摘　　要：对比增强能谱乳腺X线摄影(Contrast Enhancement Spectral Mammography,CESM)是在传统乳腺X线摄影的基础上使用双能量减影和对比增强技术来显示乳腺钙化、腺体结构及病灶内血供等情况。CESM量化方法能更准确地评价乳腺疾病,与传统乳腺X线摄影相比,其对乳腺癌诊断、分子分型鉴别、新辅助化疗疗效评估等多方面具有较大优势。目前量化方法存在多种测量方案,尚无统一的标准指南。本文对CESM量化方法的临床应用及研究现状进行综述,旨在探寻不同计算方案之间的优劣势,为辅助临床诊断及预后提供量化依据。Contrast enhancement spectral mammography(CESM)is the use of dual-energy subtraction and contrast enhancement techniques on the basis of traditional mammography to display breast calcification,glandular structure,and intrafocal blood supply.Compared to mammography,quantification method of CESM is emerging as an objective and accurate to diagnose abnormal breasts,to distinguish molecular subtypes of breast cancer and to evaluate response to neoadjuvant chemotherapy.At present,there are many measurement schemes for quantitative methods,and there is no unified standard guide.This paper reviewed the clinical application and research status of CESM quantitative method,aiming to explore the advantages and disadvantages of different computational schemes and provide quantitative basis for clinical diagnosis and prognosis.
