Objectives: The aim of the study was to reveal the mean values of the cardiothoracic ratio (CTR) and the effect of gender and age on these measurements performed on chest radiographies. Methods: After the exclusion of positive findings on radiographic images and the findings compatible with cardiovascular disease, the radiographies of 277 patients were re-evaluated regarding CTR measurements on chest X-rays. The maximum interval of the right and left heart borders, along with the horizontal thoracic diameter, were measured. Results: The mean values of CTR were 0.45+/-0.02, 0.46+/-0.02 and 0.44+/-0.02 for the total study population, for the female group, and the male group respectively. Higher CTR was measured for females than for males (p<0.001). Age indicated a low but significant positive correlation with the CTR for the total study population (p<0.001). Conclusion: Chest X-ray is a fast and inexpensive imaging method; performing CTR measurements is very easy to apply on chest X-rays. CTR still serves as a significant indicator of cardiovascular diseases along with other important parameters observed in chest radiographs.
