Scintigraphy haisi imwe yenzira dzakakurumbira, kunyange kune rumwe rutivi inonzwisiswa sechinhu chemazuva ano chekuongorora, chinoshandiswa mumifananidzo yekufungidzira. Inoshandisa radioisotopes uye inorongedzerwa nechiyero sechikamu chechikamu chemishonga yenyukireya. Iyo ine chikwereti chayo kukura kukurumbira kune chaiyo uye ishoma invasive diagnostic maturusi anoshandiswa panguva iyi bvunzo. Kutenda kwavari, zvinokwanisika kuyera kugona kwemunhu mumwe nemumwe uye nhengo kuunganidza chaiwo makomisheni kana makemikari zvinhu. Muedzo unoitwa kuona zvirwere zveskeletal system, mapapu, thyroid, moyo, uye bile ducts. Kubata pamuviri kunopesana nemuedzo uyu.
Chii chinonzi scintigraphy?
Renal isotope kudzidza kutsiva kunonzi zvakare renoscintigraphy or scintigraphy. Mienzaniso yemiedzo yakaitwa munzvimbo iyi ndeye itsvo scintigraphy, isotope renography, isotopic renoscintigraphy - nzira yekufungidzira inoongorora chimiro uye basa reitsvo. Kufungidzira nezve scintigraphy inoenderana nekutenda kuti mamwe matishu ane kugona kutora makemikari, izvo zvinoguma, semuenzaniso, mukuti iodine mushure mekutonga ichaungana kusvika pamwero mukuru muhuro pane mune mamwe matushu. Kuti aite kuti zvinhu zvemakemikari zvionekwe, radioactive isotopes inoshandiswa, iyo mukuumbwa kwayo ine huwandu hwakasiyana hwemanyutroni ane neatural charge mumukati, saka haakanganisa makemikari echinhu. MaRadioisotopes dzimwe nguva ane reshiyo isiriyo yemanyutroni kune mamwe mabhuroko ekuvaka ari mukati memoyo, zvichiita kuti asagadzikane uye aore. Kuora uku kunoita kuti chinhu chishanduke kuita chimwe - chichiperekedzwa nekuburitswa kwemwaranzi. Mushonga wechisikigo unoshandisa gamma radiation nekuda kweichi chinangwa - ndiko kuti, kushandisa mafungu emagetsi.
Isotopic zvidzidzo zveitsvo - renoscintigraphy uye scintigraphy
Renoscintigraphy inosanganisira kupa madosi akakodzera emaradioactive isotopes akaunganidzwa mukati kidneys, nekuda kwekuti ropa rinopiwa kune glomerular filtration, tubular secretion, uye kubuda kweweti kunoongororwa. Dzimwe nguva, chidzidzo chinotsigirwa ne pharmacology nekubatana-kutonga kwe captopril. Mushure mekunge bvunzo yapera, kudhindwa kwemavara kunowanikwa, kuratidza kidneys uye kutsanangura maitiro ezvinongedzera. Pasi renoscintigraphy unofanira kugadzirira maererano. Chinhu chikuru ndechekuti iwe unofanirwa kunge uri padumbu risina chinhu. Panguva yekuongorora zvakakosha kuchengetedza nzvimbo yakanyarara. Uye zvakare, chiremba anogona kuraira kumwe kuongororwa kwakanangana nekuita semuenzaniso kutsunga kweserum creatinine concentration. Kana itsvo dzako dziri kupera simba scintigraphy inogona kuitwa chete ne isotope tracers. Panguva renografii murwere anorara padumbu, hazvidiwi kubvisa zvipfeko zvake, zvisinei, zvinhu zvesimbi zvinofanira kubviswa panguva ino, kuvapo kweiyo kunokanganisa mufananidzo we scintigraphic. Radioactive isotopes inoiswa mutsinga, kazhinji mutsinga iri mugokora fossa, panguva yakakodzera kusati kwaitwa zviyero zve scintigraphic. Zvichienderana neiyo isotopu inoshandiswa, bvunzo pachayo inotanga imwe kusvika maawa mana gare gare. Chiyero chacho kazhinji hachipfuuri maminitsi gumi, uye kurekodha kwemigumisiro inenge maminitsi makumi matatu. Kana kuongororwa kwemishonga kuchiitwa nefurosemide, inotungamirirwa nemukati uye inocherechedza kubuda weti neitsvo kwemaminiti akati wandei. Kidney scintigraphy kazhinji inotora maminitsi gumi nemaviri. Pamberi pekuongororwa, chiremba anofanira kuziviswa pamusoro pemamiriro ezvinhu apo hazvizobviri kuunganidza weti kuti iongororwe, pamusoro pemishonga ikozvino inotorwa, kubuda ropa diathesis, pamuviri. Munguva yekuongorora, zvinodikanwa kugara uchitarisa mamiriro emurwere uye kuita mumamiriro ekurwadziwa kana kupera kwekufema. Mushure mebvunzo, haufanirwe kukanganwa kuburitsa masara eisotope kubva mumuviri. Ipapo iwe unosvika pamhando dzakasiyana dzezvinwiwa - mvura, tii, muto. Renal isotope kudzidza inogona kuitwa kakawanda, pasinei nezera remurwere. Hapana ngozi yematambudziko.
