Abstract Let A be a bounded hereditary Noetherian prime ring. For an A-module M A , we prove that M is a finitely generated projective $${A \mathord{\left/ {\vphantom {A {r\left( M \right)}}} \right. \kern-\nulldelimiterspace} {r\left( M \right)}}$$ -module if and only if M is a $${\pi }$$ -projective finite-dimensional module, and either M is a reduced module or A is a simple Artinian ring. The structure of torsion or mixed $${\pi }$$ -projective A-modules is completely described.
