연구목적 뇌 자기공명영상에서 발견된 백질변성의 소견은 인지기능 저하와 관련이 있다고 알려져 있지만 이의 중요성은 명확하게 밝혀진 바 없다. 본 연구는 뇌 자기공명영상에서 관찰되는 백질변성이 섬망의 심각도나 경과에 미치는 영향을 규명하기 위해 시행되었다. 방 법 섬망 삽화 전후에 뇌 자기공명영상이 촬영된 42명의 섬망 환자에 대하여 반정량적인 시각평가척도를 이용하여 뇌실주위 백질 고강도신호와 심부백질 고강도신호를 평가하였다. 이 고강도신호의 등급과 섬망평가척도 점수 간의 상관 관계를 분석하였고, 등급이 높은 군과 낮은 군으로 나누어 군에 따른 섬망평가척도 점수의 변화 차이를 추가로 분석하였다. 결 과 후두엽의 심부백질 고강도신호 등급과 섬망평가척도의 총점, 심각도 항목, 인지 항목 및 비인지 항목의 합과 양의 상관관계를 보였다. 또한 첫 평가와 추적 평가를 비교하였을 때 뇌실주위 백질 고강도신호의 등급이 낮은 군이 높은 군보다 섬망평가척도의 인지 항목 점수가 유의미한 경사로 가파르게 감소하였다. 결 론 뇌 백질 고강도신호 등급에 따라 섬망의 심각도와 호전 속도에 차이를 보이는 것은 뇌 백질변성이 대뇌 기능 연결성의 단절을 초래하여 유발한 결과로 볼 수 있다. 본 연구는 뇌 자기공명영상에서 발견된 고강도신호의 등급의 평가를 통해 섬망의 심각도와 경과를 예측해 볼 가능성이 있다는 점에서 임상적으로 유용할 수 있다.

Objective : Leukoaraiosis (LA) has been suggested to be related to the poor outcome or the occurrence of symptomatic intracerebral hemorrhage (sICH) after acute ischemic stroke. We retrospectively investigated the influences of LA on long-term outcome and the occurrence of sICH after thrombolysis in acute ischemic stroke (AIS). Methods : In this study, we recruited 164 patients with AIS and magnetic resonance image (MRI)-detected thrombolysis. The presence and extent of LA were assessed using the Fazekas grading system. The National Institutes of Health Stroke Scale score was used to assess the baseline measure of neurologic severity, and the modified Rankin Scale score assessment was used up to 1 year after thrombolysis. Results : Of 164 subjects, 56 (34.2%) showed LA on MRI. Compared to the 108 patients without LA, the patients with LA were of much older age (p<0.01), had a higher prevalence of hypertension (p<0.01), and had a much poorer outcome at 90 days (p=0.05) and 1 yr (p=0.01) after thrombolysis. There were no significant differences in sICH between patients with and without LA on MRI. In univariate analysis for the occurrence of poor outcome at 90 days after thrombolysis, the size of ischemic lesion on diffusion weighted images (DWI), [odds ratio (OR), 1.03; 95% confidence interval (95% CI), 1.01-1.04; p<0.01], recanalization (OR, 0.03; 95% CI, 0.01-0.10; p<0.01), sICH (OR, 12.2; 95% CI, 1.54-95.8), neurologic severity (OR, 1.17; 95% CI, 1.09-1.25; p<0.01), blood glucose level (OR, 1.01; 95% CI, 1.00-1.02; p=0.03), and the presence of LA on MRI (OR, 2.01; 95% CI, 1.04-3.01; p=0.04) were statistically significant. In multivariate analysis, neurologic severity (OR, 1.14; 95% CI, 1.04-1.24; p<0.01), recanalization (OR, 0.03; 95% CI, 0.01-0.11; p<0.01), lesion size on DWI (OR, 1.02; 95% CI, 1.01-1.03; p=0.02), serum glucose level (OR, 1.01; 95% CI; 1.01-1.02; p=0.03), and the presence of LA on MRI (OR, 3.2; 95% CI, 1.22-8.48; p<0.01) showed statistically significant differences. These trends persisted up to 1 yr after thrombolysis. Conclusion : In this study, we demonstrated that the presence of LA on MRI might be related to poor outcome after use of intravenous tissue plasminogen activator in AIS.

