FIG 2. Four-echo t-PEPSI images (TR/TE1/TE2/TE3/TE4/NEX = 5000/23/64/105/145/1, flip angle = 90°).

A, On the first-echo image, susceptibility effects of the lesion have not affected the image contrast to a great extent.

B, Best lesion-to-tissue contrast is obtained around 50 msec.

C and D, At longer TEs, contrast is lost.
