3DUS can be used in ultrasonography for Small Parts, among other medical areas. The assessment of the parotid, thyroid and parathyroid glands is properly achieved. The Multiplanar presentation and Niche Mode are quite useful to determine the extension -inside or outside the organs-, of nodules, cysts or tumors. The VOCAL® makes it possible to obtain a proper after-treatment follow-up of focal disorders in these small organs. Neovascularization is clearly viewed with 3DUS and probably can suggest malignant origin of a neoplasm. 3DUS offers a more comprehensive image of anatomical structures and pathological conditions and also permits to observe the exact spatial relationships.

According our previous published results, 3DUS in Small Parts has an excellent conspicuity in 86.4%, moderate in 9.8% and poor in 3.8% . The feasibility was very easy in 65.2%, easy in 32.8% and difficult in 2% of the cases.
We are very aware more studies are needed to demonstrate specificity and sensibility of 3DUS in particular clinical conditions, not only in small parts but also in some other non-Ob/Gyn applications.
