Head And Neck SSA16-01 Is Magnetic Resonance Tractography of Intraparotid Facial Nerve Useful in Patients with Malignant Tumors?

The advent of minimally invasive parathyroid surgery (MIPS) has driven the development of improved localization techniques for parathyroid adenoma. The most successful imaging techniques are those that combine excellent anatomic detail with functional information that will help differentiate parathyroid adenoma from other nodules in the region. Ultrasound remains a very useful modality, because of its availability, cost and absent ionizing radiation. Radionuclide scanning, typically utilizing Tc99m Sestamibi, adds more specific functional information, and when combined with CT, good anatomic detail. Recently, there has been increasing interest in parathyroid CT, also known as 4DCT. This is essentially a CTA study whereby the characteristic hyperperfusion of parathyroid adenomas allows them to be differentiated from lymph nodes and exophytic thyroid nodules. There remains considerable controversy regarding technical details of 4DCT, particularly the number of phases required. The associated ionizing radiation remains a significant concern. Often, a combination of two imaging modalities is performed in order to increase reliability.The high incidence of ectopic parathyroid glands, the position of the glands at the root of the neck, the proximity to often multinodular thyroid tissue and what appears to be a rising incidence of multi glandular disease are challenges that relate to all imaging modalities.
