Inter-observer agreement in describing the ultrasound appearance of adnexal masses and in calculating the risk of malignancy using logistic regression models.
Purpose: To estimate inter-observer agreement with regard to describing adnexal masses using the International Ovarian Tumor Analysis (IOTA) terminology and the risk of malignancy calculated using IOTA logistic regression models LR1 and LR2, and to elucidate what explained the largest inter-observer differences in calculated risk of malignancy. Experimental Design: 117 women with adnexal masses we
