“…Image data were processed on a workstation (Synapse Vincent, Fujifilm Medical, Tokyo, Japan) to obtain orthogonal multiplanar reconstruction images and volume rendering technique images. Reconstructed cross-sectional images were viewed using a window width of 1,600 HU and a window level of 1,000 HU as described previously [8]. …”

“…These images were each categorized by visual evaluation into one of seven stages according to the degree of closure as defined by Harth et al (Fig. 2; Table 1) [8]. All images were evaluated by a single assessor, and intra- and inter-observer reproducibility was tested by randomly selecting 30 subjects for reevaluation by both the original and a second assessor.…”

“…Cranial suture closure progresses with age, and therefore, the macroscopic assessment of the surface of cranial sutures has long been used as a method of age estimation [14–17]. Some reports suggest that cranial suture-based age estimation should be avoided because the degree of closure of cranial sutures demonstrates large individual differences [8–20]. However, thus far, no definitive method of age estimation has been established, and cranial suture evaluation remains essential in this field of forensics, especially when the skull is the sole remain.…”

“…Harth et al scanned cranial bones with CT and assessed the cross section of sutures; however, this study was performed using flat-panel CT and cranial bones from which the soft tissue had been removed [8, 9]. Flat-panel CT is superior to multidetector CT (MDCT) in terms of spatial resolution and is considered suitable for the evaluation of sutures.…”

Closure of cranial sutures progresses with age; therefore, macroscopic assessment of cranial sutures has been used as one method of age estimation. Postmortem computed tomography (PMCT), which many forensic medical departments and institutes have begun to adopt, has the potential to simplify the gathering of information from cranial sutures for both surface and cross-sectional evaluation. To examine the feasibility of age estimation by cross-sectional multidetector computed tomography images of the sagittal suture, PMCT findings of 125 subjects of known age and sex were retrospectively reviewed. The sagittal suture was divided into four segments, and 20 cross-sectional slices from each segment were analyzed. These slices were each categorized by visual evaluation into one of the seven stages defined by Harth et al. according to the degree of closure. The mean stage value of 20 slices was calculated for each segment. We were able to evaluate cross-sectional images of the sagittal suture by PMCT, and a positive correlation between age and closure degree was observed. Despite the prediction interval achieved with this method not being superior to traditional macroscopic or flat-panel CT assessment, multidetector CT is a potentially useful tool, in conjunction with other methods, for age estimation, particularly in adult females and in cases where only a skull is the sole remain.

“…Further, with the advancements in the forensic anthropology field and the need to continuously improvise and validate methods, the conventional approach for age estimation in adults may be challenged. Advancements like radiographs, computed tomography and magnetic resonance imaging are already being utilized as complementary source of data [49]. The researchers are now confronted with development of new population specific standards using the recent advancements for age estimation.…”

Reconstruction of biological profile of unknown individuals would be incomplete without age determination. Forensic anthropologists use skeletal indicators involved in processes of bone resorption, deposition and remodelling which are time-related to estimate age of the individual. Estimating age in adults remains a challenging task to the forensic anthropologists because of the complexity and individual variations seen in the aging process and the gamut of environmental factors influencing the same. Age provided by anthropologists is determined as age range rather than a specific age. It has been noticed that age range determined for younger individuals is narrower than for older individuals. This paper reviews most commonly used skeletal age estimation methods by forensic anthropologists.
