Abstract:

Objective     To observe and measure the angle of the uncinate process in different ages and different genders on the enhanced MDCT images so that the normal range of the angle of the uncinate process could be determined, which could provide data for the diagnosis of occupying lesion of the pancreatic head.   Method    Retrospective analysis was carried out for 612 cases of patients without obvious abdominal diseases with the age older than 20 years. the patients were divided into 6 groups (21～30 years, 31～40 years, 41~50 years, 51~60 years, 61~70 years and above 71 years) and 2 groups by gender(male and female).  The max angle of the Uncinate process was measured after enhanced CT image reconstruction with a collimation of 3 mm, and analysis the data was performed by SPSS software.   Result    The angles of different groups were as follows:（34.7±5.4）°, （56.3±4.8）°, （64.1±5.1）°, （57.8±3.3）°, （47.4±4.1）°and （33.5±3.9）° respectively in the 6 groups, and（54±2.7）° in female、（61±3.5）° in male.   Conclusion    The angle of the uncinate process increased younger than 60 years old, and then decreased. We also learn that the angle of the uncinate process is larger in male than in female.
