Abstract

Clinical application value of CT perfusion (CTP) imaging in the treatment of acute ischemic stroke (AIS) thrombolytic therapy was investigated. Retrospective analysis of 185 suspected AIS patients in Liaocheng Brain Hospital from April 2012 to December 2017 were involved. We observed the non-contrast CT (NCCT) and CTP in the diagnosis of AIS patients, and recorded as well as compared CTP para- meters of AIS patients. The National Institute of Health Stroke Scale (NIHSS) rating was conducted, and the correlation between the prognosis of NIHSS scores and CTP parameters was investigated. A total of 177 patients were diagnosed with AIS. The sensitivity levels of CTP examination for diagnosis of AIS patients was significantly higher than that of the NCCT examination (P<0.050). The diagnostic compliance rates of CTP examination was significantly higher than that of the NCCT examination (P<0.050). The cerebral blood volume (CBV) in the abnormal perfusion area was significantly lower than that in the mirror side zone (t=21.160, P<0.001). The prognostic NIHSS score was negatively correlated with CBV in patients with thrombolytic therapy (r=‑0.912, P<0.001). The cerebral blood flow (CBF) in the abnormal perfusion zone was significantly lower than that in the mirror side zone (t=19.170, P<0.001). The prognosis of patients with thrombolytic therapy was negatively correlated with CBF (r=‑0.915, P<0.001). The mean transit time (MTT) in the abnormal perfusion zone was higher than that in the mirror side zone (t=13.480, P<0.001). NIHSS scores were obtained 3 months after thrombolytic therapy and found that the prognostic NIHSS scores were positively correlated with MTT (r=0.887, P<0.001). The results indicated that brain CTP has a high diagnostic value for intravenous thrombolytic therapy in AIS and there was a significant correlation between the prognosis scores of patients. Thus, it is worthy of being promoted in the clinical diagnosis and treatment of AIS patients.
