Abstract

A brief review of neuroimaging using functional magnetic resonance imaging (fMRI)

Highlights

Since the turn of 21st century, improvements in medical imaging have been considered one the greatest triumphs in the history of modern medicine
Blood-oxygen-level-dependent (BOLD) magnetic resonance imaging (MRI), known as functional MRI, overcomes these limitations and enables physicians to visualize the activity of the brain.[1]
Clinicians should consider the effect of sedation, medications and anxiety on the hemodynamic response and subsequent signal. functional MRI (fMRI) can be dangerous for people with pacemakers and metal valves

Summary

Introduction

Since the turn of 21st century, improvements in medical imaging have been considered one the greatest triumphs in the history of modern medicine. Blood-oxygen-level-dependent (BOLD) MRI, known as functional MRI (fMRI), overcomes these limitations and enables physicians to visualize the activity of the brain.[1] Changes in blood flow act as a marker for metabolic activity and neuronal firing, as blood flow increases to more active regions.
