Computed tomographic studies on ossification status of medial epiphysis of clavicle: Effect of slice thickness and dose distribution.

The accuracy of technique adopted for Forensic age diagnostics of young adults and adolescents especially in case of livings lies in the standardization of the technical parameters used. The emerging radiological techniques, when used in standardized way may minimize the possibilities of misinterpretation, as it has been practically shown in present study. CT scans of 100 live subjects were performed on 16-slice (Siemen’s Sensation 16) CT scan machine and the volumetric data acquired was reconstructed into five separate sets of slice thickness for each one of the subjects included in the study and the ossification status for each set of slice thickness was determined for all the subjects separately. The results are almost identical while evaluating ossification stages from 1 and 2 mm thick slice data but the differences are found in the ossification stages when evaluated using 3 mm, 5 mm and 7 mm slice thickness as compared those found in 1 and 2 mm slice thickness. It was concluded that by increasing slice thickness the rate of error-nous interpretation are also increasing. Thus, the minimum reliable thickness to produce high resolution scans in order to get maximum accuracy is 2 mm for staging medial clavicular ossification from CT scan and the reconstruction should be done using kernel (filter) B60F at window setting osteo (1500/450HU).

Revenge by the bites.

Bite marks are important evidences, which are most often ignored by the investigating officers in India. Sometimes due to lack of this knowledge, let the culprit go Scot-free. Bite marks help to link the culprit with the crime. It is important scientific evidence, which if properly collected and analyzed can help, in successful prosecution of the case. Analysis of a case of bite marks is presented here by which culprit could be identified.

Estimation of stature from hand and phalange length.

Personal identification is an integral part of the investigation in cases of mass disasters where disintegrated and amputated body organs are found very frequently. Plastic and latent fingerprints and palm prints are also available very commonly at most of the scene of crime. Estimating stature from various parameters based on the above mentioned evidences becomes one of the most important and essential exercise for personal identification .In present paper, study on stature estimation from hand and phalanges length has been reported. Stature and phalanges length of all the fingers of both the hands of 60 individuals have been measured. The inked palm prints were also obtained and the same measurements were recorded from it also. The regression equations have been drawn from the data collected. It has been observed that stature can be estimated from the phalangeal lengths.
