Abstract:
OBJECTIVE:To evaluate the value of oral ferric ammonium citrate solution as a gastrointestinal contrast agent in diagnosing low-level obstructive jaundice.
METHODS:Thirty-six patients who were suspected of low-level obstructive jaundice were performed with magnetic resonance cholangiopancreatography (MRCP) and conventional MRI before and after the administration of oral ferric ammonium citrate solution. The diagnostic accuracy for evaluating the site and the cause of obstruction was compared with other diagnostic modalities.
RESULTS:The image qualities of single-slice and multi-slice MRCP were improved markedly. The accuracy of MRCP for evaluating the site of obstruction was 97.22%, which was superior to US (P<0.05). There were no significant differences among the MRCP, CT, and ERCP.
CONCLUSION:Oral ferric ammonium citrate solution can significantly improve the image quality of MRCP. FAC-MRCP is a simple, safe, and noninvasive technique with excellent accuracy in the diagnosis of low-level obstructive jaundice.
