This purpose of this study was to describe and compare the radiographic and computed tomographic(CT) appearance of the experimentally induced Legg-Calve-Perthes Disease(LCPD) in dogs. LCPD was experimentally induced at the left femoral head in 7 litters of a dog. The lesions were evaluated with radiography, CT, and contrast CT every week from day 7 to day 70 after operation. Histopathologic examination was performed on 92th day after operation. Every images were evaluated according to the staging system of the osteonecrosis published by Association Research of Circulation Osseous in 1997 and the scoring(0-4). On CT scan, diffuse porotic lesion and focal sclerotic lesion were detected on day 14 and on day 21 after operation, respectively. Subchondral fracture, articular collapse and crescent sign with decreased attenuation were shown on day 28 after operation for the first time and no change of the sign were detected from operation day 9 to day 70 after operation. Focal porotic lesion and irregular radiopacity of femoral head were detected on day $41{\pm}7.48$ and on day $51{\pm}5.29$ after operation respectively on radiographs. In scoring evaluation, 2.00 was scored on day 14 after operation on CT scan, on day 56 after operation on radiographs, respectively This study has shown that CT is more suitable for early diagnosis of LCPB and has superior sensitivity than radiography. Also, CT has been expected to be important for staging and treatment of LCPD.

7개월령 암컷 포메라니안견이 오른쪽 후지 파행 증상으로 내원하였다. 내원시 신체 검사에서 오른쪽 대퇴 관절을 신장하였을 때 통증을 호소하였고 일반 방사선 사진에서 오른쪽 대퇴골두에 미약한 방사선 투과성 병변과 오른쪽 대퇴관절 공간의 확장을 확인하였다. 14일 후 일반 방사선 사진에서 오른쪽 대퇴골두 골단의 변위를 확인하였고 컴퓨터단층촬영에서 오른쪽 대퇴골두에 저음영의 병변과 골절선을 확인하였다. 오른쪽 대퇴골두 절제술을 실시하였고 조직학적 검사에서 골두 골간단과 골단의 괴사를 확인하였다. 본 증례는 초기 허혈성 대퇴골두 괴사증이 있는 개의 방사선학적, 컴퓨터단층촬영, 수술적, 조직학적 소견을 기술하였다.
