Figure 5From: Value of diffusion weighted MR imaging as an early surrogate parameter for evaluation of tumor response to high-dose-rate brachytherapy of colorectal liver metastasesBoxplot depicting changes of mean volume of non-treated and treated tumors at early and follow-up MRI compared to baseline MRI. Boxplot shows changes of mean tumor volume (TV) of non-treated (*: p = 0.027) and treated colorectal liver metastases (*: p = 0.026) 2 days (early MRI) as well as 3 months (follow-up MRI) after HDR-BT as compared to baseline MRI.Back to article page
