- Effect of contrast leakage on the detection of abnormal brain tumor vasculature in high-grade gliomaPeter S LaViolette
Department of Radiology, Medical College of Wisconsin, 8701 Watertown Plank Road, Milwaukee, WI, 53226, USA
J Neurooncol 116:543-9. 2014..Contrast leakage results in large signal variance classified as a separate component by the ICA algorithm. The use of a second dose mitigates the effect and allows measurement of AVOL within enhancement. ..
