亚厘米肺结节CT密度测量与鉴别诊断价值
|
Abstract:
在临床医疗实践与研究领域，对直径 ≤ 10 mm的亚厘米肺结节定性诊断始终是一个挑战性的焦点。影像学鉴别诊断主要依据结节类型及形态学特征，结节密度精准测量对结节类型的分类及良恶性评判具有重要意义。本文就密度测量的重要性及影响因素、CT图像重建算法对亚厘米肺结节的分辨能力、以及良恶性鉴别诊断作用进行综述。另外，简要讨论CT重建算法对肺结节AI密度检测、结节分类、良恶性评判的影响。
In the field of clinical practice and research, the qualitative diagnosis of sub-centimeter pulmonary nodules with diameter ≤ 10 mm is always a challenging focus. The imaging differential diagnosis of nodules is mainly based on the type and morphological characteristics of nodules. Accurate meas-urement of nodule density is of great significance for the classification of nodules and the evaluation of benign and malignant nodules. This article reviews the importance and influencing factors of density measurement, the resolution ability of CT image reconstruction algorithms in sub-centimeter pulmonary nodules, and the role of benign and malignant differential diagnosis. In addition, the effects of CT reconstruction algorithms on AI density detection, nodule classification, and benign and malignant evaluation of pulmonary nodules were briefly discussed.
