    Computer assessment of neurodegeneration in Parkinson disease using data fusion techniques with MR images
    (2003) Raff, U; Rojas, GM; Huete, I; Hutchinson, M
    Rationale and Objectives. Recently developed MR imaging techniques using inversion recovery are a sensitive tool to identify and quantify morphologic changes in the substantia nigra due to neurodegeneration. Using a semi-automated computer segmentation technique to isolate the substantia nigra pars compacta (SNC), we propose a colored image fusion technique to visually assess the sites of damage in the SNC and integrate the information obtained from two implemented inversion-recovery sequences.
