BPL, benign-pigmented lesions; EEI, entry echo image; LBI, lesion backscatter image; MM, malignant melanoma; RTI, Reflex transmission image; SD, standard deviation.
Negative values indicate that on average, the mean for echo values within the lesion is higher than that outside the lesion boundary.The asterisks indicate those parameters that show a significant difference between means (P<0.05).
