Abstract:
The growth of brain metastasis needs appropriate microenvironment, and the change of normal brain microenvironment is the basis for exploring metastasis with MRI. Through the local magnetic field changes and the application of contrast agents for improving the discrepancy of the cerebral tissue, MR can accurately detect brain metastasis in position, number, size, and shape. MR with contrast-enhanced technique is the first choice for screening brain metastasis. The application of all kinds of new MR techniques, sequences and intracellular contrast agents can not only further improve the specificity of detection, but also improve the sensitivity of MRI, which is favorable to formulating reasonable treatment and prolonging the lifetime of the patients. The microenvironment of brain metastasis and advances in the new MR techniques were reviewed in this article.
