Figure 3.
(A) MR images of baseline (BL) and follow-up MRI of a lung cancer patient with a partial response after initiation of bevacizumab-based treatment. Partial response is seen both on FLAIR (upper row) and T1-weighted (lower row) images. (B and C) MR imaging examples of patients with breast cancer (B) and colorectal cancer (C) showing partial response on FLAIR and complete response on T1-weighted images after Gd-contrast administration (B) on follow-up MRI. Note that the tumor volume (central core) and perifocal edema can be differentiated on FLAIR images.
