Applying the Casson-Gordon signature invariants of double branched covers, the author proves that an odd 3-strand pretzel knot is topologically slice if and only if either it is ribbon or has trivial Alexander polynomial, and that most topologically slice even 3-strand pretzel knots must be ribbon.
