View angle tilting technique showed great reduction of image distortion from B0 inhomogeneity. With slice-encoding, namely SEMAC, enable MR imaging near metal object. One drawback is long scan time and diffuculty of applying on the high-field due to increased frequency range. To mitigate this problem, spiral sequence is considered and result showed VAT is applicable even on metal object.
