Yenzelwe ntoni kwaye yenziwe nini yonke into ngomzimba wonke?

Umxholo

• Xa umzimba opheleleyo we-scintigraphy wenziwe
• Kwenziwa njani i-PCI
• Khathalela phambi koviwo

I-scintigraphy yomzimba wonke okanye uphando lomzimba wonke (i-PCI) luvavanyo lomfanekiso oluceliwe ngugqirha wakho ukuphanda indawo yethumba, ukuqhubela phambili kwesifo, kunye ne-metastasis. Ukwenza oku, kusetyenziswa izinto ezinemitha ye-radio, ebizwa ngokuba yi-radiopharmaceuticals, njenge-iodine-131, i-octreotide okanye i-gallium-67, ngokuxhomekeke kwinjongo ye-scintigraphy, elawulwa kwaye ifunxwe ngamalungu, ikhupha imitha efunyanwa sisixhobo. Yazi ukuba yeyiphi iodine eqhumayo.

Imifanekiso ifunyenwe kusetyenziswa isixhobo, esilanda umzimba uphela, emva kosuku okanye ezimbini zolawulo lwento leyo. Ke, kunokwenzeka ukuba uqinisekise ukuba i-radiopharmaceutical isasazwa njani emzimbeni. Iziphumo zovavanyo kuthiwa ziqhelekile xa into isasazwa ngokulinganayo emzimbeni, kwaye ibonisa isifo xa uxinzelelo oluphezulu lwe-radiopharmaceutical lubonwa kwilungu okanye kummandla womzimba.

Xa umzimba opheleleyo we-scintigraphy wenziwe

Umzimba wonke we-scintigraphy ujolise ekuphandeni indawo ephambili yethumba, uguquko kunye nokuba akukho metastasis na. I-radiopharmaceutical esetyenzisiweyo ixhomekeke kwinkqubo okanye ilungu ofuna ukulivavanya:

• I-PCI ene-iodine-131: Eyona njongo yayo iphambili yidlala lengqula, ngakumbi kwabo sele besuswe idlala lengqula;
• IGallium-67 PCI: kudla ngokwenziwa ukukhangela indaleko ye-lymphomas, ukukhangela i-metastasis kunye nokuphanda usulelo;
• I-PCI ene-octreotide: kwenziwa ukuvavanya iinkqubo zethumba ezinemvelaphi ye-neuroendocrine, enje nge-thyroid, i-pancreatic tumors kunye ne-pheochromocytoma. Jonga indlela yokuchonga kunye nokunyanga i-pheochromocytoma.

Umzimba wonke we-scintigraphy wenziwa phantsi kolawulo lwezonyango kwaye awubonakalisi mngcipheko kwisigulana, kuba izinto ezenziwa ngemitha ye-radioactive zikhutshwa ngokwendalo emzimbeni.

Kwenziwa njani i-PCI

Uphando olupheleleyo lomzimba lwenziwa ngokwamanqanaba amane:

1. Ukulungiswa kwezinto ezinemitha yeathom idosi eza kulawulwa;
2. Ulawulo lwedosi kwisigulana, nokuba kungomlomo okanye ngqo emthanjeni;
3. Ukufumana umfanekiso, ngokufunda okwenziwe sisixhobo;
4. Ukulungiswa kwemifanekiso.

I-Scintigraphy yomzimba uphela ayidingi ukuba isiguli sikhawuleze, kodwa kukho iingcebiso ekufuneka zilandelwe ngokuxhomekeke kwinto ekufuneka yenziwe.

Kwimeko ye-iodine-131, kuyacetyiswa ukuba kuthintelwe ukutya okune-iodine eninzi, njengentlanzi kunye nobisi, ukongeza ekumiseni ukusetyenziswa kwamayeza athile, anje ngeevithamin supplements kunye nehomoni yedlala ngaphambi kokwenza uvavanyo. Ukuba i-scintigraphy yomzimba epheleleyo ayenziwanga, kodwa kuphela yi-scintigraphy ye-thyroid, kuya kufuneka ukhawuleze ubuncinci iiyure ezi-2. Jonga ukuba yenziwe njani i-scintigraphy ye-thyroid kunye nokutya okunotyebileyo kwi-iodine ekufuneka ithintelwe kuvavanyo.

Uviwo lwenziwa ngesigulana esilele ngesisu kwaye sihlala malunga nemizuzu engama-30 ukuya kwengama-40. Kwi-PCI ene-iodine-131 kunye ne-gallium-67, imifanekiso ithathwa ngama-48h emva kolawulo lwe-radiopharmaceutical, kodwa ukuba kukrokrelwa ukosuleleka, i-PCI ene-gallium-67 kufuneka ithathwe phakathi kwe-4 kunye ne-6h emva kolawulo lwento leyo. Kwi-PCI ene-octreotide, imifanekiso ithathwa kabini, kube kanye malunga neeyure ezingama-6 kwaye kube kanye ngeeyure ezingama-24 zolawulo lweziyobisi.

Emva koviwo, umntu lowo angabuyela kwimisebenzi yesiqhelo kwaye kufuneka asele amanzi amaninzi ukunceda ukuphelisa into enemitha ye-radio ngokukhawuleza.

Khathalela phambi koviwo

Phambi kokuba kuhlolwe umzimba wonke, kubalulekile ukuba umntu axelele ugqirha ukuba ngaba unalo naluphi na uhlobo lokungezwani komzimba, ukuba usebenzisa naliphi na iyeza eliqukethe iBismuth, njengePeptulan, umzekelo, esetyenziselwa isisu, okanye ukuba ukhulelwe okanye uncelisa, njengoko olu hlobo loviwo lungacetyiswa, njengoko lunokuchaphazela umntwana.

Iziphumo ebezingalindelekanga ezinxulumene nolawulo lwe-radiopharmaceuticals zinqabile, ubuncinci kuba kusetyenziswa iidosi ezisezantsi kakhulu, kodwa ukusabela okungafunekiyo komzimba, irhashalala okanye ukudumba kunokwenzeka kummandla apho kulawulwa khona le nto. Ke kubalulekile ukuba ugqirha ayazi imeko yesigulana.
