Multi-detector computed tomography for assessment the correlation between dimensions of hepatic vessels and factors of aging, gender and anatomy variants
Main Article Content
Abstract
SUMMARY
Objective: The study aimed to determine the correlation between dimensions of hepatic vessels (including hepatic arteries, portal and hepatic veins) and aging, gender and anatomical variants factors, using multidetector computed tomography (MDCT).
Design: We conducted a retrospective study of 611 adults (344 Male, 277 Female, mean age 55.0 ± 13.1 years), who were clinically examined and underwent abdominal MDCT with iodinated contrast agents for different complaints at the University Medical Center between August 2017 and August 2018. MDCT images were stored on the picture archiving and communication system (PACS) and processed to create multiplanar reformation (MPR), curved planar reformation (CPR), maximum intensity projection (MIP), volume rendering (VR) images which were subsequently used to measure the length and diameter of hepatic arteries, portal, and hepatic veins. Also to determine the correlation between dimensions of hepatic vessels and aging, gender and anatomical variants factors.
Results: The average diameter of common hepatic artery in the variant group was smaller than in the normal group. The length of common hepatic artery increased with age (P<0.05). There was a strong correlation (R = 0.77, P <0.05 ) for the diameters between the common hepatic and proper hepatic arteries. The diameters of main portal vein, right portal vein and left portal vein decreased with age (P<0.05). The male group had diameters of hepatic artery and portal vein greater than the female one. There is no correlaton between the dimension of hepatic veins and some factors of anatomy, age and gender.
Conclusions: MDCT might be considered a safe and accurate imaging modality with high sensitivity in assessing the correlation between dimensions of hepatic vessels and the factors of age, gender and anatomical variants.
