The non-Cartesian sampling can obtain the image even for the number of data that does not satisfy Nyquist, but the under-sampled image is accompanied by streak artifact. Since the non-selective pulse used in conventional 3D radial UTE(C-UTE) is excite unwanted areas out of FOV, streak artifacts may appear in the image when under-sampling. Volume-Select UTE(VS-UTE) performs spin excitation using frequency-selective SINC pulses. Accordingly, the proposed method effectively suppresses the signal outside the FOV, which reduces streak artifacts. The purpose of this study is to introduce a VS-UTE sequence and to confirm that the streak artifacts are reduced effectively.
