Aim: We aimed to evaluate the consistency of the measurements of diameter and area of cardiac chambers in coronary computed tomography angiography (CTA) and contrast-enhanced thoracic computed tomography (CT) images. Materials and Methods: 30 patients who underwent thoracic CT and coronary CTA over a 6-month period between August 2016 and August 2019 were included in the study. Maximum left atrium area, anteroposterior and transverse left atrium diameter, right atrium transverse diameter, right and left ventricular transverse diameters were measured by two observers. Inter-observer and intra-observer Contrast-enhanced thoracic CT and coronary CTA measurements of the cardiac chambers were found to be perfectly compatible. Both left atrial axial area and AP diameter were evaluated on coronary CTA images and contrast-enhanced thoracic CT with excellent reproducibility. Conclusion: To our knowledge, this is the first study that shows the measurement of diameter and area of the cardiac chambers in thoracic CT and coronary CTA and comparing them with each other. Thoracic CT, with its high reproducibility, could be a useful tool in evaluation of cardiac chambers.
