Role of MR imaging in sports medicine research. Basic science and clinical research studies.

The advent and advancement of MR imaging have provided an entire new dimension for medical imaging. MR imaging has been especially useful because of its capacity to image nonmineralized tissues with a very high degree of resolution. Although modalities such as ultrasound and scintigraphy have proven useful for specific purposes, it is MR imaging that has the most utility and capabilities, especially in the area of sports-induced injuries. The technology associated with MR imaging has expanded greatly, and it continues to evolve at a rapid pace. The result has been an ever-increasing diagnostic capability that has become more economic with time. As described previously, MR imaging is gaining importance in the area of comparative medicine for animal athletes as well. It is also interesting to note that MR imaging now has a greater potential for monitoring physiological and biochemical changes as well as anatomic ones. Some newer MR units actually include physiologic data acquisition components. Consequently, new bioassays and nondestructive tissue tests can be performed to further understand the molecular biology and ongoing cellular processes in any given condition. Coupled with MR spectroscopy, the enhanced MR techniques should continue to contribute to the overall information that will be integrated into the training and rehabilitation of patients with sports-induced inflammation and injuries. The authors support and encourage ongoing efforts in the area of MR imaging research, both basic science and clinical studies.
