Emission tomography: its contribution in the detection of subdural haematoma.

The technique of emission computed tomography (ECT) was assessed with regards to its value in the detection of subdural haematoma. Results from an anthropomorphic head phantom and a short clinical trial both showed promising signs of better differentiation between normal and abnormal in equivocal results. A simple quantitative index was used to compare ECT with static imaging. The conclusion is that ECT is of value in those patients whose scan results are otherwise equivocal.
