Application prospect of radiomics in forensic examination on bone and joint injury / 中国法医学杂志

In recent years,radiomics has been developed rapidly in the field of clinical medicine,and the artificial intelligence(AI)technology has been utilized to assist diagnosis.This paper introduced the background of radiomics,analyzed the basic research process of radiomics,and looked forward to its application in the identification of bone and joint injuries in the field of forensic medicine.Reviewing the three aspects is expected to provide a theoretical foundation of radiomics,which will be helpful to develop its application in forensic medicine.

Application of thin-section computed tomographic images in measurement of safe range from foramen rotundum to siphon of internal carotid artery for operation through pterygopalatine fossa / 吉林大学学报(医学版)

Objective:To measure the safe range from the foramen rotundum to the siphon of internal carotid artery using three-dimensional reconstruction technique, and to provide guidance for operation through pterygopalatine fossa.Methods:The skulls of 121 volunteers were scanned to get the final results with thin-section computed tomographic images.The position of the siphon of internal carotid artery (point A)and foramen rotundum (pointB)were ascertained.Three-dimensional reconstruction technique was used to build a coordinate system paralleled to the frankfort horizontal plane and the nasal septum plane.The coordinate system took point A as the coordinate origin.Point C and point D were the projections of point A in two planes parallel with frankfort horizontal plane and nasal septum plane which included point B.The distances of AC,AB,and BC were measured. The angles of the line went through A and B to the three planes were also measured.Results:The distance of AC was measured as 13.22 (3.79)mm (range,8.33 - 105.67 mm;95%CI:8.55 - 21.39 mm).The angle to the sagittal plane was measured as 33.54 (9.23)° (range,5.38- 66.58°;95%CI:30.88 - 34.20°). The angle to the coronal plane was measured as 53.17 (10.48)°(range,5.60-75.02°;95%CI:51.29-55.06°).The angle to the horizontal plane was measured as 9.43 (12.91 ) mm (range,- 28.44 - 82.22;95% CI:7.11 - 11.76 ). Conclusion:The safety distance from foramen rotundum to the siphon of internal carotid artery in the operation through pterygopalatine fossa (PPF) under nasoendoscope is obtained by thin-section computed tomographic images.
