Abstract Title:
A Structured Survey on Adverse Events Occurring Within 24 Hours After Intravenous Exposure to Gadodiamide or Gadoterate Meglumine: A Controlled Prospective Comparison Study.
Abstract:
OBJECTIVE: This study compares the incidence of new-onset symptoms within 24 hours after enhanced magnetic resonance imaging (eMRI) with intravenous administration of gadodiamide or gadoterate meglumine compared with a control group undergoing unenhanced MRI (uMRI).MATERIALS AND METHODS: A prospective cohort study (n = 1088 patients) was designed to assess the incidence of symptoms within 24 hours after administration of gadodiamide or gadoterate meglumine. The participants underwent a structured questionnaire by phone call before and 24 hours after the MRI scan to check for symptoms that were not present before the scan. The questionnaire included a list of active questions aimed to test the prevalence of symptoms that have been proposed in the debated definition of gadolinium deposition disease (GDD) and that we recorded in this study as GDD-like. In particular, the following symptoms and signs were tested: central torso pain, arm or leg pain, bone pain, headache, skin redness (any site of the body), fatigue, and mental confusion.Fisher exact test was used to test differences between groups with significance threshold set at P
