The benefits of multi-detector row CT (MDCT) relative to single-detector row helical CT are considerable. Multi-detector row CT allows shorter acquisition times, greater coverage, and superior image resolution. These factors substantially increase the diagnostic accuracy of the examination. Three-dimensional (3D) volume data from MDCT provides various unique applications on thoracic diseases. These includes isotropic viewings, use of multiplanar reformation (MPR), maximum and minimum intensity projections (MIP and minIP), and volume rendering performed from external and internal perspectives allowing the user to "fly around" and "fly through" the structures. Recent advances in 3D volume rendering put real-time, interactive virtual reality guidance of the procedures such as bronchoscopy and surgery into practice.
多排探测器CT（MDCT）相对于单排探测器螺旋CT的优势相当显著。多排探测器CT能够实现更短的扫描时间、更大的覆盖范围以及更高的图像分辨率。这些因素显著提高了检查的诊断准确性。MDCT的三维（3D）容积数据为胸部疾病提供了各种独特的应用。这些应用包括各向同性观察、多平面重建（MPR）、最大和最小密度投影（MIP和minIP），以及从外部和内部视角进行的容积再现，允许用户“环绕”和“穿过”这些结构。3D容积再现技术的最新进展使支气管镜检查和手术等操作的实时、交互式虚拟现实引导成为现实。
