Abstract

The purpose of this experiment is to know the relation of the detection and characterization of liver's diseases as comparison of finding at MR imaging using a Ferucarbotran (SPIO) and Gd-EOB-DTPA (Primovist) agents in diffuse liver disease. A total of 50 patients (25 men and 25 women, mean age: 50 years) with liver diseases were investigated at 3.0T machine (GE, General Electric Medical System, Excite HD) "with 8 Ch body coil for comparison of diseases and contrast's uptake relation, which used the LAVA, MGRE." All images were performed on the same location with before and after Ferucarbotran and Gd-EOB-DTPA administrations (p<0.05). Contrast to noise ratio of Ferucarbotran and Gd-EOB-DTPA in the HCC were $3.08{\pm}0.12$ and $7.00{\pm}0.27$ with MGRE and LAVA pulse sequence, $3.62{\pm}0.13$ and $2.60{\pm}0.23$ in the hyper-plastic nodule, $1.70{\pm}0.09$ and $2.60{\pm}0.23$ in the meta, $2.12{\pm}0.28$ and $5.86{\pm}0.28$ in the FNH, $4.45{\pm}0.28$ and $1.73{\pm}0.02$ in the abscess and ANOVA test was used to evaluate the diagnostic performance of each disease (p<0.05). In conclusions, two techniques were well demonstrated with the relation of the detection and characterization of liver's diseases.

다양한 간 질환에 Ferucarbotran (SPIO)과 Gd-EOB-DTPA (Primovist) 조영제를 사용하여 자기공명영상 상에서 비교하여 간 질환의 특성 및 검출 과 그 질환에 따른 조영제 흡수관계를 알아보고자 한다. 실험대상은 국소 간 병변을 가진 50명의 환자 중 남자 25명, 여자 25명으로 평균나이는 50세이었다. 사용된 장비와 코일은 3.0T (General Electric Medical System, Excite HD) 자기공명영상장치와 8채널 채부코일이었다. 질환과 조영제 흡수관계를 비교하기 위하여 사용된 펄스 시퀀스는 Liver aquisition with volume acceleration (LAVA)와 Multi-Gradient rapid Echo (MGRE)이었다. 모든 검사기법은 일정한 데이터를 획득하기 위하여 Ferucarbotran (SPIO) 및 Gd-EOB-DTPA (Primovist) 조영제를 주입 전 후에 같은 위치를 선정하여 검사를 시행했다(p<0.05). 검사 결과는 Ferucarbotran와 Gd-EOB-DTPA의 대조도대 잡음비는 간세포암(HCC, 16 cases)이 $3.08{\pm}0.12$과 $7.00{\pm}0.27$이었다. 과다형성결절(Hyperplastic Nodule, 7 cases) 질환은 $3.62{\pm}0.13$, $2.60{\pm}0.23$, 전이(Metastasis, 13 cases)는 $1.70{\pm}0.09$, $2.60{\pm}0.23$, 초점성 결절성 과증식(Focal Nodular Hyperplasia, 6 cases)질환은 $2.12{\pm}0.28$, $5.86{\pm}0.28$, 농양(Abscess, 8 cases)은 $4.45{\pm}0.28$, $1.73{\pm}0.02$이었다. 또한, 각 질환에 대한 진단적 수행을 위해 ANOVA 검증을 하였다(p<0.05). 결론적으로, 두 조영제 효과로 2개 검사기법 모두가 간질환의 특성 및 검출과 그 질환에 따른 조영제 특성을 잘 보여주었다.
