Abstract

Abstract: In order to explore the significance of CT enhanced scanning parameters in patients with hemorrhagic transformation (HT) after acute cerebral infarction (ACI), 200 patients with ACI were divided into bleeding group (n=84) and non bleeding group (n=116) according to whether they had HT. The influencing factors of HT after ACI and the correlation between CT enhanced scanning parameters and NIHSS score were analyzed. The diagnostic value of CT enhanced scanning parameters on HT after ACI was evaluated, and the prognosis was observed. It was found that age, infarct area, NIHSS score, ΔH value, ΔT value and ΔS value were the influencing factors of HT after ACI (P<0.05), and the parameters of CT enhanced scanning ΔH value, ΔT value, ΔS value and infarct area NIHSS score was positively correlated (P<0.05). The AUC of CT enhanced scanning parameters combined with HT after ACI is 0.896, which has a certain diagnostic efficiency, and the 90 day mortality of positive patients is higher than that of negative patients (P<0.05). Therefore, CT enhanced scanning parameters can early diagnose HT after ACI and help to estimate the prognosis of patients.
