Abstract
To assess a magnetic resonance (MR) imaging method for depicting small veins in the brain, a three-dimensional, long echo time, gradient-echo sequence that depended on the paramagnetic property of deoxyhemoglobin was used. Veins with diameters smaller than a pixel were depicted. This MR imaging method is easy to implement and may prove helpful in the evaluation of venous diseases.
摘要
为评估一种用于描绘脑内小静脉的磁共振（MR）成像方法，采用了一种依赖脱氧血红蛋白顺磁特性的三维、长回波时间梯度回波序列。直径小于一个像素的静脉得以描绘。这种MR成像方法易于实施，可能在静脉疾病评估中证明有用。
