We performed the VOI and ADC histogram analysis for malignant melanoma of the head and neck (MMHN) and compared these findings with keratinizing squamous cell carcinoma (SCC). The ADC distribution of MMHN had lower and right shifted peak than that of SCC which reflects lower MV, C10 and kurtosis. VOI and ADC histogram analysis with 3T-MRI has the potential to be useful for diagnosis of MMHN.
