For the study, divide the phantoms into two groups: (1) saline, saline+different kinds of contrast agent without 99mTc administration; (2) 99mTc administration: saline, saline+different kinds of the contrast agent with 99mTc administration. The CT contrast agent was used for Iopamidol® and Dotarem. And MRI contrast agent was used for Primovist® and Gadovist®. To obtain image, we used 3.0T MR System, and obtainedT1and T2 images. Using obtained image, we compared an average value of SNR of T1 and T2 before and after distributing 99mTc. As a result, SNR in T1 images had a significant difference before and after putting 99mTc to every contrast media except normal saline. Also SNR in T2 mages had a significant difference before and after putting 99mTc in every contrast media except Gadovist®.
