View larger version (91K): [in a new window]   Figure 2 (A,B) Magnetic resonance turbo-spin-echo images obtained at 1.5 T in a patient with monomorphic right ventricular extrasystoles. Long-axis view demonstrating high-signal intensity at the apex of the right ventricle (arrow), without (A) and with (B) spectral fat saturation. Image A acquired without spectral fat saturation, shows high-signal intensity within the right ventricle apical wall due to the presence of fatty tissue. When the same image is acquired with spectral fat saturation (B), the high-signal intensity of fatty tissue disappears, and the fatty replacement is imaged as an area of signal void within the right ventricle.
