A magnified region is shown in the lower right corner of each image to illustrate the signal in epicardial fat surrounding the apex of the left ventricle

The phase-modulated 1-(90°)-1 WE-SSFP sequence decreases the fat to myocardium signal ratio and provides a valuable method of differentiating fluid from adipose tissue. All figures are displayed with the same window and level settings.<p><b>Copyright information:</b></p><p>Taken from "Rapid phase-modulated water excitation steady-state free precession for fat suppressed cine cardiovascular MR"</p><p>http://www.jcmr-online.com/content/10/1/22</p><p>Journal of Cardiovascular Magnetic Resonance 2008;10(1):22-22.</p><p>Published online 13 May 2008</p><p>PMCID:PMC2429911.</p><p></p

Note the significant suppression of signal in the mass in the WE-SSFP image (b), clearly indicating this as adipose tissue

Top two rows demonstrate measured frequency response functions in a uniform water phantom for conventional slice-selective RF pulse, 1-(180°)-2-(180°)-1, 1-(180°)-1, and 1-(90°)-1

All four sequences were run with TR = 9.68 ms and constant gradient offset of 0.0723 mT/m left-to-right to illustrate the signal over a range of offset frequencies. Middle row shows the signal profile across the phantom for each of the corresponding images. The white line across indicates the location of the signal profile measurement for each image. Bottom row shows simulated frequency response functions for the same four sequences used to generate the phantom images and signal profiles . Reasonable agreement is observed between phantom measurements and simulation results.<p><b>Copyright information:</b></p><p>Taken from "Rapid phase-modulated water excitation steady-state free precession for fat suppressed cine cardiovascular MR"</p><p>http://www.jcmr-online.com/content/10/1/22</p><p>Journal of Cardiovascular Magnetic Resonance 2008;10(1):22-22.</p><p>Published online 13 May 2008</p><p>PMCID:PMC2429911.</p><p></p

The fat frequency falls within the stopband in each case, indicating that fat suppression is independent of sequence TR
