Anonymized Image Data for DWI and T2W MRI Registration Quality Assurance

The following are pre-radiotherapy T2W and DWI MRI sequences in Digital Imaging and Communications in Medicine (DICOM) format for 20 patients curated from the MD Anderson Databases (NCT03145077). <br> For each image set (T2W image and DWI image), ground truth segmentations for the left and right submandibular glands, left and right parotid glands, cervical spinal cord, brainstem, and primary gross tumor volume were manually generated by a trained physician expert (radiologist with &gt; 5 years of experience in HNC). In a subset of five cases, segmentations for all structures in both sequences were also manually generated by three additional separate observers (two physicians and one medical student). All segmentations were generated in Velocity AI (v.3.0.1; Varian Medical Systems; Palo Alto, CA, USA) in DICOM RT structure format. <br> DICOM data was anonymized using an in-house Python script that implements the RSNA CRP DICOM Anonymizer software. All files have had any DICOM header info and metadata containing PHI removed or replaced with dummy entries.
