This is a ~52 minute QuickTime clinical anatomy video displaying highlights from a 3D high-resolution Brachial Plexus MRI/MRA of a patient with bilateral Thoracic Outlet Syndrome (TOS), interpreted by James D. Collins, MD (UCLA Radiology). BEWARE - this file is huge (194 Mbytes = 1552 Mbits), and takes about 30 to 50 minutes to download using DSL or a cable modem, depending on your download speed. If you are using a dialup modem (phone line), it could take over 15 hours to download (this assumes 28 kbps download speed, which is about average for a 56K modem)! In this case, try asking a friend or relative with DSL or cable modem to download it and burn to CD for you.

The download file is compressed (zipped), and you will need a program to unzip the file. There are several free programs which can unzip, such as WinZip (for PC - get the free evaluation version, install WinZip Wizard which automatically unzips files when you click on them) and StuffIt Expander (for multiple platforms, including Mac, Windows, Linux, Solaris). Alternatively, if you have pkunzip (on PC), you can use it to unzip the file from a DOS prompt.

You will also need a QuickTime Player to view the video. If you have a Mac, it's probably already installed on your computer.

After the download is complete, unzip the file (MRI.zip) to extract a file called "3D-MRI.mov". [Once you have the *.mov file, the zip file can be deleted.] Double click on this file, and a QuickTime Player should pop up with the movie loaded. Press the play button (>) to start the movie.
