1) Go to the mriSims website (104.236.6.144/caolman/mriSims 2) Send a good thought Andrea's way to thank her for making this website! 3) Choose a FLASH pulse sequence and the phantom with fat ... run. 4) Decrease the bandwidth to 25000 and run. What happened to the image? Is the read-out direction left-right or up-down? 5) Decrease the bandwidth to 5000 and run. Why did you have to increase TE (and then TR ...) in order to run? 6) Switch to EPI and set bandwidth back to 100000 and run (after adusting TE and TR accordingly). Describe the "fat ring" now.
