- “Inter-observer agreement between the study reviewers was moderate to good (0.4–0.73) for most of the incidental cardiovascular findings. At least one incidental cardiovascular finding not documented in the original report was identified by the study reviewers in 225/409 (55 %) of chest CT examinations. A total of 168/266 (63.2 %) potentially clinically significant cardiovascular findings were unreported in the original reports of 177/447 (39.6 %) subjects (p < 0.0001). Senior radiologists tended to more frequently report coronary artery calcification (p = 0.0006), cardiac valves calcification (p = 0.0003), and ascending aorta enlargement (p = 0.01) compared to junior radiologists.”
Under‐reporting of cardiovascular findings on chest CT Nicola Sverzellati et al. Radiol med (2016) 121:190–199 - “In keeping with our study, local radiologists only seldom specified which coronary artery was calcified. However, it was shown that visually scoring CAC on ungated CT is feasi- ble and of prognostic value. We could not stratify the prognostic value of CAC in our study cohort as the study observers applied a different CAC classification system.”

- 24 patients with cardiac findings (ventricular pseudoaneurysm, ventricular perfusion defect, intracardiac thrombus)
- 34 patients had a noncardiac finding PE, lung cancer, pneumonia)
- 17 patients had at least one graft occluded "In the immediate postoperative period 51 patients (19.7%) had at least one unsuspected potential significant finding."

Mueller J et al.
AJR 2007; 189:414-419"Cardiac CTA after CABG revealed a high prevalence of unsuspected cardiac and noncardiac findings with potential clinical significance. Interpreters of these studies should be familiar with the spectrum of these abnormalities."
Cardiac CT Angiography After Coronary Bypass Surgery: Prevalence of Incidental Findings
Mueller J et al.
AJR 2007; 189:414-419- "Volume analysis revealed that 35.5% of the total chest volume was displayed on dedicated coronary artery MDCT focused on the heart, whereas 70.3% of the chest was visible when MDCT raw data were reconstructed with the maximal field of view."
