Icyo Gallium-68 DOTATATE ari cyo: Ibikoreshwa, Uburyo Bwo Gukoresha, Ingaruka Zirukana n'ibindi

Gallium-68 DOTATATE ni umuti wihariye ukoreshwa mu gufasha abaganga kubona ubwoko bumwe na bumwe bwa kanseri mu mubiri wawe mugihe cyo gukoresha imashini zifashisha amashusho. Tekereza nk'urumuri rwihariye rufasha ikipe yawe y'ubuvuzi gushaka no gusuzuma selile za kanseri zidasanzwe zishobora kuba zigoye kubona.

Uyu muti ukorana n'itsinda ryitwa radiopharmaceuticals, bivuze ko ihuriza hamwe umubare muto w'ibintu bifite imirasire hamwe n'ikintu kigamije. Igice gifite imirasire gituma kamera zidasanzwe zifata amashusho arambuye y'ingingo zawe z'imbere, mugihe igice kigamije gishakisha selile za kanseri zidasanzwe zifite ibintu byihariye ku ruhu rwazo.

Gallium-68 DOTATATE ikoreshwa kubera iki?

Gallium-68 DOTATATE ikoreshwa cyane cyane mugushakisha no gukurikirana ibibyimba bya neuroendocrine (NETs) mugihe cyo gukoresha PET scans. Ibi nibibyimba bikura mumisemburo itanga selile, kandi bishobora kuboneka mubice bitandukanye byumubiri wawe harimo pancreas yawe, amara, ibihaha, cyangwa izindi ngingo.

Umuvuzi wawe ashobora kugusaba iyi scan niba ufite ibimenyetso bivuga ko ufite igishyitsi cya neuroendocrine, cyangwa niba waramaze kumenyekana kandi ukeneye gukurikiranwa. Uyu muti ufasha gukora amashusho asobanutse yerekana neza aho ibi byishyitsi biherereye kandi uko byitwara mugihe cyo kuvurwa.

Ubu buhanga bwo gukoresha amashusho bufite agaciro kanini kuko ibibyimba bya neuroendocrine akenshi bifite ibintu byihariye byitwa somatostatin receptors ku ruhu rwabo. Igice cya DOTATATE cyumuti cyagenewe guhuzwa n'ibi byakira, bituma ibibyimba byaka kumashusho ya scan.

Gallium-68 DOTATATE ikora ite?

Gallium-68 DOTATATE ikora mugushaka ibintu byihariye kuri selile za kanseri, kimwe n'urufunguzo rwinjira muri lock. Uyu muti unyura mumaraso yawe ukifatanya na somatostatin receptors zisanzwe ziboneka kuri selile za kanseri ya neuroendocrine.

Iyo umuti umaze kwifatanya n'izo reseptori, gallium-68 itanga ubwoko bw'imirasire yitwa positrons. Izo positrons zifatanya na electrons mu mubiri wawe, zigakora ibimenyetso scanner ya PET ishobora kumenya no guhindura mu mashusho arambuye.

Uburyo bwose buragoye ariko bikaba vuba mu mubiri wawe. Gallium-68 ifite imirasire ifite igihe gito cyo kubaho cy'iminota nka 68, bivuze ko igabanya imirasire vuba nyuma yo guterwa urushinge.
