Comparison of the performance of the previously reported CAD scheme with that of the MTANN-based CAD scheme at different stages.

Previously reported CAD scheme		MTANN-based CAD scheme
Nodule candidate detection by multiple thresholding	96% sensitivity with 19.3 FPs/section	Nodule candidate detection by MTANN	97% sensitivity with 6.7 FPs/section
Feature analysis and rule-based scheme	96% sensitivity with 9.3 FPs/section	Classification by MTANN	96% sensitivity with 2.7 FPs/section
Classification by LDA	84% sensitivity with 1.4 FPs/section		84% sensitivity with 0.5 FPs/section
