Scintigraphy si imodzi mwa njira zodziwika bwino, ngakhale kumbali inayo imadziwika ngati chida chamakono chodziwira matenda, chomwe chimagwiritsidwa ntchito mu njira yojambula zithunzi. Amagwiritsa ntchito ma radioisotopes ndipo amagawidwa ndi kukula ngati gawo laling'ono lamankhwala a nyukiliya. Zili ndi mbiri yomwe ikukula chifukwa cha zida zowunikira zomwe zimagwiritsidwa ntchito pakuwunikaku. Chifukwa cha iwo, ndizotheka kuyeza kuthekera kwa minyewa ndi ziwalo kuti zidziunjikirana ndi mankhwala kapena zinthu zina. Ndi mayeso omwe amachitidwa kuti azindikire matenda a chigoba, mapapo, chithokomiro, mtima, ndi ndulu. Mimba ndi contraindication kuti mayesero.
Kodi scintigraphy ndi chiyani?
Kuphunzira kwa isotopu ya aimpso kulowetsa kumatchedwanso renoscintigraphy or scintigraphy. Zitsanzo za mayesero omwe amachitidwa m'derali ndi impso scintigraphy, isotope renography, isotopic renoscintigraphy - njira yojambula yomwe imayang'ana mapangidwe ndi ntchito ya impso. Zongoganizira za scintigraphy zimagwirizana ndi chikhulupiliro chakuti minyewa ina imatha kuyamwa mankhwala, zomwe zimabweretsa, mwachitsanzo, kuti ayodini pambuyo pa makonzedwe adzaunjikana kwambiri m'chithokomiro kuposa minofu ina. Pofuna kuti zinthu za mankhwala ziwonekere, ma isotopi a radioactive amagwiritsidwa ntchito, omwe muzolemba zawo amakhala ndi ma neutroni osiyanasiyana omwe ali ndi ndalama zopanda ndale mu nucleus, kotero samakhudza mankhwala a chinthucho. Ma radioisotopes nthawi zina amakhala ndi chiŵerengero cholakwika cha ma neutroni ku midadada ina yomangira pakatikati, kuwapangitsa kukhala osakhazikika komanso owola. Kuwola kumeneku kumapangitsa kuti chinthucho chisinthe kukhala china - limodzi ndi kutuluka kwa ma radiation. Mankhwala achilengedwe amagwiritsa ntchito ma radiation a gamma pachifukwa ichi - ndiko kuti, pogwiritsa ntchito mafunde a electromagnetic.
Maphunziro a isotopic a impso - renoscintigraphy ndi scintigraphy
Renoscintigraphy imakhala ndi kupereka milingo yoyenera ya isotopu ya radioactive yomwe imasonkhanitsidwa impso, chifukwa chomwe magazi amalowa mu kusefera kwa glomerular, kutuluka kwa tubular, ndi kutuluka kwa mkodzo kumayesedwa. Nthawi zina, kafukufukuyu amathandizidwa ndi pharmacology pothandizirana ndi captopril. Kuyesako kukatsirizidwa, chosindikizira chamtundu chimapezedwa, chikuwonetsa impso ndi kufotokoza mchitidwe wa zolozera. Pansi renoscintigraphy muyenera kukonzekera moyenerera. Chinthu chachikulu ndi chakuti muyenera kukhala pamimba yopanda kanthu. Pa kafukufuku m`pofunika kusunga akadali udindo. Komanso, dokotala akhoza kuyitanitsa zina mayesero umalimbana mwachitsanzo mtima wa seramu creatinine ndende. Ngati impso zanu zikulephera scintigraphy zitha kuchitika ndi zolozera za isotopu. Nthawi renografii wodwalayo agona pamimba pake, sikoyenera kuvula zovala zake, komabe, zinthu zachitsulo ziyenera kuchotsedwa panthawiyi, kukhalapo kwake komwe kumasokoneza chithunzi cha scintigraphic. Ma radioactive isotopes amaperekedwa kudzera m'mitsempha, nthawi zambiri mumtsempha wa m'chigono fossa, panthawi yoyenera miyeso ya scintigraphic isanapangidwe. Kutengera ndi isotopu yomwe imagwiritsidwa ntchito, kuyesa komweko kumayamba maola amodzi kapena anayi pambuyo pake. Kuyeza nthawi zambiri sikudutsa mphindi 10, ndipo kujambula zotsatira pafupifupi mphindi 30. Ngati mayeso a pharmacological amachitidwa ndi furosemide, amaperekedwa kudzera m'mitsempha ndikuwona excretion ya mkodzo ndi impso kwa mphindi zingapo. Impso scintigraphy nthawi zambiri zimatenga mphindi zingapo. Asanayambe kuunika, dokotala ayenera kudziwitsidwa za mmene kudzakhala kosatheka kusonkhanitsa mkodzo kusanthula, za panopa anamwa mankhwala, magazi diathesis, mimba. Pa kufufuza, m`pofunika nthawi zonse kuwunika mmene wodwalayo alili ndi kuchita pa chochitika cha ululu kapena kupuma movutikira. Pambuyo pa mayeso, musaiwale kuchotsa zotsalira za isotope m'thupi. Kenako mumafikira mitundu yosiyanasiyana yamadzimadzi - madzi, tiyi, timadziti. Kuphunzira kwa isotopu ya aimpso akhoza kuchitidwa nthawi zambiri, mosasamala kanthu za msinkhu wa wodwalayo. Palibe chiopsezo cha zovuta.
