Hoton hoton maganadisu na lumbar (MRI) yana amfani da kuzari daga maganadisu masu ƙarfi don ƙirƙirar hotunan ƙananan ɓangaren kashin baya (lumbar spine).

MRI baya amfani da radiation (x-rays).

Ana kiran hotunan MRI guda ɗaya yanka. Ana iya adana hotunan a kan kwamfuta ko a buga su a fim. Examaya daga cikin jarrabawa yana samar da hotuna da yawa.

Gwaje-gwaje masu alaƙa sun haɗa da:

  • Cervical MRI scan (wuyan MRI)
  • MRI

Za ku sa rigar asibiti ko tufafi ba tare da karfen ƙarfe ko zikwi ba (kamar su wando da t-shirt). Tabbatar kun cire agogo, kayan ado da agogo. Wasu nau'ikan ƙarfe na iya haifar da hotuna marasa haske.

Za ku kwanta a kan kunkuntar tebur wanda yake zamewa a cikin babban bututu mai kama da rami.

Wasu jarrabawa suna buƙatar fenti na musamman (bambanci). Mafi yawan lokuta, zaka samu rini ta jijiya (IV) a hannunka ko hannu kafin gwajin. Hakanan zaka iya samun fenti ta hanyar allura. Rini yana taimaka wa masanin ilimin radiyo ganin wasu yankuna sosai.

A lokacin MRI, mutumin da ke aiki da injin ɗin zai kalle ku daga wani ɗakin. Jarabawar galibi tana ɗaukar minti 30 zuwa 60, amma na iya ɗaukar lokaci mai tsayi.


Ana iya tambayarka kada ka ci ko sha wani abu na awanni 4 zuwa 6 kafin hoton.

Faɗa wa mai kula da lafiyar ku idan kuna jin tsoron ɓoyayyun wurare (suna da claustrophobia). Za a iya ba ku magani don taimaka muku jin bacci da ƙarancin damuwa. Mai ba da sabis naka na iya ba da shawarar MRI ta "buɗe", a cikin ingin da ba ta kusa da jiki.

Kafin gwajin, gaya wa mai ba ka idan kana da:

  • Shirye-shiryen Bidiyo na Brain aneurysm
  • Wasu nau'ikan bawul na zuciya
  • Ibarfafa zuciya ko bugun zuciya
  • Abun kunne na ciki (cochlear)
  • Ciwon koda ko wankin koda (mai yiwuwa ba za ku iya samun bambanci ba)
  • Kwanan nan aka sanya kayan haɗin wucin gadi
  • Wasu nau'ikan jijiyoyin jijiyoyin jini
  • Yi aiki da ƙarfe a da (kuna iya buƙatar gwaje-gwaje don bincika sassan ƙarfe a idanunku)

Saboda MRI ya ƙunshi maganadisu masu ƙarfi, ba a ba da izinin ƙarfe abubuwa cikin ɗakin tare da na'urar daukar hoton MRI:

  • Alƙalumma, kayan aljihu, da tabarau na iya tashi ko'ina cikin ɗakin.
  • Abubuwa kamar su kayan kwalliya, agogo, katin bashi, da kayan ji zasu iya lalacewa.
  • Pins, zanen gashi, zik din karfe, da makamantan su kayan karafa na iya jirkita hotunan.
  • Ya kamata a fitar da aikin hakori mai cirewa gabanin hoton.

Nazarin MRI ba ya haifar da ciwo. Kuna buƙatar yin kwance har yanzu saboda yawan motsi na iya rikitar da hotunan MRI da haifar da kurakurai.


Tebur na iya zama da wuya ko sanyi, amma zaka iya neman bargo ko matashin kai. Injin yana kunna sauti mai ƙarfi da amo idan aka kunna. Kuna iya sa matosai na kunne don taimakawa wajen toshe hayaniya.

Wata hanyar shiga cikin daki zata baka damar yin magana da wani a kowane lokaci. Wasu MRIs suna da talabijin da belun kunne na musamman waɗanda zaku iya amfani dasu don taimakawa lokacin wucewa.

Babu lokacin warkewa, sai dai idan an baka magani don shakatawa. Bayan binciken MRI, zaku iya komawa tsarin abincinku na yau da kullun, ayyukanku, da magunguna.

Kuna iya buƙatar MRI na lumbar idan kuna da:

  • Backananan ciwon baya ko ƙashin mara wanda baya samun sauki bayan jiyya
  • Weaknessarfin ƙafa, ƙwanƙwasawa, ko wasu alamomin da ba su inganta ko yin muni

Mai ba da sabis ɗinku na iya yin oda MRI na lumbar idan kuna da:

  • Ciwon baya da zazzabi
  • Launin haihuwa na ƙananan kashin baya
  • Rauni ko rauni ga ƙananan kashin baya
  • Painananan ciwon baya da tarihi ko alamun daji
  • Mahara sclerosis
  • Matsalolin sarrafawa ko wofintar da mafitsara
  • Faɗakarwar Disk

Sakamakon yau da kullun yana nufin kashin baya da jijiyoyin da ke kusa sun yi kyau.


Yawancin lokaci, sakamakon sakamako mara kyau shine saboda:

  • Herniated ko "zamewa" faifai (lumbar radiculopathy)
  • Rowididdigar layin kashin baya (stenosis spinal)
  • Rashin al'ada sanye da kasusuwa da guringuntsi a cikin kashin baya (spondylitis)

Sauran sakamako mara kyau na iya zama saboda:

Yi magana da mai baka game da tambayoyinka da damuwa.

MRI ba ya ƙunshi radiation. Babu wani sakamako mai illa da aka ruwaito daga filayen maganadiso da raƙuman rediyo.

Har ila yau, yana da lafiya a yi MRI a lokacin daukar ciki. Babu wani tasiri ko rikitarwa da aka tabbatar.

Mafi yawan nau'in bambancin (dye) da aka yi amfani da shi shine gadolinium. Yana da lafiya. Rashin lafiyan rashin lafiyar wannan rina ba safai ba. Koyaya, gadolinium na iya zama cutarwa ga mutanen da ke da matsalar koda waɗanda ke buƙatar wankin koda. Idan kana da matsalolin koda, da fatan za a gaya wa mai ba ka magani kafin gwajin.

Fieldsananan fannonin maganadisu waɗanda aka ƙirƙira yayin MRI na iya haifar da bugun zuciya da sauran abubuwan haɓaka don ba su aiki sosai. Hakanan yana iya haifar da wasu ƙananan ƙarfe a jikinka suyi motsi ko motsi. Don dalilan tsaro, da fatan kada a kawo wani abu da ya ƙunshi ƙarfe a cikin ɗakin hoton.
