Zusammenfassung
Ziele: To evaluate the effect of arterial input selection on perfusion CT parameters of head and neck tumors. Methode: Perfusion calculations were done for 50 cases using deconvolution-based software. Peak enhancement values (PE) of the ICA and ECA were recorded. Blood flow (BF), blood volume (BV), mean transit time (MTT) and permeability surface area product (PS) were calculated using ipsilateral ECA, ipsilateral ICA and contralateral ICA as input arteries. Values were compared using matched pair t-test and Wilcoxon matched pair test as well as Pearson's correlation coefficients r. Ergebnis: High significant co…
