Kwa ambiri a ife, mawu azachipatala ndi ndondomeko ndi chinsinsi ndi zisindikizo zisanu ndi ziwiri. Koma nthawi zina sizingatheke kudziwa zomwe zikupezeka pochita MRT yokhala ndi zosiyana, momwe mungakonzekere, ndi momwe ntchito yonseyo ikuyendera.
Thupi lopuma komanso kusokoneza ntchito yake
Mtundu wa pituitary umatchulidwa kumadera akuluakulu omwe amatulutsa mahomoni. Ndili pamunsi pa ubongo m'kati mwa "Chisilamu cha Turkey" ndipo chimakhala ndi magawo awiri:
- gawo lina (adenohypophysis);
- posachedwa (neurohypophysis).
Kukula kwa chidziwitso chodziwika bwino si chachikulu. Kutalika kwake ndi 3-8 mm, m'lifupi ndi 10-17 mm ndipo kulemera sikuposa 1 gramu. Koma, ngakhale kuti sizing'onozing'ono kukula, pituitary imabweretsa mahomoni ambiri omwe amayang'anira ntchito yobereka ya thupi la amuna ndi akazi. Pali nthenda zambiri za matenda omwe amagwiridwa ndi kuwonongeka kwa ntchito yake, ndi kuchuluka kwa mahomoni osakwanira kapena ochuluka. Matenda - kunenepa kwambiri, acromegaly, dwarfism, matenda a Itenko-Cushing, matenda ena a m'maganizo, kusabereka - zotsatira za kusagwiritsidwa ntchito kosayenera kwa chifuwa cha pituitary.
Kusiyana kosiyanasiyana kwa nthenda ya pituitary, hypothalamus ndi ziwalo zoyandikana zingayambitse ntchito. Monga lamulo, izi ndizoonongeka - adenomas. Kuthandizira kupeza - pituitary adenoma - MRI ndi udindo waukulu. Popeza zilonda zingasokoneze mtundu wonse wa chifuwa, koma mbali yake yokha, ndikofunikira kuti mupeze chithunzi ndi molondola kwambiri.
Kuwonjezeka kwa mavitamini a prolactin m'magazi kungaphatikizepo maonekedwe a microadenoma - chisonyezero chofala kwambiri cha MRI cha mankhwala a pituitary posiyana. Ngati mapangidwewa ndi okwanira, kuyambika kwa wothandizira osiyana kumathandiza kuti muyambe bwino kuyang'anitsitsa kayendedwe kake ndi makondomu.
Kukonzekera ndi kuyendetsa MRI ya gland pituitary mosiyana
Ngakhale zovuta za MRI za mankhwala a pituitary ndi zosiyana, kukonzekera kwa wodwala ndi kosavuta. Ndondomekoyi imachitidwa m'mimba yopanda kanthu kapena maola 5-6 mutatha kudya. Choncho, nthawi yabwino ya MRI ndikum'mawa.
Ndondomeko ya MRI ya pituitary:
- Mankhwala amasankhidwa kuti asinthe pa maziko a salt gadolinium - Dotarem, Omniskan, Magnevist, gadovist. Kuyesedwa koyesa kumapangidwa, i.e. chiyeso choletsera mankhwala.
- Mmodzi wa mankhwala osankhidwa amaloledwa kamodzi kamodzi mwa intravenously ndi jekeseni kwa mphindi 30 asanayambe ndondomekoyi, kapena nthawi yonseyo.
- Wodwala amaikidwa m'zipangizo za maginito ojambula m'maganizo
udindo ndipo ayenera kukhala wodekha komanso wosasunthika panthawi yonseyi. Nthawi yokwanira ya MRI ya chigoba cha pituitary ndi kusiyana kwa ora limodzi. - Muyenera kumvetsera zotsutsana ndi izi monga mimba, kupezeka kwa odwala, opaleshoni ya chitsulo, insulini mpope. Komanso, chotsani zinthu zonse zitsulo: kuboola, chakudya, zodzikongoletsera, mano.
- Kuvutika maganizo, motsatizana ndi kayendetsedwe kake, komanso pamaso pa claustrophobia, MRI imagwiritsidwa ntchito pogwiritsa ntchito mankhwala osokoneza bongo.
