QIN-BREAST-02

<p>This data is from a multi-site, multi-parametric quantitative MRI study of adult (18+ years old) females diagnosed with invasive breast cancer.  Subjects all had a lesion size >1cm in longest dimension and were undergoing neoadjuvant therapy. Participants were scanned prior to any therapy and then 2-3 times after the initiation of neoadjuvant therapy, depending upon their treatment regimen. All data sets were acquired with a research-only protocol, including: DWI (SE EPI), OGSE, qMT, B0 map, multi-flip T1 map, Bloch-Siegert B1 map, DCE, and a T1-weighted anatomical image.</p><p>This dataset is an extension of the original <a href="https://cancerimagingarchive.net/collection/qin-breast/" target="_blank" rel="noopener">QIN-BREAST</a> collection, with updated scan protocols and data collected at both Vanderbilt University Medical Center and the University of Chicago to demonstrate reproducible results at multiple sites (both using Philips 3T MR scanners).</p>

本数据集源自一项多中心、多参数定量MRI研究，研究对象为经诊断患有侵袭性乳腺癌的成年女性（年龄≥18岁）。所有受试者最长径的肿瘤直径均大于1厘米，且正在接受新辅助治疗。受试者在任何治疗前及新辅助治疗启动后2-3次，根据其治疗方案进行扫描。所有数据集均采用仅用于研究的扫描方案获取，包括：弥散加权成像（SE EPI）、表观弥散张量成像（OGSE）、定量磁共振成像（qMT）、B0图、多翻转T1图、Bloch-Siegert B1图、动态对比增强成像（DCE）以及T1加权解剖图像。本数据集是对原始的QIN-BREAST（<a href="https://cancerimagingarchive.net/collection/qin-breast/" target="_blank" rel="noopener">QIN-BREAST</a>）数据集的扩展，包含了更新后的扫描方案，以及在美国范德堡大学医学院和芝加哥大学收集的数据，旨在展示多中心（均使用Philips 3T磁共振扫描仪）的可重复性结果。
