Abstract:
Objective: To quantitatively study the morphological structure and parameter of right atrial appendage (RAA) by 256-slice spiral CT to provide RAA imaging reference for interventional or surgical therapy in clinical practice. Methods: A total of 200 patients with negative CTA results examined in our hospital were studied including 96 male and 104 female; by age division, Age≤40 years group,n=29, Age (40-60) years group,n=114 and Age>60 years group,n=57. The original scanning data was reconstructed for RAA establishment, indexes of volume, radial lines were measured and compared between different gender and age groups to obtain 95% normal imaging references of RAA. Results:①The volume, height, basilar part circumference, anteroposterior spread of RAA in male were greater than female, allP<0.05; with surface area standardization, the long and short diameter of basilar part, area, circumference in female were greater than male, allP<0.05.②Anteroposterior angle and spread of RAA in Age<40 years group were higher than both Age (40-60) years group and Age>60 years group,P<0.05, the above parameters were similar between Age (40-60) years group and Age>60 years group,P>0.05.③95% normal reference ranges of RAA were as following: volume (4.83-19.97) ml, height (21.46-41.80) mm; basilar part longest diameter (25.89-41.65) mm, short diameter (19.34-36.24) mm, area (459.30-1093.28) mm2, circumference (86.16-147.04) mm; anteroposterior angle (1.67-31.23) °, spread (8.07-34.37) mm. Conclusion: 256-slice CT may quantitatively study the morphological structure and parameter of RAA and establish its 95% normal imaging references for clinical practice.
