A brain tumor is an excessive development of abnormal and uncontrolled cells in the brain. This growth considered deadly since it may cause death. The controls numerous functions, such as memory, vision, emotions. Due to location, size, shape these tumors, their detection a challenging complex task. Several efforts have been conducted toward improved yielded promising results outcomes. However,...

Giant cell glioblastoma is an extremely rare variant of Glioblastoma (WHO grade IV) which is characterized by a predominance of bizarre, multinucleated giant cells. These tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. In pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. Here, we report a case of a 12-year old female pat...

The brain is one of the important organs in human body. It controls functions such as vision, hail, memory, knowledge, personality, and difficulty at work. Numerous health associations have rated tumors an alternative major imbalance that causes highest number deaths worldwide. Diagnosis undiagnosed tumor provides opportunity for effective medical treatment. At diagnosis, a shows growth extra c...

Early identification and diagnosis of brain tumors have been a difficult problem. Many approaches proposed using machine learning techniques recent study has explored deep which are the subset learning. In this analysis, Feature extraction such as GLCM, Haralick, GLDM, LBP applied to Brain tumor dataset extract different features from MRI images. The extracted trained classification algorithms ...

Photoacoustic (PA) imaging has emerged as a promising technique for real-time detection and diagnosis of brain-related pathologies, due to its advantages in deep penetration ultrasound high resolution optical fluorescence imaging. We herein provide an overview on the latest developments nanoparticles contrast agents specifically designed PA brain tumor, vascular other diseases. Five design cons...

Using image segmentation techniques to assist physicians in brain tumor diagnosis is a hot issue computer technology research. Although most networks date have been based on U-Net, the prediction results are depending which not well generalized and need be further improved. As depth of network increases, gradients vanish together with decrease accuracy; meanwhile, large number parameters will c...

desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. it has been associated with scar from previous breast surgery or trauma. especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. we presented multimodality imaging findings (ultrasound, computed tomography, magnetic ...

tuberculoma is one of the causes of the space occupying lesions in brain. its manifestations can mimic many diseases such as tumor, vasculitis, and multiple sclerosis.a patient with brain tuberculoma secondary to epidymitis is reported. his symptoms and signs were verysimilar to the patients with multiple sclerosis. the physicians must keep in mind this disease in the differentialdiagnosis with...
