Compared to other guidelines, ACR TI-RADS results in a decreased number of thyroid nodules which are either followed or given a recommendation of fine needle aspiration (FNA). Find out on this podcast hosted by Amber Liles, MD, MPH, what thyroid malignancies are missed and why and how changes in size thresholds might affect ACR TI-RADS performance and outcomes.

Lymph node staging in patients with invasive breast cancer and preoperative imaging of the axilla plays are essential for preoperative staging. Unlike many other areas of the body, it is the node morphology rather than size that is most revealing. Ultrasound not only allows visualization of nodes but also enables image guided biopsy. Accurate identification of axillary adenopathy can prevent unnecessary sentinel lymph node biopsy.

In this episode, Wei T. Yang reviews various imaging techniques and features for optimal management.
