Kwabaningi bethu, imigomo yezokwelapha nezinqubo ziyimfihlakalo ngezikhombisa eziyisikhombisa. Kodwa ngezinye izikhathi akuyona neze into engafanele ukwazi ukuthi yiziphi izinkomba ezitholakalayo zokwenza i-MRT ye-pituitary ngokuphambene, indlela yokuyilungiselela ngayo, nokuthi yonke inqubo ihamba kanjani.
Umzimba we-Pituitary nokuphazanyiswa komsebenzi wakhe
I-pituitary gland ibhekiselwa ezingxenyeni eziphakathi ezifaka ama-hormone. Itholakala engxenyeni yobuchopho emgodleni we "Isikhwama saseTurkey" futhi uqukethe izingxenye ezimbili:
- ingxenye yangaphakathi (i-adenohypophysis);
- i-posterior (neurohypophysis).
Ubukhulu be-pituitary gland evamile akuyona enkulu. Ukuphakama kwalo ku-3-8 mm, ububanzi buyi-10-17 mm nesisindo asikho ngaphezu kwe-1 gram. Kodwa, naphezu kokusayizi okuthobekile, i-pituitary ifihla inani elikhulu lamahomoni abhekene nemisebenzi yokuzala yomzimba wabesilisa nabesifazane. Kunezinhlobo eziningi zezifo ezihambisana nokukhubazeka emsebenzini wakhe, ngokukhiqiza okwanele noma ngokweqile kwama-hormone e-pituitary. Izifo - ukukhuluphala ngokweqile, i-acromegaly, i-dwarfism, i-Itenko-Cushing syndrome, ukuphazamiseka kwengqondo, ukungabi nalutho - umphumela wokusebenza okungalungile kwe-gland pituitary.
Ukuphazamiseka okuhlukahlukene kwegciwane le-pituitary, i-hypothalamus nezitho eziseduze kungaholela emisebenzini engafanelekile. Njengomthetho, lezi zindlela ezinobungozi - i-adenomas. Ukusiza ekutholeni - i-pituitary adenoma - i-MRI iyinhloko ebalulekile. Njengoba izilonda zingase zingathinti yonke ingubo ye-pituitary, kodwa kuphela ingxenye yayo, ngakho-ke kubalulekile ukuthola isithombe ngokuchithwa okuncane kakhulu.
Ukwandisa izinga le-hormone ye- prolactin egazini kungahambisana nokubonakala kwe-microadenoma - uphawu oluvame kakhulu lwe-MRI ye-pituitary gland ngokuphambene. Uma ukwakheka kukhulu ngokwanele, ukwethulwa kwe-agent ehlukile kuzosiza ukuhlola kangcono isakhiwo saso kanye nemikhawulo.
Ukulungiselela nokuqhuba i-MRI ye-pituitary gland ngokuphambene
Naphezu kokuyinkimbinkimbi kwe-MRI ye-pituitary gland ngokuphambene, ukulungiswa kwesiguli kulula. Inqubo yenziwa ngesisu esingenalutho noma amahora angu-5-6 ngemva kokudla. Ngakho-ke, isikhathi esihle kakhulu se-MRI sisasa.
Inqubo ye-MRI ye-pituitary:
- Isidakamizwa sikhethwa ukuhlukana ngesisekelo se-gadolinium usawoti - iDotarem, Omniskan, Magnevist, gadovist. Ukuhlolwa kwe-scarification kwenziwa, isb. isilingo sokuthola umuthi kumuthi.
- Enye yezidakamizwa ezikhethiwe ijojowe noma i-injection ngomzuzu engaba ngu-30 ngaphambi kokuba inqubo iqale, noma yonke inqubo yokudonsa.
- Isiguli sigxilwe ku-apparatus ye-imagery magnetic resonance engqimba
isikhundla futhi kufanele ahlale ezolile futhi engahlali kahle ngesikhathi sonke sokuhlolwa. Isikhathi esincane se-MRI se-pituitary gland ngokuphambene cishe nehora elilodwa. - Kumele uqaphele ukuphikisana okunjalo njengokukhulelwa, ukutholakala kwezigulane ze-patient, izimila zensimbi, i-insulin pump. Futhi, susa zonke izinto zensimbi: ukubhoboza, okuyisisekelo, ubucwebe, amazinyo.
- Ezingxenyeni ezingokomqondo, ezihambisana nokunyakaza okuzimele, futhi lapho kukhona khona i- claustrophobia, i- MRI yenziwa ngokusetshenziswa kwezidakamizwa eziphuzayo.
