Subject-specific bone attenuation correction for brain PET/MR: can ZTE-MRI substitute CT scan accurately?

Abstract

In brain PET/MR applications, accurate attenuation maps are required for accurate PET image quantification. An implemented attenuation correction (AC) method for brain imaging is the single-atlas approach that estimates an AC map from an averaged CT template. As an alternative, we propose to use a zero echo time (ZTE) pulse sequence to segment bone, air and… (More)
