Dataset: Anatomical Tracings of Lesions after Stroke (ATLAS)
|Dataset Full Name||Anatomical Tracings of Lesions after Stroke|
Release 1.2* of the Anatomical Tracings of Lesions After Stroke (ATLAS) Dataset is a collection of 304 T1-weighted MRIs (Magnetic Resonance Images) with manually segmented diverse lesions and metadata. ATLAS is designed to provide researchers with a standardized training and a testing dataset for lesion segmentation algorithms on T1-weighted MRIs. It can also be used to compare different lesion segmentation techniques.
The images were collected across 11 research groups worldwide participating in the ENIGMA Stroke Recovery Working Group consortium. Brain lesions were identified and masks manually drawn on each individual brain MRI using MRIcron, an open-source tool for brain imaging visualization. Quality control was performed on each lesion mask by a second tracer, including categorizing lesions. Additional metadata includes qualitative descriptions of the type of stroke, vascular territory, and intensity of white matter disease developed by an expert neuroradiologist.
*Version 1.1 was updated to v.1.2 on 11/27/2018 with corrections to images in Cohorts 1 and 2 in the previous dataset. The study also included a new version of the metadata data file. The ICPSR codebook has also been updated based on that file.

|Data Collection Frequency||Varies with individual patient. Some have multiple MRIs and metadata over time.||Strengths and Limitations|
|Strengths||Large sample of MRI images. In cases with multiple lesions each non-contiguous lesion is identified and masked. Extensive meta-data developed by expert neuroradiologists are available regarding lesion properties and location(s). In some cases longitudinal data is available. Multiple tracers used to ensure data and tracing quality. All image data can be easily accessed using free open source software. Standardized MRI images are available for over three quarters of the cases (n=239).|
|Limitations||No information regarding the lesion(s) impact on individual functioning.||Data Details|
