Abstract

This report describes the normal radiographic and ultrasonographic morphological features of premature minipigs at 4, 8, 12 and 20 weeks of age. Radiographic examination is a simple diagnostic method used to identify the general morphologic state of major organs and their adjacent structures, and to assess the presence of abnormalities. The parameters for evaluation in plain abdominal radiographs are the degree of diffuse serosal margin details, extent of visualization of each organ, their size, shape, and contour, locations of main organs - such as the liver, stomach, spleen, kidneys, urinary bladder - the distribution of the intestines, and assessment of the retroperitoneal space and its contents. Ultrasonographic examinations are used to investigate their internal condition. The parameters for evaluation in abdominal ultrasonography are echogenicity, echotexture, and size and shape of the main organs such as the liver, spleen, kidney, urinary bladder and gastrointestinal tract. Minipigs had similar findings compared to dogs or cats.

4, 8, 12, 20 주령의 미성숙 미니돼지에서 방사선과 초음파를 이용하여 복부 주요 장기의 형태학적 특징을 살펴보았다. 방사선 검사는 전반적인 장기의 형태를 확인하는 데 이용되는 가장 기본적이고 단순한 방법이다. 기본 복부방사선 사진에서 이용되는 평가해야 할 항목들은 우선 전반적인 복부세부음영의 정도, 간, 위, 비장, 신장, 방광, 장들의 위치, 크기, 형태, 변연, 후복강 평가이다. 초음파 검사는 이러한 주요 장기들의 내부 실질을 평가하는 데 주로 사용된다. 미니돼지는 개와 고양이와 비교했을 때 유사한 소견을 가진 것을 확인하였다.
