Aortic Dissection Dataset and Segmentations

This dataset consists of a type B Aortic Dissection (AD) CTA collection with true and false lumen expert annotations. It can be used for the development of AI-based algorithms for an automatic segmentation of ADs.For a review about the detection, segmentation, simulation and visualization of Aortic Dissections, please see:Pepe A, Li J, Rolf-Pissarczyk M, Gsaxner C, Chen X, Holzapfel GA, Egger J.

data on white matter lesions in bipolar disorder

The data sheet contains all volumetric and demographic variables and that were used for statistical analysis in our study. Data are either continuous or binary. A comprehensive description of variables is given in the file

Demographic data.

<p>Note: Results from <i>t</i>-tests (<i>t</i>), Chi square tests (<i>χ2</i>), Mann-Whitney-U-tests (<i>U</i>) and ANCOVA (<i>F</i>)</p><p>(1) For ANCOVA, WML volumes were normalized by individual total intracranial volume and controlled for age, diabetes, smoking and BMI.</p><p>Statistically significant effects are marked bold.</p><p>Demographic data.</p

Representative FLAIR slice of one patient.

<p>The left image shows an example of lesion areas, outlined semiautomatically by the instructed rater using a custom written IDL program (Exelis Visual Information Solutions, USA). The right image shows the native FLAIR scan.</p
