SPIE-AAPM-NCI PROSTATEx Challenges

“SPIE-AAPM-NCI PROSTATEx挑战数据集是来自研究挑战的前列腺图像数据集。

该研究是一组回顾性的前列腺MRI研究，包括分别来自西门子3t MR扫描仪，MAGNETOM Trio和Skyra的T2-weighted，质子密度加权，动态对比增强和扩散加权成像，其中，T2-weighted使用具有约0.5毫米的平面内分辨率和3.6毫米的切片厚度的turbo自旋回波序列，随后是具有约1.5毫米的平面内分辨率和4毫米的切片厚度的3D turboflash梯度回波序列获得。切片厚度和3.5s时间分辨率最后，使用单词回波平面成像序列获取DWI系列，该序列的平面内分辨率约为2毫米，切片厚度为3.6毫米，在三个方向上具有扩散编码梯度。

该数据集的相关挑战是前列腺挑战 (SPIE-AAPM-NCI前列腺MR分类挑战) 和PROSTATEx-2挑战 (SPIE-AAPM-NCI前列腺MR格里森级组挑战)。

Spie-aapm-nci PROSTATEx挑战数据集包含346名患者的总共309,251张图像，由癌症成像档案TCIA 2016年发布，相关论文包括 “ProstateX挑战数据”。

SPIE-AAPM-NCI PROSTATEx Challenge Dataset is a prostate imaging dataset sourced from a research challenge.

This study comprises a set of retrospective prostate MRI studies, including T2-weighted, proton density-weighted, dynamic contrast-enhanced, and diffusion-weighted imaging sequences acquired via Siemens 3T MR scanners, specifically the MAGNETOM Trio and Skyra models. T2-weighted imaging was acquired using a turbo spin-echo sequence with an in-plane resolution of approximately 0.5 mm and a slice thickness of 3.6 mm, followed by a 3D turboflash gradient-echo sequence with an in-plane resolution of approximately 1.5 mm and a slice thickness of 4 mm. The final DWI series was obtained using a single-shot echo planar imaging sequence, which featured an in-plane resolution of approximately 2 mm, a slice thickness of 3.6 mm, diffusion encoding gradients in three directions, and a temporal resolution of 3.5 s.

The relevant challenges linked to this dataset are the Prostate Challenge (SPIE-AAPM-NCI Prostate MR Classification Challenge) and the PROSTATEx-2 Challenge (SPIE-AAPM-NCI Prostate MR Gleason Grade Group Challenge).

The SPIE-AAPM-NCI PROSTATEx Challenge Dataset contains a total of 309,251 images from 346 patients, and was released by the Cancer Imaging Archive (TCIA) in 2016, with the associated paper titled "ProstateX Challenge Data".
