磁共振成像高信号被分类为脑室周围边缘、帽和不明明亮物体（UBO）。对从 590 次连续扫描中选出的 100 名急性中风和 23 名出血患者以及 59 名对照受试者进行了定量。边缘、帽和心室大小按照 0 到 3 的严重程度进行评分，并对 UBO 进行计数。结果表明，边缘在对照受试者中也很常见，并且随着年龄的增长而增加。不明的明亮物体、帽子和严重的边缘通常意味着病理，中风和出血患者的出现频率比对照受试者高得多。高血压是 UBO 和 cap 的重要危险因素，但在 rim 中，糖尿病的发病率更高。讨论了这些高信号的临床和病理意义及其与 Binswanger 病、腔隙状态和“etat cible”的关系。
Magnetic resonance imaging hyperintensities were classified as periventicular rim, caps, and unidentified bright objects (UBOs). These were quantitated in 100 acute stroke and 23 hemorrhage patients and 59 control subjects selected from 590 consecutive scans. The rims, caps, and ventricular size were rated on a scale from 0 to 3 for severity, and the UBOs were counted. The results indicated that the rim is also frequent in control subjects and increases with age. Unidentified bright objects, caps, and severe rims usually signify pathology, occurring much more frequently in patients with strokes and hemorrhages than in control subjects. Hypertension is a significant risk factor in UBOs and caps, but in rims, the incidence of diabetes is higher. The clinical and pathologic significance of these hyperintensities and their relationship to Binswanger''s disease, lacunar state, and "etat crible" is discussed.
