MRI zobuchopho - ithuba ukubheka uqobo kusuka ngaphakathi

Magnetic resonance imaging (noma i-MRI) zobuchopho, skeleton kanye nezinye izitho njengoba indlela ucwaningo ithambo izicubu kuliragelo okunengqondo luhlolo-X-ray kanye imaging usebenzisa ikhompyutha. Sekuyiminyaka engaphezu kweyikhulu edlule, ukucwaninga kwezokwelapha kuye kwabonisa ukuthi kungenzeka ukubheka ngaphakathi emzimbeni womuntu, uma bengakwazi ukusizakala Izakhiwo ugongolo-X-ray. Impahla lokuqala: at nombono ugongolo mufushane kunaleyo wave ukukhanya. Okwesibili, ugongolo-X-ray uyakwazi ukungena izicubu. kwezicubu balo bubanzi ukuncela, kubonise esithambile. Esikhathini isithombe sibonwa ekugcineni kuba amathambo, amazinyo, esifubeni.

tomography ngekhompyutha yasungulwa ngemuva yethula kwezokwelapha imishini computer. Lolu cwaningo kuyafana X-ray. it is kuphela aphethwe ezihlukahlukene izinzwa eqondisa X-ray abonise ezindaweni ezimbalwa ngesikhathi esifanayo, njengoba uma ukusika target isitho zibe tincetu eziningi. Le ndlela kusisiza ukubona Sakhiwo sangekhatsi ithambo esigabeni futhi ngokuningiliziwe. Zonke izithombe kuthiwa ngobulili kuyi-computer, lapho kungaba ngokucophelela futhi okudliwa ukuhlola onguchwepheshe.

Nokho, njengoba x ray nakuma-CT scan aveza izithombe kwenza umuntu ngemisebe futhi umuntu eside. Ngenxa yalokho, kungaba avuse ukuguquka kwezakhi zofuzo emzimbeni futhi kungaholela ekwakhiweni zamangqamuzana omdlavuza. nemibi okunjalo kwama-X ray ukhuthaze odokotela kanye ososayensi ukufuna izindlela ephephile zocwaningo zomzimba womuntu. Ngakho, lapho etadisha ngokujulile wemithetho yemvelo nokuthuthukisa ubuchwepheshe obusha sezishiye ukuvela ngo-1973 we indlela entsha.

Ngesisekelo kakade ngingabeki ngemisebe ye-X ray, futhi izakhiwo kazibuthe kanye namagagasi omsakazo. Isithombe esikrinini ngesikhathi MRI zobuchopho, kanye nezinye amathambo izicubu etholwe umphumela-nucleus ye-athomu ye-hydrogen oyingxenye ithambo kophenyo echayeke emisebeni kagesi imvamisa ehlukene. Ayephila ubungako bamandla obusuka core njengoba esimweni ujabule, futhi ngokuphazima kweso zokuzilibazisa. Konke lokhu kwaziswa kufakwa kukhompyutha, usebenzisa ubuchule obuphezulu zezibalo okwenziwa - nesihenqo ubonisa isithombe esinembile kakhulu izingqimba eziningana ithambo, noma yimuphi umgwamanda.

Lokhu uphethwe ivumela odokotela ukuba bahlolisise ngokuningiliziwe futhi bahlonze izifo kwezitho zangaphakathi, okuyizinto ezahlukene asikwazi ukuhlolwa. Njengoba kunzima kakhulu ukubheka ngaphakathi Yekhanda, kukhona eyodwa kuphela indlela eqinisekile ukuhlola izicubu zomzimba ezithambile ngaphakathi kwaso - kuyinto MRI zobuchopho. Lapho futhi uya kanjani?

Kuyini MRI zobuchopho? Lena inqubo silula ukuze isiguli. Vele ukuya isithwebuli - isithwebuli emincane izinzwa. Ukuqamba Amanga kusadingeka imizuzu eyishumi amathathu. Ngenxa yale njongo, angabawa ezizofakwa imikhono, imilente, esifubeni, ekhanda sekhiba ekhethekile ukuze kukhawulwe ukuhamba umzimba. Ngokuyinhloko scanner ngempela ewumngcingo, kungaba ibakhathaze. Ngezinye izikhathi, ezinye iziguli kuhlanganisa i kuhlasela ukwethuka phakathi nesifundo. Ngenxa yalesi sizathu, we developed evulekile MRI Enani.

Kwaziwa kahle kamhlophe ukuthi metal nezinto zegolide kakhulu sensitive kazibuthe kakhulu, ngakho-ke ngesikhathi sokuhlolwa enemininingwane yezitho ezinjalo kusukela nesineke akufanele kube emzimbeni, futhi kulelo gumbi. Zonke izinto zokuhloba, izinkinobho, futhi yenza-up kufanele kususwe phambi test. Kungenxa yezizathu ezifanayo nezethu, i-MRI zobuchopho noma ezinye izinhlaka asikwazi ukwenziwa kulabo iziguli lezi zitho, elawula ukushaya kwenhliziyo noma yimuphi omunye izimila metal.

Eminyakeni yamuva, liye kabanzi ingqondo MRI nge umehluko. Ingqikithi yalo ndlela ukuthi isiguli kuthatha phambi ejenti cwaningo umehluko. Inikeza ithuba lokubheka isimo izitsha ezahlukene ubuchopho kanye nokusakazwa igazi nganoma iyiphi isimo. Ezinye iziguli kungaba ukusabela iguliswa into. Futhi, mhlawumbe, umonakalo kuphela ongaletha umuntu uhlobo uphethwe. Ngokuvamile, i-MRI siyasebenza kakhulu uzingela izifo, kufihlwe ngemuva ithambo.
