THEIRMKwakwalwa (hoton maganadisu na maganadisu) jarrabawa ce da za ta iya gano abubuwan da ba su dace ba a cikin kwakwalwa kuma su tantance sanadin (jiniyoyin jini, cututtuka, lalata, kumburi ko ƙari).

MRI yana ba da damar iya gani:

• Bangaren zahiri (fararen al'amarin). kwakwalwa

• the deep end (grey matter)

• ventricles

• venous da arterial jini wadata (musamman lokacin amfani da rini)

A lokuta da yawa, MRI yana ba da bayanan da ba za a iya gani ta wasu fasahohin nazarin hoto ba (radiography, duban dan tayi ko ma ƙididdiga). MRI yana amfani da filin maganadisu da raƙuman radiyo don hange dukkan kyallen da ke cikin jirage uku na sarari.

Ana yin MRI na kwakwalwa don dalilai na bincike. Gwajin zabi ne ga duk cututtukan kwakwalwa. Musamman, an wajabta shi:

• domin sanin dalilin ciwon kai

• don tantancewa jinin jini ko gaban jinin jini zuwa kwakwalwa

• idan akwai rudani, rashin fahimtar juna (wanda ke haifar da misali da cututtuka irin su Alzheimer ko Parkinson)

• idan 'hydrocephalus (tarawar ruwan cerebrospinal a cikin kwakwalwa)

• don gane gaban ka mutu, nacututtuka, ko maƙurji
• idan akwai demyelinating pathologies (kamar mahara sclerosis), don ganewar asali ko saka idanu
• a yayin da rashin daidaituwa ya haifar da zato ga lalacewar kwakwalwa.

Don MRI na kwakwalwa, majiyyacin yana kwance a baya akan kunkuntar tebur mai iya zamewa cikin na'urar silinda wacce aka haɗa ta. 

An yi jerin raguwa da yawa, bisa ga duk tsare-tsaren sararin samaniya. Yayin da ake ɗaukar hotuna, injin zai yi ƙara mai ƙarfi kuma mai haƙuri dole ne ya guje wa kowane motsi don samun ingantattun hotuna masu inganci.

Ma'aikatan kiwon lafiya, waɗanda aka sanya a cikin wani ɗaki, suna sarrafa saitunan na'urar kuma suna sadarwa tare da majiyyaci ta makirufo.

A wasu lokuta (don duba yanayin jini, kasancewar wasu nau'ikan ciwace-ciwacen daji ko don gano wani yanki na kumburi), ana iya amfani da kayan rini ko bambanci. Sannan a yi ta allurar a cikin jijiyoyi kafin jarrabawa.

Jarabawar tana ɗaukar lokaci mai tsawo (minti 30 zuwa 45) amma ba ta da zafi.

Brain MRI yana bawa likita damar gano kasancewar, a tsakanin sauran abubuwa:

• an tumo

• zubar jini ko kumburi (edema) a ciki ko wajen kwakwalwa

• an kamuwa da cuta ko a kumburi (meningitis, encephalitis)

• rashin daidaituwa wanda zai iya nuna kasancewar wasu cututtuka: cutar Huntington, sclerosis mai yawa, cutar Parkinson ko cutar Alzheimer.

• kumbura (ciwon kai) ko rashin samuwar hanyoyin jini

Dangane da ganewar asali wanda zai kafa bisa ga hotunan MRI, likita na iya ba da shawarar magani mai dacewa ko tallafi.
