This study was designed to evaluate the clinical accuracy of multiplanar reconstructions and three-dimensional shaded surface displays compared with conventional transaxial computed tomography, bronchoscopy, and surgical pathologic findings.
Transaxial computed tomographic images, two-dimensional nonstandard multiplanar reconstruction images, and three-dimensional images obtained from patients with tracheobronchial disease were prospectively evaluated for the relationship to adjacent structures, lesion characterization, and surgical anatomic correlation before invasive procedures.
Compared with conventional transaxial computed tomographic images, multiplanar reconstructions and three-dimensional shaded surface displays provided a correlative map of bronchoscopic and surgical anatomy in patients with benign and malignant tracheobronchial pathology. The longitudinal extent of abnormalities are better demonstrated on the multiplanar reconstruction and three-dimensional images, whereas the transverse extent of disease and relationships to adjacent structures were better shown on axial computed tomographic sections.
Three-dimensional and multiplanar two-dimensional images are additive to transaxial computed tomography for evaluation of diseases involving the central airways. They are beneficial for planning invasive procedures. More importantly, they provide consistent, highly accurate measurements for routine follow-up and for future clinical trials.
本研究旨在评估多平面重建和三维表面阴影显示与传统横轴位计算机断层扫描、支气管镜检查及手术病理结果相比的临床准确性。
前瞻性评估气管支气管疾病患者的横轴位计算机断层扫描图像、二维非标准多平面重建图像及三维图像，以确定其与相邻结构的关系、病变特征及侵入性操作前的手术解剖相关性。
与传统横轴位计算机断层扫描图像相比，多平面重建和三维表面阴影显示为良性和恶性气管支气管病变患者提供了支气管镜和手术解剖的相关图谱。多平面重建和三维图像能更好地显示异常的纵向范围，而横轴位计算机断层扫描切片能更好地显示疾病的横向范围及与相邻结构的关系。
三维和多平面二维图像对横轴位计算机断层扫描在评估中央气道疾病方面具有补充作用。它们有助于规划侵入性操作。更重要的是，它们为常规随访和未来临床试验提供了一致、高度准确的测量结果。
