Abstract Objective To compare the clinical value of CT and MRI in the diagnosis of patients with acute craniocerebral injury.Methods Sixty-five patients with acute craniocerebral injury admitted to our hospital from December 2017 to June 2019 were selected as the subjects. All patients were given CT and MRI to analyze the imaging findings. The detection rate of acute craniocerebral injury and hematoma thickness detection coincidence rate were compared between the two examinations. The apparent diffusion coefficient (ADC) level at mild and severe region of interest (ROI) was assessed using MRI. Results The total detection rate of acute craniocerebral injury by MRI was 89.23%, higher than that of CT accounting for 66.15%. The detection rates of MRI on subarachnoid hemorrhage and skull fracture were lower than those of CT, and the detection rates of MRI on cerebral contusion, deep contusion, middle and posterior fossa injury, gray matter junctional zone injury and corpus callosum injury were higher than those of CT, with statistical significance (P＜0.05). The coincidence rate of MRI on hematoma thickness was 87.69%, higher than that of CT accounting for 64.62%,with statistical significance(P＜0.05).There was no significant difference in the detection rate of subdural hematoma between the two methods (P＞0.05). The level of ADC in the knee of hydrazine callosum and the back of cerebral foot in the patients with moderate and severe injury was higher than that in the patients with mild injury, and the level of ADC in the front limb of internal capsule and the right side of cerebral foot was lower than that in the patients with mild injury, with statistical significance (P＜0.05). Conclusion Compared with conventional CT, MRI is of high value for the diagnosis of acute craniocerebral injury. The detection rates of lesions and special affected parts are high.
