Abstract Background Although some studies have reported cardiac diseases in macaques, an adequate screening method for enlargement has not yet been established. This study aimed to evaluate the positioning of macaques radiographs and establish reference intervals cardiothoracic ratio (CTR). Materials Methods We developed a device chest radiography sitting position performed 50 Japanese 48 rhesus CTR cavity size. Results In thorax height was significantly larger, heart width smaller, mean smaller than prone position. The were 51.6 ± 4.6% 52.2 5.1% respectively. Conclusion Thoracic radiographic images obtained resulted larger height, which could be useful detecting pulmonary abnormalities.
