目的确定原位导管癌(DCIS)及其亚型的DWI表现特点。方法回顾性分析69例女性的74个原位导管癌的DWI影像(1.5T;b=0、600s/mm2)。每个病变的特征由定性的DWI强度、定量的DWI病变正常组织信噪比(CNR)以及定量的ADC值确定,检出率根据每一参数事前设定的域值算
Objective To determine the characteristics of DWI in situ ductal carcinoma (DCIS) and its subtypes. Methods We retrospectively analyzed DWI images of 74 ductal carcinoma in situ in 69 women (1.5T; b = 0,600s / mm2). The characteristics of each lesion were determined by qualitative DWI intensity, quantified normal tissue signal-to-noise ratio (CNR) of DWI lesions, and quantitative ADC values. The detection rate was calculated based on the pre-set threshold values for each parameter
