Radioactive iodine 131, dav siv hauv tshuaj, yog ib qho isotope ntawm cov tshuaj lom neeg. Nws muaj peev xwm ua kom lwj tsis pub dhau 8 hnub, tsim cov khoom ntawm cov beta electron ceev, quantum ntawm gamma hluav taws xob thiab xenon.
Radioactive iodine yog siv los kho ntau yam kab mob. Kev kho mob nrog cov tshuaj no tso cai rau kom ua tiav kev rov zoo ntawm ntau dua 80 feem pua ntawm cov neeg mob uas muaj metastases hauv lub ntsws los ntawm cov thyroid cancer. Nyob rau tib lub sijhawm, hauv 90 feem pua ntawm cov neeg mob, tsis muaj kev rov tshwm sim hauv 10 xyoo.
Thaum lub sijhawm kho, gelatin capsules uas muaj cov tshuaj iodine yog siv los ntawm qhov ncauj. Tsis tas li ntawd, cov tshuaj aqueous ntawm cov isotope yog siv, uas tsis muaj organoleptic zog (sab, xim, tsw). Lub caij, accumulating nyob rau hauv lub hlwb ntawm cov thyroid caj pas, exposes tag nrho lub caj pas rau gamma thiab beta hluav taws xob. Qhov no tso cai rau koj los rhuav tshem cov qog hlwb nyob hauv lub cev thiab dhau mus. Kev kho mob radioiodine yuav tsum tau mus pw hauv tsev kho mob hauv lub chaw tshwj xeeb.
Lub hom phiaj tseem ceeb ntawm kev kho mob yog kev tawm tsam ntawm kev ua sithyroid caj pas, tshwj xeeb tshaj yog nyob rau hauv cov chaw ua hauj lwm overworked. Tom qab ib chav kawm ntawm kev noj cov isotope, nws accumulates precisely nyob rau hauv cov cheeb tsam uas pib txoj kev loj hlob ntawm thyrotoxicosis. Nyob rau tib lub sijhawm, hluav taws xob ua rau nws tuaj yeem rhuav tshem cov foci.
Cov thyroid muaj nuj nqi rov qab los rau hauv cov neeg mob tom qab siv hluav taws xob.
Radioactive iodine therapy rau diffuse thiab nodular toxic goiters yog ua los ntawm kev siv tshuaj tsawg. Nyob rau tib lub sijhawm, kev ua haujlwm ntawm cov thyroid caj pas yog khaws cia rau hauv tus neeg mob thaum lub sijhawm kho. Kev ua tau zoo ntawm kev kho mob goiter lom yog nyob ntawm txoj kev uas tus neeg tau npaj rau kev kho mob thiab cov koob tshuaj iodine tau sau tseg.
Txoj kev siv feem ntau hauv cov chaw kho mob, uas tso cai rau kev suav cov koob tshuaj ntawm cov isotope raws li cov kev xeem sib sau, tsis muaj txiaj ntsig zoo, vim nws ua rau cov tshuaj noj tshuaj tsis tsim nyog. Raws li qhov tshwm sim, ntau tus neeg mob ntsib kev rov qab los ntawm thyrotoxicosis tom qab kho.
Cov txiaj ntsig zoo ntawm kev kho yog tau los ntawm cov txheej txheem uas muaj nyob rau hauv kev siv cov dej num ruaj khov isotope.
Radioactive iodine yog kev kho mob zoo tshaj plaws rau cov thyroid cancer (follicular thiab papillary).
Kev siv hluav taws xob kho mob yog qhov muaj ntau. Nws raug sau tseg tsis yog rau cov neeg mob qog noj ntshav xwb. Cov txheej txheem no yog txoj hauv kev tseem ceeb rau kev kho mob thyrotoxicosis, uas yog tshwm sim los ntawm kev ua kom muaj zog ntawm benign nodes. Qhov feem ntau isotopetso cai rau koj los kho cov thyroid kab mob yam tsis muaj teeb meem, txij li cov koob tshuaj ntawm cov tshuaj tau muab rau tib neeg lub cev me me thiab raug hluav taws xob tsis ua rau muaj kev phiv los yog teeb meem. Qhov tsuas yog contraindication rau kev siv xov tooj cua iodine yog cev xeeb tub.
Cov neeg mob uas tau txais kev kho isotope tuaj yeem txhim kho hypothyroidism dhau sijhawm. Qhov kev sib txawv no yooj yim tswj tau los ntawm kev noj cov thyroid hormones.
