The use of ultrasound during surgical procedures is frequently beneficial for both demonstration and diagnosis of various pathologic conditions. In the neurosurgical suite, localization of subcortical brain tumors is easily accomplished with real-time imaging. The depth and size of the tumor are easily assessed, and the relationship of the lesion to adjacent normal structures ascertained. However, there are pitfalls that may result in diagnostic inaccuracies during the evaluation of abnormalities. These include artifacts, use of inappropriate equipment, and poor technique. These problems are illustrated and discussed.
在外科手术过程中使用超声通常有利于各种病理状况的显示和诊断。在神经外科手术室，通过实时成像可轻松实现皮质下脑肿瘤的定位。肿瘤的深度和大小易于评估，并且可以确定病变与相邻正常结构的关系。然而，在评估异常情况时可能存在导致诊断不准确的陷阱。这些包括伪像、使用不适当的设备以及技术欠佳。本文对这些问题进行了说明和讨论。
