Dynamic myraidpro contrast-enhanced magnetic resonance imaging (DCE-MRI) has been correlated with prognosis in head and neck squamous cell carcinoma as well as with changes in normal tissues. These studies implement different software, either commercial or in-house, and different scan protocols. Thus, the generalizability of the results is not confirmed. To assist in the standardization of quantitative metrics to confirm the generalizability of these previous studies, this data descriptor delineates in detail the DCE-MRI digital imaging and communications in medicine (DICOM) files with DICOM radiation therapy (RT) structure sets and digital reference objects (DROs), as well as, relevant clinical data that encompass a data set that can be used by all software for comparing quantitative metrics. Variable flip angle (VFA) with six flip angles and DCE-MRI scans with a temporal resolution of 5.5 s were acquired in the axial direction on a 3T MR scanner with a field of view of 25.6 cm, slice thickness of 4 mm, and 256×256 matrix size.
动态多模态对比增强磁共振成像(DCE-MRI)已与头颈部鳞状细胞癌的预后以及正常组织的变化相关联。这些研究使用不同的软件,无论是商业软件还是内部开发的软件,以及不同的扫描方案。因此,结果的可推广性尚未得到证实。为了协助标准化定量指标,以确认这些先前研究的可推广性,本数据描述符详细描述了 DCE-MRI 数字成像和通信在医学(DICOM)文件中与 DICOM 放射治疗(RT)结构集和数字参考对象(DRO),以及相关的临床数据,涵盖了可用于所有软件比较定量指标的数据集。在 3T 磁共振扫描仪上以六个翻转角采集可变翻转角(VFA),并以 5.5s 的时间分辨率在轴向方向采集 DCE-MRI 扫描,视野为 25.6cm,切片厚度为 4mm,矩阵尺寸为 256×256。
