| Summary: | Purpose: The purpose of this study was to emphasize the value of calcium scoring (Ca score) using a large field of view (“large FOV”) as a screening method for detection of extracardiac incidental findings.
Materials and methods: 64-Multislice CT angiography using a “large FOV” in the preliminary calcium score followed by the post-contrast routine “small FOV” examination was performed for 382 consecutive patients between January 2011 and December 2012.
Results: 375 Patients (203 men and 172 women) with age range between 40 and 80 years (mean, 60 years), were studied, using a “large FOV” technique. Among whole incidental extracardiac findings, “significant” extracardiac abnormalities (emergent and intermediate findings) were detected in 24.8% of cases, among which 13.6% would have been missed if only using a “small FOV” technique.
Conclusion: Results showed that using Ca score with a “large FOV” is favorable for better, accurate and more frequent detection of extracardiac incidental findings. With usage of low dose technique, the difference in dose between “small FOV” and “large FOV” techniques is justified for detection of supplementary “significant” extra-cardiac findings including serious findings such as lung cancer or metastatic deposits.
