He aha te mea te pikitia o te MRI? E tātaritanga MRI?

Tātaritanga o maha mate tino uaua e te meka e i roto i te tikanga ki te tika te whakatau i te raruraru, kite nga āhuatanga o huringa kiko waho, huringa i roto i tona hanganga. I roto i ngā take pēnei, ko te tikanga pai mo te tātaritanga he hāngai autō atahanga (MRI).

He aha te atahanga te kōwarotanga autō

Kitenga e MRI ko te tino noa i teie mahana no te mea taea reira ki a koe sioloto tata katoa nga whekau, me te kitea huringa hanganga i roto i te kopa, me whekau; I roto i ngā, pikitia paparanga o te MRI roro ko te tino mōhiohio, me te tino āwhina i roto i te tātaritanga o te pukupuku intracranial o mate pukupuku, patunga (whai wāhi ngā tino ki te kite i te pokapū i roto i te hemorrhagic patunga) me te mate iaia (aneurysms malformations ranei); He tika, me i kino whara roro pāmamae MRI.

painga o te tikanga

MRI fakatahai te aritanga me whakaaturanga, engari i te wa kotahi, me te haumaru hoki te manawanui.

Ko te painga te whakakorekore o MRI ko e ko te reira mārama e taea te whiwhi taua pikitia taipitopito taipitopito o whekau, me te kopa, kahore te whakamahi o ngā rauemi rerekē.

Heoi, i roto i ētahi wā, mo te mātakitaki atu taipitopito o te rerekē whakarei ake ko whakamahia; i roto i te ngā, ko reira hāngai ka te ako o te māuiuitanga iaia kaka. Pictures o te MRI roro ki te rerekē, ko te nui o ngā mōhiohio i roto i whakapeka disorders circulatory kaka, mai hanga ratou e taea ki te ahu mai i te taumata o te whara oko, me te taha tangohia o te arotahi pathological.

Nahea te matawai

I raro i te mana o te oscillations autō te huri whanonga o te ngota hauwai, mai ke te aratau nekehanga kei te pai whakatupato matūriki i te karihi o te ngota hauwai. I tukuna te whakamutunga o te pūngao kaupapa te, whakaritea pūrere.

hāngai ana te tikanga MRI tātaritanga mahi i runga i ari autō o te kōwarotanga. Ko te parau tumu o te mahi o te taputapu tātaritanga, me te kei i roto i te huringa o tohu irirangi i roto i te pikitia. He tohu irirangi whiwhi i liliu spectrometer te kōwarotanga autō.

Nā ki te āhuatanga o ngā ngota hauwai, he taea te ihirangi o nei i roto i te tinana tangata tae tekau ōrau o taua tātaritanga waho te kino iti ki te hauora.

Kua whiwhi image rite, kei te tātarihia tākuta tohunga o te kōtaha hāngai o te whakapakoko hua, whakaritea ki te täkupu me te kitea huringa pathological.

aratuka History

I kitea te āhuatanga o te te kōwarotanga autō karihi me te whakaahuatia ake i roto i te waenganui o te rautau rua tekau - i roto i te 1946. A mo te wa tuatahi ki te whiwhi i te whakapakoko ki te awhina o muri reira i roto i 1973 tenei hangarau.

Kia pehea te ko te rangahau

Waho, te taputapu mo te whakaahua te kōwarotanga autō rite rawa te ngongo roa kuiti titiro.

A, no te whakanohoia i roto i te whare ako manawanui te whakamahi i te moenga motuhake.

Mai te roanga o noho o te manawanui i roto i te kōwae, ko te tino nui - ki runga ki te wha tekau meneti, me i roto i te tahi mau take kino - ara atu tikanga mo te noho o te manawanui i roto i te "ngongo" kia rite whakamarie rite taea. Roto te pūrere tautoko e te marama te peroo me ventilation, nui ki te whakarite i te manawa ata. Ko reira whakahauanga i roto i te kōwae me hei kōrero ki te whakahaere i te pātene kaiwhakahaere he rangahau.

whakangungu

• e kore e MRI tukanga kia whakamana i runga i te puku tonu.
• I mua i te tukanga, me tango te rangahau manawanui ahanoa whakarewa katoa (mataaratanga, whakapaipai, hairpins, niho more).

I roto i te tukanga, kua ki te takoto rite tonu rite taea rite te whakapakoko rangahau i hanga te te manawanui; a me pehea ka waiho ai mārama, tātaritanga tika atu me te pai i pai ai. Na reira, i roto i te wā i reira i reira he he hiahia ki te kawe i roto i ako tomographic o te tamaiti iti ki a ia i roto i te matawai, me te e takoha tohunga ki te tuu i tona whaea.

hua rangahau

scan MRI - he raupapa o whakapakoko, e he whakapakoko paparanga o whekau.

He rite Hua ako tomographic, te tikanga i roto i te torutoru haora i muri i te tukanga tātaritanga.

Ka whiwhi te manawanui i te ringa o te pikitia tā o te MRI, e whakaatu ana te taketake, whakapakoko matua, a ka hanga i te whakaaro ngaio.

Hoki te haratau, i roto i te maha ngā take, i homai te manawanui ko te ringa rite ki puku katoa, kaore he aweretanga, nga whakapakoko whiwhi i roto i te tukanga. Ko te tino nui i roto i te wā i reira ko te manawanui i roto i te heke mai ka tono mō te wetemuna te raraunga riro i roto i te tātaritanga o te tahi atu ngaio tenei mita.

Tuhinga mō te atahanga

āwhina ana tēnei tikanga ki te nui rawa o te tika ki te sioloto te mana, me te hanganga:
