| To examine the effects of removing the gastrointestinal 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 intensity of the digestive tract was obtained relatively easily on MRCP, and the technique was found to be effective. |
