Chest computed tomography (CT) is the modality of choice for mediastinal imaging. The high-resolution images provided by multi-detector CT result in routine visualization of normal anatomic structures, which can be confused with pathology. In addition, many mediastinal abnormalities are discovered incidentally, with a routine chest CT protocol which may be insufficient for definite diagnosis. Awareness of the spectrum of potential pitfalls of mediastinal imaging, artifacts related to flow, motion, and solutions to mitigate these problematic issues is important in accurate interpretation. The purpose of this review is to highlight and discuss potential pitfalls in the imaging of the mediastinum.
胸部计算机断层扫描（CT）是纵隔成像的首选方式。多探测器 CT 提供的高分辨率图像可常规显示正常解剖结构，但这些结构可能与病变混淆。此外，许多纵隔异常是偶然发现的，常规的胸部 CT 方案可能不足以明确诊断。了解纵隔成像中潜在陷阱的范围、与流动、运动相关的伪影以及减轻这些问题的解决方案对于准确解读非常重要。本文的目的是强调和讨论纵隔成像中的潜在陷阱。
