Iskena sendlala yegilo

Iskena se-thyroid sisebenzisa i-radioactive iodine tracer ukuhlola ukwakheka nokusebenza kwendlala yegilo. Lokhu kuhlolwa kuvame ukwenziwa kanye nokuhlolwa kokutholwa kwe-iodine enemisebe.

Ukuhlolwa kwenziwa ngale ndlela:

• Unikezwa iphilisi eliqukethe inani elincane le-iodine enemisebe. Ngemuva kokuyigwinya, ulinda njengoba iodine iqoqa ku-thyroid yakho.
• Ukuskena kokuqala kuvame ukwenziwa emva kwamahora ama-4 kuya kwayisithupha ngemuva kokuthatha iphilisi le-iodine. Okunye ukuskena kuvame ukwenziwa ngemuva kwamahora angama-24. Ngesikhathi sokuskena, ulala ngomhlane etafuleni elihambayo. Intamo nesifuba sakho kubekwe ngaphansi kwesithwebuli. Kufanele ulale unganyakazi ukuze isithwebuli sithole isithombe esicacile.

Isithwebuli sithola indawo nobukhulu bemisebe ekhishwe yimpahla enemisebe. Ikhompyutha ikhombisa izithombe zendlala yegilo. Amanye amaskena asebenzisa into ebizwa nge-technetium esikhundleni se-iodine enemisebe.

Landela imiyalelo mayelana nokungadli ngaphambi kokuhlolwa. Ungatshelwa ukuthi ungadli ngemuva kwamabili ngaphambi kokuskena kwakho ngakusasa ekuseni.

Tshela umhlinzeki wakho wezokunakekelwa kwempilo uma uthatha noma yini equkethe iodine ngoba ingathinta imiphumela yakho yokuhlolwa. Lokhu kufaka phakathi eminye imithi, kufaka phakathi izidakamizwa ze-thyroid nemithi yenhliziyo. Izithasiselo ezinjenge-kelp nazo ziqukethe iodine.

Tshela nomhlinzeki wakho uma une:

• Uhudo (lunganciphisa ukumuncwa kwe-iodine enemisebe)
• Ngabe i-CT yakamuva iskena isebenzisa ukungafani okususelwa ku-iodine (emavikini amabili edlule)
• Iodine encane kakhulu noma eningi ekudleni kwakho

Susa ubucwebe, amazinyo okufakelwa, noma ezinye izinsimbi ngoba zingaphazamisa isithombe.

Abanye abantu bakuthola kungakhululekile ukuhlala bethule ngesikhathi sokuhlolwa.

Lokhu kuhlolwa kwenziwa ku:

• Linganisa amaqhuqhuva e-thyroid noma i-goiter
• Thola imbangela yegciwane le-thyroid elingaphezu kwamandla
• Bheka umdlavuza wegilozi (kuyaqabukela, ngoba okunye ukuhlolwa kunembe ngalokhu)

Imiphumela yokuhlolwa ejwayelekile izokhombisa ukuthi indlala yegilo ibonakala isayizi, ukuma, nokuthi isendaweni efanele. Umbala ompunga ngisho nasekhompyutheni ngaphandle kwezindawo ezimnyama noma ezikhanyayo.

Indlala yegilo ekhulisiwe noma ecindezelwe yaya ohlangothini olulodwa ingaba uphawu lwesimila.

Amaqhuqhuva amunca iodine engaphezulu noma engaphansi futhi lokhu kuzowenza abukeke emnyama noma alula kakhulu kuskena. I-nodule ivame ukuba lula uma ingakayithathi i-iodine (evame ukubizwa ngokuthi yi-'cold' nodule). Uma ingxenye yegilo ibonakala ilula, kungaba yinkinga yegilo. Amaqhuqhuva amnyama kakhulu athathe i-iodine eyengeziwe (evame ukubizwa ngokuthi yi-'hot' nodule). Zingasebenza ngokweqile futhi kungaba yimbangela yegilo elisebenza ngokweqile.

Ikhompyutha izophinda ikhombise iphesenti le-iodine eliqoqwe ku-thyroid gland yakho (i-radioiodine uptake). Uma i-gland yakho iqoqa iodine eningi kakhulu, kungenzeka ukuthi kungenxa ye-thyroid engasebenzi. Uma indlala yakho iqoqa iodine encane kakhulu, kungenzeka kungenxa yokuvuvukala noma omunye umonakalo wegilo.

Yonke imisebe inemiphumela engemihle engaba khona. Inani le-radioactivity lincane kakhulu, futhi akubanga khona miphumela emibi ebhaliwe.

Abesifazane abakhulelwe noma abancelisayo akufanele babe nalokhu kuhlolwa.

Khuluma nomhlinzeki wakho uma unenkinga ngalokhu kuhlolwa.

Iodine enemisebe ishiya umzimba wakho ngomchamo wakho. Akudingeki ukuthi uthathe izinyathelo ezithile zokuqapha, njengokugubha kabili ngemuva kokuchama, amahora angama-24 kuye kwangama-48 ngemuva kokuhlolwa ngoba umthamo we-iodine enemisebe uphansi kakhulu. Buza umhlinzeki wakho noma ithimba lemithi ye-radiology / yenuzi elenza ukuskena mayelana nokuthatha izinyathelo zokuphepha.
