Unlabelled:
We evaluated the feasibility of cone-beam tomography (SPECT with a converging collimator) for detecting bone pathology of the distal extremities.
Methods:
We examined 11 patients: seven with hand or wrist pain, three with ankle pain and one with tibial pain. Cone-beam tomography was performed using a high-resolution converging collimator with a 45-cm focal length. Tomograms were then compared to high-resolution planar images.
Results:
Cone-beam tomography was successfully performed in all patients and tomograms were reconstructed in time for inclusion in the clinical report. In five patients, cone-beam tomography identified abnormalities that were equivocal or poorly defined on planar images. All other cone-beam studies provided the same information as the planar images.
Conclusions:
Tomographic imaging of the distal extremities can be successfully performed by using cone-beam tomography which has been found to be feasible and potentially useful in the clinical setting.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
