Abstract :Objectives: The ratio of the diameter of pulmonary trunk insert ignore into journalissuearticles values(PT); to the diameter of the ascending aorta insert ignore into journalissuearticles values(AA); is used to evaluate cardiopulmonary diseases. Different values have been reported for the normal value of PT:AA ratio insert ignore into journalissuearticles values(to be less than 0.9, 1 or 1.4);. In this study, we aimed to investigate the diameters of the PT, right insert ignore into journalissuearticles values(RPA); and left pulmonary artery insert ignore into journalissuearticles values(LPA);, AA, right insert ignore into journalissuearticles values(RMB); and left main bronchus LMB); using multidetector computed tomography insert ignore into journalissuearticles values(MDCT); and to determine reference values for PT:AA according to age and sex in normal healthy adults. Methods: Thoracic CT images of 200 individuals, insert ignore into journalissuearticles values(103 males, 97 females; age 18–89 years);, without cardiopulmonary pathology and surgery, were retrospectively evaluated using MDCT. Diameters of PT, RPA, LPA, AA were measured at the level of the pulmonary artery bifurcationand PT:AA ratio was calculated. Results: The mean diameters of PT, AA, RPA, LPA, RMB, LMB were found as 2.7±0.51 cm, 3.25±0.63 cm, 1.98±0.46 cm, 1.81±0.43 cm, 1.73±0.35 cm, and 1.66±0.55 cm, respectively. The mean value of PT:AA ratio was 0.84±0.18 cm in males and 0.86±0.13 cm in females. Conclusion: Determining the normal values of related measurements will contribute to diagnosis and treatment of cardiopulmonary diseases.
