Research Abstract |
We developed q-space method for clinical devices as a new imaging sequence in MRI-Diffusion Weighted Imaging (DWI) and we inspected it about phantom and an experiment volunteer to apply it to the real clinical patient and optimized a q-space sequence. We used methods hermaphrodite differentiation deleted q value (conventional high-b value) collection data in normal volanteer and to be similar with second curves for optimization of a q-space sequence. For standardization, we judged reliability of the value that we standardized by what approximate calculation compared with a done signal value on the basis of the degree of signal attenuation by instrumentation for the value that it lasted for long time, and measured q value data acquisition by q-space method in new normal volante a and a short time of the interval that had a short it. We improved reliability of the value that standardized this repeatedly.