Objective : We investigate risk factors of cerebral microbleeds[MBs] and their relation to concomitant magnetic resonance[MR] findings in intracerebral hemorrhages[ICHs] patients. Methods : We studied 100 consecutive patients with primary ICH over a 1-year period. These patients underwent brain MR images using 3.0-T scanners within the first week of the hemorrhage. MBs and old hematomas were located and counted by using $T2^*-weighted$ gradient-echo MR imaging. We also counted lacunes and graded white matter and periventricular hyperintensity on T1- and T2-weighted spin-echo sequences. The association between MBs and vascular risk factors and MR abnormalities were analyzed. Results : MBs were seen in 77 of ICH patients, and their number ranged from 1 to 65 lesions [mean 11, median 6]. The locations of MBs were subcortex-cortex [40.6%], basal ganglia [26.7%], thalamus [14.1 %], brain stem [12.5%], and cerebellum [9.1 %]. Analysis of clinical data revealed that age, hypertension, history of stroke, and duration of hypertension were frequently associated with MBs. The incidence of lacunes, old hematomas, and advanced leukoaraiosis was significantly higher in the MBs group, compared with the patients without MBs. Conclusion : MBs are frequently observed in ICH patients with advancing age, chronic hypertension, and previous hemorrhagic stroke, and are also closely related with morphological signs of occlusive type microangiopathy, such as lacunar infarct and severe leukoaraiosis.

It is common to find cerebral infarct and hemorrhage without definite neurologic signs but with lesions on neuroimaging. These lesions are called silent lacunar infarct and cerebral microbleed. Silent lacunar infarct are frequently seen in the elderly and are associated with clinically apparent stroke and vascular dementia. Known stroke risk factors, such as hypertension, diabetes mellitus, smoking, hypercholesterolemia and heart problems may increase the risk of silent lacunar infarct. Metabolic syndrome, homocysteinemia, renal failure and intima media thickness(IMT) are also other risk factors of the silent lacunar infarct. Cerebral microbleed, lacunar infarct and intracerebral hemorrhage(ICH) have similar pathology and pathogenesis. So, cerebral microbleed are coexisted with lacunar infarct, leukoaraiosis, hypertensive ICH and vascular dementia. Cerebral microbleed are associated with volume and recurrence of ICH. Also cerebral microbleed may reflect baseline status of blood brain barrior disruption. Silent lacunar infarct and cerebral microbleed are very important to clinical management, but in the aspect of insurance medicine and independent medical examiners, these lesions are not subject of evaluation for handicap.

Objective : The authors studied the risk factors of silent cerebral microbleeds (MBs) and old hematomas (OHs) and their association with concurrent magnetic resonance (MR) imaging findings in the patients of intracerebral hemorrhages (ICHs). Methods : From April 2002 to June 2007, we retrospectively studied 234 patients of primary hemorrhagic stroke. All patients were evaluated with computed tomography (CT) and 3.0-tesla MR imaging studies within the first week of admission. MBs and OHs were assessed by using $T2^{\ast}$-weighted gradient-echo (GRE) MR imaging. The patients were divided into 2 groups, depending on whether or not they had two GRE lesions of chronic hemorrhages. A correlation between MBs and OHs lesions were also statistically tested. Lacunes and white matter and periventricular hyperintensities (WMHs, PVHs) were checked by T1- and T2-weighted spin-echo and fluid attenuated inversion recovery sequences. Variables on the clinical and laboratory data and MR imaging abnormalities were compared between both groups with or without MBs and OHs. Results : MBs were observed in 186 (79.5%) patients and a total of 46 OHs were detected in 45 (19.2%) patients. MBs (39.6%), OHs (80.4%), and ICHs (69.7%) were most commonly located in the ganglionic/thalamic region. Both MBs and OHs groups were more frequently related to chronic hypertension and advanced WMHs and PVHs. The prevalence and number of MBs were more closely associated with OHs groups than non-OH patients. Conclusion : This study clearly demonstrated the presence of MBs and OHs and their correlation with hypertension and cerebral white matter microangiopathy in the ICHs patients. Topographic correlation between the three lesions (MBs, OHs, and ICHs) was also noted in the deep thalamo-basal location.
