Head scans in 27 infants were done to compare the value of ultrasonography and computed tomography (CT) in the evaluation of macrocrania and encephalocele. Ultrasonography and CT correlated well with regard to anatomical information, especially in the assessment of the lateral and third ventricles. However, unlike CT, ultrasonography uses no ionizing radiation, is less expensive, eliminates sedation, and reduces artifacts due to motion and metal clips. In conjunction with an initial CT examination, ultrasonography is useful for serial evaluation of the lateral and third ventricles. It can also be helpful in assessing extraventricular fluid collections and suspected encephaloceles.
对27名婴儿进行头部扫描，以比较超声检查和计算机断层扫描（CT）在评估巨颅症和脑膨出方面的价值。超声检查和CT在解剖学信息方面相关性良好，尤其是在评估侧脑室和第三脑室时。然而，与CT不同的是，超声检查不使用电离辐射，成本较低，无需镇静，并且减少了因运动和金属夹引起的伪影。与初始CT检查相结合，超声检查有助于对侧脑室和第三脑室进行系列评估。它还有助于评估脑室外积液和疑似脑膨出。
