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 ...
(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 ...
MRI图像 【影像表现】 Axial non contrast enhanced CT [Figure 1] shows a large lesion isointense to the brain in the frontal lobes crossing the midline. Contrast enhanced axial image Figure 2] shows avid contrast enhancement of the lesion. T2W axial image (Figure 3) shows a mixed signal large...
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, ...
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...
(3) Because my symptoms were not debilitating and the majority of the meningioma brain tumor was still growing, I was given the option to “watch and wait” with a follow-up MRI in January 2019 to determine the rate of growth. My neurosurgeon said if the tumor had not grown, I could ...

Second, 68 Ga-DOTA(TOC/NOC/TATE) PET-CT provides high-contrast images of meningiomas due to the abundance of somatostatin receptor 2 in meningiomas but not in brain (except the pituitary gland) and bone. PET-CT has shown to be more sensitive than MRI to detect meningiomas [194, 195] and...
Objective To investigate the atypical manifestation of the meningioma in the low field MRI, in order to improve the accuracy of diagnosis. Methods: retrospective analysis of the operation pathology and clinical follow-up confirmed the MRI findings of 14 meningioma, which with the atypical MRI feature...
