VIRTOPSY- A REVIEW Dr. Arvind Kumar Senior Demonstrator Deptt. Of Forensic Medicine UCMS DELHI

VIRTOPSY Coined by Dr. Michael J Thali et al VIRTOPSY= virtual + Autopsy

Essentials of virtopsy Multi-slice Computed Tomography (MSCT) Magnetic Resonance Imaging (MRI) Magnetic Resonance Spectroscopy 3-D/ CAD Photogrammetry

Figure showing comparison of spectrum from a human brain with a PMI of about 520 hours (a) and one with a PMI of 57 hours (b)

Merits and Demerits Merits * observer independent * reproducible * non invasive * illustrative visualization * forensic telemedicine consultation

Demerits * MRI was unable to # image coronary artery lesions # differentiate thrombus from postmortem clot # differentiate pulmonary oedema from pneumonic exudates # detect perinatal cardiac malformations

* lack of validation * interpretative problems in advanced decomposition * considerably high costs * time consuming

Conclusion The conventional method of Autopsy is still the gold standard The use of imaging technology should be an autopsy adjunct rather than a replacement
