MICROIMAGING & SPECTROSCOPY OF MUSCLE DAMAGE

点击翻译按钮获取中文摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Throughout the progression of dystrophic myopathies, the affected muscle tissues undergo numerous cycles of degeneration and regeneration due to their high susceptibility to injury. Upon exhaustion of the regenerative capacity of these muscles, damaged fibers are progressively replaced by fat and connective tissue. These studies provide an essential foundation for both pre-clinical and clinical in vivo MR studies and address whether clinically approved extravascular contrast agents can detect acute membrane damage in dystrophic muscle.
