Elastography ndi Mmene Zimathandizira Kufufuza Kanseri Yamatenda

Kodi elastography ndi gawo lotani lomwe lingayambe kuwonetsetsa khansa ya m'mawere?

Musanayambe khansa ya m'mawere , muyenera kuigwiritsa ntchito. Kuzindikira khansa ya m'mawere kumayambiriro kungapulumutse miyoyo ndi kuchepetsa kusadulidwa ndi matenda omwe nthawi zambiri amatsatira chithandizo.

Kodi Elastography N'chiyani?

Choncho, kwa zaka zambiri, ofufuza ayesera kupeza njira zabwino zowononga khansa ya m'mawere. Mu 1980, akazi pafupifupi anayi pa asanu alionse amene anadwala khansa ya m'mawere adapeza mtanda wokha. Ngakhale kuti kudzifufuza kwa m'mawere kuli kofunikira, ambiri amatha khansa ya m'mawere amapezeka pamene mayi ali ndi mammogram , ultrasound kapena MRI (maginito imaging resonance).

Matumbo a Chifuwa ndi Mabotolo a Benign

Koma ngakhale pamene mayesero amavumbula mtanda wodandaula, njira yokhayo yomwe amavomereza lero kuti apeze ngati ali ndi khansa ndiko kuchita chifuwa cha m'mawere . Kujambula kwa Ultrasound ndi MRI kungathe kuzindikira kuti khansa yaying'ono m'mayi ena imakhala bwino kusiyana ndi mamemogram, koma imasonyezeranso kuti ndi zilonda zoopsa komanso zowopsa.

Ichi ndi chimodzi mwa zifukwa zomwe zili pafupi ndi zina zisanu ndi zisanu za m'mawere za m'mawere zimasonyeza kuti malo omwe akukayikirawo anali abwino . Mwa kuyankhula kwina, 80% ya biopsies amafunika kokha kuti athetse khansa.

Kuchita opaleshoni kumakhudzana ndi biopsies ndi kofunika ndipo kumaphatikizapo zoopsa zake. Choncho, kwa zaka zambiri, amayi ndi madotolo awo akuyembekezera chiyeso cha matenda omwe amatha kupeza malo okayikitsa mkati mwa bere ndikuuza ngati ayi ndi khansa, popanda opaleshoni yosautsa. Pambuyo pa kafukufuku wopitirira zaka makumi awiri, njira yatsopano yolonjezedwa yotchedwa elastography ingakhale yokonzeka kukwaniritsa chiyembekezo chimenecho.

Elastography - Ikugwira Ntchito Motani?

Elastography imagwirizanitsa zamakono zamakono zamakono opanga zojambulajambula ndi mtundu wakale kwambiri wa matenda a khansa ya m'mawere: kuthandizani . Mayi kapena dokotala akamapitiriza kuyamwa pamatenda kuti amve zovuta zachilendo, amakhudza bere ndi pang'ono. Mphamvu imeneyi imachititsa kuti mawere azisunthira m'njira. Mawu oyenerera kuti njira yowongoka imakhudzidwe ndi mphamvu imatchedwa elasticity. Ngati munayamba mwawona chifuwa ndi chotupa cha khansa pamwamba pa kukula kwake, mumadziwa kuti chotupachi chimakhala ngati chotupa cholimba, chofanana ndi thanthwe kapena pichesi. Asayansi amanena kuti zotupa za khansa zimakhala zochepa kwambiri - sizimasintha mawonekedwe mosavuta. Ndi katundu amene amathandiza elastography kugwira ntchito.

Kitchen Science Demonstration - Kodi Elastography Zimagwira Ntchito Bwanji?

Kuti tifotokoze mmene elastography imagwirira ntchito, tinapita ku khitchini ndipo tinapanga mtundu wa Jell-O ® wobiriwira, lalanje, laimu, mandimu, ndi zokometsera za sitiroberi, onse okhala ndi mitundu yosiyanasiyana. Timayika mandimu pakati pa mandimu ndi sitiroberi kuti ziyimire chinthu chovuta monga chotupa.

