Quantification of Tumor Vessels in Glioblastoma Patients Using Time-of-Flight Angiography at 7 Tesla: A Feasibility Study
Figure 1
Patient with a left temporal glioblastoma.
A) contrast enhanced T1-weighted images at 3 Tesla. B) 7 Tesla ToF angiography maximum intensity projection; enlarged in C). Tumor vessels with multiple branches can clearly be identified within the glioblastoma (white arrows in C). Signal intensity in the tumor vessels is reduced compared to the regular vessels due to signal loss in the irregular and leaky tumor vessels.
