Scintigraphy tsis yog ib txoj hauv kev nrov tshaj plaws, txawm hais tias ntawm qhov tod tes nws tau pom tias yog cov cuab yeej kuaj mob niaj hnub, uas yog siv rau hauv cov txheej txheem imaging. Nws siv cov xov tooj cua isotopes thiab raug cais los ntawm kev ua haujlwm raws li thaj chaw ntawm cov tshuaj nuclear. Nws tshuav nws qhov muaj koob meej zuj zus mus rau qhov tseeb thiab tsis tshua muaj kev cuam tshuam cov cuab yeej kuaj mob siv thaum lub sijhawm kuaj xyuas no. Ua tsaug rau lawv, nws muaj peev xwm ntsuas lub peev xwm ntawm cov ntaub so ntswg thiab cov khoom nruab nrog cev kom sib sau cov ntsiab lus tshwj xeeb lossis tshuaj lom neeg. Nws yog ib qho kev sim uas tau ua los kuaj xyuas cov kab mob ntawm lub cev pob txha, lub ntsws, cov thyroid, lub plawv, thiab cov kua tsib. Cev xeeb tub yog contraindication rau qhov kev kuaj no.
Dab tsi yog scintigraphy?
Kev tshawb nrhiav lub raum isotope kev hloov pauv kuj hu ua renoscintigraphy or scintigraphy. Piv txwv ntawm kev ntsuam xyuas hauv cheeb tsam no yog lub raum scintigraphy, isotope renography, isotopic renoscintigraphy - ib txoj hauv kev kuaj xyuas cov qauv thiab kev ua haujlwm ntawm lub raum. Kev xav txog scintigraphy cuam tshuam nrog kev ntseeg tias qee cov ntaub so ntswg muaj peev xwm nqus tau cov tshuaj, uas ua rau, piv txwv li, qhov tseeb tias iodine tom qab kev tswj hwm yuav ua rau ntau dua hauv cov thyroid ntau dua li lwm cov ntaub so ntswg. Txhawm rau ua kom pom cov tshuaj lom neeg, cov isotopes siv hluav taws xob, uas nyob rau hauv lawv cov muaj pes tsawg leeg muaj ntau cov neutrons nrog cov nqi nruab nrab hauv cov nucleus, yog li lawv tsis cuam tshuam rau cov khoom siv tshuaj lom neeg ntawm lub caij. Radioisotopes qee zaum muaj qhov tsis ncaj ncees lawm ntawm neutrons rau lwm lub tsev thaiv hauv lub nucleus, ua rau lawv tsis ruaj khov thiab lwj. Qhov kev lwj no ua rau lub caij hloov mus rau lwm qhov - nrog rau kev tso tawm hluav taws xob. Cov tshuaj ntuj siv gamma hluav taws xob rau lub hom phiaj no - uas yog, siv hluav taws xob nthwv dej.
Lub raum isotopic kev tshawb fawb - renoscintigraphy thiab scintigraphy
Renoscintigraphy muaj nyob rau hauv kev tswj cov koob tshuaj uas tsim nyog ntawm cov isotopes radioactive sau nyob rau hauv raum, ua tsaug uas cov ntshav muab rau lub glomerular filtration, tubular secretion, thiab zis tso zis raug soj ntsuam. Qee zaum, txoj kev tshawb fawb no tau txais kev txhawb nqa los ntawm kws tshuaj los ntawm kev tswj hwm ntawm captopril. Tom qab qhov kev xeem tiav lawm, tau txais ib daim ntawv luam tawm xim, qhia raum thiab qhia txog tus cwj pwm ntawm tus taw tes. nqes renoscintigraphy koj yuav tsum tau npaj raws li. Qhov tseem ceeb tshaj plaws yog tias koj yuav tsum nyob hauv plab khoob. Thaum lub sij hawm ntsuam xyuas nws yog ib qho tsim nyog yuav tsum khaws ib qho chaw tseem ceeb. Tsis tas li ntawd, tus kws kho mob tuaj yeem xaj cov kev sim ntxiv txhawm rau txhawm rau txiav txim siab ntawm cov ntshav creatinine concentration. Yog tias koj lub raum tsis ua haujlwm scintigraphy tsuas tuaj yeem ua nrog isotope tracers. Thaum renografii tus neeg mob pw ntawm nws lub plab, nws tsis tas yuav tshem nws cov khaub ncaws, txawm li cas los xij, cov khoom hlau yuav tsum tau muab tshem tawm tam sim no, muaj qhov cuam tshuam nrog cov duab scintigraphic. Radioactive isotopes yog muab tso rau hauv cov hlab ntsha, feem ntau mus rau hauv cov hlab ntsha hauv lub luj tshib fossa, ntawm lub sijhawm tsim nyog ua ntej kev ntsuas scintigraphic. Nyob ntawm seb qhov twg isotope siv, qhov ntsuas nws tus kheej pib ib mus rau plaub teev tom qab. Kev ntsuas feem ntau tsis tshaj 10 feeb, thiab cov ntaub ntawv teev tseg txog 30 feeb. Yog tias kev sim tshuaj kho mob tau ua nrog furosemide, nws raug muab tso rau hauv cov hlab ntsha thiab pom tshem tawm cov zis los ntawm lub raum rau ob peb feeb. Lub raum scintigraphy feem ntau yuav siv li ob peb feeb. Ua ntej kev ntsuam xyuas, tus kws kho mob yuav tsum tau qhia txog qhov xwm txheej uas nws yuav tsis tuaj yeem sau cov zis rau kev tshuaj xyuas, txog cov tshuaj tam sim no, los ntshav diathesis, cev xeeb tub. Thaum lub sij hawm kuaj, nws yog ib qho tsim nyog yuav tsum tau saib xyuas tus neeg mob tas li thiab hnov mob thaum muaj mob lossis ua tsis taus pa. Tom qab kev sim, koj yuav tsum tsis txhob hnov qab yaug cov seem ntawm isotope los ntawm lub cev. Tom qab ntawd koj ncav cuag ntau hom kua - dej, tshuaj yej, kua txiv hmab txiv ntoo. Kev tshawb nrhiav lub raum isotope tuaj yeem ua tau ntau zaus, tsis hais tus neeg mob lub hnub nyoog li cas. Tsis muaj kev pheej hmoo ntawm cov teeb meem.
