Chii icho ichi uye riini iro muviri wese scintigraphy inoitwa?

Zvemukati

• Kana yakazara muviri scintigraphy yaitwa
• How PCI inoitwa
• Kuchengeta pamberi pebvunzo

Wese-muviri scintigraphy kana yakazara-muviri kutsvagisa (PCI) bvunzo yemufananidzo yakakumbirwa nachiremba wako kuti aongorore nzvimbo yemarara, kufambira mberi kwezvirwere, uye metastasis. Kune izvi, zvinhu zvine radioactive, zvinonzi radiopharmaceuticals, zvinoshandiswa, senge iodine-131, octreotide kana gallium-67, zvinoenderana nechinangwa cheiyo scintigraphy, inoitiswa uye inosvitswa nenhengo, ichiburitsa radiation inoonekwa nemidziyo. Ziva icho icho radioactive iodine iri.

Mifananidzo yacho inowanikwa uchishandisa chishandiso, icho chinoteedzera muviri wese, mushure mezuva kana maviri ekutonga kwechinhu. Nekudaro, zvinokwanisika kuongorora kuti radiopharmaceutical inoparadzirwa sei mumuviri. Mhedzisiro yekuyedza inonzi yakajairika kana chinhu chikagovaniswa zvakaenzana mumuviri, uye chinoratidza chirwere kana kuwanda kwakanyanya kweradiopharmaceutical kunoonekwa munhengo kana dunhu remuviri.

Kana yakazara muviri scintigraphy yaitwa

Muviri wese scintigraphy inovavarira kuongorora iyo yekutanga saiti yebundu, iyo shanduko uye kuti kana kwete kana pane metastasis. Iyo radiopharmaceutical inoshandiswa inoenderana nekuti ndeipi system kana nhengo yaunoda kuongorora:

• PCI ine iodine-131: chinangwa chayo chikuru utachiona, kunyanya kune avo vakatobviswa utachiona;
• Gallium-67 PCI: inowanzoitwa kuongorora shanduko yema lymphomas, kutsvaga metastasis uye kuongorora hutachiona;
• PCI ine octreotide: zvinoitwa kuongorora matomu maitiro eiyo neuroendocrine mavambo, senge utachiona, pancreatic tumors uye pheochromocytoma. Ona maitiro ekuziva uye kubata pheochromocytoma.

Wese muviri scintigraphy inoitwa pasi pekutungamira kwekurapa uye haimiriri njodzi kumurwere, sezvo izvo zvinopihwa radioactive zvinhu zvakasununguka zvinobviswa mumuviri.

How PCI inoitwa

Iyo yakazara-muviri yekutsvaga inowanzoitwa mumatanho mana:

1. Kugadzirirwa kweiyo radioactive chinhu mudosi inofanirwa kupihwa;
2. Kutungamira kwedosi kune murwere, kungave nemuromo kana zvakananga mutsinga;
3. Kuwana mufananidzo, kuburikidza nekuverenga kunoitwa nemidziyo;
4. Kugadziriswa kwemifananidzo.

Scintigraphy yemuviri wese haiwanzoda kuti murwere atsanye, asi pane zvimwe zvinokurudzirwa kuteverwa zvichienderana nechinhu chinofanirwa kupihwa.

Muchiitiko che ayodini-131, zvinokurudzirwa kudzivirira chikafu chine hupfumi iodine, senge hove nemukaka, mukuwedzera kumisa kushandiswa kwemimwe mishonga, yakadai sevhitamini inowedzera uye mahormone etachiona usati waita bvunzo. Kana yakazara muviri scintigraphy isingaitwe, asi chete utachiona scintigraphy, iwe unofanirwa kutsanya kweanenge maawa maviri. Ona kuti thyroid scintigraphy inoitwa sei uye ndezvipi zvekudya zvine hupfumi muayodini izvo zvinofanirwa kudzivirirwa pakuongorora.

Kuongorora kunoitwa nemurwere akarara padumbu uye kunotora maminetsi makumi matatu kusvika makumi mana. MuPCI ine ayodhini-131 uye gallium-67, mifananidzo inotorwa 48h mushure mekutungamirwa kweiyo radiopharmaceutical, asi kana hutachiona hunofungidzirwa, PCI ine gallium-67 inofanira kutorwa pakati pa4 na6h mushure mekutarisirwa kwechinhu. MuPCI ine octreotide, iyo mifananidzo inotorwa kaviri, kamwe pamwe nemaawa matanhatu uye kamwe nemaawa makumi maviri nemana ekushandisa kwezvinhu.

Mushure mekuongororwa, munhu wacho anogona kudzokera kuzvinhu zvakajairwa uye anofanirwa kunwa mvura yakawanda kubatsira kubvisa radioactive chinhu nekukurumidza.

Kuchengeta pamberi pebvunzo

Usati waitwa kuongorora muviri wakazara, zvakakosha kuti munhu wacho audze chiremba kana aine chero rudzi rwezvirwere, kana vari kushandisa chero mishonga ine Bismuth, yakadai sePeptulan, semuenzaniso, iyo inoshandiswa gastritis, kana kana iwe uri nepamuviri kana uchiyamwisa, sezvo iyi mhando yekuongorora isingakurudzirwe, sezvo inogona kukanganisa mwana.

Zvimwe zvinokanganisa zvine chekuita nekutungamirwa kweiyo radiopharmaceuticals hazviwanzo, kunyanya nekuti madosi mashoma kwazvo anoshandiswa, asi zvinokanganisa kugadzikana, kuputika kweganda kana kuzvimba kunogona kuitika mudunhu raishandiswa chinhu ichi. Saka zvakakosha kuti chiremba azive mamiriro emurwere.
