwa zvinoshungurudza.
4. Inogonesa kupindira kunyorera. Dhizaini yakavhurika rinopa mukana uri nyore kune varwere panguva yekufunga, kufambisa mri-yakatungamirwa kupindira maitiro. Vanachiremba vanogona kushanda pane varwere chaiyo-nguva vachiramba vachifungidzira nzvimbo yekurapa.
Pane mamwe miganhu yekuvhurika MRI uchienzaniswa neakasarudzika masisitimu:
1. Mhando yemufananidzo inogona kunge yakaderera zvishoma, kunyanya mune yakapfava tissue kusiyanisa uye kugadzirisa. Kugadzirwa kwakavhurika kunoreva kuti munda wemagineti inonyanya kuwanda pane echinyakare cylinders, inotungamira kune yakashongedzwa gradient mutsara uye yakaderera chifananidzo chekugadzirisa. Izvi zvinonyanya kuve mukurumbira pane vasina simba-shamba kuvhura MRI Scanners. Simba 1.5T kana 3T Yakavhurika Scanners inogona kudzorera munda inhomogeneity ine yepamusoro shimming uye pulse kutevedzana dhizaini. Asi zvinonzwika, makona akavharika anogara achiita kuti akwanise kugadzirira uye kushungurudzika minda.
2. Varwere vane ukuru vane vhoriyamu yakakura, uye dhizaini yakavhurika kurwira homogenous magineti munda kufukidzwa pamusoro pavo. Tsika yakavharirwa m ikri scanners zvinongoda kururamisa homogeneity pamusoro peiyo diki cylindrical tunnel nzvimbo, ichizadzisa mhedzisiro iri nani kune varwere vehama. Asi vhura mri vatengesi vari kushanda pamhinduro dzakagadzirirwa senge dzakavhurika nemhirizhonga emurwere uye masimba masimba masimba ekugadzirisa izvi.
3. Chimiro chakaomarara chinotungamira kumutengo wepamusoro wekutenga uye kuchengetedza. Kugadzirwa kwakavhurika kunoda kuti mashambadzi akaomesesa uye gradient coil geometries, pamwe chete nemaitiro akagadziriswa emurwere. Uku kuwedzerwa kwekuvaka kuomarara kunoshandura kune yakakwirira yekutanga mutengo uchienzaniswa nekuvharirwa nzvimbo yeCylindrical yemagineti dzakaenzana. Uyezve, chimiro chisinganzwisisike chemari yakavhurika mri magnets zvinoita kuti zviome kune saiti iri mukati mechipatara zviripo pazvinhu zvakavharirwa mri mares. Kugadziriswa kwenguva refu uye Helium Real Marita zvakare inodhura nekuda kweiyo tsika yakasikwa yeiyo yakavhurika MRI Systems. Asi kune varwere vanobatsirwa kwazvo nekugadzirwa kwakavhurika, iyi mari yekuwedzera inogona kururamiswa.
Mukupfupikisa, kuvhurika kuvhurika mri scanners kukunda kusava nesimba kwetsika yakavharirwa mr masisitimu uye nekuwedzera nyaradzo yemwoyo uye kugamuchira. Ivo vanopa nharaunda ine hushamwari inotsvedza inobatsira vamwe varwere vakawanda. Nekuenderera mberi kufambira mberi, vhura MRI vanowana macortices yakafara yekushandisa, kunyanya yekufunganya, pediatric, vakwegura, uye vasina ruzivo.
