“…I n humans, the use of cross‐sectional postmortem imaging for medicolegal investigations or virtual imaging has rapidly expanded over the past 15 years and is now routine in many jurisdictions . Veterinary forensic radiology and imaging research has focused on postmortem imaging and identifying radiographic features of nonaccidental trauma; how e ver, research opportunities and practical applications of forensic radiology and imaging in veterinary medicine are abundant and growing . Imaging studies are often provided as evidence in medicolegal investigations involving humans or animals.…”

Imaging studies are often of evidentiary value in medicolegal investigations involving animals and the role of the veterinary radiologist is to interpret those images for courts as an expert or opinion witness. With progressing interest in prosecuting animal crimes and strengthening of penalties for crimes against animals, the participation of veterinary radiologists in medicolegal investigations is expected to increase. Veterinary radiologists who are aware of radiographic and imaging signs that result in animal suffering, abuse, or neglect; knowledgeable in ways radiology and imaging may support cause of death determinations; conversant in postmortem imaging; comfortable discussing mechanisms and timing of blunt or sharp force and projectile trauma in imaging; and prepared to identify mimics of abuse can assist court participants in understanding imaging evidence. The goal of this commentary review is to familiarize veterinary radiologists with the forensic radiology and imaging literature and with the advantages and disadvantages of various imaging modalities utilized in forensic investigations. Another goal is to provide background information for future research studies in veterinary forensic radiology and imaging.

“…Finally, imaging techniques have been employed experimentally in animal models, in the estimation of time since death. 9,41,42 With modern digital imaging techniques of whatever kind, the images can be securely stored locally or by use of a central storage facility and can be retrieved and viewed at a later date, even after disposal of the cadaver. 11 Postprocessing techniques are investigator independent and objective and accessible for audit.…”

Investigation of animal-related crime, and therefore submission of forensic cases to veterinary pathology facilities, is increasing, yet many veterinary pathologists are unfamiliar and often uncomfortable with involvement in the forensic necropsy. This article discusses various aspects of the forensic necropsy without specific attention to any particular species group or crime. General advice is given on procedures, documentation, and recording of the examination, and the article indicates how these features may differ from those used in investigation of natural disease. It also discusses evidence management, including recordkeeping, identification of evidence, labeling of photographs, and use of standard operating procedures and protocols. Various written and visual methods for documentation of the forensic necropsy are covered, and adjunctive topics such as sample collection, assessment, and description of wounds and taphonomy are included. Cause, mechanism, and manner of death are defined, and guidance to the use of these terms is given. The aim of this article is to offer guidance on procedural aspects of the forensic necropsy that will help those developing their forensic services, contribute to standardization of the provision of forensic veterinary pathology, and build the confidence of the ''uncomfortable'' forensic veterinary pathologist.

“…However, the number of live finless porpoises available for ultrasound imaging is limited, since captive animals in commercial aquaria are scattered and behavioral training must be undertaken before ultrasound examinations can be performed (Brook 2001). The alternative and more traditional, often unpleasant, and laborious method involves necropsy of carcasses (that are prone to rapid decomposition, especially when laboratories are far away from the field) (Ryg et al 1990;Heng et al 2009). Postmortem abdominal ultrasonography is generally considered to be of limited or no value, particularly for highly decomposed cadavers because gas rapidly accumulates in the gastrointestinal tract and blood vessels (Charlier et al 2013;Heng et al 2009).…”

Postmortem abdominal ultrasonography is generally considered to be of limited or no value, particularly for highly decomposed cadavers because gas rapidly accumulates in the gastrointestinal tract and blood vessels (Charlier et al 2013;Heng et al 2009). Nevertheless, we explore the possibility that ultrasound images of blubber might provide meaningful data, given that abdominal gases might not have the same effect on these tissues in fresh carcasses.…”

Background: Blubber has many functions, among which energy storage, thermoregulation, buoyancy, and hydrodynamic streamlining are the most frequently cited. Within and between taxa, variations in its structure and distribution likely reflect different adaptations of a species to its life history requirements, environment, health, and function. Here, we use ultrasound to describe the distribution of blubber in the finless porpoise (Neophocaena asiaeorientalis sunameri) based on examinations of 34 fresh cadavers recovered as accidental fisheries bycatch. Results: Measurements of blubber depth determined by ultrasound positively correlated with conventional measurements using a scalpel and calipers. Whereas conventional surgical incision and visual examination revealed two layers of blubber, ultrasound revealed up to three layers; thus, ultrasound reveals additional structural detail in blubber while crude necropsy techniques do not. Across life history categories, ultrasound revealed the distribution of inner blubber to be topographically consistent with that of full-depth blubber. Blubber in the dorsal region was stratified into three layers and was significantly thicker than that in the lateral and ventral regions, in which a middle layer was normally absent.
