I-MRI ye-pituitary gland yindlela echanekileyo kunye neyona ndlela inolwazi yophando

Ingqondo yomntu i-2% kuphela yesisindo somzimba. Kwi-pituitary gland - intsimbi encinci yesinyithi, ephantsi kwendawo engezantsi yommandla wengqondo - ingaphantsi. Ubunzima bayo buba ngu-0.35-0.65 g. Kufikelela kwi-10 ml ubude, malunga ne-15 ml ububanzi, kwaye u-5-6 ml ubude. Ngaloo nto, i-pituitary gland iqukethe i-lobes ezimbini, yangaphambili nangemva kwayo. Ngamnye wabo uvelisa amahomoni ayo kwaye unoxanduva lweenkqubo ezahlukeneyo ebomini bomzimba.

Kunzima ukugqithisa ukubaluleka kwentsimbi ye-pituitary, njengoko ichaphazela ukusebenza kwegciwane le-thyroid, i-corrox ye-adrenal, ukukhula komntu, umsebenzi wegonads, iintso kunye nemithambo yegazi, oko kukuthi, uxanduva lokusebenza ngokuqhelekileyo kwazo zonke iistim zomzimba wethu.

Ukuba i-tumor ikhunjulwa kule gale ebalulekileyo, oogqirha bayalula i-MRT ye-pituitary. I-tumor ye-pituitary ibizwa ngokuba yi-adenoma. Inokuthi ifike kwi-10 ml (microadenoma) kunye no-10 ml (macroadenoma).

Izidumbu ziyaziwa ngeentlobo ezininzi. Ukwahlula kudlula kwi-histological, oko kukuthi, iiparitha zeempawu, ngokwemisebenzi ye-hormone, oko kukuthi, ukukhululwa kwama-hormone kwandisiwe okanye kwinciphile, kwaye kuyingozi nokuba yi-tumor okanye into embi. Kwimeko yokugqibela, ukuxilongwa ngokuchanekileyo okunikezelwa ngexesha kukugcina ubomi bomntu. Kuzo zonke iindlela ezikhoyo zamanje zoviwo, kuphela i-MRT ye-pituitary inikeza umfanekiso ochanekileyo wento eyenzekayo kwi-gland.

Izibonakaliso nge-pituitary adenoma ziyahluke, kuxhomekeke kuhlobo lwesisu kunye nesalathiso sokwanda kwalo. Inyaniso yokuba i-pituitary gland ihlobo lwesitokhwe lesithambo, elibizwa ngokuba yi- saddle saddle. Ukuba i-adenoma ikhula phantsi, kwi-sinus yethambo le-sphenoid le-saddle, isigulane sikhala ngesigxina sokuxinwa kwamanzi. Ukuba i-tumor icinezela kwisithintelo salo, isigulane sinamahlunu rhoqo ebunzini, etempileni nasemva kwemehlo. Ngokuqhelekileyo le ntlungu ayibuhlungu, ngaphandle kwesicathulo kunye neepilisi zisuswe kakhulu. Ukongezelela, izigulane zinokutshabalalisa ngokukhawuleza kwimbono kunye neengxaki ze-endocrine. I-non-diabetes mellitus nayo ingabangelwa yi-tumor kwi-lobe yangasemva ye-pituitary gland.

Ngokuxhomekeka kwisifo sekliniki, iintlobo ezahlukeneyo zoviwo zimiselwe, kubandakanywa iimvavanyo zokumisela inani lamahomoni kwi-serum yegazi, i-craneography, i-radioimmunoassays, iimvavanyo kunye ne-tiroleiberin, kunye ne-synaktenom kunye neMRI ye-gitulo ye-pituitary. Kuphela kwinkimbinkimbi yazo zonke iziphumo kunokufumana ukuxilongwa kokugqibela.

Ukuba kukho ukukrokra ukuba i- tumor iyingozi, i- MRI yenziwa ngokuphambene. Ukwenza oku, umxholo ujojowe nge-intravenously ngokuphambene namalungiselelo e-paramagnetic, okwenza ukuba ukwazi ukufumana umfanekiso ocacileyo ngobukhulu besisu nesimo semiphetho yaso.

Ezinye izigulane zisoyika ukwenza iMRI. Enyanisweni, le ngenye yeendlela ezininzi zokuhlola. Yintoni i-tomography eqinisweni? Lo mfanekiso ocacileyo welilungu elingaphantsi kophando, kungekhona nje ngo-x-ray, kodwa uluhlu loluhlu, njengokungathi iqumrhu lichithwe nge-scalpel kwiindidi ezincinci kwaye zihlolwe nganye. Kakade, ngale ndlela indlela umfanekiso wesifo uchanileyo. Kwi-imagination yamagnetic resonance, i-athomu ye-hydrogen isetyenzisiweyo, kwinani elikhulu likhoyo kuzo zonke izitho zethu. Ngokwenza kwabo kwiimitha zombane nge-electromagnetic radiation ngamagagasi athile, uwonke umfanekiso wesigqeba esihlolwe sisenziwa.

I-MRI ye-pituitary gland kunye ne-MRI yengqondo yimiqathango emibini eyahlukileyo, kuba umzimba we-pituitary uncinci kakhulu, kwaye kubalulekile ukwenza "ukusika" kwi-1-2 mm ukwenzela ukuba ubonise umfanekiso ochanekileyo welizwe lazo ziqendu. Inkqubo yoviwo ayinaso intlungu, ihlala ngexesha ngaphandle kokungafani nehafu yure, kwaye ngokuchaseneyo-iyure. Enye yeenzuzo ezibalulekileyo zendlela kukuba ayiyixilisi umzimba, ngoko unokuthi uyenze ngokuphindaphindiweyo kwaye ngaphandle kokulimala kancinci kubantu. Kodwa kukho imingcipheko yophando. Ngaloo ndlela, i-MRI ayinakwenziwa kubantwana abangaphantsi kweminyaka engama-7 ubudala kwaye abantu bakhathala kakhulu (ubunzima obungaphezu kwe-180 kg).

Ukongeza kwidumbu lesifo, isifo esibi kakhulu sisifo seengqondo. Ngethamsanqa, kunqabile kakhulu. Iimpawu zesi sifo esinzima zihlukileyo kwaye zixhomekeka kwisayithi sendawo, ubungakanani, izinga lokukhula lemfundo kunye nabanye abaninzi. Kwiimeko ezininzi, ngokukodwa kwizigaba zokuqala zesi sifo, i-symptomatology ingacacanga. Kufana neempawu zezinye izifo, umzekelo, ubuthathaka obuninzi, ukukhathala, intloko, umbono ongenakwenzeka, imemori, ukuva, ukutywabalala kunye nabanye abaninzi. Ngokusekelwe kwiphepha leklinikhi yesifo, uvavanyo lobuchopho luyenziwa, kuquka iimvavanyo ezahlukahlukeneyo, iimvavanyo, i-MRI yobuchopho, i-computed tomography. Ngezinye izifo, i-ultrasound yengqondo iqhutyelwa, engenakubungozi ngokupheleleyo, kunye neurosonography.

Ngamnye wethu kufuneka akhumbule, ngaphambili isifo sibonakalisiwe, amathuba amaninzi okuphilisa ngokupheleleyo.
