Abstract:
BACKGROUND: As a non-invasive detection method, dynamic contrast-enhanced magnetic resonance imaging is widely used in the field of tumor. It can be used for the differentiation of benign and malignant tumors, the grading of tumor grade and the prediction and evaluation of prognosis. In recent years, the application research in the field of bone and joint has gradually become a hot spot, which can be used in the determination of bone marrow blood perfusion, the evaluation of bone tissue activity, the early detection of bone perfusion abnormality and the evaluation of blood circulation of joint inflammatory lesions. OBJECTIVE: To summarize the technical situation of dynamic contrast-enhanced magnetic resonance imaging and its application research in bone and joint. METHODS: The keywords were “(bone OR joint) AND (dynamic contrast-enhanced MRI) OR dynamic contrast-enhanced magnetic resonance imaging) OR DCE-MRI” in English and Chinese, respectively. The first author searched PubMed, Springerlink and China National Knowledge Infrastructure databases for the articles published between 1984 and 2019. The relevant literature was reviewed on the application of dynamic contrast-enhanced magnetic resonance imaging in bone and joint in recent years. Finally, 55 articles were summarized and analyzed. RESULTS AND CONCLUSION: (1) At present, dynamic contrast-enhanced magnetic resonance imaging technology and data processing have not been standardized. T1WI imaging is mainly used in bone and joint. Qualitative, semi-quantitative and full quantitative analysis of its data is feasible. (2) Qualitative analysis and semi-quantitative analysis are simple and easy to operate. Quantitative indicators are clear, can objectively describe the shape of the curve, but cannot reflect the concentration of contrast agent between tissues and blood vessels, and are easily affected by the sequence of scanning parameters, so cannot detect the pharmacokinetic information of tissue. Quantitative analysis can obtain the concentration changes and generation parameters of contrast media between substructures in tissues, and evaluate the microangiogenesis and function of tissues. (3) Dynamic contrast-enhanced magnetic resonance imaging can noninvasively evaluate the microcirculation perfusion of bone and joint. It has certain reference value for the discussion of the pathogenesis, diagnosis and differential diagnosis, prediction of prognosis, evaluation of curative effect and choice of treatment of many bone and joint diseases.
