MRI we indlala pituitary - lena indlela enembile kakhulu futhi iningi ulwazi zophenyo

Ubuchopho bomuntu imayelana 2% kuphela isisindo ingqikithi emzimbeni. Indlala pituitary - ucezu oluncane lwensimbi ezansi kobuso ubuchopho, - une ngisho kancane. isisindo salo siyahlukahluka, ubude 0,35-0,65 yona 10 ml, mayelana 15 ml ububanzi futhi ukuphakama ml 5-6 kuphela. Kukho konke lokhu pituitary ke inezingxenye ezimbili, front futhi bakhulise. Ngamunye wabo yenza amahomoni yayo futhi unesibopho izinqubo ezahlukene umzimba.

Ukuze overestimate ukubaluleka pituitary kunzima, ngoba kuthinta indlala yegilo, cortex adrenal, ukukhula komuntu, umsebenzi gonads, izinso futhi imithambo yegazi, okusho ukuthi unesibopho ukusebenza evamile zethu zomzimba.

Uma usola ukuthi lokhu kuwuphawu lwesimila ezibalulekile ndlala, odokotela linqume i-MRI we pituitary. Pituitary isimila ngokuthi i adenoma. Kungenzeka abafika kwabangu-10 ml (microadenomas) futhi ezingaphezu kuka-10 ml (macroadenoma).

Kunezinhlobo eziningana lwesimila. Ukwahlukanisa lwenzeka histological, isb izicubu imingcele emsebenzini hormone, isb anda noma lehla uketshezi-hormone, kanye Ithumba ingozi noma abulalayo. Kulo mBhalo, isikhathi ukubeka okuyikona kulondoloza ukuphila kwayo le ndoda. Kuzo zonke izindlela ezikhona njengamanje lokuhlolwa MRI pituitary kuphela kunikeza isithombe ngokuphelele olunembile kwenzekani nge indlala.

Izimpawu adenoma pituitary zingase zihluke, kuye ngohlobo lwesimila kanye isiqondiso ekukhuleni kwayo. Iqiniso ukuthi indlala pituitary itholakala uhlobo ithambo ephaketheni, okuthiwa the sehhashi Turkish. Uma adenoma ikhula phansi esifubeni sphenoid ithambo sehhashi, isiguli ekhononda of umuzwa acinene ukuminyana. Uma ukucindezelwa isimila esihlalweni diaphragm, isiguli ikhanda njalo ebunzini, amathempeli ngemva kwamehlo. Ngokuvamile zibuthuntu ubuhlungu, ngaphandle isicanucanu amaphilisi isuswe kanzima. Ngaphezu kwalokho, iziguli sihlangabezane ukuwohloka abukhali umbono kanye endocrine iziyaluyalu. Isifo sikashukela insipidus kungabuye kubangelwa isimila se-Lobe posterior we indlala pituitary.

Kuye isifo emitholampilo babelwa izinhlobo ezahlukene yokuhlolwa, kuhlanganise ukuhlolwa yokunquma inani lama-hormone serum craniography, izindlela radioimmunoassay, ihlola thyrotropin nge sinaktenom futhi pituitary MRI. Kuphela okuyinkimbinkimbi kwazo zonke izinto imiphumela, ungakwazi wafaka le uphethwe wokugcina.

Uma kusolakala ukuthi isimila kuyinto abulalayo, i-MRI nge Ngokuphambene wenziwa. Ngenxa yalesi examinee emthanjeni paramagnetic Ngokuphambene ejenti iphathwa, ukuvumela umbono ocacile ngezindinganiso ubukhulu unesimila ukuma imiphetho yayo.

Ezinye iziguli bayesaba ukwenza i-MRI. Eqinisweni, lena eyodwa yezindlela ingozi kakhulu luhlolo. Kuyini imaging empeleni? Lena elwa sokuqhafaza isitho siphenywa, kodwa hhayi ngokuphelele, njengoba e X-ray, futhi izingqimba, sengathi umzimba nge nommese uthathe eziningi izingqimba mncane futhi ukuhlola ngalinye. Yiqiniso, ngesifo indlela enjalo isithombe esinembile. Ngo-magnetic resonance imaging usebenzisa ama-athomu ye-hydrogen samanje ngamanani amakhulu kuzo zonke imizimba yethu. Indlela abasabela ngayo kulokho kagesi ukuphazamiseka amagagasi imvamisa ezithile isithombe jikelele umzimba yombambiqhaza.

pituitary MRI kanye nobuchopho MRI kukhona izinqubo ezimbili ezihlukene, ukuthi pituitary ngoba ubukhulu lincane kakhulu, futhi isithombe olunembile isimo isithombe Icwele udinga ukwenza "zingcezu" ngokusebenzisa 1-2 amamilimitha angu. Inqubo yokuhlola ngokuphelele kobuhlungu, zibalwa ngu isikhathi ngaphandle nalokho isigamu sehora, futhi umehluko - ngehora. Enye inzuzo enkulu ka indlela ukuthi akusho irradiate umzimba, ngakho-ke kungaba kwenziwe ngokuphindaphindiwe futhi ngaphandle ukulinyazwa abantu. Kodwa ukulinganiselwa vo sisekhona. Ngokwesibonelo, i-MRI akuyona eyenziwa izingane kuze iminyaka 7 futhi, abantu banda ukugcwala (isisindo 180 kg).

Ngaphezu pituitary izimila, izifo ezingathi sína ebuchosheni. Ngenhlanhla, kukalutshwana kakhulu. Izimpawu zalesi sifo iyashiyana kwasendaweni isayithi, Ubungako, ukukhula rate kanye kumiswa abanye. Ezimweni eziningi, ikakhulukazi kusaqalwa isifo, izimpawu abasakwazi ezingacacile. Kuyinto efanayo ukuze izimpawu ezinye izifo, ezifana ubuthakathaka jikelele, ukukhathala, ukuphathwa ikhanda, angaboni kahle, inkumbulo, ukulahlekelwa ukuzwa, isiyezi kanye nabanye abaningi. Kususelwa isithombe emitholampilo ye isifo, omiswe ubuchopho luhlolo, kuhlanganise ezihlukahlukene cwaningo, izivivinyo, i-MRI ubuchopho, CT. Kwezinye ezinye izifo zobuchopho eyenziwa ultrasound, okuyinto ayinangozi ngokuphelele, futhi ultrasonography cranial.

Ngamunye wethu kumelwe akhe khumbulani, ngaphambili lesi sifo lutholwa, aba maningi amathuba okuba alulame ngokugcwele.
