Explore the advanced techniques of macromolecular mapping using Magnetic Resonance Imaging (MRI) in this comprehensive lecture. Delve into the essential role of macromolecular mapping in biomedical and clinical research, with a focus on determining myelination patterns in the central nervous system. Learn about the limitations of conventional MRI in providing direct information about macromolecular content and discover how multi-component mathematical analysis can overcome these challenges. Examine the complexities of extracting macromolecular signals through MR relaxometry and related techniques, including the use of inverse Laplace transform and its associated challenges. Gain insights into specialized methods developed to address the ill-posed inverse problem and produce meaningful results. Explore practical applications of these advanced techniques in myelin mapping in the central nervous system and proteoglycan mapping in cartilage. Understand the dual goals of improving MR evaluation of tissue pathology and developing methods applicable to inverse problems more broadly.
