Preoperative Quantitative MR Tractography Compared with Visual Tract Evaluation in Patients with Neuropathologically Confirmed Gliomas Grades II and III: A Prospective Cohort Study

Figure 3

Tractography of segment 2 of the cingulum in two different patients (patient number 14 and patient number 25). ((a)-(b)) Patient with an astrocytoma grade III. (a) 3D-tractography of segment 2 of the cingulum overlaid on T2-FLAIR image shows tumor infiltrating the area of the tract segment. ROIs number two and three in yellow. (b) 3D-tractography in the same patient, segment two of the cingulum overlaid on 2D FA-color map. ((c)-(d)) Patient with an oligodendroglioma grade II. (c) 3D-tractography of segment 2 of the cingulum overlaid on T2-FLAIR image shows tumor dislocation of the tract segment. ROIs number two and three in yellow. (d) 3D-tractography in the same patient, segment two of the cingulum overlaid on 2D FA-color map.
