Computed tomography of the chest or abdomen may reveal vertebral abnormalities. Images in multiple projections of dry and fresh specimens of the spine demonstrate that osteophytes, end-plate irregularities, and marked obliquity fail to mimic true osteoblastic vertebral lesions. Disk calcification may simulate a metastatic deposit if the section includes both disk and vertebral body. Abdominal or chest "window" settings produce an apparent increase in bone density. Analysis of the bony spine from abdominal and chest images requires gray scale settings different from those used for the study of visceral organs.
胸部或腹部计算机断层扫描可能显示椎体异常。脊柱干标本和新鲜标本的多个投影图像表明，骨赘、终板不规则和明显倾斜无法模拟真正的成骨性椎体病变。如果切片同时包括椎间盘和椎体，椎间盘钙化可能会模拟转移瘤。腹部或胸部“窗宽”设置会使骨密度明显增加。分析腹部和胸部图像中的脊柱骨骼需要与研究内脏器官时不同的灰度设置。
