Abstract: We present a relation between the Witt invariants of 3-manifolds and the $hatZ$-invariants. It provides an alternative approach to compute the Witt invariants of 3-manifolds, which were originally defined geometrically in four dimensions. We analyze various homology spheres including a hyperbolic manifold using this method.
