Radiographic anatomy of the heart of fruit bats.

As the only mammal that can fly, bats have organ systems with a unique morphophysiology. One of the highlights is the heart and blood circulation system, which must be able to meet the needs of blood and oxygen supply when flying. This study examined the radiography of the normal condition of the heart organ in 3 species of fruit bats, namely Cynopterus titthaecheilus, Cynopterus brachyotis and Rousettus leschenaultii using radiological silhouette analysis and clock analogy. The results showed that the heart positions of the three bat species tend to be tilted to the left with the apex moving away from the midsagittal plane. Analysis of intercostal space (ICS) value and vertebral heart score (VHS), and evaluation of radiographic features showed R. leschenaultii has a relatively larger heart size than the other two species. All three bat species have a higher VHS than mammals in general. Radiographic images obtained, and interpretation results show the position, size and normal heart parts of the three bat species. They will be useful in diagnostic efforts related to heart problems in these three species.
