We present recent results comparing the CO and HI dynamics of nearby galaxies that have been observed as part of the THINGS (HI) and the HERACLES (CO) surveys. We focus on 3 galaxies out of the 11 that have been analysed so far, and present velocity-fields and rotation curves of the CO, which we compare with that of the HI.
