Software for the analysis and serial classification of multiple sclerosis lesions was developed and tested. The system is based on the definition of a lesion complex (LC) which maintains a one to one correspondence between scans. A grammatically consistent labeling system was used to classify LCs in a chronological progression. The software forces a quality control check to ensure that the operator has not missed ROIs prior to the classification stage. The analysis time is significantly reduced for an operator; while the result has a higher credence by virtue of the forced quality control and grammatical consistency of the labels.
