Abstract
Introduction: We compared pancreatic blood flow (PBF) measured by perfusion CT with deconvolution method and Laser Doppler Flow (LDF) to determine whether uncollected contrast material from the pancreas affects measurement of perfusion CT, using porcine pancreatitis model (n = 7). Materials and Methods: The pancreas was divided into head and tail. We arranged that PBF of tail was circulated by single input/output vessel. Ischemic pancreatitis was induced to tail, shutting off input/output vessel for 30 min. PBF was measured both by perfusion CT with deconvolution method and LDF, during the overall course. We calculated uncollected ratio of contrast material, assuming area-under-curve differences between the input and output vessels correspond to uncollected. Results: tail PBF measured by perfusion CT with deconvolution was significantly correlated with LDF, despite of pancreatitis (P < 0.05). The uncollected ratio was 19 %. Discussion: Although the uncollected ratio was not few, result of perfusion CT was significantly related with LDF.
