ABSTRACT
It was aimed to determine the anatomical structures in thoracic cavity by computed tomography imaging (CT) and compare the cross sectional images in the same specimens which were plastinated after CT imaging. It was also aimed to obtain 3 dimensional (3D) reconstructions of thoracic anatomical structures. Thoracic organs of 3 adult cats were CT imaged and then plastinated in this study. Specimens were plastinated in the same body position in the CT imaging process. CT images and corresponding plastinated cross sections were compared to each other. Anatomical structures of the thoracic cavity in plastinates were in accordance with CT images. Beside the bony structures, other organs such as esophagus, trachea, heart with related vessels, lungs and thoracic muscles were well defined in CT images and plastinates. Moreover, 3D reconstructed images of anatomical structures of thoracic cavity were acquired well. This study is thought to be beneficial for veterinary surgery and radiology fields as well as veterinary anatomy educations.
El objetivo de este trabajo consistió en determinar las estructuras anatómicas en la cavidad torácica mediante tomografía computarizada (TC) y comparar las imágenes transversales en las mismas muestras, que fueron plastinadas después de la TC. También se pretendía obtener reconstrucciones tridimensionales (3D) de estructuras anatómicas torácicas. Se tomaron imágenes de los órganos torácicos de 3 gatos adultos por TC y luego se plastinaron en este estudio. Las muestras se plastinaron en la misma posición corporal en el proceso de obtención de imágenes TC. Las imágenes de TC y las secciones transversales plastinadas correspondientes se compararon entre sí. Las estructuras anatómicas de la cavidad torácica en los preparados plastinados estaban de acuerdo con las imágenes de CT. Además de las estructuras óseas, otros órganos como el esófago, la tráquea, el corazón con vasos relacionados, los pulmones y los músculos torácicos estaban bien definidos en las imágenes de TC y los plastinados. Por otra parte, se captaron bien las imágenes reconstruidas en 3D de las estructuras anatómicas de la cavidad torácica. Pensamos que este estudio es beneficioso para la cirugía veterinaria y los campos de radiología, así como también para la educación de anatomía veterinaria.

PURPOSE: We wanted to measure the vascular pedicle width (VPW) in normal Korean adults and correlate the VPW with the body physique and we also wanted to establish the index for normal VPWs, which could be utilized in reading chest PAs. MATERIALS AND METHODS: The VPW was measured on the posteroanterior (PA) chest radiographs of 262 normal Korean adults (134 men and 128 women, age range: 22-88 years, mean age: 45.2 years), who visited the hospital for a general health examination. The relationship between the VPW and the height and the Body Mass Index (BMI) was evaluated. Correlations between height and the thoracic spine length (TSL) and between the BMI and the lateral chest wall thickness (CWT) were analyzed as well. RESULTS: The mean VPW was 47.4 (+/-6.4) mm. The VPW was positively correlated with the height (p<0.01) and the BMI (p<0.01) of the subject. The patient's height was well correlated with the TSL, and the BMI was correlated with the CWT (r=0.75, r=0.76). The table for the normal VPWs according to patient's TSL and CWT was established. CONCLUSION: By measuring the TSL and the CWT on chest PA, which reflect the height and BMI, respectively, and by utilizing the provided table for the normal VPW, we can determine the normality of a patient's VPW.

Pectus excavatum in which the sternum is depressed and the anterior chest wall is concave in shape, is the most common congenital deformity to affect this region of the body. Various deformities involving depression or protrusion are caused by the degree and location of the sternal depression, and associated deformities such as a tilted sternum and anterior convexity of costal cartilages may occur. The most common associated disorders are Poland syndrome, Marfan syndrome and scoliosis.
