Blom RLGM et al. – This study shows no additional value of external ultrasonography to a negative PET–CT. According to the results, it can be omitted in the primary workup. However, suspect lymph nodes on PET–CT should be confirmed by FNA to exclude false positives if it would change treatment plan.
