BRAF and thyroid nodule: We propose, as a study line, the combination of thyroid US with BRAFV600E from residual FNAC material and functional imaging using oncological 99mTc-MIBI radiotracer wash-out of thyroid nodules, the aim being to develop a functional imagistic pattern for suspicious thyroid nodules and also to correlate presurgical molecular findings (BRAF mutation) with the final histopathological result.
