Abstract：Objective To evaluate the value of CT cerebral perfusion imaging in the prognosis of patients with mild traumatic brain injury (mTBI). Methods A total of 34 patients with mTBI collected in the 908th Hospital of PLA Joint Logistics Support Force who underwent CT plain scan and perfusion imaging examination were reviewed one month after TBI using Rivermead post-concussion symptoms questionnaire (RPQ) scores as prognostic indicators. Results Abnormal cerebral perfusion was found in 30 cases (88.2%).Post-concussion syndrome(PCS) was positive in 12 cases(35.3%) (RPQ score>14). No abnormal perfusion changes were observed in 4 patients(11.8%). Of the 30 patients with abnormal perfusion, 11cases (36.7%) showed PCS, while only 1(25%) of the 4 patients without abnormal perfusion were PCS positive. The areas with abnormal perfusion were mainly manifested as focal hypoperfusion in the frontal and temporal lobes. Conclusions The hemodynamic changes in patients with mTBI canbe assessed by CT cerebral perfusion imaging, which may further help to guide the evaluation of disease severity and timely treatment of the abnormal cerebral microcirculation, thus improving the prognosis of mTBI.
