A dose study was performed of MRI intravenous contrast medium enhancement of rheumatoid synovium in the knee, comparing the enhancement with gadoteridol at doses of 0.1 and 0.3 mmol/kg. A measurable and significant difference was demonstrated which has particular relevance to the accuracy of dose calculations needed when performing quantitative studies.
