SPECT scan (Single-Photon Emission Computerized Tomography) ni iki? Reka tubisobanukirwe mu buryo bworoshye.

Igihe muganga yakubwiraga ko ukeneye gupimwa na SPECT, wari ufite ubwoba cyangwa amatsiko? Ni ibisanzwe kumva bigoye gato iyo wumvise iri zina. "Iki ni ikizamini ki? Kizababaza? Ni iki kizaba?" Ushobora kuba ufite ibibazo byinshi mu mutwe. Ariko ntugire ubwoba. Uyu munsi, turaganira kuri iki gipimo cya SPECT mu buryo bworoshye cyane ushobora kumva. Kimwe no kuganira n'inshuti.

Mu magambo make, gupima SPECT ni iki?

Gupima SPECT ni ikizamini cyihariye cyo gupima amashusho gikoreshwa mu buvuzi bwa kirimbuzi. Ntugatinye ijambo "kirimbuzi." Rifata amashusho arambuye y'ingingo ziri mu mubiri wawe. Rikoresha ikintu cyitwa ibintu bikoresha imirasire (radiotracer) .

Tekereza muri ubu buryo. Urashaka kureba niba urugingo mu mubiri wawe rukora neza kandi niba rufite amaraso ahagije. X-ray isanzwe yerekana gusa imiterere y'ibintu nk'amagufwa. Ariko scan ya SPECT irashobora kubona inzira zibera muri urwo rugingo, cyane cyane uko amaraso atembera . Ibyo bivuze ko idashobora kubona gusa imiterere y'urugingo, ahubwo inareba uko rukora. Ni nko gutangiza moteri y'imodoka ukareba uko ikora, aho kuyireba gusa.

Ni ibihe bintu by'ingenzi birebwa muri SPECT scan?

Gupima ingingo zitandukanye hakoreshejwe uburyo bwa SPECT scan. Hari ubwoko butatu bw'ingenzi. Reka tubirebe muri ubu buryo.

Hari igihe, muganga wawe ashobora gutumiza SPECT/CT scan hamwe na SPECT scan. Ibi bihuza amakuru aturuka kuri scan zombi (SPECT na CT) kugira ngo birusheho kuba byiza.

Iyi scan ikora ite?

Hari intambwe ebyiri z'ingenzi muri scan ya SPECT. Biroroshye cyane.

1. Gutera ikintu gitera imirasire (Radiotracer) mu mubiri

Ubwa mbere, umuganga cyangwa umuhanga mu by'ubuhanga azagutera ikintu cyihariye cyitwa radiotracer mu mubiri wawe. Ibi nibyo bifasha scan gutanga amashusho asobanutse neza. Ni nko gucana itara rito kugira ngo ubone ikintu mu cyumba cyijimye.

• Akenshi, ibi bitangwa nk'urushinge mu mitsi.
• Mu bihe bidasanzwe, iki kintu gishobora kunyobwa cyangwa guhumekwa.

Uko iyi ""(radiotracer)"" igenda mu mubiri, irunda mu rugingo cyangwa mu ngingo zisuzumwa. Uburyo irunda butuma muganga asobanukirwa uko urwo rugingo rukora.

2. Gufata amafoto ukoresheje kamera ya gamma

Nyuma yuko umubiri wawe umaze kwinjiza icyo kintu cyihariye, ujyanwa mu cyumba kirimo scanner. Aho ngaho, uryamishwa ku meza. Hanyuma, kamera yihariye yitwa kamera ya gamma irazenguruka buhoro buhoro ikagufata amafoto.

Iyi kamera ya gamma imeze nk'icyuma gipima imirasire. Ntabwo isohora imirasire, ahubwo ifata ibimenyetso bivuye kuri radiotracer iri mu mubiri wawe. Hanyuma yohereza ayo makuru kuri mudasobwa, igashushanya ingingo zawe mu buryo bwa 3D.

Ni gute nakwitegura mbere yo gupimwa?

Muganga wawe azaguha amabwiriza yihariye, ariko muri rusange, wibuke ibi bintu.

• Imyenda: Ambara imyenda ijyanye n'igihe kandi idafite ishingiro.
• Imitako: Ni byiza gukuramo imitako y'icyuma nk'amasaha, imikufi, n'imiringa hanyuma ukayisiga mu rugo mu gihe ugiye gupimwa.

Hari igihe inshinge ya `(radiotracer)` iterwa mbere gato y'uko ipimwa. Ariko mu bizamini bimwe na bimwe, ishobora gutangwa amasaha make cyangwa iminsi mike mbere . Niba hari ikintu nk'icyo gikenewe, muganga wawe azabikumenyesha mbere y'igihe.

Ni iki kibaho mu gihe cyo gupima?

Ubusanzwe gupima iminota 30. Ariko, bitewe n'igice cy'umubiri kiri gupimwa, bishobora gufata igihe kirekire. Icyo ugomba gukora ni ukuryama ku meza gusa. Ntuzumva ububabare muri iki gikorwa. Igipima ntikizagukora ku mubiri wawe.

Nyuma y'uko ikizamini kirangiye, ushobora gutaha nta kibazo ugakomeza imirimo yawe isanzwe.

Ni izihe nyungu zo gukoresha SPECT scan?

• Ubu buryo bwo gusuzuma bushobora kandi gukorwa ku bantu bafite ibikoresho by'umutima nka pacemakers.
• Ishobora kumenya indwara zimwe na zimwe zihishe izindi scan zidashobora kubona.
• Ntitwiga gusa imiterere y'ingingo, ahubwo tunamenya imikorere yazo .

Ese hari ingaruka cyangwa ibyago bishobora guterwa n'iyi ndwara?

Isuzuma rya SPECT rikoresha imirasire mike cyane, bityo ingaruka ni nke. Nta mpamvu yo kubihangayikisha. Ariko, niba ufite ikibazo cyangwa impungenge ku mirasire, vugana na muganga wawe ku mugaragaro.

Ni irihe tandukaniro riri hagati ya SPECT, CT na MRI scans?

Abantu benshi bahura n'urujijo kuri ubwo bwoko bwa scan. Reka dusobanukirwe itandukaniro rikomeye riri hagati yabwo.

Muri make, CT na MRI scan ni nko gufata 'ifoto' y'ibice by'umubiri. Ni ukuvuga ko bareba ibintu nk'imiterere n'ingano yabyo. Ariko SPECT scan ni nko kureba 'videwo' , itanga amakuru y'uko ibyo bice bikora .

Bifata igihe kingana iki kugira ngo ubone ibisubizo?

Ubusanzwe bifata icyumweru kimwe kugira ngo ubone ibisubizo by'isuzuma ryawe.Ushobora kugenda. Amashusho yo muri scan asuzumwa neza na radiologist hanyuma hagategurwa raporo. Hanyuma raporo yoherezwa kwa muganga wagutegetse ikizamini. Amaherezo, muganga wawe azasuzuma raporo, aganire nawe ibyavuye mu bushakashatsi, hanyuma afate icyemezo cy'ibindi bikorwa, niba hari icyo bikenewe.
