Tekereza ko inshuti yawe irimo kubagwa kugira ngo ikureho ikibyimba mu gice cy’ubwonko kigoye cyane. Abaganga bitonze cyane mu kubaga. Ariko se bamenya bate niba ikibyimba cyarakuweho burundu cyangwa niba hari agace gato gasigaye? Nyuma yo kubagwa, niba wongeye gukora scan nyuma y'iminsi mike, ushobora kumenya neza. Niba hari agace gato gasigaye, uzagomba gukora akandi kubaga, si byo se? Iri koranabuhanga ridasanzwe tuvuga uyu munsi rikoreshwa nk'igisubizo cy'ibibazo nk'ibyo.
Mu magambo make, iMRI ni iki?
Izina ryuzuye rya iMRI ni Intraoperative Magnetic Resonance Imaging . "Intraoperative" bivuga "mu gihe cyo kubaga." Ibi bivuze ko ari scan ya MRI ikorwa mu gihe cyo kubaga . Ibi bituma itsinda ryawe rishinzwe kubaga ribona neza ingingo, ingingo, n'ibindi bintu biri mu mubiri wawe mu gihe cyo kubaga.
Tekereza umuganga arimo gukuramo ikibyimba mu bwonko. Ashobora gukora scan ya MRI ako kanya nyuma yo gukuraho ikibyimba, mbere yuko igikorwa kirangira, kugira ngo arebe ati: "Ese nakuyeho ikibyimba cyose? Cyangwa hasigaye uduce duto?" Iyo scan igaragaje ko hari agace gato gasigaye, ashobora guhita akuraho icyo gice.
Akamaro gakomeye k'ibi ni uko kumenya ko hari ibice bya kanseri bisigaye nyuma yo kubagwa bishobora kugabanya cyane ibyago byo kubagwa bwa kabiri.
Ni irihe tandukaniro riri hagati ya MRI isanzwe na iMRI?
Itandukaniro nyamukuru kandi ryonyine riri hagati y'ibyo byombi ni igihe bifata kugira ngo bikorwe .
- MRI isanzwe: Ibi bikorwa kugira ngo hamenyekane indwara cyangwa hategurwe kubagwa. Ujya mu mashini ya MRI nk'uko bisanzwe hanyuma ugakora iyi scan.
- IMRI: Ibi bikorwa mu gihe cyo kubaga , imbere mu cyumba cyo kubaga.
Mu magambo make, kimwe gikorwa mbere y'uko igikorwa kirangira, ikindi gikorwa mu gihe cy'igikorwa ubwacyo.
Kuki abaganga bakoresha iri koranabuhanga mu gihe cyo kubaga?
Kubaga bimwe na bimwe, cyane cyane kubaga ubwonko, biragoye cyane. Ndetse n'itandukaniro rya milimetero imwe rishobora kugira ingaruka zikomeye. Mu gihe cyo kubaga, umuganga akeneye ishusho isobanutse neza kandi igaragara kurusha iyo ashobora kubona n'amaso ye cyangwa akoresheje mikorosikopi. Icyo gihe ni bwo agaciro ka iMRI kaba gasobanutse neza.
Dore zimwe mu nzira zikunze gukoreshwa cyane mu ikoranabuhanga rya iMRI:
| Ubwoko bw'ukubaga | Ubufasha buturuka kuri iMRI |
|---|---|
| Gukuraho ikibyimba cyo mu bwonko | Kwemeza niba ikibyimba cyarakuweho burundu, cyangwa niba ibice byinshi bishobora gukurwaho hatabayeho kwangiza ingingo nzima. Ibi ni ingenzi cyane cyane mu bibyimba nka glioma . |
| Ikibyimba cy'umuyoboro w'amaraso | Mu gihe cyo gukuraho ibibyimba bikikije agahu k'ubwonko, igice cy'ubwonko cyoroshye cyane, kugira ngo urebe niba nta byangiritse ku mitsi n'imitsi y'amaraso by'ingenzi biri hafi aho. |
| Gukangura Ubwonko Bwimbitse (DBS) | Mu gihe ushyira electrodes mu bwonko mu ndwara nka Parkinson , menya neza ko zishyizwe ahantu hakwiye. |
| Kubaga indwara y'igicuri | Gutahura neza igice kidasanzwe cy'ubwonko gitera igicuri no kureba niba cyarakuweho burundu. |
| Otomiyo y'inyuma (craniotomy) | Mu kubaga kose gukomeye ku bwonko, kugira ngo barebe uko ubwonko bumeze (kubyimba, kuva amaraso) mu mpera z'ukubaga. |
Iyi mashini ya iMRI ikora ite?
MRI scan ni imashini ikoresha magnets na radio waves kugira ngo ifate amafoto y'imbere mu mubiri. Ibyo ni byo biba muri iMRI. Ntuzabyumva kuko uri munsi y'ikinya kandi akenshi ntugire icyo umenya.
