In a mass chest computed tomography (CT) screening using a mobile helical CT unit, we measured the aortic diameter at three segments to confirm standard values and also attempted to detect any asymptomatic @entity449 . The population screened in the present study consisted of 6971 subjects (3847 @entity1 and 3124 @entity1 , mean age 60.3 +/- 12.1 years). They underwent a plain chest CT to screen for @entity2 and @entity378 . The diameters of the ascending and descending aorta were measured at the level of the pulmonary artery bifurcation. The abdominal aorta was measured at the level of the celiac bifurcation, and the mean values for each measurement were calculated. In addition, we attempted to determine whether any correlation exists among aortic diameter, age, and indices of body size and investigated the frequency of asymptomatic @entity449 among the general population. The mean aortic diameter of all three segments was significantly larger in @entity1 than in @entity1 and increased with age. It also correlated significantly with indices of body size (P < 0.01). A total of 11 subjects (0.16%) had asymptomatic @entity449 (3 ascending, 4 descending, and 4 thoracoabdominal). The aortic diameter in each individual case was greater than the mean aortic diameter +3 standard deviations in each age group. Chest CT screening for @entity2 can thus detect asymptomatic @entity439 through simultaneous aortic measurement.
