[Experimental studies of the visualization of the vertebral body spongiosa by high-resolution computed tomography].
OBJECTIVE
To show the accuracy and the lower limit of visualisation of cancellous bone in high-resolution computed tomography (HR-CT).


METHODS
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.


CONCLUSIONS
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.
