Dr. Sonal Shah and Dr. Jyoti Mago (both Dental) co-presented their poster, “The Pivotal Role of Ultrasonography in Detecting Metastatic Head and Neck Cancers: A Review of Five Cases,” during the American Academy of Oral Medicine National Annual Meeting last month. The study found ultrasonography has superior soft tissue spatial resolution compared to CT and MRI, and uses non-ionizing radiation. The technique plays a critical role in the detection of lymph nodes in head and neck cancers with no hazards of radiation exposure. Ultrasonography also has the potential to detect early changes in alveolar bone, leading to earlier diagnoses of oral cancer.
