2 Heart Disease and Coronary Calcium Coronary artery calcification (CAC) is a very strong predictor of morbidity and mortality in asymptomatic individuals 1 CAC is independently predictive of coronary events over and above traditional cardiac risk factors such as the Framingham Score 2,3,4,5 1 J Am Coll Cardiol 2007;49: J Am Coll Cardiol 2005, 46: Am J Epidemiol 2005, 162: J Am Coll Cardiol 2005;46: Circulation 2003, 107:

4 Ungated Lung Screening CT ECG-gated Calcium Score CT
5 Agatston CAC scores derived from low dose lung CT correlate well with ECG gated CAC CT (Kappa = 0.89) 1 CAC is predictive of death from cardiovascular disease after adjusting for sex, age, pack years of smoking 2 1 Wu MT, et al. AJR Am J Roentgenol 2008;190: Shemesh J, et al. Radiology 2010;257:541-8.
6 CAC is a better predictor of cardiovascular events and all-cause mortality than FEV1 and emphysema extent 1 CAC is an independent predictor of all-cause mortality and cardiovascular events 2 1 Sverzellati N, et al. Radiology 2012;262: Jacobs PC, et al. AJR Am J Roentgenol 2012;198:

18 ECG-gated CACS using 1 mm slices (instead of 2.5 mm) overestimate calcium scores by: +5% in stationary phantoms 1 +30% in patients 1 CAC detection at lung screening CT: 1 Invest Radiol 2005;40: AJR 2008;190:

22 2.5 mm slice thickness
23 1.2 mm slice thickness
24 0.6 mm slice thickness
25 2.5 mm thick CAC protocols may underestimate calcium scores relative to ground truth Chance of missing a 1mm calcified lesion of a given density Slice thickness 800 mg/cm mg/cm mg/cm mm 0% 100% 100% 1.2 mm 0% 86% 100% 0.6 mm 0% 14% 95%
26 The traditional 2.5 and 3.0 mm thick CAC scoring protocols will miss smaller lesions and underestimate disease burden This limitation would affect primarily younger subjects with near zero or lower calcium scores and is encountered in clinical practice

35 Why 2.5 mm slices? 1984: Electron beam CT Temporal resolution = 100ms Spatial resolution = 2-3mm 1995: ECG-gated MDCT Temporal resolution = 160ms Spatial resolution = 1.25mm 2005: Dual Source CT Temporal resolution = 75-83ms Spatial resolution = 0.3mm

37 Detection of small CAC requires thinner slices However image noise increases with thinner slices given a constant radiation dose
38 1mm slices 3mm slices 1 Invest Radiol 2005;40:
39 Lung Screening CT Coronary Calcium CT Radiation dose 0.7 msv (120kV, 15mAs) 0.7 msv (120kV, 50mAs) Scan length Full chest Cardiac only (40% of chest) The dose of CAC CT would have to be reduced by about 60% in order to match the very low dose of lung screening CT (0.7 msv for entire chest).
40 FBP Reconstruction Bone Kernel
41 FBP Reconstruction Soft Tissue Kernel
42 Iterative Reconstruction (100%)
43 Model-based Iterative Reconstruction
44 The maximum variability using iterative reconstruction is 2% in a stationary phantom This is much lower than our observed maximum interscan variability of 24% in a phantom
45 Iterative reconstruction underestimates CAC scores by 6-22% compared to traditional filtered back projection 1 Gebhard C, et al. Int J Cardiol 2012; Sept 5. [epub]
46 r = 0.99 The 0.2 msv CACS CT 100 kv and 80 mas, ECG-gated Employed a threshold of 147 HU (vs. 130 HU) High correlation w/ 120 kv 80 mas scan (r=0.99) 3% of cases were unreadable due to noise Overestimation of CAC scores by about 11 7% had a misclassified risk categorization Marwan M, et al. J Cardiovasc Comput Tomogr 2013; 7:32-38.
47 How much interscan variability is acceptable? Should the gold standard always be 2.5 mm? Can the 130 HU threshold be optimized? How is CACS affected by: Field of view Helical versus axial CT Increased noise (Slice thickness, Dose, Patient Size) Newer noise reduction strategies Other calcium scoring techniques (volume, mass)
48 Combined lung and cardiac CT screening will require the latest technologies to optimize radiation dose and diagnostic accuracy Existing limitations in CAC measurements should be recognized and addressed CT protocols may need to be individually tailored to improve risk stratification The Zena and Michael A.
