Canllaw ar MRI a rôl technoleg mewn meddyginiaeth fodern.

Mae'r dudalen hon dros 1 oed. Byddwch yn ymwybodol oherwydd bod amser wedi mynd heibio, gall y wybodaeth a roddir ar y dudalen hon fod wedi dyddio neu fod yn anghywir, ac mae'n bosibl na fydd y safbwyntiau neu'r barnau a fynegir yn berthnasol mwyach. Mae'n bosibl na fydd rhai elfennau technegol, megis deunydd clywedol a gweledol a chyfryngau rhyngweithiol yn gweithio bellach. Am fwy o fanylion, gweler sut rydym yn delio â chynnwys hŷn.

Sganwyr MRI (delweddu atseiniol magnetig) yw un o’r adnoddau diagnostig gorau a ddefnyddir heddiw. Cânt eu defnyddio i greu delweddau mewnol o’r tu mewn i’r corff dynol – heb fod angen llawdriniaethau neu belydrau-X.

Yn y fideo hwn, mae arbenigwyr yn Academi Chwaraeon Coleg Castell-nedd Port Talbot yn egluro sut mae technoleg MRI yn gweithio, sut mae’n helpu i wneud diagnosis o anafiadau a salwch, a pham ei bod yn arbennig o bwysig ym myd gwyddorau chwaraeon a gofal iechyd.
