Ultrasound is a primary imaging tool for thyroid and parathyroid localization. Classic thyroid and parathyroid tumors are easily distinguished by their sonographic appearance and location, but variations are common and complicate the distinction. Thus, biopsy under ultrasound guidance provides proof of the nature of the lesion. When parathyroid localization is problematic with ultrasound, magnetic resonance imaging is an excellent alternative.
超声是甲状腺和甲状旁腺定位的主要成像工具。典型的甲状腺和甲状旁腺肿瘤可通过其超声表现和位置轻松区分，但变异情况很常见，会使区分变得复杂。因此，超声引导下的活检可提供病变性质的证据。当超声对甲状旁腺进行定位有困难时，磁共振成像则是一个很好的替代方法。
