Assessing Response to Radiation Therapy Treatment of Bone Metastases: Short-Term Followup of Radiation Therapy Treatment of Bone Metastases with Diffusion-Weighted Magnetic Resonance Imaging

Figure 2

MRI: before therapy ((a), (b), (c), (d)), 33 days after therapy ((e), (f), (g), (h)), and 64 days after therapy ((i), (j), (k), (l)). The bone metastases hypointense on T1-weighted images ((a), (e), (i)) appear similarly hyperintense on DW images obtained using low b-value ((b), (f), (l)), whilst the inner signal intensity variation after treatment is better highlighted comparing with images obtained using high b-value ((d), (h),(l)).
