Summary<\/h2>

This collection contains a labeled dataset of MRI images collected on 242<\/span>\u00a0<\/span>consecutive patients with vestibular schwannoma (VS) undergoing Gamma Knife stereotactic radiosurgery (GK SRS). The structural images included contrast-enhanced T1-weighted (ceT1) images and high-resolution T2-weighted (hrT2) images. Each imaging dataset is accompanied by the patient\u2019s radiation therapy (RT) dataset including the RTDose, RTStructures and RTPlan. Additionally, registration matrices (.tfm format) and segmentation contour lines (JSON format) are provided and described\u00a0<\/span><\/span>below.\u00a0<\/span>All structures were manually segmented in consensus by the treating neurosurgeon and physicist using both the ceT1 and hrT2 images. The value of this collection is to provide clinical image data including fully annotated tumour segmentations to facilitate the development and validation of automated segmentation frameworks. It may also be used for research relating to radiation treatment.<\/span><\/p>

Imaging data from consecutive patients with a single sporadic VS treated with GK SRS between the years of\u00a02012<\/span> and 2018<\/span><\/span>\u00a0<\/span>were screened for the study. All adult patients older than 18 years with a single unilateral VS treated with GK SRS were eligible for inclusion in the study, including patients who had previously undergone operative surgical treatment. In total, 248 patients met these initial inclusion criteria including 51 patients who had previously undergone surgery. Patients were only included in the study if their pre-treatment image acquisition dataset was complete;\u00a04 patients were thus excluded because of incomplete datasets and 2 further patients were excluded because the tumour was not completely contained in the image field of view.\u00a0<\/span>The images were obtained on a 32-channel Siemens Avanto 1.5T scanner using a Siemens single-channel head coil.<\/span><\/p>
