-weighted angiography (ESWAN) sequence in the diagnosis of cerebral infarction accompanying cerebral microbleeds. Methods Imaging data were collected from 55 patients admitted to our hospital from
March to October in 2011 and diagnosed with cerebral infarction. The site
number
and manifestations of cerebral microbleeds on ESWAN were recorded. Results The proportion of detected cerebral microbleeds was 52.73% (29/55)
29.09% (16/55)
and 8.82% (3/34) respectively on ESWAN
conventional MR sequences (Chi square=6.36
P<0.05)
and CT scanning (Chi square=29.79
P<0.01). In the ESWAN images
there were 51.72% patients (15/29) manifesting as absence of small round signals only outside of the infarct
37.93% (11/29) as absence of small sheet and strip signals only in the infarct
and the left 10.34% (3/29) as above-mentioned signals in and outside of the infarct. Of the 29 patients with cerebral microbleeds detected in and outside the infarct
37.93% (11/29) were diagnosed as lacunar infarction with 81.82% (9/11) of them diagnosed as cerebral microbleeds outside the infarct
48.28% (14/29) were diagnosed as massive cerebral infarction with 71.43% (10/14) of them diagnosed as cerebral microbleeds inside the infarct. The incidence of cerebral microbleeds was significantly different in different stages of cerebral infarction (P<0.05). Cerebral microbleeds were more common when encephalomalacia foci were found following cerebral infarction (P<0.05). Conclusion The occurrence of cerebral microbleeds is closely related with the severity of vascular injury and ESWAN is of great value for the diagnosis of cerebral infarction accompanying cerebral microbleeds.
