双能CT在乳腺癌中的应用进展

Application progress of dual-energy CT in breast cancer

乳腺癌是女性最常见的恶性肿瘤,具有多种亚型及治疗方案,需早期诊断及分型。双能CT(DECT)通过使用2种不同能量水平的X射线实现物质的精确区分,经后处理生成的碘密度图可清晰显示乳腺癌病灶及内部导管扩张范围,同时生成多参数有助于乳腺癌的分子分型,以及转移、预后及疗效预测。就DECT在乳腺癌的应用现状及研究进展进行综述。

Breast cancer is the most common malignancy in women,with diverse subtypes and treatment options,making early diagnosis and classification critical.Dual-energy CT(DECT)enhances material differentiation by utilizing two distinct X-ray energy levels.The iodine density maps generated through post-processing provide clear visualization of breast cancer lesions and the extent of internal duct expansion.Additionally,DECT yields multiple parameters that aid in molecular typing,as well as in predicting metastasis,prognosis,and treatment efficacy for breast cancer.This article reviews the application and research progress of DECT in breast cancer.
