Gukoresha CT scanning muri urology

Gupima indwara z’inkari ni ingenzi cyane kugira ngo byunganire amakuru y’ubuvuzi no gushyigikira abaganga b’inkari mu gushyiraho uburyo bukwiye bwo kuvura umurwayi. Mu buryo butandukanye bwo gupima, gupima hakoreshejwe ikoranabuhanga (CT) ubu bifatwa nk'icyitegererezo cyo gusuzuma indwara z’inkari bitewe n’uko ziboneka cyane, igihe cyo gupima vuba, n’isuzuma ryuzuye. By’umwihariko, gupima hakoreshejwe ikoranabuhanga (CT urography).

AMATEKA

Mu bihe byashize, uburyo bwo gupima urography mu mitsi (IVU), buzwi kandi nka "excretory urography" cyangwa "intravenous pyelography," bwakoreshwaga cyane cyane mu gusuzuma inzira y'inkari. Ubu buryo bukoresha radiography ya mbere isanzwe hanyuma hagakurikiraho gutera umuti ugabanya ubukana bw'amaraso mu mitsi (1.5 ml/kg y'uburemere bw'umubiri). Nyuma yaho, haboneka amashusho menshi mu gihe runaka. Inzitizi nyamukuru z'ubu buryo zirimo gusuzuma ibice bibiri no kubura isuzuma ry'imiterere y'umubiri wegereye.

Nyuma yo gukoresha uburyo bwa "computer tomography", IVU yatangiye gukoreshwa cyane.

Ariko, mu myaka ya 1990 gusa, ubwo hatangizwaga ikoranabuhanga rya helical, igihe cyo gusuzuma cyarihutaga cyane ku buryo ibice binini by'umubiri, nk'inda, byashoboraga kwigwa mu masegonda make. Ubwo habonekaga ikoranabuhanga rya multi-detector mu myaka ya 2000, uburyo bwo gusuzuma imiterere y'aho umuntu aherereye bwarazamuwe, bituma hamenyekana urothelium yo hejuru y'inkari n'uruhago, maze hashyirwaho CT-Urography (CTU).

Muri iki gihe, CTU ikoreshwa cyane mu gusuzuma indwara z’inkari.

Kuva mu ntangiriro za CT, byari bizwi ko spectra ya X-ray y'ingufu zitandukanye ishobora gutandukanya ibintu bifite imibare itandukanye ya atome. Ni mu 2006 gusa iri hame ryakoreshejwe neza mu kwiga ingingo z'umuntu, amaherezo bituma sisitemu ya mbere ya CT ifite ingufu ebyiri (DECT) ishyirwa mu bikorwa rya buri munsi. DECT yahise igaragaza ko ikwiriye mu gusuzuma indwara z'inzira y'inkari, kuva ku kwangirika kw'ibikoresho mu nkari kugeza ku gufata iyode mu ndwara za kanseri zo mu nkari.

inyungu

Uburyo bwa gakondo bwo gukoresha CT busanzwe burimo amashusho ya precontrast na multiphase postcontrast. Imashini zigezweho zo gupima CT zitanga amakuru menshi ashobora kongera gukoreshwa mu byiciro bitandukanye kandi afite ubugari butandukanye, bityo agakomeza kuba meza cyane mu ishusho. CT urography (CTU) ishingiye kandi ku ihame rya polyphasic, yibanda ku gice cyo "gusohora" nyuma y'uko contrast agent imaze kwinjira mu buryo bwo gukusanya no mu ruhago, ahanini ikora IV urogram ifite contrast nziza cyane.

UMUBARE

Nubwo tomography ya computed-enhanced ari yo ikoreshwa mu gupima inzira y'inkari bwa mbere, imbogamizi zirimo zigomba kwitabwaho. Kugaragara mu mirasire no kuvura indwara ziterwa n'imirasire bifatwa nk'imbogamizi zikomeye. Kugabanya urugero rw'imirasire ni ingenzi cyane, cyane cyane ku barwayi bakiri bato.

Ubwa mbere, hagomba kwitabwaho ubundi buryo bwo gufata amashusho nka ultrasound na MRI. Niba ubwo buryo budashobora gutanga amakuru asabwa, hagomba gufatwa ingamba hakurikijwe protocole ya CT.

Isuzuma rya CT rikozwe mu buryo bwa "Contrast-enhanced CT" ntirikwiye ku barwayi bafite ubwivumbure ku bintu bitera imirasire y'impyiko ndetse n'abarwayi bafite ikibazo cy'imikorere y'impyiko. Kugira ngo bigabanye nephropathy iterwa n'impinduka, abarwayi bafite igipimo cyo kuyungurura glomerular (GFR) kiri munsi ya 30 ml/umunota ntibagomba guhabwa "contrast media" batabanje gusuzuma neza ingaruka n'inyungu, kandi bagomba gukoresha witonze ku barwayi bafite GFR iri hagati ya 30 na 60 ml/umunota mu barwayi.

IBY'AHAZAZA

Muri iki gihe gishya cy’ubuvuzi bugezweho, ubushobozi bwo gusesengura amakuru y’imibare aturutse ku mashusho ya radiyo ni ikibazo kiriho ubu n’ejo hazaza. Ubu buryo, buzwi nka radiyomike, bwavumbuwe bwa mbere na Lambin mu 2012 kandi bushingiye ku gitekerezo cy’uko amashusho y’ubuvuzi akubiyemo ibintu bishobora kugaragaza imiterere y’umubiri w’umuntu. Gukoresha ibi bipimo bishobora kunoza gufata ibyemezo by’ubuvuzi no kubona umwanya cyane cyane muri kanseri, bigatuma, urugero, hapimwa ibidukikije bya kanseri kandi bigahindura uburyo bwo kuvura. Mu myaka mike ishize, hakozwe ubushakashatsi bwinshi ku ikoreshwa ry’ubu buryo, ndetse no mu isuzuma rya kanseri y’umura, ariko ibi biracyari uburenganzira bw’ubushakashatsi.

LnkMed ni ikigo gitanga ibicuruzwa na serivisi ku rwego rwa radiyo mu nganda z'ubuvuzi. Inshinge zikoresha umuvuduko mwinshi ziciriritse zakozwe kandi zigakorwa n'ikigo cyacu, harimoInshinge imwe ya CT,Inshinge ya CT ifite imitwe ibiri,Inshinge za MRInainshinge zo mu bwoko bwa angiography, byagurishijwe ku bikoresho bigera kuri 300 mu gihugu no mu mahanga, kandi byashimiwe n'abakiriya. Muri icyo gihe, LnkMed inatanga inshinge n'imiyoboro y'inyongera nk'ibikoresho byo gukoresha ku birango bikurikira: Medrad, Guerbet, Nemoto, nibindi, ndetse n'imiyoboro myiza y'umuvuduko, ibyuma bipima ferromagnetic n'ibindi bikoresho by'ubuvuzi. LnkMed yahoraga yizeye ko ubuziranenge ari inkingi y'iterambere, kandi yakomeje gukora cyane kugira ngo ihe abakiriya ibicuruzwa na serivisi byiza. Niba ushaka ibikoresho by'ishusho y'ubuvuzi, ikaze kugisha inama cyangwa kutwungurana ibitekerezo.
