Double inversion recovery sequence
Updates to Article Attributes
Body
was changed:
MRI sequences that is used to suppress signal from the CSF as well as from the white matter and hence enhances any inflammatory lesion.
To obtain such sequence in 3T MRI scanner, two inversion times are required. TI1 which is used for suppression of CSF and usually obtained at 2000-3000 msec and TI2 which is used for white matter at 450 msec.
Its main application is to delineate white matter plaques in Multiple sclerosis, estimate lesion load, differentiate juxta cortical from mixed grey matter-white matter plaques and detect infra tentorial or spinal cord lesions.
