Iron Supplements in Suppressing Gastric Signal on MRCP

Abstract

The biliary system image on MRCP examination is often disrupted by artifacts due to signals from the stomach and duodenum. To eliminate this signal artifacts, an intra-oral negative contrast medium is required. On the market there are artificial contrast media but have a price that is quite expensive, and difficult to obtain. Iron supplement solutions have a paramagnetic iron content so they can be used as a substitute for negative contrast media sold on the market. To analyze the differences in gaster SNR values ??on MRCP examination between before and after administration of Iron supplement solution as an alternative to negative oral contrast media. This type of research is quasi experimental with Pre-test Post-test design. The subjects of the study used 10 samples of healthy volunteers by doing scaning pre-contrast, post contrast Scaning protocol uses HASTE Fat Saturation T2 Coronal Thick Breath Hold. The result of the image is measured by the signal value to calculate the SNR ??and then do a different test. There were differences in gastric SNR values ??between Pre Contrast with post contrast (p-value < 0,001). Iron supplement solutions can be used as negative oral contrast media for MRCP examination.
