Ndlala scintigraphy

Phantsi indlela scintigraphy ukuqonda isifo functional, apho indlela inezi administering umzimba izinto ngempahla radioactive. Isiphumo umfanekiso, ngokumisela inqanaba radiation ekhutshwa.

Uvavanyo lengqula inyama yenzelwe ukugqiba umsebenzi esebenza ngayo iiseli zayo inani izinto radioactive emnandi izakhiwo.

Ngexesha osebenza oko ibizela ayodini, nezinye izinto eziyimfuneko ukuze imveliso hormone. Isantya yale nkqubo ayikho njalo. Maxa wambi ezahlukeneyo ngayo linokwanda okanye linciphe. Ngoko ke, ixabiso yokusebenzisa ezi zinto ngumlinganiselo le sokusebenza ngayo le ndlala lengqula.

Uvavanyo lwe sokusebenza olugcinwe yi-kokukhutshelwa eziphilayo kwezinto ezizodwa kunye umsebenzi zeradiyoloji, ezo ngakumbi athunyelwa kuzo zonke izihlunu zomzimba. Thyroid ukufunxa inani elikhulu ngokwaneleyo na izinto ezinjalo, ukunika esi salathisi ngesondo kuphela kunye namadlala amathe.

Ukuze uqonde ukuba yintoni na scintigraphy lengqula, kuyimfuneko ukwazisa le omzimba lokucoca izinto. Baya kucanda kulo ilizwe, kwaye ngale ndlela yande egazini. Kukho ubudlelwane loo: namandla functional isihluzi elungileyo zonke izinto, kuquka radioisotopes, ngcono kugcinwa kuyo. Nge passivity waligcina isenzeko umva (zonke izinto kuwela kulo nto ecociweyo, uye ngqo kwi egazini).

Scintigraphy le ndlala lengqula kukho iindlela ezisebenzayo zokuxilonga ukugqiba isidanga se Ukwanda kwithishyu yalo izinto ezineeathom ezilinganayo eqhumayo. Eli nani lunika umsebenzi ukusebenza komzimba.

Uvavanyo lunceda ukuba ukujonga ngokungangqalanga iimpawu zesi sakhiwo. Yakhiwe le ingaba lengqula ixhomekeke ubungakanani bayo, umlinganiselo izakhiwo yinyosi wesikolo bebekwe ngokwahlukeneyo omnye entanyeni. Kwakhona, ngokutsho neqondo ukufakwa kwezinto radioactive kumiselwa ngurhulumente onjani focal imfundo. Kodwa isifundo efana scintigraphy le nobubovu lengqula, asikwazi kuqwalaselwa echanileyo, oko kubonisa. Oku kungenxa yokuba isiseko scintigraphy kukuqinisekisa sokusebenza ngayo le ndlala.

Olu phando njengoko scintigraphy sezintso ifuna ukusetyenziswa radioisotopes zilandelayo: ayodini-123, technetium-99m pertechnetate. Bona zilawulwa yegazi, kwiimeko ezinqabileyo, ngomlomo. Emva kokuba ukuqaliswa yabo isigulane ihambisa camera gamma, apho ufumana imitha evela nezihlunu le ndlala lengqula. Libizwa ngokuba isithwebuli zonyango. Thyroid scintigraphy iphela ukunika iziphumo ezithi zibhalwe kwiphepha elinombala.

Kulo mfanekiso kubonakala inxalenye esezantsi entloko entanyeni kunye nesifuba eliphezulu.

Imvelaphi Density ubonisa Ukwanda sezingeni eliphezulu izinto radioisotope amalaphu. Nale japan kuphothulwe umsebenzi omkhulu olusebenzayo. Phambi iimvelaphi ukukhanya kuthetha ukunciphisa umsebenzi esinobubovu okanye site yakhe. Xa yezonyango ukuchaza ukuba amaziko lexinene iikota babesebenzisa: ashushu nabandayo. Ezi mpawu zixhaphakile kuzo zonke iintlobo zophando (phakathi Inani labo kunye zesibindi scintigraphy). Ukusebenza eziqhelekileyo, umzimba kufuneka ngokulungelelana ezaliswe radioisotope, awo angabi opacities focal.

Ngaloo stsintiografiya thyroid ndlala kukho indlela diagnostic ebalulekileyo ivumela ukuhlola imeko yomsebenzi lomzimba ukubona iimeko zophendlo lwezifo ezifana hypothyroidism, hyperthyroidism.
