CEUS and location features were analyzed using multivariable logistic regression to construct the modified system. Diagnostic performance and biopsy recommendation efficiency were compared with ACR TI\u2010RADS.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Four hundred and eight patients with 442 nodules were included. Independent predictors included enhancement intensity, enhancement direction, ring enhancement, enhancement area and nodule location. In the training set (\n n<\/jats:italic>\n \u2009=\u2009334), the modified system achieved higher AUC and sensitivity than ACR TI\u2010RADS (AUC: 0.90 [95% CI: 0.86\u20130.93] versus 0.75 [95% CI: 0.71\u20130.79]; sensitivity: 88.5% versus 60.3%;\n p<\/jats:italic>\n \u2009<\u2009.01), higher accuracy of malignant nodule biopsies (AMB: 67.1% versus 49.4%), lower unnecessary biopsy rate (UBR: 32.9% versus 50.6%), and lower biopsy rate of benign nodules (BRB: 20.8% versus 31.2%), with no unsafe downgrading. Similar results were observed in the temporal validation set (\n n<\/jats:italic>\n \u2009=\u2009108): AUC 0.95 (95% CI: 0.90\u20130.99) versus 0.73 (95% CI: 0.66\u20130.79); sensitivity 87.0% versus 49.3%; AMB 83.3% versus 53.3%; UBR 16.7% versus 46.7%, and BRB 5.1% versus 17.9%.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n A modified ACR TI\u2010RADS integrating CEUS features and nodule location improved diagnostic performance and FNA recommendations for ACR TR4 or higher nodules.
