CT imaging of wet specimens from a pathology museum: How to build a "virtual museum" for radiopathological correlation teaching.
X-rays and CT have been used to examine specimens such as human remains, mummies and formalin-fixed specimens. However, CT has not been used to study formalin-fixed wet specimens within their containers. The purpose of our study is firstly to demonstrate the role of CT as a non-destructive imaging method for the study of wet pathological specimens and secondly to use the CT data as a method for teaching pathological and radiological correlation. CT scanning of 31 musculoskeletal specimens from a pathology museum was carried out. Images were reconstructed using both soft-tissue and bone algorithms. Further processing of the data produced coronal and sagittal reformats of each specimen. The container and storage solution were manually removed using Volume Viewer Voxtool software to produce a 3D reconstruction of each specimen. Photographs of each specimen (container and close-up) were displayed alongside selected coronal, sagittal, 3D reconstructions and cine sequences in a specially designed computer program. CT is a non-destructive imaging modality for building didactic materials from wet specimens in a Pathology Museum, for teaching radiological and pathological correlation.
