a, b & c: Figure a demonstrates post-operative loss of contrast-enhancing disease in a glioblastoma patient post gross total resection. b and c show pre-operative axial and coronal views of the tumor. NovoTAL mapping was performed using pre-operative T1 postcontrast sequences in a standard manner. Head size measurements were determined on axial and coronal views (not shown). In figure b, axial tumor location was determined measuring from a reference frame drawn at the level of the scalp. Axial tumor locations measurements are shown A-P (2), R-L (3), R-midline (5), right to near tumor margin (6), right to far tumor margin (4), front to near tumor margin (8), front to far tumor margin (9). Figure c shows tumor location measurements obtained in coronal view. All measurements originate from a reference frame drawn at the level of scalp, extending inferiorly to the lower margins of temporal lobe. The coronal tumor location measurements consist of a superior to inferior measurement (2), R-L (3), right to midline (5), right to close (6) and right to far (7) tumor margins, and superior to close (8) and superior to far (9) tumor margin measures
