The purpose of this study was to evaluate the effect of slice thickness on the performance of a lung nodule CAD algorithm for chest CT. The study involved 28 patients with a total of 33 nodules. Each case was scanned at 0.9 mm slice thickness and reformatted at 1.8 mm and 2.7 mm. Statistical analysis showed significant differences in the sensitivity of the CAD software between the 0.9 mm and 2.7 mm, and the 1.8 mm and 2.7 mm datasets, showing that the performance of the CAD algorithm deceases significantly with the increase in slice thickness.
