Abstract

Respiratory disease is common in psittacine birds; thus, having evidence-based methods to evaluate clinical cases is important for confirming a diagnosis. The purpose of this study was to describe the computed tomographic characteristics of the normal lung parenchyma of wild blue and yellow macaws (Ara ararauna), including measuring lung volume and normal radiographic attenuation of the lung parenchyma. Ten blue and yellow macaws from a wildlife center were used for this study. For computed tomography, transverse 1-mm slices were obtained, as well as multiplanar and 3-dimensional reconstructions for description of tomographic anatomy. Quantitative lung radiodensity was evaluated by regions of interest and via the histogram method. The lungs occupied the dorsal region of the coelomic cavity, with a triangular appearance on sagittal view, and were divided into left and right lungs. The lungs showed no lobulation. Mean attenuation values obtained were -727.19 ± 44.53 Hounsfield units by the histogram method and -722.19 ± 29.69 Hounsfield units by regions of interest. There was no significant difference (P > 0.05) between methods. Mean lung volume was 26 ± 6.03 cm3. The description of the normal computed tomography lung anatomy and density values of blue and yellow macaws are useful baseline data that can be applied to the diagnosis of respiratory diseases in this species.

蓝、黄金刚鹦鹉正常肺的计算机层析成像特征。
呼吸道疾病在鹦鹉中很常见;因此,采用循证方法评估临床病例对于确认诊断非常重要。本研究的目的是描述野生蓝黄金刚鹦鹉(Ara ararauna)正常肺实质的计算机断层特征,包括测量肺体积和肺实质的正常放射学衰减。这项研究使用了野生动物中心的10只蓝黄金刚鹦鹉。对于计算机断层扫描,获得横向1毫米切片,以及多平面和三维重建,以描述断层解剖结构。定量肺放射密度通过感兴趣区域和直方图法进行评估。肺位于体腔背侧,矢状面呈三角形,分为左右肺。肺未见分叶。直方图法得到的平均衰减值为-727.19±44.53 Hounsfield单位,感兴趣区域得到的衰减值为-722.19±29.69 Hounsfield单位。两种方法比较差异无统计学意义(P < 0.05)。平均肺体积为26±6.03 cm3。对蓝金刚鹦鹉和黄金刚鹦鹉肺解剖的正常计算机断层扫描和密度值的描述是有用的基线数据,可用于该物种呼吸系统疾病的诊断。
