Performance of Advanced Practice Providers compared with that of Physicians in Ultrasound-Guided Fine-Needle Aspiration of Thyroid Nodules and Superficial Neck Masses.

Advanced practice providers (APPs) perform ultrasound (US)-guided fine-needle aspiration (FNA) procedures for superficial neck lesions after appropriate training in some interventional radiology practices. This allows physicians additional time to be involved in more complex procedures. This report compared the performance between physicians and APPs.