Dore uko bikora, mu magambo make:
Igice kirenga kimwe cya kabiri cy'imibiri yacu kigizwe n'amazi. Amazi agizwe na atome za hydrogen na ogisijeni. Muri iyi atome ya hydrogen harimo agace kitwa porotoni . Izi porotoni zifite umuriro w'amashanyarazi, kandi nazo zirazenguruka.
Imashini ya MRI yohereza imbaraga zikomeye za rukuruzi mu mubiri wawe. Icyaba gihari ni uko izi protoni zose mu mubiri wawe zigenda zigana mu cyerekezo kimwe, nk'urushinge rwa busole rwerekeza mu majyaruguru.
Hanyuma, imashini ya MRI yohereza umuraba w’imiraba ya radiyo muri iyo ngufu ya rukuruzi. Ibi bimeze nk'icyuma gifunga kamera ifata ifoto. Iyi miraba ya radiyo ihagarika akanya gato imiterere ya protoni. Iyo imiraba ya radiyo ihagaze, protoni zisubira ku murongo wazo wa mbere. Iri hinduka rifatwa na scanner iri muri iyo mashini. Amakuru yoherezwa kuri mudasobwa, bigatuma ishusho igaragara neza mu mpande eshatu (3D).
Ni gute nakwitegura iMRI?
Mu by’ukuri, ntabwo ukeneye kwitegura iMRI kuko bibaho mu gihe cyo kubagwa kwawe. Icyo ukeneye gukora ni ukwitegura neza kubagwa kwawe. Kurikiza amabwiriza ya muganga wawe nk’uko azakubwira.
Uzaba uri munsi y'ikinya mu gihe cyo kubagwa, bityo ushobora kuba usinziriye. Hazabaho urusaku igihe icyuma cya MRI gikora, ariko ntuzumva kubera ikinya. Hari igihe habaho uburyo bwo kuba uri maso. Muri ibyo bihe, itsinda ry'abaganga rizagutegurira igikorwa kandi rikurebere neza ko umerewe neza mu gihe cyo gupimwa.
Ibintu ugomba kubwira muganga wawe mbere yo kubagwa:
- Ni ukuvuga niba utwite .
- Niba ufite ikintu cy'icyuma cyashyizwe mu mubiri wawe. Urugero, pacemaker, ibyuma byashyizwe mu mubiri, ingingo z'ubukorano, nibindi. Ingufu zikomeye muri MRI zishobora gutuma zigenda cyangwa zikora nabi. Ibi ni akaga. Kubwibyo, niba ubibwiwe mbere y'igihe, itsinda ry'abaganga rizafata ingamba zikenewe zo kwirinda.
- Mbere yo kubagwa, ugomba gukuramo ibintu byose by'icyuma ku mubiri wawe, nk'imitako , amaherena, imigozi y'imisatsi, n'insinga z'icyuma ziri mu myenda yawe y'imbere .
Ni izihe nyungu zo gukoresha iMRI?
Hari ibyiza byinshi by'ingenzi byo gukoresha ikoranabuhanga rya iMRI.
- Amashusho asobanutse neza: Agace k'umubiri urimo kubagwa kagaragara neza kandi mu buryo burambuye.
- Amakuru aboneka mu gihe nyacyo: Aya mashusho ashobora kurebwa mu gihe cyo kubagwa, bigatuma ibyemezo bifatwa vuba.
- Gusuzuma impinduka: Ushobora kubona ako kanya uko agace kahindutse mu gihe cyo kubagwa (urugero: nyuma yo gukuraho ikibyimba).
- Kwirinda ingorane: Aya mashusho asobanutse neza ashobora kugabanya cyane ingorane zishobora kubaho nyuma yo kubagwa.
- Ntikoresha imirasire: Ikoranabuhanga rya MRI ntirikoresha imirasire nka X-ray cyangwa CT scans, bityo ntiryangiza umubiri.
Muganga ashobora kubona ibi bisubizo mu masegonda make nyuma yo gupimwa, bigatuma akomeza intambwe ikurikiraho yo kubagwa nta gutinda.
Ubutumwa bwo kujyana mu rugo
- iMRI ni scan yihariye ya MRI ikorwa mu gihe cyo kubaga.
- Intego nyamukuru y'ibi ni uguha abaganga bakora operasiyo amahirwe yo kubona neza imbere mu mubiri no kubaho.
- Ibi bifasha kwemeza ako kanya niba ikibyimba cyarakuweho burundu, cyane cyane mu kubagwa bigoye nko gukuraho ikibyimba cyo mu bwonko.
- Ibi bigabanya cyane gukenera kubagwa bwa kabiri.
- Niba ugiye kubagwa ukoresheje iMRI, menya neza ko wamenyesheje muganga wawe mbere y'igihe ibikoresho by'icyuma, nk'ibikoresho bifasha mu guhagarara kw'imitsi, washyize mu mubiri wawe.
