IMIBG iscisciscan

I-MIBG scintiscan luhlobo lovavanyo lokucinga. Isebenzisa into enemitha yeathom (ebizwa ngokuba yitracer). Iskena sifumana okanye siqinisekisa ubukho be-pheochromocytoma kunye neuroblastoma. Ezi ziindidi zamathumba ezichaphazela izicwili zemithambo-luvo.

I-radioisotope (i-MIBG, iodine-131-meta-iodobenzylguanidine, okanye iodine-123-meta-iodobenzylguanidine) ifakwe kwisitya. Eli qela linamathela kwiiseli ezithile zethumba.

Uya kuba nokuskena kamva ngalo mhla okanye ngosuku olulandelayo. Kule nxalenye yovavanyo, ulala phezu kwetafile phantsi kwengalo yeskena. Isisu sakho siskeniwe. Kuya kufuneka ubuye ukuze uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphinde uphumelele. Iskena ngasinye sithatha iiyure ezi-1 ukuya kwezi-2.

Ngaphambi okanye ngexesha lovavanyo, unokunikwa umxube we-iodine. Oku kuthintela i-thyroid gland ekufumaneni i-radioisotope.

Uya kudinga ukusayina ifom yemvume unolwazi. Uya kucelwa ukuba unxibe ilokhwe yasesibhedlele okanye iimpahla ezikhululekileyo. Uya kudinga ukususa ubucwebe okanye izinto zesinyithi ngaphambi kokuskena. Amachiza amaninzi aphazamisa uvavanyo. Buza umboneleli wakho wezempilo ukuba ngawaphi amayeza akho aqhelekileyo onokuwadinga ukuyeka ukuwathatha ngaphambi kovavanyo.

Uya kuziva unenaliti ebukhali xa isixhobo sitofiwe. Itafile inokubanda okanye inzima. Kufuneka uxoke ulele ngexesha lokuskena.

Olu vavanyo lwenziwa ukunceda ukufumanisa i-pheochromocytoma. Kuyenziwa xa isisu se-CT esiswini okanye isisu se-MRI esiswini singaniki mpendulo. Isetyenziselwa ukufumanisa isifo se-neuroblastoma kwaye inokusetyenziselwa amathumba e-carcinoid.

Akukho zimpawu zethumba.

Iziphumo ezingaqhelekanga zingabonisa:

• Pheochromocytoma
• Uninzi lwe-endocrine neoplasia (MEN) II
• Isisu seCarcinoid
• Neuroblastoma

Kukho ukubonakaliswa kwemitha kwi-radioisotope. Imitha evela kule radioisotope iphezulu kunezinye ezininzi. Kuya kufuneka uthathe amanyathelo okhuseleko kwiintsuku ezimbalwa emva kovavanyo. Umboneleli wakho uya kukuxelela ukuba yeyiphi inyathelo oza kulithatha.

Ngaphambi okanye ngexesha lovavanyo, unokunikwa isisombululo se-iodine. Oku kuya kugcina i-thyroid gland ingafumani iodine eninzi. Ngokwesiqhelo abantu bathatha i-potassium iodide kusuku olu-1 ngaphambi kunye neentsuku ezi-6 emva koko. Oku kuthintela idlala lengqula ukuba lingathathi i-MIBG.

Olu vavanyo ALUFUNI ukwenziwa kubafazi abakhulelweyo. Imitha inokuba yingozi kusana olungekazalwa.
