Abstract

OBJECTIVES

To compare the image quality of the lungs between ultra-high-resolution CT (U-HRCT) and conventional area detector CT (AD-CT) images.

METHODS

Image data of slit phantoms (0.35, 0.30, and 0.15 mm) and 11 cadaveric human lungs were acquired by both U-HRCT and AD-CT devices. U-HRCT images were obtained with three acquisition modes: normal mode (U-HRCT: 896 channels, 0.5 mm × 80 rows; 512 matrix), super-high-resolution mode (U-HRCT: 1792 channels, 0.25 mm × 160 rows; 1024 matrix), and volume mode (U-HRCT: non-helical acquisition with U-HRCT). AD-CT images were obtained with the same conditions as U-HRCT. Three independent observers scored normal anatomical structures (vessels and bronchi), abnormal CT findings (faint nodules, solid nodules, ground-glass opacity, consolidation, emphysema, interlobular septal thickening, intralobular reticular opacities, bronchovascular bundle thickening, bronchiectasis, and honeycombing), noise, artifacts, and overall image quality on a 3-point scale (1 = worst, 2 = equal, 3 = best) compared with U-HRCT. Noise values were calculated quantitatively.

RESULTS

U-HRCT could depict a 0.15-mm slit. Both U-HRCT and U-HRCT significantly improved visualization of normal anatomical structures and abnormal CT findings, except for intralobular reticular opacities and reduced artifacts, compared with AD-CT (p < 0.014). Visually, U-HRCT has less noise than U-HRCT and AD-CT (p < 0.00001). Quantitative noise values were significantly higher in the following order: U-HRCT (mean, 30.41), U-HRCT (26.84), AD-CT (16.03), and U-HRCT (15.14) (p < 0.0001). U-HRCT and U-HRCT resulted in significantly higher overall image quality than AD-CT and were almost equal to U-HRCT (p < 0.0001).

CONCLUSIONS

Both U-HRCT and U-HRCT can provide higher image quality than AD-CT, while U-HRCT was less noisy than U-HRCT.

KEY POINTS

• Ultra-high-resolution CT (U-HRCT) can improve spatial resolution. • U-HRCT can reduce streak and dark band artifacts. • U-HRCT can provide higher image quality than conventional area detector CT. • In U-HRCT, the volume mode is less noisy than the super-high-resolution mode. • U-HRCT may provide more detailed information about the lung anatomy and pathology.

摘要

目的

比较超高分辨率 CT（U-HRCT）和常规扇区探测器 CT（AD-CT）图像的肺部图像质量。

方法

使用 U-HRCT 和 AD-CT 设备分别获取狭缝体模（0.35、0.30 和 0.15mm）和 11 例人体肺标本的图像数据。U-HRCT 图像采用三种采集模式获得：常规模式（U-HRCT：896 通道，0.5mm×80 排；512 矩阵）、超高分辨率模式（U-HRCT：1792 通道，0.25mm×160 排；1024 矩阵）和容积模式（非螺旋 U-HRCT）。AD-CT 图像采用与 U-HRCT 相同的条件采集。三名独立观察者采用 3 分制（1=最差，2=相等，3=最佳）对正常解剖结构（血管和支气管）、异常 CT 表现（淡结节、实性结节、磨玻璃影、实变、肺气肿、小叶间隔增厚、小叶内网状影、血管支气管束增厚、支气管扩张和蜂窝肺）、噪声、伪影和整体图像质量进行评分，并与 U-HRCT 进行比较。定量计算噪声值。

结果

U-HRCT 可显示 0.15mm 的狭缝。与 AD-CT 相比，U-HRCT 和 U-HRCT 均显著改善了正常解剖结构和异常 CT 表现的可视化效果，除小叶内网状影和伪影减少外（p＜0.014）。视觉上，U-HRCT 的噪声小于 U-HRCT 和 AD-CT（p＜0.00001）。定量噪声值依次为：U-HRCT（均值，30.41）、U-HRCT（26.84）、AD-CT（16.03）和 U-HRCT（15.14）（p＜0.0001）。U-HRCT 和 U-HRCT 的整体图像质量明显高于 AD-CT，与 U-HRCT 几乎相等（p＜0.0001）。

结论

U-HRCT 和 U-HRCT 均可提供优于 AD-CT 的图像质量，而 U-HRCT 的噪声小于 U-HRCT。

关键点

  1. 超高分辨率 CT（U-HRCT）可提高空间分辨率。

  2. U-HRCT 可减少条纹和暗带伪影。

  3. U-HRCT 可提供优于常规扇区探测器 CT 的图像质量。

  4. U-HRCT 容积模式的噪声小于超高分辨率模式。

  5. U-HRCT 可能提供更详细的肺部解剖和病理信息。
