Summary The aim of this study was to provide a detailed anatomical description of the thoracic region features in normal common ( D elphinus delphis ) and striped dolphins ( S tenella coeruleoalba ) and to compare anatomical cross‐sections with computed tomography ( CT ) and magnetic resonance imaging ( MRI ) scans. CT and MRI were used to scan 7 very fresh by‐caught dolphin cadavers: four common and three striped dolphins. Diagnostic images were obtained from dolphins in ventral recumbency, and after the examinations, six dolphins were frozen (−20°C) and sliced in the same position. As well as CT and MRI scans, cross‐sections were obtained in the three body planes: transverse (slices of 1 cm thickness), sagittal (5 cm thickness) and dorsal (5 cm thickness). Relevant anatomical features of the thoracic region were identified and labelled on each section, obtaining a complete bi‐dimensional atlas. Furthermore, we compared CT and MRI scans with anatomical cross‐sections, and results provided a complete reference guide for the interpretation of imaging studies of common and striped dolphin's thoracic structures.
