本文对20例犬原发骨肿瘤标本(骨肉瘤18例，纤维肉瘤2例)进行了检查，并将大体肿瘤的最大轴向长度与术前X线片和99mTc-亚甲基二磷酸盐骨显像所显示的病变长度进行了比较。X线片将肿瘤长度定义为肉眼测量的+/-10%以内的6例(30%)，低估的12例(60%)，高估的2例(10%)。骨显像将肿瘤长度定义为+/-10%以内的8例(40%)，低估肿瘤长度的1例(5%)，高估其余11例(55%)的肿瘤长度。单纯使用放射学评估可能导致低估原发骨肿瘤的骨干范围，并有不完全切除的风险。骨扫描图像往往高估了肿瘤的长度，因此可能提供更安全的切除指南。
Specimens of 20 canine primary bone tumors (18 osteosarcoma, 2 fibrosarcoma) were examined to compare the maximal axial length of gross tumor with the length of the lesion seen on preoperative radiographs and 99mTc methylene diphosphonate bone scintigraphic images. Radiographs defined the length of the tumor to within +/- 10% of the gross measurement for 6 (30%), underestimated it for 12 (60%), and overestimated it for 2 (10%) specimens. Bone scintigraphy defined tumor length within +/- 10% for 8 (40%), underestimated it for 1 (5%), and overestimated it for the remaining 11 (55%) specimens. Use of radiographic evaluation alone could result in underestimation of the diaphyseal extent of a primary bone tumor, with risk of incomplete resection. Bone scan images tend to overestimate tumor length and, therefore, may provide safer resection guidelines.
