Ukuskena kwe-thyroid

Iskena se-thyroid sisebenzisa i-iodine tracer yokuhlola ukwakheka kunye nokusebenza kwe-thyroid gland. Olu vavanyo luhlala lusenziwa kunye novavanyo lwe-iodine.

Uvavanyo lwenziwa ngale ndlela:

• Unikwa ipilisi enesixa esincinci se-iodine eqhumayo. Emva kokuyiginya, linda njengoko iodine iqokelela kwi-thyroid yakho.
• Iskena sokuqala sihlala senziwa iiyure ezi-4 ukuya kwezi-6 emva kokuba uthathe ipilisi ye-iodine. Olunye uvavanyo luhlala lwenziwa kwiiyure ezingama-24 kamva. Ngexesha lokuskena, ulele ngomqolo kwitafile eshukumayo. Intamo nesifuba sakho zibekwe phantsi kweskena. Kuya kufuneka uxoke ukuze iskena sifumane umfanekiso ocacileyo.

Iskena sibona indawo kunye nobungakanani bemitha ekhutshwe zizinto ezinemitha yeathom. Ikhompyuter ibonisa imifanekiso ye-thyroid gland. Ezinye izikena zisebenzisa into ebizwa ngokuba yi-technetium endaweni ye-iodine ene-radioactive.

Landela imiyalelo malunga nokungatyi ngaphambi kovavanyo. Unokuxelelwa ukuba ungatyi emva kobusuku ngaphambi kokuskena kwakho kusasa.

Xelela umboneleli wakho wezempilo ukuba uthatha nantoni na equlathe iodine kuba inokuchaphazela iziphumo zakho zovavanyo. Oku kubandakanya amayeza athile, kubandakanya iziyobisi ze-thyroid kunye namayeza entliziyo. Izixhasi ezifana ne-kelp nazo ziqulethe iodine.

Xelela umboneleli wakho ukuba unayo:

• Urhudo (lunokunciphisa ukufunxeka kwe-iodine ene-radioactive)
• Ngaba iskena se-CT samva nje besebenzisa umahluko we-iodine-based based (kwiiveki ezi-2 ezidlulileyo)
• Incinci kakhulu okanye iodine eninzi ekudleni kwakho

Susa izacholo, amazinyo emboleko okanye ezinye izinyithi kuba zinokuphazamisa umfanekiso.

Abanye abantu bakufumanisa kungonwabanga ukuhlala uzolile ngexesha lovavanyo.

Olu vavanyo lwenziwe:

• Vavanya amaqhuqhuva e-thyroid okanye i-goiter
• Fumana unobangela wegland engasebenziyo
• Jonga umhlaza wedlala lengqula (kunqabile, kuba ezinye iimvavanyo zichanekile koku)

Iziphumo zovavanyo eziqhelekileyo ziya kubonisa ukuba idlala lengqula libonakala lilingana nobukhulu, imilo, kunye nendawo efanelekileyo. Umbala ongwevu kumfanekiso wekhompyuter ngaphandle kweendawo ezimnyama okanye ezikhanyayo.

Idlala lengqula elandisiweyo okanye elityhalelweyo kwelinye icala linokuba luphawu lwethumba.

Amaqhuqhuva afunxa iodine engaphezulu okanye engaphantsi kwaye oku kuya kubangela ukuba zibonakale zimnyama okanye zikhaphukhaphu xa kuskenwa. Iqhuqhuva lihlala likhaphukhaphu xa lingakhange lithathe iodine (edla ngokubizwa ngokuba yi''band 'nodule). Ukuba inxenye ye-thyroid ibonakala ilula, ingaba yingxaki ye-thyroid. Amaqhuqhuva amnyama ngakumbi athathe i-iodine engaphezulu (edla ngokubizwa ngokuba yi-'shushu 'nodule). Bangakwazi ukugqithisa kwaye banokuba yimbangela ye-thyroid engasebenzi.

Ikhompyuter iya kubonisa ipesenti ye-iodine eqokelelwe kwi-thyroid gland (i-radioiodine). Ukuba i-gland yakho iqokelela iodine eninzi, inokubangelwa yi-thyroid engasebenzi. Ukuba i-gland yakho iqokelela iodine encinci, inokubangelwa kukudumba okanye omnye umonakalo kwidlala lengqula.

Yonke imitha ineziphumo ebezingalindelekanga ezinokwenzeka. Inani le-radioactivity lincinci kakhulu, kwaye akubangakho ziphumo zecala zibhaliweyo.

Abasetyhini abakhulelweyo okanye abancancisayo akufuneki benze olu vavanyo.

Thetha nomboneleli wakho ukuba unenkxalabo malunga nolu vavanyo.

Iodine eqhumayo ishiya umzimba wakho kumchamo wakho. Akunyanzelekanga ukuba uthathe amanyathelo okhuseleko, njengokugungxula kabini emva kokuchama, kangangeeyure ezingama-24 ukuya kweziyi-48 emva kovavanyo kuba ithamo le-iodine ene-radioactive liphantsi kakhulu. Buza umboneleli wakho okanye iradiology / iqela lamayeza enyukliya elenza scan malunga nokuthatha amanyathelo okhuseleko.
