Unlike helical scan modes which provide images of the entire width of the chest, modern scanners with large volume detectors and prospective gating may reduce the field of view (FOV) to only 25 cm around the heart. The imaged portion of non-cardiac structures such as the lungs is therefore less than with conventional scan techniques. We aimed to assess the prevalence of significant non-cardiac findings in patients undergoing CTCA for evaluation of coronary artery disease. Method: CTCA performed from 05/12/12 to 01/03/13 were reviewed by a radiologist to detect non-cardiac abnormalities. Scans with an extended FOV were excluded (bypass grafts, aortograms and helical scan modes).Results: 222 CTCAs were performed in this period. Forty-two cases were excluded (helical scans, graft studies and aortograms). One hundred and eighty consecutive patients scanned using a prospective, 25 cm FOV protocol were included. No extra-cardiac findings were reported in 124 (68.9%) patients. Abnormalities detected were as follows: 22 (12.2%) minor lung atelectasis, three small pulmonary nodules, one pulmonary cyst, two pulmonary bullae, one severe emphysema, one lymphadenopathy, one thickened pleura, one pleural plaque, eight (4.4%) hiatus hernia, 10 (5.6%) liver lesions, four pectus excavatum, two breast prosthesis, two degenerative spine and one diverticulum at the splenic flexure.Conclusion: Incidental non-cardiac findings are not uncommon (∼30%) even with reduced FOV broad detector prospective CTCA. http://dx.
Conclusion:This was the first follow-up study of its kind in Timor-Leste, observing the course of echocardiographydetected RHD in a cohort with excellent adherence to secondary prophylaxis. Disease progression was rare, emphasizing the value and potential impact of a successful program of follow up and secondary prophylaxis in similar settings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
