To show the accuracy and the lower limit of visualisation of cancellous bone in high-resolution computed tomography (HR-CT).
18 native human lumbar vertebrae were placed in a water phantom and examined by HR-CT. The scans were compared with contact radiographs of correlating thin bone sections by morphologic criteria.
The measured lower limit of visualisation of cancellous bone structures is clearly worse than expected from the measurements of spatial resolution with standard phantoms used for HR-CT (0.6 versus 0.4 mm). True and exact imaging of normal cancellous bone cannot be achieved even by modern HR-CT. Noise creates structures mimicking cancellous bone.
展示高分辨率计算机断层扫描（HR-CT）中松质骨可视化的准确性和下限。
将18个新鲜的人腰椎椎体置于水模中，并用HR-CT进行检查。通过形态学标准将扫描结果与相关薄骨切片的接触式X线照片进行比较。
松质骨结构可视化的测量下限明显比使用用于HR-CT的标准模体进行空间分辨率测量所预期的要差（0.6毫米对0.4毫米）。即使是现代的HR-CT也无法实现正常松质骨的真实准确成像。噪声会产生类似松质骨的结构。
