Summary
52 bone lesions in 44 patients of known cancer were
rated as indeterminate with SPECT alone. Majority
of the indeterminate lesions were in ribs and the
scapula.
When corresponding SPECT•CT images were
analyzed, 92% of the indeterminate lesions were
classified as definitively benign or definitively
malignant based on correlation between SPECT and
CT findings. Only 8% (4 lesions out of 52) remained
indeterminate after analysis of SPECT·CT images.

Study Results and Conclusion
SPECT-guided CT was able to clarify more than 90%
of SPECT findings classified as indeterminate*,
thus considerably shortening the diagnostic
process.
SPECT-guided CT has the potential to reduce
patient radiation exposure, by limiting the CT scan
to the body region of interest identified by SPECT.
* In an analysis blinded to clinical pretest probability and planar scans.
