Figure 2: Manual seeding of arterial territories. The seeding tool allows the operator to visualize the region of tissue with a bolus arrival delay below an adjustable threshold. A-C are bolus delay maps of the same patient at increasing bolus delay thresholds. These images illustrate the propagation of the contrast bolus from proximal cerebral arteries into tissue
