No need to open the jar: a comparative study of Magnetic Resonance Imaging results on fresh and alcohol preserved common carps (Cyprinus carpio (L. 1758), Cyprinidae, Teleostei).
Magnetic Resonance Imaging (MRI) examinations have been conducted both on fresh and alcohol-preserved common carps (Cyprinus carpio). The images have been compared to those of a sagittally-cut frozen animal of the same species. This work shows that the images obtained are globally similar, and that the MRI technique can be applied to investigate the gross anatomy of alcohol-preserved specimens without destroying them. Unfortunately, this kind of study does not provide precise enough anatomical data for small specimens (less than 10 cm in total length) with a 1 Tesla magnetic field. Nevertheless, leaving the specimen in the jar during MRI examinations does not affect the quality of the final images.
