Fig. 4

a, b & c demonstrate treatment planning for a recurrent glioblastoma patient with diffuse infiltrating disease. Figure a shows the T1 with contrast axial slice demonstrating enhancing tumor. Figure b demonstrates more diffuse FLAIR signal abnormality, including within the contralateral lobe. As such, treatment is planned using the FLAIR sequence. Standard measurements were performed from a reference frame drawn at the outer margin of the scalp. Tumor location coordinates are obtained on the axial slice measuring from the right frame to the proximal and distal extents of FLAIR abnormality. In the absence of a coronal FLAIR sequence, coronal treatment planning is performed using the T1 postcontrast sequence (figure c). In this slice, the inferior margin of the reference frame is drawn to the lowest visible level of tentorium
