Twenty quasars from the Large Bright Quasar Survey (LBQS; Hewett et al. 1995, AJ, in press) have been imaged with the VLA in the A configuration to study their radio morphologies as part of an ongoing investigation of the radio properties of optically selected quasars. The targets, which range in redshift from 0.4 to 2.7, were selected from a snapshot detection survey of 1/4 of the 1000+ quasars in the LBQS (Hooper et al. 1995, ApJ, in press). The majority of the quasars imaged at high resolution are strongly core dominated, with some showing little or no extended emission. This contrasts with the recent results for the Bright Quasar Survey (Kellermann et al. 1994, AJ, 108, 1163), in which the core fraction is more uniformly distributed.
