Long-baseline interferometers at Jodrell Bank have been used to investigate the radio structures of 101 quasar candidates from the Parkes 2700-MHz survey of the + or - 4-deg declination zone. These observations show that quasars with flat or inverted radio spectra have radio structures which are smaller than 0.1 arcsec. The steep-spectrum quasars from the Parkes sample are more extended and have a distribution of angular sizes similar to that of quasars of the same spectral type identified from the lower-frequency 4C catalogue. All 10 of the quasars with concave spectra have radio emission from the vicinity of the optical nucleus, usually from regions smaller than 0.1 arcsec.
