Abstract
We have noted that fast-spin-echo T2-weighted images of the cervical and thoracic regions of the spine can produce low-signal artifacts in the spinal subarachnoid space which might be misinterpreted as tumor or abnormal vascular flow voids. These are possibly related to complex cerebrospinal fluid pulsatile flow and should be recognized as artifactual by the radiologist.
摘要
我们已经注意到，脊柱颈段和胸段的快速自旋回波T2加权图像可在脊髓蛛网膜下腔产生低信号伪影，这些伪影可能被误判为肿瘤或异常血管流空信号。这些伪影可能与复杂的脑脊液搏动性血流有关，放射科医生应将其识别为伪影。
