QIN-Breast

由纵向PET/CT效应和定向MR图像组成的QIN-乳腺数据集用于研究乳腺癌辅助治疗的新方法，其中包含68例患者的100,835张图像。数据集涵盖三个时间段的图像: 治疗开始前的T1; 治疗一个周期后的T2; 以及第二个治疗周期或所有治疗完成后的T3。
该数据集的价值在于临床影像学数据，可用于开发和评估定量影像学方法，以早期评估乳腺癌治疗。数据由范德比尔特大学的Thomas E. Yankeelov博士，PI提供，设备为GE Discovery STE扫描仪。扫描CT的采集数据如下: 对于称重70千克的患者，管电流为80mAs，管电压为120kVp，间距为1.675/1，FDG给药活性为约370MBq。每隔2分钟1小时后，以3D模式收集每张床的发射数据，最初仅用于乳房俯卧位，随后用于从颅骨到股骨中部的仰卧位数据。
该数据集由癌症影像档案TCIA 2016年发布，相关论文 “来自QIN-Breast.the Cancer Imaging Archive”。

The QIN-Breast Dataset, consisting of longitudinal PET/CT imaging and targeted MR images, is intended for investigating novel approaches to breast cancer adjuvant therapy. It contains 100,835 images from 68 patients.

The dataset includes images acquired at three time points: T1 prior to the start of treatment; T2 after one cycle of treatment; and T3 after the second treatment cycle or upon completion of all treatment.

The value of this dataset lies in its clinical imaging data, which can be used to develop and evaluate quantitative imaging methodologies for early assessment of breast cancer treatment response. This dataset was provided by Dr. Thomas E. Yankeelov, Principal Investigator (PI), from Vanderbilt University, using a GE Discovery STE scanner.

The acquisition parameters for the CT and PET scans are as follows: For patients weighing 70 kg, the tube current was set to 80 mAs, tube voltage to 120 kVp, and pitch to 1.675/1. The administered FDG activity was approximately 370 MBq. Starting 1 hour after injection, emission data for each couch position was collected in 3D mode every 2 minutes. Initially, scanning was only performed in the prone breast position, and later extended to supine scanning from the skull to the mid-femur.

This dataset was released by The Cancer Imaging Archive (TCIA) in 2016, with the associated research paper titled "QIN-Breast: The Cancer Imaging Archive".
