Magnetic Resonance Spectroscopy in the Brain
ثبت نشده
چکیده
Standard clinical MR images depend on magnetic resonance signals of hydrogen nuclei, which are present in very high concentrations in water and, to a lesser extent in lipids. Although other hydrogen-containing metabolites are present, their concentrations are too low to contribute significantly to the MR signal unless the water signal is suppressed. This can be achieved using a chemical-selective saturation radiofrequency pulse.

Detection of Glioblastoma Multiforme Tumor in Magnetic Resonance Spectroscopy Based on Support Vector Machine
Introduction: The brain tumor is an abnormal growth of tissue in the brain, which is one of the most important challenges in neurology. Brain tumors have different types. Some brain tumors are benign and some brain tumors are cancerous and malignant. Glioblastoma Multiforme (GBM) is the most common and deadliest malignant brain tumor in adults. The average survival rate for peo...
متن کاملApplication of Magnetic Resonance Spectroscopy in Neurocognitive Assessment After Head Injury: A Systematic Review
Background: Traumatic brain injury is believed to be a public health disorder with some complications. Post Traumatic Neurocognitive Disorders (PTND) received much attention among these complications because of the high prevalence of mild traumatic brain injuries. On the other hand, advanced neuroimaging is increasingly becoming an exciting modality in the field of traumatic brain injury. Magne...
متن کاملApplication of magnetic resonance spectroscopy for evaluating metabolic alteration in anterior cingulate cortex in Alzheimer's disease
Introduction: Alzheimer’s disease (AD) is the most common cause of dementia worldwide. Mild cognitive impairment (MCI) is often the prodromal stage to AD. Most patients with MCI harbor the pathologic changes of AD and demonstrate transition to AD at a rate of 10–15% per year. Accumulating evidence indicates that the asymmetry changes of left and right brain have happened in the early stage of A...
