OBJECTIVE The purpose of this study was to determine how the temporal interval between scan acquisitions influences quantitative perfusion CT vascular parameters in colorectal cancer. SUBJECTS AND METHODS Forty-five patients with colorectal adenocarcinoma prospectively underwent a 65-second single-anatomic-level perfusion CT study. Blood flow, blood volume, transit time, and permeability-surface area product for a 2-cm tumor coverage were determined with commercial software based on… CONTINUE READING
