MRI of pituitary shwanu - iyi ndiyo nzira yakarurama uye kupfuura mashoko kupfuura kuongorora

Uropi hwomunhu ndicho chete anenge 2% of zvachose kurema muviri. The pituitary shwanu - dukuduku piece simbi pazasi pemvura uropi, - une kunyange zvishoma. uremu Its zvinyamusi, kureba 0,35-0,65 kuti 10 Rine mamiririta, vanenge 15 ml ane upamhi uye kureba Rine mamiririta 5-6 chete. In zvose pituitary ino ine zvikamu zviviri, mberi uye neshure. Mumwe nomumwe wavo pave hormone ayo uye ndiye pezvakaitwa siyana mune nhengo.

Kuti kuona kukosha pituitary kwakaoma, nokuti zvinokanganisawo thyroid shwanu, adrenal cortex, kukura kwevanhu, basa gonads, itsvo uye nemidziyo ropa, zvinoreva zviri anokonzera kuipa kushanda muviri wedu hurongwa.

Kana uchifungidzira kuti shwanu bundu iri rinokosha, vanachiremba vanonyorera MRI pamusoro pituitary. Pituitary bundu anonzi adenoma. Zvingava kusvika 10 Rine mamiririta (microadenomas) uye vanopfuura 10 Rine mamiririta (macroadenoma).

Kune mhando wandei bundu. Kupatsanura anotora nzvimbo pamusoro histological, i.e. zvinyama parameters pamusoro hormone basa, i.e. hwakawedzera kana ungaderedza secretion kuti hormone, uye bundu iri benign kana akaipa. Mukupera nyaya, nguva kuisa zvakarurama zvokuongorora anoponesa upenyu hwomunhu. Vose huripo pari nzira rokuongorora chete pituitary MRI anopa mufananidzo zvachose yakarurama zviri kuitika chete shwanu.

Zviratidzo zvechirwere pituitary adenoma angava akasiyana, zvichienderana norudzi bundu uye nhungamiro kukura kwayo. Chokwadi chokuti pituitary shwanu iri mune imwe mhando remafupa muhomwe, unonzi ari Turkish Chigaro. Kana adenoma inokura pasi mukati pachipfuva sphenoid mapfupa Chigaro, murwere anonyunyuta unonzwa nasal kuzara. Kana bundu pazvisviniro diaphragm chigaro, murwere kugara nomusoro pahuma, temberi uye shure meso. Kazhinji ingaderedza marwadzo, pasina svoto mapiritsi uye kubviswa nesimba. Uyezve, varwere vakaona unopinza Kuipa chiratidzo uye kwemakemikari anobudiswa zvirwere. Chirwere cheshuga insipidus inogona kukonzerwa bundu iri posterior akafukidza pituitary shwanu.

Zvichienderana kunotoda chirwere vanotumirwa siyana bvunzo, kusanganisira kuongorora kuti kuziva uwandu serum mahormone craniography, radioimmunoassay nzira, anoedza thyrotropin pamwe sinaktenom uye pituitary MRI. Chete ari kunzwisisa zvose migumisiro, unogona kuisa rokupedzisira zvawanikwa.

Kana aifungidzira kuti bundu iri nyanyisa, MRI pamwe Mukupesana rinoitwa. Nokuti examinee ichi intravenous paramagnetic musiyano nevasori vari kutarisirwa, vachibvumira kunzwisisa pakati bundu ukuru uye chimiro chayo kumicheto.

Vamwe varwere vanotya kuita MRI. Kutaura zvazviri, izvi chimwe chezvinhu benign nzira bvunzo. Chii kuri chaizvoizvo? Ichi chiratidzo graphical pakati amutsvaka nhengo, asi kwete zvachose, sezvo vari maekisirei, uye akaitwa nhurikidzwa, mutumbi ane scalpel sokuti racherwa dzakawanda dzakatetepa akaturikidzana uye yega. Zvechokwadi, yakadaro nzira chirwere mufananidzo zvikuru yakarurama. In rinobva resonance kuri kushandisa hydrogen maatomu chipo vazhinji mune zvose muviri yedu. Zvakaoneka nezvavakaita pane remagetsi chipingaidzo mafungu imwe maitikiro chinhu vakawanda mufananidzo muviri nyaya yacho.

MRI pituitary uye pfungwa MRI zviri zviviri zvakaparadzana nzira, kuti pituitary nokuti saizi iri dikisa, uye mufananidzo yakarurama mufananidzo mamiriro ayo akaturikidzana vanofanira kuita "zvidimbu" kuburikidza 1-2 millimeters. Kuongorora nzira zirokwazvo nyarara, rakava ne nguva pasina kusiyana hafu yeawa, uye pamwe musiyano - awa. Mumwe mukana guru nzira iri kuti haina irradiate muviri, saka rinogona kuitwa kakawanda uye pasina kukuvadza vanhu. Asi kuitwa ongororo uchiripo. Somuenzaniso, MRI haana kuitwa vana makore 7 uye vanhu vakawedzera kuzara (uremu 180 kg).

Kuwedzera pituitary namamota, zvirwere zvakakomba ndiyo bundu muuropi. Sezvineiwo, zviri apo neapo. Zviratidzo chirwere ichi zvinosiyana zvichienderana localization kwenzvimbo, kukura, kukura mwero uye paumbwe nevamwe. Muzviitiko zvakawanda, kunyanya mukutanga nzendo chirwere, zviratidzo zvikuru kujeka. Zvakafanana zviratidzo zvimwe zvirwere, zvakadai vakawanda simba, kurukutika, kutemwa nomusoro, madzerere, ndangariro, kusanzwa, dzungu uye vamwe vakawanda. Pachishandiswa kunotoda mufananidzo chirwere, anodomwa neMutungamiriri pakuongorora kwouropi, kusanganisira akasiyana-siyana Analyses, nemiedzo, MRI uropi, CT. Mune dzimwe zvirwere uropi akatakurwa Ultrasound, riri zvachose chisingakuvadzi, uye cranial ultrasonography.

Mumwe nemumwe wedu anofanira kurangarira, kwokutanga maperembudzi dzakaonekwa, chikuru mukana zvizere ayo kupora.
