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 applying the silicone pad rather than before applying the silicone pad, and with respect to the optimal thicknesses of the left and right lobes of the thyroid according to the thickness change in 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 greater or equal to 2 cm, 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.본 발명은 자기공명 자화율 차이 보상필터 및 이를 이용한 자화율 차이 보상방법에 관한 것으로서, 실리콘 베이스에 경화방지제를 첨가한 실리콘 패드를 발명 대상자에게 갑상선 확산강조영상 검사에 적용 시, 튀틀림과 오차율 변화를 통해 자화율 차이의 개선여부와 개선 시 최적의 두께를 알아본 결과, 실리콘 패드 적용 전ㆍ후에 따른 발명대상자의 갑상선 좌엽과 우엽의 오차율은 좌엽과 우엽 모두 실리콘 패드 적용 후가 적용 전에 비해 오차율이 적었고, 실리콘 패드의 두께변화에 따른 갑상선 좌엽과 우엽의 최적두께는 일원배치분산분석 결과, 실리콘 패드의 두께가 2cm 이상부터 좌엽과 우엽 모두 통계
