Currently, magnetic resonance imaging (MRI) is used 1-3 months after treatment to evaluate anatomical tumor response, based upon changes in tumor size and contrast-agent enhancement.
Objective: to evaluate the clinical value of bolus injection with large dose of contrast agent by power injector on MR imaging of metastatic brain tumor and in application of MRA.
目的：探讨大剂量对比剂注射器团注在脑转移瘤及其血管成像中的临床意义。
