ABSTRACT Sixtysix patients were submitted to color Doppler ultrasonography, with flowmetric analysis, in the preoperative work up of their thyroid nodules. Three different groups (and two subsets) were so identified, corresponding to the different pathological nodule types: hyperplasia, adenoma, and cancer. The data obtained were then compared to the final pathological results. The color Doppler ultrasonography showed a diagnostic accuracy rate of 87.8%. An evaluation of the peak systolic velocity proved to be very useful in the differential diagnosis between adenomas and cancers. The color Doppler ultrasonography represents a sound method for evaluating thyroid nodules.

    ABSTRACT: The objective was to correlate the number, size and extent of the nodules as determined during the preoperative clinical examination of the thyroid gland, USG, intra-operative examination and histopathology. Also, FNAC (with or without USG guidance) and USG findings suggestive of malignancy were correlated with the final histopathology. Tertiary referral centre A retrospective chart review was done for 106 patients who underwent surgery for benign or malignant nodular thyroid disease in our center, between Jan 2004-Dec 2006. USG has 7 times higher predictive value than clinical examination in detecting number of nodules and determining size of nodules. USG guided FNAC has a sensitivity of 85.71% and specificity of 90.0% in detecting malignancy in nodular thyroid disease. However for predicting malignancy in thryoid nodules, this study shows that USG has a sensitivity of 20.0% and specificity of 97.67%. In patients with nodular thyroid disease, USG can accurately determine the number and the size of the nodules. It is extremely useful in guiding FNAC; However its role in predicting malignancy is doubtful. We therefore recommend that USG guided FNAC be carried out as a routine in the evaluation of thyroid nodules.
