Facing Contrast-Enhancing Gliomas: Perfusion MRI in Grade III and Grade IV Gliomas according to Tumor Area

Figure 1

Scatter-plot diagram representing rCBV values according to grade and tumor area. Circles represent grade III, squares grade IV. Green color represents rCBV values measured in CBV map; blue color represents rCBV values measured in the nonenhancing tumor (Non-CE); orange color represents rCBV values measured in enhancing area (CE). Lines correspond to mean value and error bars to standard error of the mean. Only rCBV values measured in the high perfusion area in CBV map showed significant difference between grade III and grade IV gliomas.
