Kodi ndi chiyani ndipo ndi liti pamene thupi lonse limachita masewera olimbitsa thupi?

Zamkati

• Pamene scintigraphy yathunthu yachitika
• Momwe PCI yachitidwira
• Kusamalira mayeso asanafike

Kujambula thupi lonse kapena kufufuza thupi lonse (PCI) ndi kuyesedwa kwazithunzi komwe dokotala wanu akufunsani kuti mufufuze malo omwe ali ndi chotupa, kukula kwa matenda, ndi metastasis. Pachifukwa ichi, zinthu zama radioact, zotchedwa radiopharmaceuticals, zimagwiritsidwa ntchito, monga ayodini-131, octreotide kapena gallium-67, kutengera cholinga cha scintigraphy, yomwe imayendetsedwa ndikulowetsedwa ndi ziwalo, kutulutsa ma radiation omwe amapezeka ndi zida. Dziwani kuti ayodini ya radioactive ndiyotani.

Zithunzizi zimapezeka pogwiritsa ntchito chida, chomwe chimatsata thupi lonse, patatha tsiku limodzi kapena awiri oyang'anira zinthuzo. Chifukwa chake, ndizotheka kutsimikizira momwe radiopharmaceutical imagawidwira mthupi. Zotsatira zoyeserera akuti sizachilendo pamene mankhwalawo amagawidwa mofananamo mthupi, ndipo amawonetsa matenda pomwe kuchuluka kwa radiopharmaceutical kumadziwika m'chiwalo kapena gawo la thupi.

Pamene scintigraphy yathunthu yachitika

Scintigraphy yathunthu yathunthu imafufuza malo oyamba a chotupa, chisinthiko komanso ngati pali metastasis kapena ayi. Ma radiopharmaceutical omwe amagwiritsidwa ntchito amatengera mtundu wanji kapena chiwalo chomwe mukufuna kuwunika:

• PCI yokhala ndi ayodini-131: cholinga chake chachikulu ndi chithokomiro, makamaka kwa iwo omwe adachotsedwa kale chithokomiro;
• Gallium-67 PCI: nthawi zambiri amachitidwa kuti ayang'ane kusintha kwa ma lymphomas, kusaka metastasis ndikufufuza matenda;
• PCI yokhala ndi octreotide: zimachitika kuti ziwunikire njira zotupa zoyambira neuroendocrine, monga chithokomiro, zotupa za kapamba ndi pheochromocytoma. Onani momwe mungadziwire ndi kuchiza pheochromocytoma.

Scintigraphy yathunthu imachitidwa motsogozedwa ndi azachipatala ndipo siyimayimira chiopsezo kwa wodwalayo, chifukwa zinthu zomwe zimayatsidwa ndi radioactive zimachotsedwa mthupi.

Momwe PCI yachitidwira

Kusaka kwathupi lathunthu kumachitika m'njira zinayi:

1. Kukonzekera mankhwala a radioactive muyezo woti uperekedwe;
2. Kuperekera kwa wodwalayo, kaya pakamwa kapena mwachindunji mumtsempha;
3. Kupeza chithunzichi, powerenga zomwe zidapangidwa ndi zida;
4. Kusintha kwazithunzi.

Zolemba pamanja za thupi lonse sizimafuna kuti wodwala azisala kudya, koma pali malingaliro ena omwe angatsatidwe kutengera ndi chinthu chomwe akuyenera kupatsidwa.

Pankhani ya ayodini-131, tikulimbikitsidwa kupewa zakudya zokhala ndi ayodini wambiri, monga nsomba ndi mkaka, kuwonjezera pakuletsa kugwiritsa ntchito mankhwala ena, monga mavitamini owonjezera mavitamini ndi mahomoni a chithokomiro musanayese mayeso. Ngati scintigraphy yathunthu isadachitike, koma chithokomiro chokha, muyenera kusala kudya kwa maola osachepera 2. Onani momwe scintigraphy ya chithokomiro imachitikira komanso zakudya zomwe zili ndi ayodini wambiri zomwe ziyenera kupewedwa poyesa.

Kuyesaku kumachitika wodwalayo atagona m'mimba mwake ndipo amakhala pafupifupi mphindi 30 mpaka 40. Mu PCI yokhala ndi ayodini-131 ndi gallium-67, zithunzi zimatengedwa 48h pambuyo pa kayendedwe ka radiopharmaceutical, koma ngati matenda akukayikiridwa, PCI yokhala ndi gallium-67 iyenera kutengedwa pakati pa 4 ndi 6h pambuyo poyendetsa mankhwalawo. Mu PCI yokhala ndi octreotide, zithunzizo zimatengedwa kawiri, kamodzi ndi pafupifupi maola 6 ndipo kamodzi ndi maola 24 oyang'anira zinthu.

Pambuyo pofufuzidwa, munthuyo amatha kubwerera kuzinthu zachilendo ndipo ayenera kumwa madzi ambiri kuti athandize kuthana ndi vuto la radioactive mwachangu.

Kusamalira mayeso asanafike

Asanapimidwe thupi lonse, ndikofunikira kuti munthuyo auze adotolo ngati ali ndi vuto lililonse, ngati akugwiritsa ntchito mankhwala aliwonse omwe ali ndi Bismuth, monga Peptulan, omwe amagwiritsidwa ntchito ngati gastritis, kapena ngati muli ndi pakati kapena mukuyamwitsa, popeza kuyerekezera kwamtunduwu sikuvomerezeka, chifukwa kumakhudza mwanayo.

Zotsatira zoyipa zokhudzana ndi kuyang'anira ma radiopharmaceuticals ndizosowa, makamaka chifukwa mankhwala otsika kwambiri amagwiritsidwa ntchito, koma zovuta, zotupa pakhungu kapena kutupa kumatha kuchitika mdera lomwe mankhwalawo amaperekedwa. Chifukwa chake ndikofunikira kuti dokotala adziwe momwe wodwalayo alili.
