AB: The main goal of the STEREO mission is to address the three-dimensional structure of the Sun's corona, with emphasis in the origin and development of coronal mass ejections (CMEs). SECCHI/EUVI, the extreme ultraviolet imager onboard STEREO, provides full Sun coverage with improved cadence and spatial resolution with respect to SOHO/EIT. This allows an improved study of CME signatures in EUV. The present work provides an insight analysis of CME related phenomena in the EUV, such as filaments and post-eruptive arcades. By combining simultaneous images from both spacecraft, information on the 3D configuration of the solar structures can be obtained. The identification of the same feature in both images and the calculation of the displacement between them (parallax) are used to obtain the height of the structures seen in EUV images.
