Helical (spiral) CT of the liver consistently results in high quality scans as a result of the ability to image the liver in a single breath hold. Lesion detection is aided by scanning during the peak of hepatic enhancement, by the lack of respiratory misregistration, and by obtaining overlapping axial reconstructions. Because of these advantages, helical (spiral) CT is the preferred scanning mode for evaluation of hepatic disease.
由于能够在一次屏气过程中对肝脏进行成像，肝脏螺旋CT始终能产生高质量的扫描图像。在肝脏强化高峰期进行扫描、不存在呼吸配准误差以及获取重叠的轴向重建图像，有助于病变的检测。由于这些优势，螺旋CT是评估肝脏疾病的首选扫描方式。
