High SNR MR venography of the lower
extremities was obtained using bTFE DIXON sequence. The water-fat slice swap
artifacts observed in the original bTFE DIXON were well corrected by applying HISSCO,
the proposed post-processing technique.

MIP images of (a) SPIR T1TFE, (b) bTFE DIXON without HISSCO, and (c)
bTFE DIXON with HISSCO applied. Multiple slice swaps observed below the knee in
the original bTFE DIXON (arrow) were all corrected by HISSCO. Note that the most
distal swap in (b) happened only on the right side of the leg but nicely
corrected in (c).
