kneeMRI datasetDESCRIPTION:KneeMRI dataset was gathered retrospectively from exam records made on a Siemens Avanto 1.5T MR scanner, and obtained by proton density weighted fat suppression technique at the Clinical Hospital Centre Rijeka, Croatia, from 2006 until 2014. The dataset consists of 917 12-bit grayscale volumes of either left or right knees. Each volume record was assigned a diagnosis concerning the condition of the anterior cruciate ligament in a double-blind fashion, i.e. each volume record was labelled according to the ligament condition: (1) healthy, (2) partially injured, or (3) completely ruptured. A wider rectangular region of interest (ROI) was manually extracted from the original volumes, and is also annotated. For more details regarding the dataset, the reader is referred to the paper stated under the "acknowledging source" section of this webpage. This dataset was built with the intention of providing scientists, involved with machine vision and/or machine learning, an easy way of working with the data.
