Background: Cardiothoracic ratio (CTR) is an easy and cheap diagnostic tool in the estimation of the cardiac sizes which is used for the screening and diagnosis of cardiac diseases. Objectives: The study objectives were to assess the normal cardiac size in apparently healthy adults and establish reference ranges in our population for comparison when investigating cardiac diseases. Materials and Methods: Radiographic evaluations of the cardiac size were performed from March 2017 to February 2018 in 172 apparently healthy individuals who were referred to the Radiology Department, Federal Neuro-Psychiatric Hospital, Maiduguri, in Nigeria, for medical examinations. The individuals were divided into the following five age groups: 18–27, 28–37, 38–47, 48–57 and 58 years and above, in order to determine the influence of age on cardiac size. Results: The mean CTR for males and females was 45.10% and 45.71%, respectively, and was statistically insignificant (0.362). The mean CTR of the general population was 45.6%, and the mean CTR value increased with age until the fourth decade when it reduces with age. Conclusion: The result of this study has established the CTR of the Nigerian population in Maiduguri. The CTR gradually increased with age until the fourth decade when it reduces with age. Therefore, establishing normal ranges of CTR is necessary for comparison in a condition where a possible cardiac disease is being examined.
