The proposed HCNN technique achieved99.35% sensitivity, 99.22% specificity, and 99.04% segmentation accuracy on brain Magnetic Resonance Imaging (MRI) in the Nanfang dataset. The proposed system obtains 99.81% classification accuracy, 99.2% sensitivity, 99.7% specificity and 99.8% segmentation accuracy ...
MRI spectroscopy can be used to detect malignant meningiomas by comparing the metabolic and chemical contents of the healthy tissue with malignant tumor. Brain MRI also helps identify cystic lesions in meningiomas; a mushroom-like appearance reflects tumor invagination in the brain parenchyma. [1] ...
(ICA) and the anterior cerebral artery (ACA) in both sides of the brain were both intact. (See Figure 2) After the operation, the patient’s vision also returned to normal, and she returned to mainland China three days later. MRI examinations four years later confirmed that the tumor ...
Signs and symptoms are based on which area of the brain is compressed by the tumor. In the elderly, midline tumors can cause dementia without any focal neurologic problems. Diagnosis The diagnosis of meningioma is by MRI, using a paramagnetic contrast agent. With CT scans or plain X-rays, ...
Brain MRI showed a mass in the base of right middle cranial fossa. The mass was completely removed. Histopathologic and radiographic findings provided evidence for a collision composed of meningioma and metastatic renal clear cell carcinoma.The Clinical NeuropsychologistQingquan BaoShanlu YuXuebin Yu...

Methods Thirty-eight cases of meningioma confirmed by surgery and pathology were reviewed, and their MRI features of the meningioma and histological type were analyzed, including the signal appearance of the tumor, tumor-brain interface status, peritumorous edema, tail sign, and the signal uniformity...
