【摘要】： 【研究背景及目的】根據(jù)國際刑警組織《遇難者識(shí)別指南》，對(duì)遇難者的能夠用于比較的一切數(shù)據(jù)都應(yīng)該得到重視。對(duì)于那些能收集到生前CT片的遇難者，結(jié)合死后CT片的比對(duì)來進(jìn)行同一認(rèn)定，是進(jìn)行個(gè)人識(shí)別的一種重要方法。以往有很多對(duì)頭顱X片測(cè)量進(jìn)行個(gè)人識(shí)別的研究，但由于X線影像有一定程度的放大，其結(jié)果準(zhǔn)確性差，而CT片卻可以準(zhǔn)確的測(cè)量，可以獲得準(zhǔn)確的結(jié)果，所以通過比較CT片進(jìn)行個(gè)人識(shí)別是一個(gè)比較好的方法．本研究是通過對(duì)頭顱CT的數(shù)據(jù)測(cè)量(包括額竇、篩竇、蝶竇等部位)，探尋頭顱CT片多元識(shí)別指標(biāo)與方法，以運(yùn)用于法醫(yī)學(xué)實(shí)踐。 【方法】按照納入標(biāo)準(zhǔn)收集頭顱CT片，測(cè)量本次研究設(shè)計(jì)頭顱CT各項(xiàng)指標(biāo)。用二分類logistic回歸分析指標(biāo)進(jìn)行性別判定情況。計(jì)算相同檢查者不同次頭顱CT片的各項(xiàng)測(cè)量指標(biāo)差值，再計(jì)算不同檢查者相同測(cè)量指標(biāo)間的差值，運(yùn)用二分類logistic回歸分析各項(xiàng)指標(biāo)差值進(jìn)行頭顱CT片同一認(rèn)定。 【結(jié)果】(1)運(yùn)用顴弓間距指標(biāo)進(jìn)行性別識(shí)別正確率較高，達(dá)87％。而其余各指標(biāo)進(jìn)行性別識(shí)別準(zhǔn)確率不高，綜合利用顴弓間距、蝶竇長(zhǎng)徑、前床突間距、前床突顱內(nèi)寬徑和篩板長(zhǎng)度進(jìn)行性別識(shí)別，準(zhǔn)確率可以達(dá)到90％以上。(2)建立頭顱性別判定方程2個(gè)。(3)運(yùn)用額竇寬徑指標(biāo)進(jìn)行同一認(rèn)定正確率最高，達(dá)93．5％，效果最好；其余各項(xiàng)指標(biāo)：顴弓間距、乙狀竇間距、蝶竇寬徑、眼框間距和前床突顱內(nèi)寬徑應(yīng)用在頭顱CT同一認(rèn)定準(zhǔn)確率也在80％以上，有實(shí)踐價(jià)值。(4)建立頭顱CT同一認(rèn)定方程46個(gè)。 【結(jié)論】(1)運(yùn)用頭顱CT片可以進(jìn)行有效的性別判定，，并建立頭顱性別識(shí)別方程2個(gè)。(2)運(yùn)用頭顱CT片可以進(jìn)行有效的個(gè)體同一認(rèn)定，并建立頭顱CT同一認(rèn)定方程共46個(gè)。
[Abstract]:[background and purpose] according to Interpol's Guide to the Identification of victims, all data that can be used to compare victims should be valued. It is an important method of personal identification for those who can collect pre-mortem CT films and compare postmortem CT films for the same identification. In the past, there were many studies on personal recognition of skull X-ray measurement, but because of the magnification of X-ray images to a certain extent, the accuracy of the results is poor, but the CT film can accurately measure and obtain the accurate results. Therefore, it is a better method to identify individuals by comparing CT films. This study is to explore the multiple identification indexes and methods of skull CT films by measuring the CT data (including frontal sinus, ethmoid sinus, sphenoid sinus, etc.). To apply to forensic practice. [methods] CT films were collected according to inclusion criteria, and the indexes of CT were measured. The gender was determined by binary logistic regression analysis. The difference of each measurement index of different head CT films of the same examiners was calculated, and the difference of the same measurement indexes of different examination subjects was calculated. The difference of each index was analyzed by logistic regression analysis of two categories to confirm the same index of the skull CT film. [results] (1) the correct rate of sex identification was 87% by using zygomatic arch spacing index. However, the sex identification accuracy of other indexes was not high. Sex identification was carried out by using zygomatic arch spacing, sphenoid sinus length diameter, anterior clinoid process spacing, cranial wide diameter and ethmoidal plate length of anterior bed process. The accuracy rate could be more than 90%. (2) two head sex determination equations were established. (3) the highest accuracy rate of 93.5% was achieved by using frontal sinus width and diameter index, and the best effect was achieved. Other indexes: zygomatic arch spacing, sigmoid sinus spacing, sphenoid sinus wide diameter, eye frame space and anterior bed process skull width diameter were also more than 80% accurate in the same identification of head CT. It has practical value. (4) 46 identified equations of skull CT were established. [conclusion] (1) effective sex determination can be carried out by using skull CT film, and two brain sex identification equations can be established. (2) effective individual identity can be determined by using skull CT film. A total of 46 identified equations of skull CT were established.
