Deep learning-based quantitative estimation of lymphedema-induced fibrosis using three-dimensional computed tomography images

Quantitative 3D-CT imaging of sarcopenia mitigation in the elderly: evidence from a case report

This case study examines the effectiveness of using combined CT imaging and 3D imaging in monitoring the prevention of sarcopenia through continuous daily exercises in an elderly patient. Using a 256-slice CT scanner with dose reduction technology and advanced muscle segmentation with the open-source software DAFNE, we compared changes in muscle mass and density in a 70-year-old patient in 2014 and in 2023. The obtained images allowed the creation of detailed 3D models for a more accurate and intuitive assessment of the leg musculature. Despite aging, the results of the scans performed at the beginning and end of the study period did not show significant changes in the patient's musculature, suggesting that a persistent Full-Body in-Bed Gym protocol ("Gym Bed" exercise routine) can effectively contribute to maintaining muscle mass and density in the elderly. These preliminary results highlight the potential of advanced imaging techniques not only to diagnose but also to quantify the effectiveness of non-pharmacological interventions against sarcopenia.

The Role of Imaging of Lymphatic System to Prevent Cancer Related Lymphedema

Lymphedema is a progressive chronic condition affecting approximately 250 million people worldwide, a number that is currently underestimated. In Western countries, the most common form of lymphedema of the extremities is cancer-related and less radical surgical intervention is the main option to prevent it. Standardized protocols in the areas of diagnosis, staging and treatment are strongly required to address this issue. The aim of this study is to review the main diagnostic methods, comparing new emerging procedures to lymphoscintigraphy, considered as the golden standard to date. The roles of Magnetic Resonance Lymphangiography (MRL) or indocyanine green ICG lymphography are particularly reviewed in order to evaluate diagnostic accuracy, potential associations with lymphoscintigraphy, and future directions guided by AI protocols. The use of imaging to treat lymphedema has benefited from new techniques in the area of lymphatic vessels anatomy; these perspectives have become of value in many clinical scenarios to prevent cancer-related lymphedema.
