ABSTRACT
The aim of our study are to determine the shape, vertebrae level, height, volume, corpus medial and lateral branch thicknesses of AG and the distance from some neighboring structures on multidetector computed tomography (MDCT) images and also to determine the relationship between these data and gender, age, height, weight and body mass index (BMI). The study was conducted on a total of 420 MDCT images consisted of 220 male (mean age 63.44±8.00, 50-81 years), 200 female (mean age 61.23±7.95, 50-84 years) healthy individuals. Vertebrae level of AG (VLAG), height of AG (HAG), adrenal gland volume (VAG), corpus thickness of AG (CTAG), medial section thickness of AG (MTAG) and lateral section thickness of AG (LTAG) were investigated. In our study, RAG were observed on T12 vertebrae level in 38.19 % of males and 42.5 % of females and LAG were also observed at that level in 39.55 % of the male and 51 % of the female individuals. RAG were observed in all males and 98.5 % of the females and LAG were observed 88.63 % of the males and 94 % of the females "Y" shaped. VAG were observed lower in males compared to females in age groups and VAG was observed increasing with age in males; decreased in 60-69 age group of females and increased again in 70 and plus age group. The aim of this study is to determine normal ranges of AG sizes and the relationship of each one with sex, age, height, weight and BMI.
Los objetivos de nuestro estudio fueron determinar la forma, el nivel vertebral, la altura, el volumen, el grosor de las ramas medial y lateral del cuerpo de glándulas suprarrenales (GSR) y la distancia de algunas estructuras vecinas en las imágenes de tomografía computada multidetector (TCMD) y determinar la relación entre estos datos y sexo, edad, estatura, peso e índice de masa corporal (IMC). El estudio se realizó en un total de 420 imágenes TCMD de 220 hombres (edad media 63,44 ± 8,00, 50-81 años) y 200 mujeres (edad media 61,23 ± 7,95, 50-84 años) todos sanos. Se investigó el nivel de la GSR respecto a las vértebras, la altura de GRS (AGSR), el volumen de la glándula suprarrenal (VGSR), el grosor del cuerpo, el espesor de la sección mediana de GSR (SMGSR) y el grosor de la sección lateral de GSR (SLGSR). En nuestro estudio, se observó la GSR derecha a nivel de vértebras T12 en el 38,19 % de los hombres y en el 42,5 % de las mujeres y la GSR izquierda se observó a ese nivel en el 39,55 % de los hombres y 51 % de las mujeres. La GSR se presentó en forma de «Y¼ en el lado derecho en todos los hombres y en el 98,5 % de las mujeres y en el lado izquierdo se observó en el 88,63 % de los hombres y 94 % de las mujeres. El VGSR era menor en los hombres en relación con las mujeres en los diferentes grupos de edad y aumentaba con la edad en los hombres; disminuyó en el grupo de 60-69 años de edad de las mujeres y aumentó nuevamente después de los 70 años.

BACKGROUND: Several studies suggested that epicardial adipose tissue (EAT) might be associated with metabolic syndrome and coronary atherosclerosis. But, little had been studied whether the thickness of EAT on echocardiography could represent the whole amount of EAT. The purpose of this study was to identify the best echocardiographic methods reflecting total amount of EAT. \METHODS: Sixty subjects (32 women, mean: 58+/-12 years-old) who underwent 64-slice multidetector computed tomography (MDCT) were consecutively enrolled. All CT scanning was performed one Brilliance CT-64-channel configuration scanner (Philips, Cleveland, USA) and axially contiguous 10-mm-thickeness sections were obtained from aortic valve to diaphragm level. EAT area was manually traced in each slice and summed up. The EAT thickness was measured as the echo-lucent or echo-dense space between epicardium and pericardium at parasternal long-axis, modified 4-chamber, and apical 4-chamber view. RESULTS: The EAT thickness at parasternal long-axis and modified 4-chamber view and the sum of EAT thickness from each views (median thickness: 1.0, 2.8, 1.1 and 5.0 mm, respectively) were all correlated with total EAT area on MDCT. Among echo parameters, the EAT thickness measured on parasternal long-axis view during diastole correlated best with total EAT area on MDCT (r=0.572, p<0.001). CONCLUSION: The echocardiographic EAT measurement might be easily accessible and less harmful method representing whole amount of EAT. The measurement of the thickness of EAT on parasternal long-axis view during diastole by echocardiography might be feasible and reliable in the studying field of EAT.

The presence and type of bronchial fistulas connected with various organs within the thorax were examined. The types of bronchial fistulas include bronchopleural, bronchoesophageal, adenobronchial, bronchomediastinal, bronchovascular, and other variants. The bronchopleural fistula included a central bronchopleural and peripheral bronchopleural fistula, as well as a bronchoesophageal fistula consisting of congenital and acquired fistula. Generally, an adenobronchial fistula generated by pulmonary tuberculosis or corrosive esophagitis. These conditions may have originated from bronchomediastinal and bronchovascula fistula. The computed tomography results revealed the connection of the bronchial fistula with organs and causative diseases. In addition, applying multiplanar reformatted images provided a the accurate location of bronchial fistula. In this type of clinical atlas, the type of bronchial fistulas and their imagings were introduced.
