Between 2008 and 2017, a total of 68,656 patients underwent 142,111 chest CT examinations at both hospitals combined. The number of annual chest CT scans increased from 11,315 in 7,861 patients to 18,511 in 12,565 patients during this period, an increase of 64%. The trends in the number of patients and studies are shown in Figure 3 and 4, respectively. The percentage of patients, in whom nodules were reported, increased from 33% (2,605 individuals) in 2008 to 50% (6,253 individuals) in 2017. The proportion of these patients who received a follow-up chest CT increased from 911/2,605 (35%) to 2,792/6,253 (45%). The average number of follow-up scans per patient remained similar (1.58 in 2008; 1.64 in 2017).
