Computed Tomography

4.4K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

科学领域:

  • 胸部外科手术 胸部外科手术
  • 手术瘤学手术瘤学
  • 诊断成像诊断成像的使用

背景情况:

  • 胸腔镜分片切除术是小型外围肺结节的标准.
  • 术前成像影响手术规划和结果.

研究的目的:

  • 为了比较手术前的三维 (3D) 重建计算机断层扫描 (CT) 与标准胸部CT在小外周肺结节的胸腔镜分片切除中的疗效.
  • 评估对手术时间和术后结果的影响.

主要方法:

  • 一个多中心随机受控试验 (DRIVATS研究) 涉及191名患者.
  • 患者随机分配到3D重建CT或标准胸部CT在胸腔镜切除前.
  • 主要终点:手术时间;次要终点:术后并发症,失血,手术事故.

主要成果:

  • 在3D重建CT组 (100分钟) 和标准胸部CT组 (100分钟) 之间,手术时间没有显著差异.
  • 在两组之间,术后并发症和其他术后结果的发病率相似.
  • 在标准的胸部CT组中,只有一个手术期间的并发症发生.

结论:

  • 在患有小外周肺结节的患者中,手术前的3D重建CT可用于胸腔镜分片切除.
  • 与标准胸部CT相比,3D重建CT没有在减少手术时间或改善术后结果方面提供显著的优势.
