Bone scintigraphy kuongororwa kwekufungidzira kwekufungidzira kunoshandiswa, kazhinji, kuongorora kugoverwa kwemapfupa ekuumba kana kugadzirisa basa mukati memafupa, uye nzvimbo dzekuzvimba dzinokonzerwa nehutachiona, arthritis, kutsemuka, shanduko mukutenderera kweropa zvinogona kuzivikanwa. prostheses kana kuongorora zvinokonzeresa marwadzo emapfupa, semuenzaniso.

Kuita muyedzo uyu, radiopharmaceutical yakadai seTechnetium kana Gallium, inova zvinhu zvine radioactive, inofanirwa kujekeswa mutsinga. Izvi zvinhu zvinokwezva kune bone tishu pamwe nechirwere kana chiitiko mushure memaawa maviri, ayo anogona kunyoreswa achishandisa yakakosha kamera, inoona radioactivity uye inogadzira mufananidzo wemafupa.

Zvinoitwa sei

Bone scintigraphy inotangwa nejekiseni kuburikidza neiyo radiopharmaceutical vein, iyo kunyangwe iri radioactive, inoitwa mune yakachengeteka dosi yekushandisa muvanhu. Ipapo, munhu anofanira kumirira nguva yekutorwa kwechinhu nemapfupa, zvinotora anenge maawa 2-4, uye munhu wacho anofanirwa kurairwa pamuromo wemvura pakati penguva yejekiseni redhiopharmaceutical uye kuwana mufananidzo.

Mushure mekumirira, murwere anofanirwa kuita weti kuti abudise dundira uye avate pakamubhedha kuti atange kuongorora, kunoitwa mune yakakosha kamera iyo inorekodha mifananidzo yemasaga pamakomputa. Nzvimbo dzinotariswa zvakanyanya ne radiopharmaceutical zvakanyanya, zvinoreva kushanduka kwemagetsi munzvimbo iyi, sezvakaratidzwa mumufananidzo.

Iyo bvunzo yekuongorora bone inogona kuitirwa dunhu chairo kana yemuviri wese uye, kazhinji, bvunzo rinogara pakati pemaminitsi makumi matatu kusvika makumi mana. Murwere haadi kutsanya, kutora chero hanya, kana kumisa mushonga. Zvisinei, mumaawa makumi maviri nemana anotevera bvunzo, murwere haafanire kusangana nevakadzi vane nhumbu kana vacheche, sezvo vangave vane hanya neiyo radiopharmaceutical inobviswa panguva iyi.

Uye zvakare, kune matatu-chikamu chefupa scintigraphy, inoitwa kana ichidikanwa kuongorora mifananidzo yeiyo scintigraphy muzvikamu. Nekudaro, muchikamu chekutanga kuyerera kweropa muzvimiro zvemabhonzo kunoongororwa, muchikamu chechipiri kuyerwa kweropa muchimiro chemapfupa kunoongororwa uye, pakupedzisira, mifananidzo yeiyo radiopharmaceutical inotorwa nemapfupa inoongororwa.

Chii ichochi

Bone scintigraphy inogona kuratidzwa kuti izive mumamiriro ezvinhu anotevera:

• Bone scintigraphy: kutsvagisa kwemastastases emapfupa anokonzerwa nemhando dzakasiyana dzekenza, senge zamu, prostate kana mapapu, semuenzaniso, uye kuona nzvimbo dzekuchinja mupfupa metabolism. Zvirinani nzwisisa kuti chii chinonzi metastases uye kana zvikaitika;
• Nhatu-Phase Bone Scintigraphy: kuziva shanduko dzinokonzerwa neosteomyelitis, arthritis, yekutanga mapfupa mapundu, kushushikana kwekutsemuka, kupunzika kwakavanzwa, osteonecrosis, Reflex yekunzwira tsitsi dystrophy, bone infarction, bone graft kushanda uye kuongorora kwemapfupa epfupa. Iyo zvakare inoshandiswa kuongorora zvinokonzeresa zvekurwadziwa kwepfupa umo zvikonzero zvisina kuzivikanwa pamwe nedzimwe bvunzo.

Bvunzo iyi inopesana yevakadzi vane nhumbu kana panguva yekuyamwisa, uye inofanirwa kuitwa chete mushure mekurairwa navanachiremba. Mukuwedzera kune bone scintigraphy, kune mamwe marudzi e scintigraphy anoitwa pane akasiyana mitezo yemuviri, kuti aone zvirwere zvakasiyana. Tarisa uone zvimwe muScitigraphy.

Maitiro ekunzwisisa mhedzisiro

Mhedzisiro ye bone scintigraphy inopihwa nachiremba uye kazhinji inove nemushumo unotsanangura izvo zvakaonekwa uye mifananidzo yakatorwa panguva yekuongorora. Paanenge achiongorora mifananidzo, chiremba anotsvaga kutarisa matunhu anonzi anodziya, ayo ari iwo ane ruvara rwakanyanya kuoneka, zvichiratidza kuti imwe nharaunda yebhonzo yatora mwaranzi yakawanda, zvichiratidza kuwedzera kwezviitiko zvemuno.

Nzvimbo dzinotonhora, idzo dzinoonekwa sedziri pachena mumifananidzo, dzinoongororwawo nachiremba, uye zvinoratidza kuti pakange paine kunwa kushoma kweradiopharmaceutical nemapfupa, izvo zvinogona kureva kudzikira kweropa panzvimbo iyi kana kuvapo semota isina njodzi, semuenzaniso.
