Garrett seems to love using centrifugal compressors in their turboshaft engines, and the incredibly versatile Allison Model 250 turbo-shaft uses both an axial compressor for the 'low-pressure' side, and a centrifugal compressor for the 'high-pressure' side.
The only turbofan engine that comes to mind that uses a centrifugal compressor now-adays is a Garrett design, though the designation escapes me.
Is that the one used on the Mitsubishi Mu-2 turboprop?
