Brain (MRI)

Learning objectives

Upon completing this study unit you will be able to:

Understand the need for different types MRI sequences of the brain.
Identify T2-weighted MRI images.
Learn about the main structures of the brain identified in such images and their anatomical relations.

Explore MRI scan

MRI equipment can obtain different types of images from a single patient, allowing for many types of different contrast between adjacent structures. These types of images are named sequences.

One of the most important sequences for brain imaging is one called T2-weighted sequence. On T2-weighted images cerebrospinal fluid (CSF) - or any type of clear fluid - shows a marked hyperintensity (white color), while still allows for a fair differentiation between the gray and white matter of the brain.

The following images will show you some of the anatomical structures that are identifiable with T2-weighted MRI of the brain.
