摘要:

甲状腺癌是最常见的内分泌恶性肿瘤,其发病率在全球范围内持续上升。尽管超声是检测甲状腺结节的首选成像模态,但其诊断准确性常受到低图像对比度和结节边界模糊等挑战的限制。为了解决这些问题,我们提出Nodule-DETR,一种专为超声图像中鲁棒甲状腺结节检测设计的新型检测Transformer(DETR)架构。Nodule-DETR引入了三个关键创新:多谱频域通道注意力(MSFCA)模块,利用频域分析增强低对比度结节的特征;分层特征融合(HFF)模块,用于高效的多尺度整合;以及多尺度可变形注意力(MSDA),以灵活捕捉小而不规则形状的结节。我们在临床数据集上进行了广泛的实验,结果表明Nodule-DETR实现了最先进的性能,比基线模型在mAP@0.5:0.95上提高了显著的0.149。Nodule-DETR的优越准确性突显了其在临床应用中作为计算机辅助甲状腺诊断有效工具的显著潜力。工作代码可在https://github.com/wjj1wjj/Nodule-DETR上获得。

英文摘要:

Thyroid cancer is the most common endocrine malignancy, and its incidence is rising globally. While ultrasound is the preferred imaging modality for detecting thyroid nodules, its diagnostic accuracy is often limited by challenges such as low image contrast and blurred nodule boundaries. To address these issues, we propose Nodule-DETR, a novel detection transformer (DETR) architecture designed for robust thyroid nodule detection in ultrasound images. Nodule-DETR introduces three key innovations: a Multi-Spectral Frequency-domain Channel Attention (MSFCA) module that leverages frequency analysis to enhance features of low-contrast nodules; a Hierarchical Feature Fusion (HFF) module for efficient multi-scale integration; and Multi-Scale Deformable Attention (MSDA) to flexibly capture small and irregularly shaped nodules. We conducted extensive experiments on a clinical dataset of real-world thyroid ultrasound images. The results demonstrate that Nodule-DETR achieves state-of-the-art performance, outperforming the baseline model by a significant margin of 0.149 in mAP@0.5:0.95. The superior accuracy of Nodule-DETR highlights its significant potential for clinical application as an effective tool in computer-aided thyroid diagnosis.
