Background: Glioma is the most common primary brain tumor, and early detection of tumors is important in the treatment planning for the patient. The precise segmentation of the tumor and intratumoral areas on the MRI by a radiologist is the first step in the diagnosis, which, in addition to the consuming time, can also receive different diagnoses from different physicians. The aim of this study...

While magnetic resonance imaging (MRI) is the gold-standard imaging modality for diagnosis of intracranial neoplasia, computed tomography (CT) remains commonly used for diagnosis and therapeutic planning in veterinary medicine. Despite the routine use of both imaging modalities, comparison of CT and MRI has not been described in the canine patient. A retrospective study was performed to evaluat...

OBJECTIVE Magnetic resonance imaging (MRI) grading systems using sagittal images are useful for evaluation of lumbar foraminal stenosis. We evaluated whether such a grading system is useful as a diagnostic tool for surgery. METHODS Between July 2014 and June 2015, 99 consecutive patients underwent unilateral lumbar foraminotomy for lumbar foraminal stenosis. Surgically confirmed foraminal ste...

Abstract BACKGROUND Glioma are currently classified according to integrated histopathologic and molecular genetic (WHO 2021 classification) as well methylomic criteria (Capper 2018). However, little is known about proteomic profiling of these subgroups , which may reveal specific biomarkers pathways potentially activated or inactivated. Material METHODS Eighty-six glioma biopsy samples were pro...

INTRODUCTION Current MRI sequences are limited in identifying brain areas at risk for high grade glioma recurrence. We employed intraoperative 3-Tesla functional MRI to assess cerebrovascular reactivity (CVR) after high-grade glioma resection and analyzed regional CVR responses in areas of tumor recurrence on clinical follow-up imaging. METHODS Five subjects with high-grade glioma that underw...

BACKGROUND To study the survival outcome and neurotoxicity grades in patients of high-grade glioma (HGG) treated with conformal radiation and temozolamide. MATERIALS AND METHODS Forty-six patients of HGG received conformal post operative radiation and temozolamide in the period 2003 to 2007. Twenty seven patients had near total resection, 17 had subtotal resection and 2 had biopsy only. 33 pa...

AIM To observe the outcomes of 1H- MR-spectroscopy (MRS) guided gamma knife surgery for treatment of glioma. MATERIAL AND METHODS Twenty patients with glioma diagnosed pathologically were randomly divided into MRI group and MRI plus MRS group. The target volume was defined as the tumor enhanced area plus the surrounding area with a short T1 and a long T2 in the MRI group, while the tumor enha...

BACKGROUND In patients with osteoarthritis, a detailed assessment of degenerative cartilage disease is important to recommend adequate treatment. Using a representative sample of patients, this study investigated whether MRI is reliable for a detailed cartilage assessment in patients with osteoarthritis of the knee. METHODS In a cross sectional-study as a part of a retrospective case-control ...

Gliomas are brain tumours classified into four grades with increasing malignancy from I to IV. The development and the progression of malignant glioma largely depend on the tumour vascularization. Due to their tissue heterogeneity, glioma cases can be difficult to classify into a specific grade using the gold standard of histological observation, hence the need to base classification on a quant...
