肺部疾病CT评估
用于诊断和特征描述各种肺部疾病的综合胸部成像,包括间质性肺病、COPD和肺癌。

什么是 CT Lung Diseases?
肺部疾病CT成像是一种专门优化的胸部CT方案,用于评估各种肺部病理。它包括用于详细评估肺实质的高分辨率CT(HRCT)和用于更广泛评估的标准CT。
工作原理: 扫描仪在深吸气末获取肺部的薄层图像(1-2毫米)。对于HRCT,在仰卧位有时在俯卧位获取图像,以区分依赖性变化与真正病理。多平面重建允许详细评估肺部结构。
CT Lung Diseases 的常见用途
间质性肺病评估
Characterize patterns of UIP, NSIP, COP, and other ILDs; assess disease extent
COPD评估
Quantify emphysema distribution and severity; assess for bronchiectasis
肺癌筛查
Low-dose CT for high-risk individuals (smokers, age 50-80)
肺结节特征描述
Determine benign vs. malignant features; guide follow-up recommendations
感染评估
Identify pneumonia patterns, complications, and response to therapy
职业性肺病
Assess asbestos-related disease, silicosis, and other occupational exposures
优势
- ✓检测肺部异常的敏感性极高
- ✓高特异性地描述疾病模式
- ✓检测胸片上不可见的发现
- ✓引导活检和治疗规划
- ✓监测疾病进展和治疗反应
局限性
- ⚠电离辐射暴露
- ⚠某些适应症可能需要造影剂
- ⚠发现可能非特异性,需要临床相关
- ⚠偶发发现可能需要进一步评估
- ⚠不能替代组织病理学进行明确诊断
- ⚠运动伪影可能降低图像质量

相关影像方式
Chest X-ray is often the initial test but provides less detail. MRI can be used for certain indications without radiation but is less commonly used for lung parenchyma. PET-CT is valuable for characterizing suspicious nodules and staging malignancy.
X-ray
X-rays provide fast, low-cost imaging for bones, lungs, and lines/tubes placement.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
PET-CT
Combines metabolic imaging with CT anatomy for cancer staging and therapy response.
