Receiver operating characteristic curve of enhancement scope, calcification and enhancement scope combined calcification. AUCenhancement scope + calcifications vs. AUCmicrocalcification, P < 0.0005; AUCenhancement scope + microcalcifications vs. AUCenhancement scope, P = 0.007; AUCmicrocalcifications vs. AUCenhancement scope, P = 0.011
