Abstract:
BACKGROUND: Although traditional plain scan and enhanced magnetic resonance imaging has been used for skeletal muscle imaging for many years, it is not enough to evaluate the microscopic changes of diseased tissue or the activity of diseased tissue. Dynamic contrast-enhanced magnetic resonance imaging can capture this information and advantages are shown in orthopedic imaging examination. OBJECTIVE: To review the progress of dynamic contrast-enhanced magnetic resonance imaging in orthopedics clinics. METHODS: The relevant documents from January 1900 to February 2020 were retrieved in the CNKI database, PubMed database, Web of Science and Wanfang database by computer. The search terms were “dynamic contrast-enhanced magnetic resonance imaging; skeletal muscle tumor; arthritis; spine; fracture” in Chinese, and “dynamic contrast enhanced magnetic resonance imaging (DCE-MRI); osteomuscular tumor; arthritis; spinal surgery; fracture” in English. RESULTS AND CONCLUSION: (1) At present, there is a general lack of consensus on the best scanning method for acquiring dynamic contrast-enhanced magnetic resonance imaging images and the ideal method for analyzing such images in clinical applications. The parameter analysis methods are mainly qualitative, semi-quantitative and quantitative analysis. (2) Dynamic contrast-enhanced magnetic resonance imaging has been widely used in non-invasive detection, qualitative and therapeutic monitoring of different diseases such as heart failure, breast cancer, prostate cancer, renal rejection and liver tumors. The clinical application in orthopedics is not mature enough, but has unlimited potential: It can be used to assess the blood flow after femoral neck fracture and to predict the viability of the femoral head, the regional perfusion of nonunion after fracture, bone perfusion of arthritis and other entities, and detection of deformed blood vessels. Compared with conventional imaging, in contrast, dynamic contrast-enhanced magnetic resonance imaging can also better assess the relationship between changes in lumbar spine perfusion, disc degeneration, and endplate perfusion at different stages.
