Kedu ihe onyonyo ahụike?
Nleba anya ahụike nuklia (nke a na-akpọkwa radionuclide scanning) bụ ngwá ọrụ nyocha dị irè n'ihi na ọ na-egosi na ọ bụghị naanị anatomi (nhazi) nke akụkụ ahụ ma ọ bụ akụkụ ahụ, kamakwa ọrụ nke akụkụ ahụ.Ihe mgbakwunye "ozi arụ ọrụ" a na-enye ohere ọgwụ nuklia iji chọpụta ọrịa ụfọdụ na ọnọdụ ahụike dị iche iche ngwa ngwa karịa nyocha ahụike ahụike ndị ọzọ nke na-enye ozi gbasara akụkụ ahụ ma ọ bụ akụkụ ahụ.Ọgwụ nuklia nwere ike ịba uru na nyocha mmalite, ọgwụgwọ na mgbochi nke ọtụtụ ọnọdụ ahụike ma na-aga n'ihu na-eto dị ka ngwa ọrụ ahụike siri ike.
Maka ọtụtụ ụlọ ọrụ nlekọta ahụike na-enye njikwa onyogho nyocha ahụike bụ akụkụ nke ndụ ha kwa ụbọchị maka usoro redio izugbe (ya bụ, CT, MR, X-ray, PET, SPECT, wdg).Otú ọ dị, ndị ọkachamara na ụlọ ọrụ ndị a, site na ndị dọkịta, ndị na-ahụ maka nkà na ụzụ, na ndị nchịkwa, na ndị ọrụ PACS/IT, na-enwekwa mmetụta mgbu nke enweghị ngwọta PACS kwesịrị ekwesị maka usoro dị iche iche.Usoro ndị PACS kacha arụ ọrụ bụ usoro onyonyo ihe omimi nke nuklia, gụnyere PET-CT, SPECT-CT, cardiology nuklia na ọgwụ nuklia izugbe.
Ọ bụ ezie na onyonyo molekụla nuklia dị ntakịrị n'ịtụle ọnụ ọgụgụ ule a na-eme kwa afọ, a pụghị ileda mkpa ya anya, ma n'ụlọ ọgwụ ma n'ụzọ ego.PET-CT ka egosipụtara na ọ bụ usoro ezi uche ma a bịa n'ịchọpụta ọrịa kansa.Ọrịa obi nuklia abụrụla ụdị nhọrọ maka ọrịa obi na-adịghị emebi emebi.Ọgwụ ọgwụ nuklia n'ozuzu na-enye ọtụtụ ngwa onyonyo na-arụ ọrụ nke enweghị usoro ọzọ nwere ike dakọtara.N'ụzọ ego, PET-CT na ọrịa obi nuklia ka so na usoro akwụghachi ụgwọ kachasị elu na onyonyo nyocha.
