Value Of Magnesium Sulfate As An Oral Contrast Medium For MRI Inspection Of Small Intestine Diseases

Objective:To explore the value of the magnesium sulfate as an oral contrast medium for small intestine magnetic resonance imaging (MRI) and the diagnosis of the small intestine diseases and to discuss the status and the development prospect of the MRI inspection of the small intestine diseases comparing with the double contrast barium. Materials and Methods:1. the selection of the Contrast MediumThe water, as the frame of reference, and the magnesium sulfate with different concentrations were scanned with the same identical MR sequence. After study and comparison of the signals of magnesium sulfate with different concentrations, the ideal concentration of magnesium sulfate was defined for small bowel MRI. On the same situation, volunteers were examined with MRI after drinking water or the magnesium sulfate with some certain concentration at different time and the result was analyzed.2. Clinical practice:Thirty-one patients with suspect of small intestine disease were studied by MRI and the double contrast barium to analyze the findings of the disease. The diagnosis was independently made by MRI doctors and radiologists. The MRI findings in 31 cases with small intestinal diseases were compared with findings of conventional intestinal enteroclysis and the results of pathology. The MRI manifestations of the different disease, the patient tolerance, the side affection and the complication, the clinical practice value of the magnesium sulfate as an oral contrast medium for small intestine magnetic resonance imaging were observed.
