MRI and Ultrasound Elastography: Where Do We Stand? (2024)-S2-CMS01-2024

Video Transcription

Video Summary

The session led by Margarita Revzin, an associate professor at Yale Radiology, focused on MRI and ultrasound elastography. Key speakers included Dr. Richard Ammon from Mayo Clinic, Dr. Vito Cantisani from the University of Sapienza di Roma, Dr. Ronald Adler from NYU, Mira Tatyanovic from the University of New Mexico, and Arunak Kalipaka from Ohio State University. The discussion revolved around the physics of MR elastography, which uses shear waves to measure tissue stiffness, particularly effective for liver fibrosis. The consistency across manufacturers ensures comparable results globally. Emerging applications include brain diseases and differentiating tumors, with future potential in cardiac and pulmonary assessments.<br /><br />Ultrasound elastography, similarly based on shear waves, is valued for its accessibility and low cost. It's particularly useful in musculoskeletal assessments and situations where MRI is impractical. Despite variability among equipment, the technology is advancing in its application to thyroid nodules, salivary glands, and differentiating tissue types. The integration of AI and multi-parametric approaches holds promise for enhanced diagnostic accuracy. The session emphasized the importance of standardized protocols and potential future applications across various medical fields.
