PurposeTo develop and evaluate a technique for accelerating phase contrast MRI (PC-MRI) acquisitions without significant compromise in flow quantification accuracy.MethodsPC-MRI is commonly acquired using interleaved flow-compensated (FC) and flow-encoded (FE) echoes. We hypothesized that FC data, ...
Purpose: To evaluate the feasibility and accuracy of generating simulated contrast-enhanced T1-weighted breast MRI scans from precontrast MRI sequences in biopsy-proven invasive breast cancer with use of deep learning.评估使用深度学习从未经对比增强的MRI序列生成模拟对比增强T1加权乳腺MRI扫描在经活检证实...
Method方法The purpose of this study was to develop and evaluate a DL system for predicting the probability of breast cancer in DCE-MRI. To do so, we collected a dataset of 21,537 DCE-MRI examinations from the NYU Langone Health sites. We used it to train, validate, and test t Fig. 1...

A person who has an MRI with contrast has a radioactive dye injected into them before the MRI is taken. This dye usually contains gadolinium. These... Learn more about this topic: Vocabulary of CT, MRI & PET Imaging from Chapter 30/ Lesson 16 ...
近年来随着MRI技术如扩散加权成像(diffusion weighted imaging,DWI)、动态对比增强MRI (dynamic contrast-enhanced magnetic resonance imaging,DCE-MRI)、化学位移成像的发展与应用,尤其是影像组学新技术的发展,诸多影像学特征很大程度上提高了良恶性VCFs鉴别诊断的准确性。该文就MRI技术和影像组学在良恶性VCFs鉴别诊断的...
Intravenous contrast is an important diagnostic tool in MRI for musculoskeletal infection. An association has been noted between gadolinium-based contrast agents and the development of nephrogenic systemic fibrosis in patients with end-stage chronic kidney disease, particularly in patients on dialysis. Give...
Each brain examination included a single axial series (either T2-weighted FLAIR, T1-weighted without contrast, or T1-weighted with contrast) where bounding box labels were placed on each image in which repre- sentative pathology or normal anatomical variant was identified17,18. As in knee ...
Improving breast cancer diagnostics with deep learning for MRI使用深度学习改善乳腺癌诊断的MRI技术 01文献速递介绍 乳腺磁共振成像(MRI)是一种高度敏感的检测乳腺癌的方式,报道的敏感性超过80%。传统上,其在筛查中的使用被限制在高风险患者身上。新的证据支持在中等风险和普通风险女性中进行筛查MRI的作用4)。诊断...
第五节 磁共振对比剂 MRI对比剂(MRI Contrast Agrnt)指通过静脉注射将对比剂注入机体,以增加组织对比。磁共振对比剂本身不产生信号,它是通过影响质子的弛豫时间,间接改变信号强度,属于间接对比剂。 分类 … 悟而知行 核磁共振成像(MRI) 弗兰克奇发表于无损检测学...打开...
