To examine the effects of removing the gastroinal signal in MRCP, investigations were carried out on the combined use of intestine-positive contrast medium FerriSeltz with Ferric ammonium citrate as the main component and high-speed imaging using fast inversion recovery. The contrast effect was significantly elevated to 9.90±1.77 after administration, compared with 5.3±2.45 before administration (P<0.001). The enhancement effect also was significantly elevated to 14.45±3.18 after administration, compared with 3.50±3.10 before administration (p<0.001). These results were obtained because the null point of FerriSeltz aqueous solution (5.97 mmol/1) was in the range of about 150-200 ms. With the present method, adequate suppression of the signal intesity of the digestive tract was obtained relatively easily on MRCP, and the thechnique was found to be effective.
