Abstract:

To explore the correlation between the imaging anatomical characteristics of acute cerebral infarction patients based on magnetic resonance diffusion-weighted imaging (MR-DWI) and the recurrence of patients. This study retrospectively analyzed the clinical data and MR data of 211 patients with acute cerebral infarction confirmed clinically and meeting the inclusion and exclusion criteria. The number of lesions and the number of involved cerebral blood supply areas were counted, and the total area of infarction and the area of subcutaneous fat were measured. The correlation between the recurrence and non-recurrence of patients within one year and the above data was analyzed. The results showed that there was a statistically significant difference in the number of lesions and the number of involved blood supply areas between the recurrence and non-recurrence groups of acute cerebral infarction (p < 0.05); there was no statistically significant difference in the total area of lesions on axial images and the area of subcutaneous fat between the two groups (p > 0.05). Therefore, it is concluded that the number of lesions and the number of involved cerebral blood supply areas on MR-DWI images of acute cerebral infarction patients are the main influencing factors for recurrence within one year. This study can provide imaging evidence for clinicians to conduct individualized treatment and prognosis evaluation of patients.
