Proton MR spectroscopy of pediatric cerebellar tumors.
PURPOSE To investigate the role of proton MR spectroscopy in pediatric cerebellar tumor diagnosis. METHODS Single voxel pulse sequences with long echo time (135 or 270 milliseconds, voxel size 8 to 19 cm3), were used to obtain proton spectra of primary pediatric cerebellar tumors. Eleven primitive neuroectodermal tumors (patient age, 2 to 12 years; mean, 7 years), 11 low-grade astrocytomas (a...
متن کاملProton Mr Spectroscopy in Brain Metabolic Disorders
Metabolic disorders of the central nervous system (CNS) include pathologies with extremely different pathogenesis. The clinical diagnosis of these disorders is often very difficult and requires sophisticated laboratory investigations. Proton magnetic resonance (MR) spectroscopy (1H-MRS) has been recently used in a number of clinical studies to supplement conventional MRI as it is able to provid...
متن کاملEvaluation of Diagnostic Value of CT Scan and MRI in Brain Tumors and Comparison with Biopsy
Abstract Background Cerebral neoplasm arises from brain, spinal cord and meningeal cells. Not only malignant cerebral neoplasm also benign tumor could lead to death due to mass effect on vital structures. Access to these tumors is difficult, and MRI and CT scan could be helpful in determining anatomical location of tumors and distinction of malignant from benign. Objective For better and ea...
متن کاملMultivoxel proton MR spectroscopy and hemodynamic MR imaging of childhood brain tumors: preliminary observations.
PURPOSE To assess multivoxel proton MR spectroscopy combined with MR imaging and hemodynamic MR imaging in the evaluation of brain tumors in children and young adults. METHODS Fifteen patients with brain tumors and 10 healthy children underwent MR imaging and MR spectroscopy on a 1.5-T system. Ten patients with tumors had both MR spectroscopy and hemodynamic MR imaging. MR spectroscopy data s...
