AbstractGliomas are among the most aggressive and deadly brain tumors. This paper details proposed Deep Neural Network architecture for tumor segmentation from Magnetic Resonance Images. The consists of a cascade three Layer Aggregation neural networks, where each stage elaborates response using feature maps probabilities previous stage, MRI channels as inputs. neuroimaging data part publicly a...

background : central nervous system tumors account for 2%-5% of all malignancies in humans. these tumors account for 2% of all pediatric cancers. the worldwide incidence of primary central nervous system tumors is estimated at 3.9 (males) and 3.2 (females) per 100000 person-years. the incidence of brain tumor cases has been reported as 3.67% of all malignancies and 4% of all cancer mortalities ...

abstract background: asterocytoma is the most common primary human brain tumor which has the most lethal hazard among tumors in human central nervous system. heat shock proteins play an active role in cancer cells pathways through their effects on tumor cell proliferation, tumor differentiation, malignancy, metastasis, and cell death. hsp 70 is a 70 kd protein that its expression change has bee...

Blood–Brain Barrier Therapy The blood–brain barrier (BBB) is a bottleneck in the treatment of brain tumors. In article number 2203678, Liang Wang, Yinyan Lin Feng, and co-workers summarize current approaches to overcome BBB, such as use “Trojan horse” molecular modifications for deception, describe variety micro-nanocarriers targeted tumor therapy.

neurofibromatosis type 2 is an inherited disease. the main manifestation of the disease is the development of symmetric, non-malignant brain tumors in the region of the cranial nerve viii usually as schwannoma. we report here a 20-year-old woman with primary intracranial malignant nerve sheath tumor located in the left cerebellopontine angle. histologically, the tumor showed malignant spindle c...

background: medulloblastoma is the most common malignant brain tumor in children. the important factors in predicting survival are the extent of disease, proliferation index of the tumor cells, histopathologic class and the age at diagnosis. the percentage of ki-67 positive cells reflects the proliferation  of the cells and is one of the critical factors which determine the growth of the tumor....

in this study, 22 patients (15-75 years old) were selected and transferred to ct scan for tumor ablation. for ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. then, laser probe inserted through the needle and laser energy delivered. although we ...

In this paper, we propose a Hybrid High-resolution and Non-local Feature Network (H $$^2$$ NF-Net) to segment brain tumor in multimodal MR images. Our H NF-Net uses the single cascaded HNF-Nets different sub-regions combines predictions together as final segmentation. We trained evaluated our model on Multimodal Brain Tumor Segmentation Challenge (BraTS) 2020 dataset. The results test set show ...