Fufuzani lotsatira lotsatira kuti muwone zomwe zimachitika.

Elastography - Kuwuza Apart Benign ndi Matenda Aakulu

Elastography Chiwonetsero chapitirira

Tikachotsa gelatin mu nkhungu ndikuchiyika pamtengo, zigawozo zinapanga mizere yabwino kwambiri yopanda kanthu:

Amondi samasintha mawonekedwe (ngati akuwoneka ngati akutero, ndi chifukwa cha kupotoka kwa magetsi kudzera mu gelatin). Koma zowonjezereka (zotupa) gelatin zimagwedezeka pansi pa zovuta chifukwa ndi zotanuka kwambiri kuposa amondi.

Kodi Elastogram Yachita Bwanji?

Kuti atenge "elastogram" ya m'mawere, choyamba makina opangidwa ndi ultrasound opangidwa bwino amapanga mawere . Zomwe zimachitika pachifuwa cha m'mawere zimakhala ndi zinthu zochepa zomwe zimapezeka muzithunzi za ultrasound, ndipo izi zimagwira ntchito ngati zizindikiro za zomwe zikubwera motsatira. Ngati pali zowonongeka, izi ziwonetsanso, koma pakalipano fano la ultrasound silinena kwa dokotala china chilichonse choposa chakuti pali zipsera zokayikitsa, zomwe zimapangitsa kuti mamemograms achite.

Gawo lovuta likubweranso. Kachilombo kochepa kamagwiritsidwa ntchito pa bere, kokwanira kuti lizisunthira pang'ono. (Kupanikizika kumeneku mwina ndi kochepa kwambiri kuposa momwe mumalandira pamene mabere anu akuwombedwa kuti mutenge mammogram ochiritsira.) Ndizovuta kugwiritsidwa ntchito (kuganiza "supuni pamwamba pa gelatin"), dongosolo limatenga chithunzi china cha ultrasound. Kenaka, pulogalamu ya pakompyuta imafananitsa zithunzi ziwirizo ndipo imapanga mapu omwe amasonyeza kuti zigawo zosiyana ndi zotani. Mapu awa, otchedwa elastogram, ndi othandiza kwambiri powulula zipsinjo zovuta, zomwe zimakhala zosautsa. Mitengo yomwe imasintha kwambiri imakhala yowopsya.

Elastography - Zotsatira ndi Tsogolo la Kufufuza kwa Khansa ya M'bwere

Ochita kafukufuku m'mayiko osiyanasiyana ku Ulaya ndi ku United States apanga njira zopangira khansa ya m'mawere ndi zolinga zina kuyambira kumayambiriro kwa zaka za m'ma 1990. Njira ziwiri zoyambirira zimatchulidwa kuti compress based based elastography (kapena dzanja laulere) ndi mafunde a shear elastography.

M'maphunziro angapo, njira izi zatha kudziwa pamene chotupacho chikanakhala choipa pa nthawi ya 90%. Pakhala pali ziphuphu zochepa (pamene chotupa chochititsa manyazi chikuwoneka choipa) ndi zolakwika zabodza (pamene chotupa chikuwoneka chachilendo ndipo kwenikweni ndi khansa). Pali vuto lina lakuti mawere "ofewa" monga khansa ya mucinous imayambitsa zolakwika, komanso "zovuta" zotupa za m'mawere monga fibrous adenomas zimayambitsa zonyenga, ndipo malingalirowa akukalikiridwabe.

Kawirikawiri, maphunziro mpaka lero akuwoneka otsimikizika kwambiri, ndi kuwonanso kwaposachedwa kwa zolemba zomwe zatsimikizira kuti kugwiritsa ntchito elastography kungathandize kutsogolera njira yosiyanitsira zipsera zoyipa ndi zosautsa m'tsogolo.
