在轴向快速MR图像上通常观察到覆盖在颅底处的含气结构上的脑中的信号丢失区域。这种效应的性质,它可以模仿脑出血的外观,在一个幻影研究和正常志愿者进行了调查。发现信号损失的幅度与扫描平面距含气结构的距离成反比,而与回波时间成正比。
Areas of signal loss in brain overlying air-containing structures at the skull base are commonly observed on axial fast MR images. The nature of this effect, which can mimic the appearance of cerebral hemorrhage, is investigated in a phantom study and in a normal volunteer. The magnitude of the signal loss is found to be inversely related to the distance of the scanning plane from the air-containing structure and directly related to the echo time.
