Thyroid scintigraphy

Ngaphansi scintigraphy indlela ukuqonda uphethwe ukusebenza, okuyinto indlela yakhiwa esasikhipha emzimbeni izinto nge izakhiwo enemisebe. Umphumela isithombe, nangokunquma ngokuvamile izinga lemisebe ye sasikhipha.

izicubu Iskena yegilo senzelwe ukucacisa umsebenzi obusebenzayo amaseli ayo ngenombolo izinto radioactive engalibaleki izakhiwo.

Phakathi ukusebenza kwawo bumunca iodine, nezinye izinto ezidingekayo ukuze ekukhiqizweni kwama-hormone. Ijubane le nqubo akuyona njalo. Ngezinye izikhathi ezahlukene kungase ukwandisa noma ukunciphisa. Ngakho-ke, ukubaluleka ukusetshenziswa kwalezi izinto yisikali sokuthi isimo obusebenzayo indlala yegilo.

Ukuhlola of isimo sokusebenza oluphethwe isingeniso ku umzimba izinto ezikhethekile nomsebenzi radiology, okuyinto okwengeziwe sezithunyelwa zonke izicubu emzimbeni. Thyroid ukuncela inombolo ngokwanele ezinkulu izici eziningana ezinjengolwazi, enikeza le nkomba ngokobulili kuphela nezindlala salivary.

Ukuze siqonde ukuthi kusho ukuthini scintigraphy yegilo, kubalulekile ukwethula lokhu umzimba njengendlela lemifanekiso izinto. Badlula ngalé kwayo, futhi ngale ndlela buthelela egazini. Kukhona ubuhlobo obunjalo: ngokuhle obusebenzayo umthamo isihlungi zonke izinto, kuhlanganise radioisotopes, kangcono wasigcina ke. Nge passivity waligcina lomkhuba reverse (zonke izakhi awela kuyo akuhlungangwa, uhambe ngokuqondile egazini).

Scintigraphy we indlala yegilo iyisitho izindlela sokusebenza zokuxilonga ukunquma degree of saturation izicubu zawo nge isotopes enemisebe. Lesi sibalo likhomba umsebenzi ukusebenza emzimbeni.

Iskena kuyasiza ngokungaqondile ukunquma izici isakhiwo. Wabuka indlala yegilo kunqunywa ubukhulu bayo, isilinganiso izakhiwo esicishe esilinganayo entanyeni. Futhi, ngokuvumelana degree of ukumuncwa izinto radioactive kunqunywa isimo imfundo uhlamvu eqondile. Kodwa ucwaningo ezifana scintigraphy we indlala yegilo, ayikwazi kubhekwe elinembile, kuyinkomba. Lokhu kungenxa yokuthi ngesisekelo scintigraphy kuyinto ukucacisa sokusebenza we ndlala.

Lolu cwaningo njengoba scintigraphy kwezinso kudinga isicelo se-radioisotopes ezilandelayo: i-iodine-123, technetium-99m pertechnetate. Basuke iqondiswa ngemithambo yegazi, ezimweni ezingajwayelekile, ngomlomo. Ngemva isingeniso yabo esigulini ihamba ikhamera gamma, okuyinto othola kwemisebe izicubu indlala yegilo. Ibizwa nangokuthi isithwebuli wezokwelapha. Thyroid scintigraphy uphela ukunikeza imiphumela ezilotshwe ephepheni ezinemibala.

Kulo mfanekiso kubonakala engxenyeni engezansi ekhanda entanyeni nasesifubeni engenhla.

Ingemuva Wugqinsi sikhombisa ukugcwaliswa ngokwanele eliphezulu radioisotope izinto izindwangu. Nalokhu japan kuphothulwe umsebenzi omkhulu sokusebenza. Ephambi kwezinduna nezizinda ukukhanya ukhulume ukunciphisa umsebenzi indlala noma indawo yakhe. Ngo kwezokwelapha kuveta simo izikhungo density kukhona imigomo esetshenziswa: ashisayo nabandayo. Letimphawu evame ukubuzwa yibo bonke izinhlobo ucwaningo (phakathi inombolo yabo futhi isibindi scintigraphy). Ngo operation evamile, umzimba kumele ngokulinganayo yagcwala radioisotope, ezingxenyeni zalo akufanele abe opacities eqondile.

Ngakho stsintiografiya yegilo indlala kuyindlela ebalulekile zokuxilonga okuvumela ukuhlola isimo sokusebenza lomzimba ukubona izimo ezifana sokugembula njengoba i-hypothyroidism, i-hyperthyroidism.
