About the Lab
Professor In-Sun Yoo's research lab specializes in diagnostic radiology with a focus on medical imaging applications in head and neck disorders, particularly in the differentiation and characterization of inflammatory and neoplastic conditions. The lab investigates advanced ultrasound and MRI techniques to improve the accuracy of non-invasive diagnosis, with key research directions including the ultrasonographic and radiological features of tuberculous lymphadenitis and Kikuchi disease, the role of T1-weighted MRI in detecting sinonasal fungus balls, and the use of 3D ultrasound for precise parathyroid volume measurement. The lab also emphasizes clinical outcomes in elderly patients with thyroid cancer, using imaging to predict recurrence and guide management.

4Background: Central dark-signal intensity with high-signal, hypertrophic mucosal wall of paranasal sinuses on T2-weighted images (T2WI) is a characteristic magnetic resonance imaging (MRI) feature of sinonasal fungus ball. However, this finding is usually interpreted as non-fungal chronic sinusitis with central normal sinus air. In addition, T1-weighted images (T1WI) and T2WI are basic sequences of all magnetic resonance (MR) examinations. Therefore, we evaluated the usefulness of T1WI for detec
Although tuberculous lymphadenitis and Kikuchi disease are common causes of cervical lymphadenopathy in Asians and exhibit similar clinical manifestations, their treatment strategies are totally different. The purpose of this study was to identify ultrasonographic features that distinguish these two diseases. This study was approved by the Institutional Review Board. The study included 77 patients with tuberculous lymphadenitis and 135 patients with Kikuchi disease. The sex and age distributions
Purpose: The purpose of this study was to investigate the accuracy and reliability of the semiautomated ultrasonographic volume measurement tool, virtual organ computer-aided analysis (VOCAL), for measuring the volume of parathyroid glands. Methods: Volume measurements for 40 parathyroid glands were performed in patients with secondary hyperparathyroidism caused by chronic renal failure. The volume of the parathyroid glands was measured twice by experienced radiologists by two-dimensional (2D) a
Purpose: The aim of this study was to assess the characteristics of papillary thyroid carcinoma (PTC) in patients aged 65 and older in order to predict postoperative recurrence based on the results of ultrasonographic surveillance. Methods: Among 1,494 patients (200 male and 1,294 female; mean age, 46.6±11.3 years) who underwent surgery for thyroid cancer at our institution between 2006 and 2015, we retrospectively enrolled 150 PTC patients (29 male and 121 female; mean age, 69.4±4.2 years) aged
