摘要：
The present invention relates to a magnetic resonance susceptibility difference compensation filter and a method for compensating for a magnetic susceptibility difference using the same. When a silicone pad having a silicone base with an added anti-curing agent is applied to a thyroid diffusion-weighted imaging test on a subject of invention, the improvement in the magnetic susceptibility difference and the optimal thickness at the time of the improvement were investigated through the changes in the distortion and error rate. As a result, with respect to the error rates in left and right lobes of the thyroid of the subject of invention before and after the application of the silicone pad, the error rates in both of the left and right lobes were smaller after the application of the silicone pad rather than before the application of the silicone pad, and with respect to the optimal thicknesses of the left and right lobes of the thyroid according to the thickness change of the silicone pad, the one-way analysis of variance results showed that the thickness of the silicone pad was not statistically significant in either of the left or right lobes when 2 cm or greater, and thus it can be seen that the optimal thickness is 2 cm. In conclusion, as shown in the present invention, the compensation of the curve portion of the human body, which is in contact with air, using the silicone pad can reduce the magnetic susceptibility difference between the tissue and the air without affecting the contrast of the magnetic resonance signal, thereby obtaining images having high diagnostic values and reduced image distortion at the time of thyroid diffusion-weighted imaging.La présente invention concerne un filtre de compensation de différence de sensibilité de résonance magnétique et un procédé pour compenser une différence de susceptibilité magnétique l'utilisant.
