چکیده

The irregularity of skin lesion borders is a significant diagnostic factor when assessing a lesion for malignancy. A ranking experiment involving irregularity assessment showed poor average ranking correlation among 20 experienced clinicians (r=0.44). However, for 50% of the group correlation was high (r=0.81), indicating high degree of consensus. A quantitative measure of irregularity based on fractal dimension, derived by computer image analysis, corresponded well to the assessment of this sub-group (r=0.88) but not to the assessment of the entire group (r=0.3). It i s proposed that only consensual data should be used as the basis for development and evaluation of medical image analysis algorithms.
