The use of Medical Imaging Technology in Forensic Science is long acknowledged. A sex estimation method based on digital radiographs of the radius is proposed here. l Univariate and multivariate discriminant functions are generated resulting in up to 88% accuracy for a contemporary Greek population. l This a rapid, easy and inexpensive method for sex screening of forearm fragments based on digital radiographs of the radius recommended for fragmentary commingled situations.

“…Last, an osteometric study on the radius in the same Cretan population resulted in 86.1% accuracy for the radial head diameter and only 80% accuracy for the distal radius breadth. The combination of both variables did not seem to improve classification accuracy significantly (86.7%) [49].…”

“…Discriminant functions address single variables or combinations of them and they base the selection on the F-values. The F-value for a variable indicates its statistical significance in the discrimination between groups, that is, it is a measure of the extent to which a variable makes a unique contribution to the prediction of group membership [26]. In most of these studies however no information on the reliability of the predictions is given.…”

“…The purpose of this study is to develop a sex estimation method based on classical osteometric dimensions of the upper limb bones, with the aid of the Receiver Operator Characteristics (ROC) Analysis, a technique basically used so far on medical decision making. The study will be carried out using a sample of modern Greeks from the island of Crete [25,26].…”

Discriminant function analysis is one of the most popular methods employed for grouping specimens according to optimal combination of linear measurements. Many studies have used this method with the objective of producing population specific formulae for sex estimation from different skeletal parts of the skeleton. This study focuses on the long bones of the upper limb using Receiving operation characteristics (ROC) curves. A total of 173 well preserved skeletons of Cretan origin were used. A total of 12 measurements are taken from the bones of the upper limn. The diagnostic value of the single variables was evaluated using the Area Under the Curve (AUC). The cut-off values and the diagnostic characteristics of each variable (Sensitivity, Specificity, Positive and Negative predictive values) are presented. The correlation of normally distributed the variables will be tested with the method Pearson correlation coefficient. The level of statistical significance is set to p<0.05 (a-error). Means, standard deviations and F-ratios for all single dimensions are calculated by performing ANOVA with SPSS 13.0.All measurements are found statistically significant at the level of 0.0001. The best discriminatory variables was found to be radius length (91.3%) followed by humerus head vertical diameter (90.2%) and ulnar length (89%). Comparison with published standards for mainland Greece reaffirms a scope for developing additional standards for modern Cretans. Traditional methods use discriminant function analysis to study sexual dimorphism. Herein a different approach is proposed. ROC curves, known to be very effective in medical decision making, are employed in the evaluation of several variables as effective markers for sex identification. The method should complement multivariate statistical analyses.

Documented skeletal collections constitute a key resource in forensic anthropological and bioarchaeological research as they allow both the development of methods for the estimation of various parameters of an individual's biological profile, and the examination of the accuracy of existing methods in different skeletal assemblages. The acknowledgement of the utility of documented collections is attested by the large number of such collections across the world. The current review will focus on two modern reference collections in Greece, briefly presenting their composition, the research projects in which they have been employed, and future prospects for their use.
