ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. a seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. imaging findings were suggestive of left temporal high grade lesion. during surgery there was well ca...

The main idea of this work is to reduce the physician time by assessing with computer aided tumor detection Human investigation routine technique for brain MRI and tumors classification. Interpretation images based on organized explicit classification also various techniques have been proposed. proposed system segments Brain MR help fuzzy corner points segmented area subjected grade Support vec...

Background: Glioma is the most common primary brain tumor, and early detection of tumors is important in the treatment planning for the patient. The precise segmentation of the tumor and intratumoral areas on the MRI by a radiologist is the first step in the diagnosis, which, in addition to the consuming time, can also receive different diagnoses from different physicians. The aim of this study...

The ability to accurately distinguish remaining or recurrent high-grade astrocytoma from necrosis or edema following treatment is essential to optimal patient management. Thallium 201 planar -y-caméra imaging has been shown to be helpful in detecting recurrent high-grade astrocytoma; however, due to tissue heterogeneity adjacent to and within tumor, the cellular specificity and quantification ...

High-grade endometrial stromal sarcoma is a rare uterine malignancy. The cells of these tumors resemble endometrial cells in the proliferation stage, with many small plexiform arterioles. Herein we present a patient with endometrial stromal sarcoma that metastasized to the brain, along with the CT and MRI findings and a discussion of the surgical and histopathological features of the metastatic...

E1 region replacement adenoviruses are replication defective and are propagated in cells providing adenovirus E1A and E1B proteins. Although they are being developed for antitumor therapies, the proliferative behaviors of these viruses in normal brain tissues or in brain tumors are unknown. To address this, freshly cultured cells from normal human brain and common brain tumors (astrocytomas and...

This work presents a method for classification and segmentation of brain tumors based on deep learning analysis contrast T1 (T1c) MR images. To achieve this goal, three different networks are investigated i.e., U-Net, VGG16-Segnet, DeepLabv3+ models. In addition, the integration 3D narrow-band information MRI volumes is imported to input Convolutional Neural Network (CNN) describe more accurate...

This study aimed to determine the potential value of intravoxel water diffusion heterogeneity imaging for brain tumor characterization and evaluation of high-grade gliomas, by comparing an established heterogeneity index (alpha value) measured in human high-grade gliomas to those of normal appearing white and grey matter landmarks. Twenty patients with high-grade gliomas prospectively underwent...

Over the last two decades the large volume of research involving various brain tracers has shed invaluable light on the pathophysiology of cerebral neoplasms. Yet the question remains as to how best to incorporate this newly acquired insight into the clinical context. Thallium is the most studied radiotracer with the longest track record. Many, but not all studies, show a relationship between (...

One of the most important tasks used by medical profession for disease identification and recovery preparation is automatic image processing. Statistical approaches are commonly algorithms, they consist several step. Brain tumors foremost causes death cancerous diseases all over world. The hippocampus human body’s primary control structure. Since a tumor attacks brain, it can kill patient if no...
