As these nodules enlarge, some need to be removed with surgery just based on size alone. The good news is that this is actually quite rare. posteriorly:thyroid cartilage, cricoid cartilage, trachea, posteromedially:tracheo-esophageal groove (containing lymph nodes, recurrent laryngeal nerve, parathyroid glands), superior thyroid artery (from the external carotid artery), inferior thyroid artery (from the thyrocervical trunk), if the inferior thyroid artery arises from the subclavian artery it is referred to as an accessory inferior thyroid artery, superior thyroid vein (drains to the internal jugular vein), middle thyroid vein (drains to the internal jugular vein), inferior thyroid vein (drains via plexus to the brachiocephalic vein). The thyroid is imaged using a high-frequency linear transducer (715 MHz) with the patient lying supine with the neck in hyperextension.

P.S. Nature Reviews Endocrinology. The thyroid is best imaged using a high-frequency linear probe with the patient in a supine position with the neck hyperextended. The sagittal view shows mildl coarsening and heterogeneity of the echoexture. Thyroid gland.
