The images archived here are the same-session\nrepeatability (\"coffee break\") exams for 5 primary breast cancer patients: each patient was scanned\ntwice, 15 minutes apart, establishing the per-patient distribution of ADC change in the absence of\nany biological change — the null against which treatment-related change is judged. Both exams of a\npair provide diffusion-weighted images at b = 0 and b = 800 s/mm² and a derived ADC map, and the\nfirst exam adds an anatomical reference series and a tumor reference volume-of-interest (VOI) mask.\nPlease see the RIDER Breast MRI (https://doi.org/10.7937/K9/TCIA.2015.H1SXNUXL) page to learn more\nabout the images and to obtain any supporting metadata for this collection.","patients":5,"studies":10,"series":40,"instances":2400,"size_TB":0.0,"modalities":["MR"],"licenses":[{"license_short_name":"CC BY 3.0","series":40,"size_TB":0.0}]}
