Gender determination from skeletal remains is one of the primary factors in forensic medicine. This study aimed to identify the gender of patients referred to the radiology ward of the Rasoul Akram Hospital of Tehran using anteroposterior pelvic radiography.
A total of 200 patients (100 male and 100 female) referred to the radiology ward of the Rasoul Akram Hospital for anteroposterior pelvic radiography during 2013-2014 were included in this study. After taking a standard radiographic image of all patients in the supine position and an anteroposterior view of the pelvis, factors including subpubic angles, pubic angle, X angle, ischiopubic index, ratio of the length of the symphysis pubis to the mid and minimum width of the pubis body, and ratio of the length of the symphysis pubis to the minimum width of the pubic superior ramus were measured on radiographs. The Student t test and receiver operating characteristic curve were used to compare the data of male and female patients. Values were significant at p<0.05.
All the evaluated variables were significantly different in male and female patients (p=0.000), with the highest level of measurement accuracy noted in the subpubic angle, Pubic Angle 1, X angle, Pubic Angle 2, minimum width of the pubic superior ramus, and ischiopubic index. Length of the symphysis pubis, length of the pubis, and ratio of the length of the pubis to the minimum width of the pubic superior ramus showed the lowest accuracy.
The results of this study revealed that the evaluation of the radiographic images of pelvic bones by assessing the mentioned factors can be useful for sex determination from skeletal remains. However, ethical considerations should also be taken into account while using these factors.
从骨骼遗骸确定性别是法医学的主要因素之一。本研究旨在通过前后位骨盆X线摄影确定转诊至德黑兰拉苏勒·阿克兰医院放射科病房的患者的性别。
本研究纳入了2013年至2014年期间转诊至拉苏勒·阿克兰医院放射科病房进行前后位骨盆X线摄影的200例患者(100例男性和100例女性)。在所有患者仰卧位拍摄标准X线图像并获得骨盆前后位视图后,在X线片上测量包括耻骨下角、耻骨角、X角、耻骨坐骨指数、耻骨联合长度与耻骨体中部及最小宽度的比值以及耻骨联合长度与耻骨上支最小宽度的比值等因素。采用学生t检验和受试者工作特征曲线比较男性和女性患者的数据。p<0.05时差异具有统计学意义。
所有评估变量在男性和女性患者中均有显著差异(p = 0.000),其中耻骨下角、耻骨角1、X角、耻骨角2、耻骨上支最小宽度和耻骨坐骨指数的测量准确性最高。耻骨联合长度、耻骨长度以及耻骨长度与耻骨上支最小宽度的比值的准确性最低。
本研究结果表明,通过评估上述因素来评价骨盆骨的X线图像有助于从骨骼遗骸确定性别。然而,在使用这些因素时也应考虑伦理因素。
