TCIA CervicalCancer (CC Tumor Heterogeneity) Longitudinal multi parametric MRI + 18F FDG PET/CT collection of locally advanced cervical cancer patients undergoing chemoradiation, with radiation oncologist tumor contours (RTSTRUCT) defined on T2 weighted MRI as the gold standard. Each patient was imaged at three time points spanning the chemoradiation course. Dataset Details Field Value Modalities MR (T1W, T2W, DCE, DWI), 18F FDG PET, CT Body part Cervix / pelvis Task 3D tumor segmentation on T2W MRI (longitudinal) Patients 23 (CCTH A01 … CCTH A12, CCTH B01 … CCTH B11) Time points 3 per patient — Baseline (0 Gy) / Early (~20–25 Gy, 2–2.5 wk) / Mid treatment (~45–50 Gy, 4–5 wk) Studies 171 Series 821 Images 131,556 DICOM slices MR series 523 (15.91 GB) CT series 65 (11.48 GB) PET series 68 (0.99 GB) RTSTRUCT files 68 (≈ 23 patients × 3 time points; CCTH A06 has 2) REG (registration) files 97 Format DICOM (images) + DICOM RTSTRUCT (contours) + DICOM REG (registrations) License CC BY 4.0 Segmentation Tumor contours are stored as DICOM RTSTRUCT files in segmentations/ .
