| Abstract: | PurposeTo evaluate the efficacy of apparent diffusion coefficient (ADC) calculation in differentiation between malignant and benign thyroid nodules.Methods and materialsA prospective study was conducted in 52 patients. Diffusion-weighted echoplanar imaging was performed and b factors were taken as 0 and 400 s/mm2.ResultsThe mean ADC value for malignant thyroid nodules was 0.829±0.179×10?3 mm2/s and that for benign thyroid nodules was 1.984±0.482×10?3 mm2/s. The mean ADC value for malignant nodules was significantly lower than that for benign nodules (P=.0001).ConclusionADC value calculation is an effective method in differentiation of malignant thyroid nodules from benign ones. |
