Myxoid soft tissue tumors (STTs) are
histologically unique group of tumors that have been proven to have
significantly higher ADC values than nonmyxoid counterparts. In addition, no
significant difference of mean ADC value exists between benign and malignant
myxoid STTs. We propose texture of ADC value as a new parameter for differentiating
benign and malignant myxoid STTs. The global (mean, standard deviation,
skewness and kurtosis), regional (intensity variability and size-zone
variability), and local features (energy, entropy, correlation, contrast,
homogeneity, variance and maximum probability) were extracted from ADC values of
each tumor group for texture analysis and statistical comparisons were
performed.
