Ma MRIs onse azaka zaposachedwa atha kukhala olakwika

MRIs

Monga maginito omveka timamvetsetsa njira zamankhwala zomwe zimagwiritsidwa ntchito kuyeza zochitika muubongo ndipo imagwira ntchito, mwazinthu zina, kuchita kafukufuku wamitsempha kapena kuzindikira matenda. Mwachiwonekere, njira yomwe imagwiritsidwa ntchito kwambiri komanso yofunikira monga iyi, kungakhale kulakwitsa chifukwa a kutanthauzira molondola za zomwe zatoleredwa motero pafupifupi ma MRIs onse omwe achitika mzaka zaposachedwa atha kukhala olakwika.

Vutoli lapezeka ndi a Yogwirizanitsa University, yomwe ili ku Sweden. Kuti azindikire ndikuyesa momwe pulogalamuyo imagwirira ntchito kumasulira kwa MRI, gulu la ofufuza linayesa zotsatira mazana ambiri m'malo osiyanasiyana padziko lapansi. Mwachidule, musanapitilize kukuwuzani kuti, ngati zomwe gulu la asayansi lapeza ndizowona, zowona osachepera zaka 15 zakufufuza kwasayansi amayenera kuchotsedwa komanso pamapepala opitilira 40.000.

Ma MRIs onse omwe achitika kuyambira 1992 atha kukhala olakwika

 

Gulu la akatswiri omwe akuchita nawo kafukufukuyu ndilopanda pake ndi zotsatira zake momwe amalankhulira mpaka 70% zabwino zabodza komwe timayenera kuwonjezera maginito omwe, mwachiwonekere, angawonetse zochitika zaubongo pomwe kunalibe. Monga tanenera Anders Eklund, mutu wa ntchitoyi:

Ma MRIs ogwira ntchito ali ndi zaka 25, ndipo ndizodabwitsa njira zowerengera zofala kwambiri sizinatsimikizidwe pogwiritsa ntchito zenizeni. Apa, tagwiritsa ntchito deta kuchokera pakuwongolera kwa 499 kuti tiwunikenso magulu atatu miliyoni.

Mwachidule, ndikuuzeni kuti cholakwika opezeka mu pulogalamu ya MRI anali inakhazikika mu 2015 kotero kungatanthauze kuzindikira kuti, vuto limodzi lidalipo. Pulogalamuyi inali yoyang'anira kumasulira kwa zomwe ubongo umachita kuyambira 1992. Mosakayikira, izi zimabweretsa vuto lalikulu pakufufuza zamankhwala ndi zamitsempha, popeza maphunziro onse omwe adapangidwa kutengera zomwe zapezeka ndi pulogalamuyi zitha kukhala zolakwika. .

Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.

    Ndidawerenga chiganizo choyamba cha nkhaniyi ndipo nthawi yomweyo ndinasiya kuwerenga: «Monga maginito omveka bwino timamvetsetsa njira zamankhwala zomwe zimagwiritsidwa ntchito kuyeza zochitika muubongo ndipo, mwa zina, kuchita kafukufuku wamitsempha kapena kuzindikira matenda"

    Choyamba, sindikumvetsa kuti ndi zinthu ziti ngati izi zomwe zikuchitika pa blog. Chachiwiri, ngati simukudziwa za phunziroli, monga zikuwonekera pazambiri zomwe mumanena munkhaniyi, mutavutikira kuti mudzidziwitse pang'ono kale. Ndikosavuta kudziwa kuti zomwe ukunenazi si Magnetic Resonance, mayeso omwe samazindikira kugwira ntchito kwaubongo, koma "Functional Magnetic Resonance" (fRMN). Zikanakutengereni mphindi 5 kuti mudziwe ngati mudavutikapo pakuzifuna.
