Regardless of the platform (PC or Mac), the top left of the window shows a coronal view of the brain. The top right of the window shows a sagittal view of the brain. The bottom left of the window shows an axial (horizontal) view of the brain. Click the mouse at any brain location to move the blue viewing crosshairs. | |||

MRI is clinically very useful because it is non-invasive and safe. Because no exposure to radiation is involved, patients can receive many different kinds of MRI imaging procedures without risk. The MRI scanner can be programmed to create different kinds of images that reveal different tissue properties. The three main kinds of images are T1, T2 and Proton Density (FLAIR). The names of the image types refer to the physical priniciples used to create the images. The three links below link to three datasets, all collected from the same normal subject, that show the three different image types. Click on each link and save the file to your computer. | MRI is clinically very useful because it is non-invasive and safe.

This is the web page for information about downloadable MRI neuroanatomy teaching materials. The instructions below describe how to download MRI datasets and a freely available viewing program to look at them. REQUIRED Step 1: Download MRIcroN (free software for viewing MRI datasets)Download the correct installer package for your computer. Windows, Mac and Linux are supported; detailed installation instructions are provided for Windows and Mac but not Linux. For Windows: The following instructions were tested with Windows 7 running Internet Explorer 9. For different version of Windows or other web browsers, the steps may be slightly different.
After successfully starting the program, you should see the following window. To make the images easier to see, you can enlarge the window. Go to Step 2, below. For Macintosh: The following instructions were tested with Mac OSX 10.8.2 running Safari. For different versions of OSX or other web browsers, the steps may be slightly different.
You should see the following window. To make the images easier to see, you can enlarge the window. To see only one plane enlarged, click View/Axial Only. For Linux (or if the above instructions don't work): please go to http://www.mccauslandcenter.sc.edu/mricro/mricron/install.html You are on your own for installation! REQUIRED Step 2: Explore the brain and learn structures found in labs 8 and 9Regardless of the platform (PC or Mac), the top left of the window shows a coronal view of the brain. The top right of the window shows a sagittal view of the brain. The bottom left of the window shows an axial (horizontal) view of the brain. Click the mouse at any brain location to move the blue viewing crosshairs. The dataset name is listed at the top of the MRIcroN window in Windows, at the bottom of the window for Mac. The correct brain to view is the "ch2" file (ch2.nii.gz). Load this file by selecting "File/Open/Templates/ch2.nii.gz". At the top of the program window are three boxes labelled "x", "y" and "z" that show the brain location. Enter each of the co-ordinates (x,y,z) listed below into MRIcron. This will take you to the structure whose name is on the first column. This material will make up part of the testing materials for these laboratories (lab exams).
