Kwabaninzi kuthi, imigaqo yezokwelapha kunye neenkqubo ziyimfihlelo ngeempawu ezixhenxe. Kodwa ngamanye amaxesha akukho konke ukungazi ukuba zeziphi izibonakaliso ezikhoyo zokwenza i-MRT ye-pituitary ngokuhlukileyo, indlela yokuyilungiselela ngayo, kunye nendlela yonke inkqubo ehamba ngayo.
Umzimba wokuzimela kunye nokuphazamiseka komsebenzi wakhe
I-pituitary gland ibhekiselwa kwiingqungquthela eziphambili ezikhupha ama-hormone. Itholakala kwisiseko sobuchopho kwisigxina se "Isibhedlele saseTurkey" kwaye sinamalungu amabini:
- inxalenye yangaphambili (adenohypophysis);
- i-posterior (neurohypophysis).
Ubungakanani bentambo evamile ye-pituitary ayikho enkulu. Ukuphakama kwayo ngu-3-8 mm, ububanzi buyi-10-17 mm kwaye ubunzima abuyi ngaphezu kwe-1 gram. Kodwa, nangona ubukhulu becala bukhulu, i-pituitary ifihla inani elikhulu lee-hormone ezijongene nemisebenzi yokuzala yomzimba wabantu nabasetyhini. Kukho isibalo esikhulu sezifo ezinxulumene nokukhubazeka emsebenzini wakhe, ngokuvelisa okwaneleyo okanye okugqithisileyo ama-hormone e-pituitary. Izifo - ukukhuluphala, u-acromegaly, ukutshatyalaliswa kwemithi, i-Itenko-Cushing syndrome, ezinye iingxaki zengqondo, ukungabikho kwempilo-ngenxa yesenzo esingalunganga se-pituitary gland.
Iziphazamiso ezahlukahlukeneyo ze-pituitary gland, i-hypothalamus kunye nezitho eziseduze zingakhokelela kwimisebenzi engenakusebenza. Njengomthetho, ezi ziyizo ezinobungozi - i-adenomas. Ukunceda ekuhloleni - i-pituitary adenoma-MRI iyona nxaxheba ephambili. Ekubeni izilonda zingenakuchaphazela yonke i-pituitary gland, kodwa yodwa inxalenye yayo, ke kubalulekile ukufumana umfanekiso ngokuchaneka okukhulu.
Ukwandisa izinga le-hormone yeprolactin egazini lihamba kunye nokubonakala kwe-microadenoma - uphawu oluqhelekileyo lwe-MRI ye-pituitary gland ngokuchaseneyo. Ukuba ukubunjwa kubanzi ngokwaneleyo, ukuqaliswa kwe-ejenti eyahlukileyo kuya kunceda ukuphonononga ngcono isakhiwo sayo kunye nemida.
Ukulungiselela nokuqhuba i-MRI yesiganeko se-pituitary ngokwahlukileyo
Nangona kunzima kwe-MRI ye-pituitary gland ngokuchaseneyo, ukulungiswa kwesigulane kulula. Inkqubo eyenziwa kwisisu esingenanto okanye amahora ama-5-6 emva kokutya. Ngoko ke, ixesha elihle le-MRI likusasa.
Inkqubo ye-MRI ye-pituitary:
- Ikhefu likhethwa ukuba lichasane ngesiseko se-gadolinium salts - iDotarem, Omniskan, Magnevist, gadovist. Uvavanyo lwe-scarification lwenziwe, i. ukuvavanya ukuxilisa kwiyeza.
- Enye yezilwanyana ezikhethiweyo zijojowe ngeyodwa nge-injection nge-injection malunga nemizuzu engama-30 ngaphambi kokuba inkqubo iqalise, okanye yonke inqubo iqhube.
- Isigulane sifakwa kwisixhobo somfanekiso we-magnetic resonance kwi-horizontal
sikhundla kwaye kufuneka sihlale sizolile kwaye sisisigxina ngexesha loviwo lonke. Ixesha elimalunga ne-MRI ye-pituitary gland ngokuhlukileyo malunga neyure eli-1. - Kufuneka ubeke ingqalelo kwiingqinisiso ezifana nokukhulelwa, ubukho bezithuthuthu zezigulane, ukufakelwa kwesinyithi, ukupompa kwe-insulin. Kwakhona, susa zonke izinto zetsimbi: ukubhoboza, iziqwenga, ubucwebe, amazinyo.
- Kwiintlupheko zengqondo, ezihamba kunye nokunyanzelisa ukungabikho kokuzibandakanya, kunye ne- claustrophobia, i- MRI yenziwa ngokusetyenziswa kwezidakamizwa ezithobileyo.
