Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 1, Page 36-43, July 2024.ABSTRACT Objective Although remarkable strides have been made in fetal medicine and the prenatal diagnosis of congenital heart disease, around 60% of newborns with isolated coarctation of the aorta (CoA) are not identified prior to birth. The prenatal detection of CoA has been shown to have a notable impact on survival rates of affected infants.

基于多参数MRI的影像组学特征对泪腺良恶性上皮性肿瘤的诊断价值研究
Zhongguo shiyan zhenduanxue, 2023 原发于泪腺区的肿瘤发病率较低，约占所有眼眶肿瘤的6%～12%[1-2]，其中以泪腺上皮性肿瘤最为常见，约占所有泪腺肿瘤的50%左右[3]。泪腺上皮性肿瘤成分复杂，组织结构易变异，术后易复发，影像学表现复杂多变。目前对于泪腺上皮性肿瘤的良恶性鉴别多采用常规CT及MRI的定性研究[4]，也有DCE-MRI、DWI及ADC值核磁功能成像技术应用于眼眶病变的研究，王永哲等[5]应用表观扩散系数鉴别泪腺77例良恶性肿瘤，杨本涛等[6]应用扩散加权成像及ADC值研究泪腺上皮性肿瘤，在上皮及非上皮性肿瘤良恶性诊断方面，
