Preoperative Staging of Differentiated Thyroid Carcinomas: Comparison of USG and CT with Intraoperative Findings and Histopathology.

To study the efficacy of USG and CECT in preoperative staging of differentiated thyroid carcinomas in comparison to the intraoperative and histopathological findings. A prospective, observational study was conducted in a tertiary care hospital over a period of one and a half years where USG and CECT of 23 subjects with histopathologically proven differentiated thyroid malignancy were analysed to study the characteristics of the primary tumour, lymphatic metastasis and evaluate the sensitivity and specificity of the radiological investigations in comparison to the intra-operative and histopathological findings. When compared with intraoperative and histopathological T-staging, USG had an accuracy of 69.
