Abstract

Fig. 2 and 3 shows a part of the magnitude, wrapped phase and high-pass-filtered phase images of each T1FFE and T1FFE with shifted echo. Imitation calcifications on the phase images appeared as areas with hyperintensities. Imitation calcifications on high-pass filtered phase images were visualized from 3 to 2 mm. Fig. 4 shows phase values of the imitation calcification on phase images of T1FFE and T1FFE with shifted echo as a function of the changed TE. In the T1FFE, while TE became longer, the phase value of imitation calcification became higher, but in the T1FFE with shifted echo, it was almost changeless. The phase values of T1FFE and T1FFE with shifted echo were crossed near TE of 13 msec.
