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.
A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.
The concept of grading of the tumors of the central nervous system, agreeing for such the regulation of the "progressiveness" of these neoplasias (from benign and localized tumors to malignant and infiltrating tumors), dates back to 1926 and was introduced by P. Bailey and H. Cushing, [1] in the elaboration of what turned out the first systematic classification of gliomas.
The 5th WHO classification delineates distinct types of tumors, some of them being further divided into subtypes, rendering the former terms entity and variant obsolete. When molecular diagnostics are not complete enough to allow precise classification, diagnosis should be designated by appending not otherwise specified (NOS).
A vestibular schwannoma (VS) is only one type of tumor. The Central Brain Tumor Registry of the United States (CBTRUS) is the primary national database of malignant and benign tumors of the brain, "other central nervous system (CNS), tumors of the pituitary and pineal glands, olfactory tumors of the nasal cavity, and brain lymphoma and leukemia."
Removal of tumor tissues helps decrease the pressure of the tumor on nearby parts of the brain. [17] The main goal of surgery is to remove as much as possible of the tumor mass while preserving normal brain function, and to relieve the symptoms caused by the tumor such as headache, nausea and vomiting. [ 18 ]
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 ...
