Descriptor	Sensitivity	Specificity	Positive predictive value	Negative predictive value	Diagnostic accuracy
A	81.8%	16.6%	70.5%	20%	62.9%
B	70.45%	83.3%	91.61%	53.5%	74.69%
C	70.45%	83.3%	91.61%	53.5%	74.69%
D	63.6%	77.7%	87.5%	46.6%	67.74%
E	40.9%	77.7%	81.8%	35%	51.6%
F	50%	44.4%	54.5%	20%	32.2%

Descriptors: A: size more than 10 mm; B: loss of fatty hilum; C: Hypoechoic internal echo; D: round shape; E: sharply demarcated border; F: asymmetric cortical thickening with or without eccentric lobulation.
