Thyroid scintigraphy

Under scintigraphy nzira kunzwisisa dzichipfekeka nechirwere, iyo nzira unotora yachengetwa nemuviri zvinhu pamwe radioactive ehupfumi. Zvinoguma chifananidzo, kubudikidza Pakusarudza pachiyero chaibwinya mwaranzi.

Kushanda pakuvheneka thyroid rinenge zvichiitirwa kuona dzichipfekeka basa masero ayo vakaverengwa radioactive zvinhu inobaya mwoyo ehupfumi.

Panguva huchishanda nayo absorbs ayodhini, zvimwe zvinhu zvakafanira kuti pagadzirwe mahormone. Nokumhanya izvi hakusi kugara. Panguva dzakasiyana-siyana zvingava kuwedzera kana kutapudza. Naizvozvo, ukoshi kudyiwa izvi zvinhu ari nechiyero dzichipfekeka mamiriro thyroid shwanu.

Assessment ose dzichipfekeka mamiriro iri dzaidzidziswa pakusuma kupinda muviri zvinokosha zvinhu pamwe radiological basa, izvo mberi kukamurirwa nyama dzose muviri. Thyroid Sechipanji munhu zvakakwana vakawanda vakadaro okunze, achipa chakarurama ichi chete pabonde uye mate mumasero.

Kuti tinzwisise zvinodzidziswa thyroid scintigraphy, zvakakodzera kusuma muviri ichi chive Sefa kuti zvinhu. Ivo napo, uye nenzira iyi uchingounganidza mu muropa. Pane ukama hwakadaro: nezvakanaka dzichipfekeka vachikwanisa Sefa zvinhu zvose, kusanganisira radioisotopes, nani zvichachengetwawo mariri. With passivity vake vakachengeta neizvi chakajairika (zvinhu zvose achawira mariri asina yakasvinwa, uende zvakananga kupinda muropa).

Scintigraphy of thyroid shwanu kushanda chirwere nzira yokuziva ukuru saturation pakati zvinyama dzayo radioactive isotopes. Nhamba iyi zvinopa rairatidza dzichipfekeka basa muviri.

Kushanda pakuvheneka zvinobatsira zvisina kunanga kuona zvinhu chacho. The contours zviri thyroid shwanu vagara vandifungira saizi yayo, nhamba kupfuura kunyatsotevera munzvimbo dzokuzororera dzaiva zvivako zviri mumutsipa. Uyewo, maererano mwero Absorção de Água pamusoro radioactive zvinhu vagara vandifungira mamiriro dzidzo zvatichiri hunhu. Asi kudzidza kwakadaro sezvo scintigraphy pamusoro thyroid shwanu, haagoni kunzi yakarurama, zviri INDICATIVE. Izvi imhaka yokuti hwaro scintigraphy ndiko kuona dzichipfekeka mamiriro shwanu.

Kudzidza uku sezvo renal scintigraphy zvinoda kushanda zvinotevera radioisotopes: ayodhini-123, technetium-99m pertechnetate. Vari kutarisirwa nomutsinga, muna zvisingawanzoitiki nguva achishandisa muromo. Pashure pokukurukurirana yavo murwere inobaya wegamma kamera, izvo anogamuchira nemwaranzi kubva munyama pamusoro thyroid shwanu. It anonziwo zvokurapa scanner. Thyroid scintigraphy inoguma kupa mhinduro izvo zvakanyorwa pamusoro chitsvuku papepa.

Mumufananidzo kunooneka yepazasi chikamu musoro pamwe nemutsipa uye yokumusoro muchipfuva.

Background Density unoratidza zvakakwana yakakwirira saturation kuti radioisotope zvinhu micheka. With ichi mugumisiro zvinonzi akagumisa yakakwirira dzichipfekeka basa. In pamberi chiedza siyana nezvazvo kuderedza kushanda shwanu kana wake nzvimbo. Mune okurapa kureva nzvimbo arambe achirema anoshandiswa mazwi Hot uye kuchitonhora. zviratidzo izvi ndezvemamiriro mhando dzose kutsvakurudza (pakati nhamba uye chiropa scintigraphy). Chaiye mashandiro, muviri anofanira zvakaenzana yakazara radioisotope, zvikamu zvayo haafaniri kuva musimboti wokuzadzika opacities.

Saka stsintiografiya thyroid shwanu kunokosha chirwere nzira iyo anobvumira kuongorora dzichipfekeka mamiriro ezvinhu muviri uye kuona zvinhu zvakadai pathological sezvo hypothyroidism, hyperthyroidism.
