Neural Stem Cells in Brain Tumor Development
… astrocytomas are highly invasive and incurable brain tumors. Mouse models that genetically resemble the human disease are valuable tools in understanding the pathogenesis of these malignancies. We previously reported mouse models based on conditional inactivation of the human …

Using Poisson's Equation to Characterize Brain Tumor Shape
The role that tumor shape plays in disease treatment, progression, and outcome is not well understood. This work investigates the quantification of shape information required for the statistical analysis of tumors. The statistical shape characterization method proposed by Haidar et al. 2006 that …

Diffusion Tensor Imaging in Pediatric Brain Tumor Patients
… Diffusion Tensor Imaging (DTI) to the pediatric brain tumor population. We discuss the theory and application of DTI as it was performed in a series of translational investigations at St. Jude Children’s Research Hospital. We present evidence of how the introduction of this technique impacted …

Brain Tumor Detection and Classification from MRI Images
<p>A brain tumor is detected and classified by biopsy that is conducted after the brain surgery. Advancement in technology and machine learning techniques could help radiologists in the diagnosis of tumors without any invasive measures. We utilized a deep learning-based approach to detect and …

Recognizing deviations from normalcy for brain tumor segmentation
A framework is proposed for the segmentation of brain tumors from MRI. Instead of training on pathology, the proposed method trains exclusively on healthy tissue. The algorithm attempts to recognize deviations from normalcy in order to compute a fitness map over the image associated with the …

Deconvolute Brain Tumor Genomic Alterations Based On Dna Methylation
… and treatment decision-making for patients with brain tumors, particularly malignant gliomas. However, the association between epigenetic signature and genetic alterations is poorly understood. For example, mutation of isocitrate dehydrogenase (<em>IDH</em>) is associated with genome-wide …

Brain Tumor Classification Using Hit-or-Miss Capsule Layers
<p>The job of classifying or annotating brain tumors from MRI images can be time-consuming and difficult, even for radiologists. To increase the survival chances of a patient, medical practitioners desire a means for quick and accurate diagnosis. While datasets like CIFAR, ImageNet, and SVHN have …

Analysis of The Operation Result Against Metastatic Brain Tumor
… 3(7.14%)례였는데 순수하게 수술과 연관도 합병증은 2례였다. 추후 대뇌 지도화(brain mapping)에 대한 연구가 좀더 활발해지면 전이성 뇌종양에 대한 수술적 치료의 영역이 더욱 확대될 것으로 사료된다. "

Survival Prediction For Brain Tumor Patients Using Gene Expression Data
Brain tumor is one of the most aggressive types of cancer in humans, with an estimated median survival time of 12 months and only 4% of the patients surviving more than 5 years after disease diagnosis. Until recently, brain tumor prognosis has been based only on clinical information such as tumor …

Multi-class segmentation of brain tumor using Convolution Neural Network
… architecture is used to segment multi-modal Brain Tumors from Magnetic Resonance (MR) images. Due to the challenges in manual segmentation, computerized brain tumor segmentation is one of the most important challenges in medical imaging. The fully convolutional structure of the network makes …

Local drug delivery for treatment of brain tumor associated edema
Brain tumor associated edema, a common feature of malignant brain neoplasms, is a significant cause of morbidity from brain tumor. Systemic administration of corticosteroids, the standard of care, is highly effective but can introduce serious systemic complications. Agents that inhibit the vascular …

Late Effects of Hypothalamic Radiation Exposure in Pediatric Brain Tumor Survivors
BACKGROUND: Brain tumors are the second most common childhood malignancy and overall survival rates exceed 70%. Pediatric brain tumor survivors treated with hypothalamic radiation are at increased risk for developing components of metabolic syndrome, characterized by central obesity and two of the …

DEVELOPING SURFACE-MODIFIED LANTHANIDE-DOPED NANOPARTICLES AS A BRAIN TUMOR THERANOSTICS
… because of the ability to traverse the blood-brain-barrier successfully. However, there are still several major challenges. Lanthanide-doped nanoparticles (Ln-doped NPs) have garnered immense potential for many biological studies but not much was utilized in GBM. This thesis will outline the …

Development and Evaluation of Brain Tumor Targeted Liposome Delivery System for Paclitaxel
<p>Primary brain tumors are a relatively common cause of cancer-related deaths. High-grade gliomas are the most common type of primary brain cancer, and the affected patients have a median survival of less than 1 year. Almost all malignant gliomas are incurable with the present standards of …
