1.Estimation of body height from spinal length measurements using post-mortem computed tomographic images
The Malaysian Journal of Pathology 2020;42(3):423-431
Introduction: Post-mortem computed tomography (PMCT) provides information that helps in the
determination of the cause of death and corpse identification of disaster victims. One of the methods
for corpse identification includes assessment of the body stature. There is a lack of post-mortem
imaging studies that focus on the anthropometric assessment of corpses. Our aim was to identify
the relationship between cadaveric spine length and autopsy length (AL) among and autopsy
length (AL) among a Malaysian population and derive a regression formula for the estimation of
corpse body height using PMCT. Materials and Methods: We retrospectively assessed 107 cadavers
that had undergone conventional autopsy and PMCT. We made 5 measurements from the PMCT
that included cervical length (CL), thoracic length (TL), lumbosacral length (LS), total column
length of the spine, excluding the sacrum and coccyx (TCL), and ellipse line measurement of the
whole spine, excluding the sacrum and coccyx (EL). We compared these anthropometric PMCT
measurements with AL and correlated them using linear regression analysis. Results: The results
showed a significant linear relationship existed between TL and LS with AL, which was higher in
comparison with the other parameters than the rest of the spine parameters. The linear regression
formula derived was: 48.163 + 2.458 (TL) + 2.246 (LS). Conclusions: The linear regression formula
derived from PMCT spine length parameters particularly thoracic and lumbar spine gave a finer
correlation with autopsy body length and can be used for accurate estimation of cadaveric height.
To the best of our knowledge, this is the first ever linear regression formula for cadaveric height
assessment using only post mortem CT spine length measurements.

Introduction: Autopsy is one of the most important approaches
to identify clearly the exact cause of death, whether it was due
to natural causes, sudden death, or traumatic. Various studies
have been done in different countries regarding ways to
improve the diagnosis during autopsy. The imaging approach
is one of the methods that has been used to complement
autopsy findings and to enhance the diagnosis for achieving the
most accurate post-mortem diagnosis. The aim of this study is
to identify the role of imaging modalities that complement
routine autopsy and correlate the findings of diagnostic
imaging that can help improve the accuracy of diagnosing the
cause of death.
Methods: We sourced articles from Scopus, Ovid and PubMed
databases for journal publications related to post-mortem
diagnostic imaging. We highlight the most relevant full articles
in English that explain the type of modality that was utilised
and the added value it provided for diagnosing the cause of
death.
Results: Minimally invasive autopsies assisted by imaging
modalities added a great benefit to forensic medicine, and
supported conventional autopsy. In particular the role of post
mortem computed tomography (PMCT), post mortem
computed tomography angiography (PMMR) and positron
emission tomography computed tomography (PMCTA) that
have incremental benefits in diagnosing traumatic death,
fractures, tissue injuries, as well as the assessment of body
height or weight for corpse identification.
Conclusion: PMCT and PMMR, with particular emphasis on
PMCTA, can provide higher accuracy than the other
modalities. They can be regarded as indispensable methods
that should be applied to the routine autopsy protocol, thus
improving the findings and accuracy of diagnosing the cause of
death.
