Extra-Coronary Calcium

摘要: aortic arch as detected by chest radiograph to be 10.6% for elderly men and 15.6% women [2]. This study included 139,849 individuals therefore would appear a good approximation of random sample from the United States population. In relatively large, populationbased Netherlands, prevalence abdominal calcification was 34.8% 58.3% [6]. The Framingham Study reported similar findings, with 57% 47% in ages 60 69 years [7]. ability detect radiography (fluoroscopy) is lower than that CT. Therefore, CT-measured expected higher (Table 8.1). Allison et al. performed whole-body EBT scanning 650 asymptomatic [8]. mean age group 57 53% male. For aged 50 years, descending aorta 29% 29%, respectively. increased 98% 96% above 70 years. 55% 50%, As aorta, also age, occurring 93% Kuller evaluated 169 58 participating Healthy Women [9]. imaged root iliac bifurcation; however, investigators did not characterize exact location but referred any calcium within ascending, descending, or “aortic” calcification. By this general definition, present 71% group. Reaven Sacks 309 patients type 2 diabetes mellitus suboptimal glycemic control, defined HgA1C > 7.5% [11]. Calcification 14%. Raggi 245 self-referred coronary found 37% (ascending, aorta)
