Time to drain ct perfusion
WebCT and MRI perfusion scanning were performed on days 14, 17, 21, 25, and 28 after tumor implantation. CT perfusion parameters were perfusion, peak enhanced increment, transit time peak, and blood volume, and MRI perfusion parameters were wash in rate, wash out rate, maximum enhancement rate, and transit time peak. WebTime to drain showed the highest agreement and therefore might be an interesting parameter to define tissue at risk. Whole-brain CT perfusion: reliability and reproducibility …
