“…Reports suggest that incidental extracardiac findings (ECF) can be detected on cardiac CT studies in 15-90% of cases [2][3][4][5][6][7][8][9][10][11][12]. While the vast majority of these will turn out to be benign, pathologically important findings have been reported in 4.2-38% of cases [2][3][4][5][6][7][8][9][10][11][12]. These studies have generally focused on a single examination (calcium scoring, coronary CTA, CABG evaluation, etc.…”

To investigate incidental extra-cardiac findings (ECF) at cardiac CT based on indication and impact on patient management. We retrospectively reviewed the reports of 1,764 patients who underwent a cardiac CT study between January 1, 2004 and December 31, 2006, including 463 calcium scorings (CS), 737 coronary CT angiograms (CTA), 341 pulmonary vein stenoses (PVS), and 223 bypass grafts (CABG). ECFs were categorized by type of examination, anatomical location and clinical significance. Comparisons were made between examination types to determine if incidental findings varied by indication. There were 507 ECFs with at least one ECF in 441 patients (25.0%). By examination, there was at least 1 ECF in 79/463 CS studies (17.1%), 196/737 CTAs (26.6%), 80/341 PVSs (23.4%) and 86/223 CABGs (38.6%). In 325 patients (18.4%), the findings were considered clinically important and occurred in 60/463 (12.9%) CSs, 149/737 (20.2%) CTAs, 56/341 (16.4%) PVSs and 60/223 (26.9%) CABGs. Differences between CABG and other indications and CTA vs. CS for incidental and clinically important findings were statistically significant (p < 0.05). Extra-cardiac findings requiring follow-up occur in 18% of patients and are significantly more frequent in coronary artery CTA and coronary artery bypass studies than in calcium scoring studies.

Aim To investigate non-coronary findings during coronary calcium scoring with computed tomography. Material and Method190 patients who were evaluated with multislice computed tomography for coronary calcium scoring, were included in the study. Noncoronary findings were described as Minor and Major A-B findings.Results One hundred seventy seven non-coronary findings were found at 80 (42.1%) patients. There were minor findings at 40 (21%) and major findings at 40 (21%) of the patients. There were 13 Major B findings including aortic aneurysm, pulmonary mass, pulmonary nodules, infiltrates, pneumonectomy, surrenal nodular thickening and liver mass lesions.Conclusion Non-coronary findings are frequent, and radiologist and/or cardiologist who has been reporting these findings should be aware of the frequency and importance of these findings.

The incidental detection of thyroid lesions in patients undergoing magnetic resonance (MR) imaging of the cervical spine was prospectively evaluated on 389 MR images. Sagittal images extended from the cranio-cervical junction to the upper thoracic level, and axial images from C3-4 to C7-T1 intervertebral levels. Twenty patients (5.1%) had a total of 26 thyroid nodules. Eighteen patients presented with a single dominant nodule, of whom 2 had a multinodular gland with a single dominant nodule (one had 3 and the other had 5 nodules). Two patients had diffusely enlarged gland without a dominant nodule. The mean size of the nodules was 11.6 mm. One thyroid nodule was detected at the C5-6 intervertebral level, 14 at the C6-7, and 11 at the C7-T1. T 2 -weighted imaging was more useful than T 1 -weighted imaging for the detection of thyroid nodules because of the hyperintense versus isointense appearance of the lesions. Thyroid carcinoma was identified at surgery in one patient. The detection rate was low compared with computed tomography with contrast medium and ultrasonography. Our results suggest that MR imaging has limited value for the detection of thyroid lesions and that the presence of such lesions cannot be denied based only on MR imaging of the cervical spine. However, asymptomatic thyroid lesions, including thyroid cancer, can be identified on MR images of the cervical spine, so we recommend that evaluation of these images should consider such lesions.
