Quantitative evaluation of diffusion-weighted MRI for differentiating benign and malignant thyroid nodules larger than 4 cm.

ABSTRACT:

Purpose

Our study aimed to diagnose benign or malignant thyroid nodules larger than 4 cm using quantitative diffusion-weighted imaging (DWI) analysis.

Methods

Eighty-two thyroid nodules were investigated retrospectively and divided them into benign (n = 62) and malignant groups (n = 20). We calculated quantitative features DWI and apparent diffusion coefficient (ADC) signal intensity standard deviation (DWI_SD and ADC_SD), DWI and ADC signal intensity ratio (DWI_SIR and ADC_SIR), mean ADC and minimum ADC value (ADC_mean and ADC_min) and ADC value standard deviation (ADC_VSD). Univariate and multivariate logistic regression were conducted to identify independent predictors, and develop a prediction model. W
