| 摘 要： | 目的：探讨容积数据高分辨力CT重建（VHRCT）对肺部磨玻璃密度影的临床诊断价值。方法：对27例肺部弥漫性磨玻璃密度灶和5例局限性磨玻璃密度灶患者进行MSCT和HRCT扫描及VHRCT图像重建,对HRCT及VHRCT图像质量进行分级评分（3级评分法）。结果：27例肺部弥漫性磨玻璃密度灶患者的VHRCT和HRCT图像评分结果分别是52分和49分,2种图像质量的差异无统计学意义（Z=-1.00,P=0.317）;5例局限性磨玻璃密度患者的VHRCT和HRCT图像评分结果分别1分和0分,2种图像质量的差异无统计学意义（Z=-1.00,P=0.317）。结论：VHRCT重建图像评价肺部磨玻璃密度影的价值与HRCT扫描图像相当,VHRCT重建图像为观察肺部磨玻璃密度影提供了一种简单易行的方法。

| Abstract: | Objective:To evaluate the clinical application of thin-reconstruction of volumetric data with a high-resolution algorithm in pulmonary ground-glass opacity.Methods:27 patients with diffuse pulmonary ground-glass opacity and 5 patients with focal pulmonary ground-glass opacity underwent MSCT and HRCT scans and volumetric HRCT reconstructions.Conventional HRCT scans and volumetric HRCT images were rated for image quality and diagnostic value in pulmonary ground-glass opacity.Results:In 27 patients with diffus... |
