Abstract:
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. 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. 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). 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. References 1.

Biography:
Tawfiq Zyoud is doing his PhD at the University Putra Malaysia (UPM) his scientific life journey started in 2012 at Palestine Ahliya University, where he got his Bachelor's Degree in Medical Imaging.. He organized workshops at the UPM Malaysia and participated as a speaker and poster at several international conferences in 2019 he got the Best Poster Award. He got scientific representative of Palestine in the 4th Annual Radiology Meeting in UAE conference. Moreover, in 2021 from ARID Scientific Platform, he earned an Initiative researcher Badge, an Activist at ARID Scientific Events Badge 2021, and an Innovative researcher Badge. Also, he received the Distinguished Researcher Award of the Year by Asia Awards powered by RULA Awards. His plan for the future, after he finishes his PhD is to apply for a post-doctoral program, and in addition to that, he aspires to be famous researcher, especially in the field of forensic medicine.
