Invasive lobular carcinoma (ILC) is the second most common kind of breast cancer. Diffusion weighted imaging (DWI) and positron emission tomography/computed tomography (PET/CT) are functional modalities for presenting the biological characteristics of breast cancer. The purpose of this article is to study the relationship between DWI or PET/CT and ILC's prognostic factors. The relationship between the apparent diffusion coefficient (ADC) values, standard uptake value (SUV)max and prognostic factors of ILC were statistically evaluated. The ADC values were lower in mass types of ILC. SUVmax was statistically higher in grade 3 and 4 background parenchymal enhancement and positive lymph node metastasis. ADC values of DWI and SUVmax of PET/CT can be helpful in the prediction of the prognosis of ILC.
浸润性小叶癌（ILC）是第二常见的乳腺癌类型。扩散加权成像（DWI）和正电子发射断层扫描/计算机断层扫描（PET/CT）是用于呈现乳腺癌生物学特征的功能成像方式。本文旨在研究DWI或PET/CT与ILC预后因素之间的关系。对ILC的表观扩散系数（ADC）值、最大标准摄取值（SUV）max与预后因素之间的关系进行了统计学评估。ILC肿块型的ADC值较低。在3级和4级背景实质强化及阳性淋巴结转移中，SUVmax在统计学上较高。DWI的ADC值和PET/CT的SUVmax有助于预测ILC的预后。
