There are short T2 components in the white matter which can not be detected with conventional magnetic resonance imaging sequences. We present an ultrashort TE imaging pulse sequence which combines half pulse excitation and spiral sampling. The ultrashort T2 components in the white matter were selective depicted with an ultrashort echo time of 8 usec, while the long T2 components were suppressed using a long slice selective inversion pulse and dual-echo echo subtraction.
