Correlation analysis of the prognosis evaluated by SWI with CBV in the early acute cerebral infarction patients

Objective: To detect the susceptibility weighted imaging(SWI) of prominent vessel(PV), investigate the correlation of clinical prognosis with cerebral blood volume(CBV) in early acute cerebral infarction patients, and analyze the clinical significance of PV. Methods: The imaging of the head in 22 patients with acute cerebral infarction were examined within 3 days of disease. The imaging of PV in SWI were graded according to the classification of anastomosis vessels of cortex and leptomeningeal. Two lays with obvious PV in lesions were set as the region of interesting(ROI) area. The focal mirror of 3 points in the lesion center and around in ROI area were measured, the CBV value of which was recorded for calculating the average value of parameter in the healthy and disease side. The scores of national institutes of health stroke scale(NIHSS) at admission and after 14 days of disease, and modified Rankin Scale(mRS) after 90 days of disease were analyzed. Results: The PV grading of patient was positive correlation with the CBV of disease side(P<0.05). The PV grading of patient was not correlation with the NIHSS scores at onset and after 14 days of disease, and mRS score after 90 days of disease(P>0.05). Conclusions: The phenomenon and grading of PV in SWI can reflect the cerebral blood volume changes of lesion side in acute cerebral infarction patients.
