I-Scantigraphy ayiyona enye yezindlela ezithandwa kakhulu, nakuba ngakolunye uhlangothi ibhekwa njengethuluzi lesimanje lokuxilonga, elisetshenziswa kumasu we-imaging. Isebenzisa ama-radioisotopes futhi ihlukaniswa ngobubanzi njengenkundla engaphansi yemithi yenuzi. Ikweleta ukuthandwa kwayo okukhulayo ngenxa yamathuluzi okuxilonga anembayo futhi angangeneleli kancane asetshenziswe phakathi nalokhu kuhlolwa. Ngenxa yabo, kungenzeka ukukala ikhono lezicubu nezitho zomuntu ngamunye ukuze ziqongelele izinhlanganisela ezithile noma izakhi zamakhemikhali. Ukuhlola okwenziwa ukuze kuhlonzwe izifo zesistimu yamathambo, amaphaphu, indlala yegilo, inhliziyo, nemigudu yenyongo. Ukukhulelwa kuyi-contraindication kulokhu kuhlolwa.
Iyini i-scintigraphy?
Ucwaningo lwe-renal isotope ukufaka esikhundleni kubizwa futhi i-renoscintigraphy or i-scintigraphy. Izibonelo zokuhlolwa okwenziwa kule ndawo i-renal scintigraphy, isotope renography, isotopic renoscintigraphy - indlela yokuthwebula ehlola ukwakheka nokusebenza kwezinso. Ukuqagela mayelana i-scintigraphy zihlobene nenkolelo yokuthi ezinye izicubu zinamandla okumunca amakhemikhali, okuholela, isibonelo, eqinisweni lokuthi i-iodine ngemva kokuphathwa izoqoqana ngezinga elikhulu ku-thyroid kunezinye izicubu. Ukuze wenze izakhi zamakhemikhali zibonakale, ama-isotopes anemisebe asetshenziswayo, okuthi ekubunjweni kwawo abe namanani ahlukene we-neutron anenkokhelo engathathi hlangothi ku-nucleus, ngakho-ke ayithinti izakhiwo zamakhemikhali zento. Ngezinye izikhathi ama-Radioisotopes anesilinganiso esingalungile sama-neutron kwamanye amabhlogo wokwakha ku-nucleus, okuwenza angagxili futhi abole. Lokhu kubola kubangela ukuba isici siguquke sibe esinye - sihambisana nokukhululwa kwemisebe. Umuthi wemvelo usebenzisa imisebe ye-gamma ngale njongo - okungukuthi, ukusebenzisa amaza kagesi.
Izifundo ze-isotopic zezinso - i-renoscintigraphy ne-scintigraphy
I-Renoscintigraphy kuhlanganisa nokunikeza imithamo efanelekile yama-isotopi anemisebe aqoqwe kuwo izinso, kuhlolwa ukunikezwa kwegazi ekuhluzweni kwe-glomerular, ukukhishwa kwe-tubular, nokuphuma komchamo. Ngezinye izikhathi, ucwaningo lusekelwa i-pharmacology ngokuphathwa ngokubambisana kwe-captopril. Ngemuva kokuthi ukuhlolwa sekuqediwe, kutholwa umbala ophrintiwe, oboniswayo izinso kanye nokucacisa ukuziphatha kwezikhombisi. Phansi i-renoscintigraphy udinga ukulungiselela ngokufanele. Into eyinhloko ukuthi kufanele ube esiswini esingenalutho. Ngesikhathi sokuhlolwa kuyadingeka ukugcina isikhundla esinganyakazi. Ngaphezu kwalokho, udokotela angase oda ukuhlolwa okwengeziwe okuhloswe ngalo, isb ukunqunywa kwe-serum creatinine. Uma izinso zakho zihluleka i-scintigraphy kungenziwa kuphela ngama-isotope tracers. Phakathi i-renografii isiguli silele esiswini, akudingekile ukukhumula izingubo zakhe, noma kunjalo, izinto zensimbi kufanele zisuswe ngalesi sikhathi, ukuba khona kwazo okuphazamisa isithombe se-scintigraphic. Ama-isotopes anemisebe afakwa emthanjeni, ngokuvamile angena emthanjeni wendololwane, ngesikhathi esifanele ngaphambi kokuba kuhlolwe i-scintigraphic. Kuye ngokuthi i-isotope isetshenziswa yiphi, ukuhlolwa ngokwako kuqala ihora elilodwa kuya kwamane kamuva. Isilinganiso ngokuvamile asidluli imizuzu eyi-10, futhi ukurekhodwa kwemiphumela cishe imizuzu engama-30. Uma ukuhlolwa kwe-pharmacological kwenziwa nge-furosemide, ilawulwa nge-intravenously futhi ibhekwe ukukhishwa komchamo ngezinso imizuzu embalwa. I-scintigraphy yezinso ngokuvamile kuthatha amaminithi ambalwa. Ngaphambi kokuhlolwa, udokotela kufanele aziswe ngesimo lapho kungeke kwenzeke khona ukuqoqa umchamo ukuze kuhlaziywe, mayelana nemithi ethathwe njengamanje, i-diathesis yokopha, ukukhulelwa. Ngesikhathi sokuhlolwa, kuyadingeka ukuqapha njalo isimo sesiguli futhi usabele uma kwenzeka ubuhlungu noma ukuphefumula. Ngemuva kokuhlolwa, akufanele ukhohlwe ukukhipha izinsalela ze-isotope emzimbeni. Bese ufinyelela izinhlobo ezahlukene zoketshezi - amanzi, itiye, amajusi. Ucwaningo lwe-renal isotope ingenziwa izikhathi eziningi, kungakhathaliseki ubudala besiguli. Abukho ubungozi bezinkinga.
