MIBG scintiscan

MIBG scintiscan bụ ụdị nyocha onyonyo. Ọ na - eji ihe na - eme ihe onyonyo (akpọrọ tracer). Igwe nyocha na-achọta ma ọ bụ na-egosi ịdị adị nke pheochromocytoma na neuroblastoma. Ndị a bụ ụdị etuto ahụ na-emetụta anụ ahụ akwara.

A na-agbanye redioisotope (MIBG, iodine-131-meta-iodobenzylguanidine, ma ọ bụ iodine-123-meta-iodobenzylguanidine) n'ime eriri. Ngwakọta a na-arapara na mkpụrụ ndụ akpụ.

Later ga-enyocha nyocha ahụ ma emechaa ụbọchị ahụ ma ọ bụ n’echi ya. Maka akụkụ nke ule a, ị dinara na tebụl n'okpuru ogwe aka nyocha. A na-enyocha ime afọ gị. Nwere ike ịlaghachi maka nyocha ugboro ugboro 1 ruo ụbọchị 3. Nyocha ọ bụla na-ewe 1 gaa 2 awa.

Tupu ma ọ bụ n'oge ule ahụ, enwere ike inye gị ngwakọta ayodiin. Nke a na - egbochi gland gị ịmịnye nnukwu redioisotope.

Ikwesiri ịbịanye aka na nnabata nkwenye. A ga-agwa gị ka ị eyi uwe akwa ụlọ ọgwụ ma ọ bụ akwa nwere akwa. Kwesịrị iwepu ọla ma ọ bụ ihe ọla tupu nyocha ọ bụla. Ọtụtụ ọgwụ ọjọọ na-egbochi ule ahụ. Jụọ onye na-ahụ maka ahụike gị otu n'ime ọgwụ ndị ị na-a regularụ oge niile ị ga-achọ ịkwụsị ịnara tupu ule ahụ.

Ga-enwe mmetụta agịga dị nkọ mgbe etinyere ihe ahụ. Tebụl nwere ike oyi ma ọ bụ sie ike. Ghaghagharịrị ịgha ụgha n'oge nyocha.

Emere ule a iji nyere aka chọpụta pheochromocytoma. A na-eme ya mgbe nyocha CT abdominal ma ọ bụ nyocha MRI dị n'ime afọ adịghị enye azịza doro anya. A na-ejikwa ya iji nyere aka chọpụta neuroblastoma ma enwere ike iji ya maka ọrịa cancer carcinoid.

Enweghị ihe ịrịba ama nke etuto ahụ.

Nsonaazụ na-adịghị mma nwere ike igosi:

• Pheochromocytoma
• Otutu endocrine neoplasia (MEN) II
• Ọrịa carcinoid
• Neuroblastoma

Enwere ụfọdụ ikpughe na radieshon site na redioisotope. Igwe redio a sitere na redioisotope a dị elu karịa ọtụtụ ndị ọzọ. Ikwesiri ịkpachapụ anya maka ụbọchị ole na ole mgbe ule ahụ gachara. Onye na-eweta gị ga - agwa gị ihe ị ga - eme.

Tupu ma ọ bụ n'oge ule ahụ, enwere ike ịnye gị ọgwụ ayodiin. Nke a ga - eme ka gland gị ghara ịmịnye iodine oke. Ọtụtụ mgbe ndị mmadụ na-ewere potassium iodide maka ụbọchị 1 tupu ụbọchị isii gachara. Nke a na-egbochi thyroid ị takingụ MIBG.

E kwesịghị ime ule a na ụmụ nwanyị dị ime. Igwe radieshon ahụ nwere ike ibutere nwa ebu n'afọ nsogbu.
