Dural tail sign seen associated with a meningioma. The dural tail sign (also known as "dural thickening", "flare sign", or "meningeal sign") is a radiological finding observed in magnetic resonance imaging (MRI) studies of the brain that refers to a thickening of the dura mater immediately adjacent to a mass lesion, such as a brain tumor.

Automatic segmentation ITK-SNAP provides automatic functionality segmentation using the level-set method. This makes it possible to segment structures that appear somewhat homogeneous in medical images using very little human interaction. For example, the lateral ventricles in MRI can be segmented reliably, as can some types of tumors in CT and ...

Brain Tumor Segmentation under Studierfenster. Aortic Dissection Inpainting under Studierfenster. Studierfenster or StudierFenster (SF) [1] [2] [3] is a free, non-commercial open science client/server-based medical imaging processing online framework.
In the following, the image is segmented into non-brain and brain tissue, with the latter usually being sub-segmented into at least gray matter (GM), white matter (WM) and cerebrospinal fluid (CSF). Since image voxels near the class boundaries do not generally contain just one kind of tissue, partial volume effects ensue that can be corrected for.
Tumor volumes were defined either by expert radiation oncologists or using semiautomatic segmentation methods. [ 22 ] [ 23 ] Their results identified a subset of radiomic features that may be useful for predicting patient survival and describing intratumoural heterogeneity.
For instance, it has been utilized in academic research involving automatic cranio-facial implant design, [29] brain tumor analysis from Magnetic Resonance images, [30] identification of features in focal liver lesions from MRI scans, [31] radiotherapy planning for prostate cancer, [32] preparation of datasets for fluorescence microscopy ...
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
