The clinical usefulness of scintigraphy with thallium-201 (201Tl) chloride injection was evaluated in 79 patients with suspected bone, soft tissue or mediastinal tumors. No abnormal changes of subjective or objective signs and clinical test values were observed post injection. It is considered that 201Tl chloride is a safe radiopharmaceutical. In comparison with benign tumors, malignant tumors showed longer retention or more increased uptake of the 201Tl in the lesions on delayed images. The results suggested that the evaluation of changes of 201Tl uptake might be useful to some extent to differentiate malignant tumor from benign tumor. It is considered that 201Tl scintigraphy is useful for evaluating the location and extent of tumor and differentiating malignant from benign tumor.

Optimizing the graft size in the Evans osteotomy to minimize the calcaneocuboid joint pressure by highly realistic in-silico analysis.
Sci Rep
January 2025
Division of Mechanical and Biomedical Engineering, Ewha Womans University, Seoul, 03760, Republic of Korea.
This contribution details a new high-fidelity finite element analysis (FEA) methodology for the investigation of the effect of the graft size on the pressure distribution developing at the calcaneocuboid joint after the Evans osteotomy procedure. The FEA model includes all 28 bones of the foot up to the distal end of fibula and tibia as well as soft tissues, tendons, and muscles. The developed FEA model was validated by comparing the in-vivo pressure distribution on the foot plantar with the in-silico results, resulting in a low deviation equal to 7.

Role of radiofrequency ablation in the treatment of symptomatic distant metastasis of thyroid cancer.
Skeletal Radiol

Department of Radiology and Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, 86 Asanbyeongwon-Gil, Songpa-Gu, Seoul, Korea.
Objective: To evaluate the effectiveness and safety of radiofrequency ablation (RFA) for the treatment of symptomatic distant metastasis of differentiated thyroid carcinoma.
Materials And Methods: The medical records of 12 patients who underwent RFA for the palliative treatment of 18 symptomatic distant metastases from thyroid cancer between January 2008 and December 2020 were analyzed. All patients were assessed for their degree of discomfort and underwent periodical evaluations as outpatients, including clinical examination, imaging, and serologic markers.
Topographic Analysis of the Periorbital Region Including Orbicularis Oculi Muscle Based on Ultrasonography Interpretation.
J Cosmet Dermatol
January 2025
Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, Seoul, South Korea.
Objective: Ultrasonographic examination is easy, fast, safe, and used in various fields; however, its application to the facial area has been limited. Complex anatomical structures are mixed within thin, soft tissues in the facial region; therefore, understanding their structural characteristics is crucial. This study aimed to use ultrasonography to obtain information on the layered structure and soft tissue thickness of the eye area around the orbicularis oculi muscle and provide guidance for clinical practice.

Purpose: The study conducts a comparative analysis between two prominent methods for fabricating composites for bone scaffolds-the (solid) solvent method and the solvent-free (melting) method. While previous research has explored these methods individually, this study provides a direct comparison of their outcomes in terms of physicochemical properties, cytocompatibility, and mechanical strength. We also analyse their workflow and scalability potentials.
